Associate Professor Jayson Semmens works in the Fisheries and Aquaculture Centre at the Institute for Marine and Antarctic Studies, University of Tasmania, where the focus is on sustainable fisheries biology/ecology. In particular, his work focuses on applying biotelemetry, biologging, accelerometry and ecophysiology to understanding marine populations and ensuring their sustainability. He is particularly interested in using these techniques to examine factors that influence the expression of life history parameters across a wide range of animal groups, particularly sharks and rays, fish, and cephalopods. He also has extensive expertise/interest in scallop fisheries biology/ecology.

Biography

Assoc. Prof. Semmens arrived at IMAS in November 1999 after completing a PhD at James Cook University in Cephalopod Biology. He was awarded an ARC Postdoc in 2001 on Octopus biology/ecology, which he completed in 2004. Since then, he has developed research programs in spatial ecology and ecophysiology, predominately focused on fish, sharks and rays; scallop fisheries biology/ecology; and effects of seismic surveying on invertebrates.

Jayson has authored more than 70 peer-reviewed publications, including one in PNAS and one in Nature Climate Change. He has sourced >$7.5 M in research funding, including Category 1 Grants (FRDC Grants; ARC Discovery, Linkage & Infrastructure Grants). He has also been awarded two Japanese Society for Promotion of Science Fellowships for his work using accelerometry to examine feeding ecology in sharks.

He conducts innovative and inter-disciplinary field and laboratory-based research to address questions critical to gaining an understanding of marine populations and ensuring their sustainability. He is particularly interested in factors that influence expression of life history parameters, such as growth, fecundity, mortality rates and reproductive scheduling. Some of the main research tools he employs are biotelemetry, biologging, accelerometry, respirometry and histology. He works across a wide range of animal groups, particularly sharks and rays, fish, cephalopods and scallops.

The reproductive health of the endangered Maugean skate: steps towards conservation (2023)$48,302

Description: The Maugean skate, Zearaja maugeana, is an Australian species endemic to one isolated western Tasmanian estuary, theonly remaining stronghold for the species. Based on their limited geographic range and decreasing population size, the species is listed as endangered.The species' habitat is a highly anthropogenically impacted system. One of the main effects of marine contamination is the failure of the reproductivesystem. Reproduction is the primary requirement for successful propagation of any species, failure to reproduce will result in a major conservationproblem limiting the species capacity to contribute to future generations. We have already witnessed a decrease in Maugean skate populationsize and absence of juvenile individuals, possibly as a result of reproductive failure over the years, placing the species under risk of extinction. We mustunderstand the reproductive capacity and consequent future survival of the species to ensure the implementation of effective conservation plans

Capture stress and post-release survival of thresher sharks: contributing to developing best-practice for catch and release game fishing (2023)$26,555

Description: This study will directly examining post-release survivorship of thresher sharks (Alopias vulpinus) released by recreational game fishers and quantify physiological indicators of capture stress and relate these to capture data (e.g., shark size, fight time, SST, capture gear). Game fishing associations are keen to release these sharks upon capture and contribute to their conservation, but there is currently no data as to the survivorship of released sharks to show that this approach has merit. This study will provide such data and assist game fishers to refine their practices, such that survivorship is maximised. If the data showed, however, that the practice should not be undertaken as mortality rates are high, the results of the study would also provide the basis for the Government to review the status of the fishery.

Assessing the effectiveness of artificial reefs and FADs in creating recreational opportunities for Tasmanias recreational fishers (2022 - 2023)$369,000

Description: An Election Commitment 'Taking Recreational Fishing and Boating to the Next Level' has provided $1.0M over the next two years to install artificial reefs in Tasmania. There is also an addition $450K for the installation and management of Fish Aggregation Devices (FADs) that will provide a new range of fishing options for recreational and sport fishers (total $1.45M). his commitment aligns with the strategic direction of recreational sea fishing, 'Towards a 10 Year Vision for Recreational Sea Fishing in Tasmania', where Outcome 3 'Making it easier for people to go fishing' identifies infrastructure projects that can enhance fishing opportunities a priority, such as installing artificial reefs and FADs. Marine and Safety Authority Tasmania (MAST) has been tasked with implementing this Election Commitment on behalf of the Government, and Marine Solutions has completed feasibility assessments, including site selection, for the installation of both the artificial reefs and FADs: www.mast.tas.gov.au/artificial-reefs-and-fish-aggregation-devices-fads-in-tasmania. Marine Solutions is currently seeking government permits for two artificial reefs and five FADs in Tasmania, and installation will likely be open for tender in early 2021. It is expected that installation at all sites will be completed towards the end of next financial year (2021). Upon completion, all equipment ownership and ongoing management will be transferred to Department of Primary Industries, Parks, Water and Environment (DPIPWE). Currently, there is no pathway to determine the direct and in-direct benefits these resources may have for the recreational fishery and other multi-sector users. This includes the role these resources play for Tasmania's unique fish fauna, and their specific habitat and nursery requirements. It is vital that we invest into measuring these contributions to, ultimately, determine value and potential "success". Information can be used for ongoing management to ensure long-term benefits are maximised. This project is endorsed by RecFAC & will be carried out in collaboration with the recreational fishery (TARFish), MAST and DPIPWE.

Can novel seismic survey sources mitigate potential impacts to fisheries? (2021 - 2023)$998,608

Description: 3D Marine seismic surveys (MSS) are typically used by the petroleum industry to locatepotential oil and gas deposits. In Australia, the National Offshore Petroleum Safety and EnvironmentalManagement Authority (NOPSEMA) requires an Environmental Plan (EP) be developed to demonstrate that theMSS will be carried out in a manner that is consistent with the principles of ecologically sustainable development,and that the environmental impacts and risks associated with the MSS will be reduced to as low as reasonablypracticable. However, during the public consultation phase of the EP, there is often a perceived conflict betweenthe proponents of the survey and the fishing industry, with the later party often concerned that the survey willharm the fishery stocks and their livelihoods. As such, there is a need to break the continual cycle where each EPseemingly triggers the same ill feeling and distrust from the fishing industry. One possible way to do this is tointroduce new seismic sources or ways of using current sources, such that some or all of the potential impactsare mitigated. While there are new seismic sources and source designs that should lessen any impact onanimals, these have not been tested with animals anywhere in the world and have never been tested or used inAustralia in general and only sparsely overseas. As such there is an urgent need to compare a current industrystandard seismic array to arrays using alternate sources of seismic signals or different source designs todetermine the relative impact of each on marine animals, while also comparing the quality of the geophysicalrecords obtained from each source. This approach would put Australian fisheries management, NOPSEMA,Australian Oil and Gas, the fishing industry, etc. ahead of the game of determining what alternate sources willreduce conflict between two key industries. It would also move us into a position to start mitigating the impacts ofseismic surveys, rather than the situation we currently have, where each individual seismic survey causes a largeamount of angst between a large number of stake holders.

Wider investigation of the use of video survey techniques to determine commercial scallop abundance in inshore and offshore waters, closed areas and juvenile beds (2021 - 2023)$355,509

Description: The Tasmanian Scallop Fishery contains a network of scallop dredge prohibited areas and shark refuge areas where commercial harvesting of scallops is not allowed. Scallop dredging is also prohibited in waters less than 20 m deep. These areas contain an unknown scallop biomass that may contribute to recruitment into areas accessible to scallop dredging. A recent towed video scallop survey of Great Oyster Bay undertaken by IMAS demonstrated the utility of towed camera surveys in areas that are closed to scallop dredging. This survey was also able to demonstrate the ability of a towed camera to detect small scallops that otherwise would not be detected in a scallop dredge survey. Towed video surveys may also be able to be used in conjunction with dredge surveys to gain a wider understanding of the scallop population and seabed community structure (i.e. identify sensitive seabed habitat types) prior to commercial harvesting, and better define areas of very small scallops that should be avoided during a closed season. This project will provide a better understanding and knowledge of the scallop distribution and abundance in inshore waters that may contribute towards recruitment to waters available to the commercial scallop fishery. It aims to development of a towed video process to supplement commercial dredge surveys to assist with the identification of presence of very small scallops.

Towards conservation of the vulnerable Melbourne Skate: Assessing life-history and reproductive behaviour (2021)$2,000

Description: Given that large skate species are more prone to local extinction compared to smaller species, coupled with the already observed population declines, its high susceptibility to fishing pressure, and the lack of biological and ecological information, the large Melbourne skate may be particularly vulnerable to local extinction. As such, this project is important, as it addresses this lack of information to provide a starting point for conservation efforts for this vulnerable species. Specifically, we aim to define the species' (i) life history (age, growth, and reproduction), (ii) distribution and abundance in south-east Australia, (iii) population productivity, (iv) use of inshore protected areas, (v) candidate egg laying and nursery grounds and (vi) extinction risk and make this information available to resource managers.

NESP MaC 1.33: Application of environmental DNA (eDNA) to survey Bathurst Harbour Tasmania for the endangered Maugean skate (2021)$73,528

Description: This study will use eDNA to determine the presence of the endangered Maugean skate (Zearaja maugeana) in Bathurst Harbour on the southwest coast of Tasmania. Zearaja maugeana has been classified as endangered by the Australian Environment Protection and Biodiversity Conservation Act (1999) based on its small population size and restricted distribution, as it has only been reported from two remote estuarine systems in Tasmania, Bathurst Harbour and Macquarie Harbour on the west coast [25]. Initially discovered in Bathurst Harbour in 1988, Z. maugeana has not been recorded in that locality since 1992, with only four individuals ever sighted, despite extensive fishing and underwater visual surveys conducted over a number of years, with the most recent survey in 2016 [26]. The lack of confirmed sightings has raised considerable uncertainty as to the current status of the Bathurst Harbour population, implying either a very small population size or even localised extinction.Core record = J0028102

Understanding population structure and dynamics of Victorias developing Octopus fishery (2020 - 2024)$561,140

Description: In Victoria, Octopus spp. are predominantly a byproduct species caught across various fisheries. Pale Octopus is not differentiated from other octopus species in catch and effort reporting in Victoria, making it difficult to apply stock assessment methods or catch rate indicators. Maori Octopus (Octopus maorum) are likely caught in the Victorian Rock Lobster Fishery (VRLF); whereas Pale Octopus and Gloomy Octopus (Octopus tetricus) are caught within the Inshore Trawl Fishery, Ocean Access Fishery (OAF), Corner Inlet Fishery (CIF) and Port Phillip and Westernport Bay Fishery (PPWPBF). Targeting octopus using 'shelter traps' within the OAF off Lakes Entrance has significantly increased in 2016 and 2017. The average catch during this period was ten times greater compared with the average catch taken from 2006-2015 with the potential for a developing fishery, management is lacking fundamental information to assist in guiding and building a sustainable fishery. For example, there is no requirement to identify and report quantities of species caught. This makes any sort of assessment impossible. Presently, two license holders actively fish for octopus with a capacity to have many more within the OAF.

Life-history and reproductive behaviour of the vulnerable Melbourne skate to inform fisheries management and conservation (2020 - 2022)$42,626

Description: Given its large body-size, with Dulvy and Reynolds (2002, Cons Biol 16:440) finding that skate species that have suffered local extinction have large body sizes compared with all other skates, coupled with the already observed population declines, its high susceptibility fishing pressure and the virtual complete lack of biological and ecological information, the Melbourne skate may be particularly vulnerable to local extinction. As such, this project aims to address this lack of vital information available in order to guide conservation efforts for this vulnerable species. Specifically, we aim to define the species' (i) life history (age, growth and reproduction), (ii) distribution and abundance in south-east Australia, (iii) population productivity, (iv) use of inshore protected areas, (v) candidate egg laying and nursery grounds and (vi) extinction risk.

Examining the potential impacts of seismic surveys on octopus and larval stages of Southern Rock Lobster (2020 - 2022)$606,770

Description: CGG has NOPSEMA approval for a 3D seismic survey in the Gippsland Basin to commence in early 2020. This survey overlaps the Victorian shelter-pot octopus fishery off Lakes Entrance. This overlap has raised concerns about the potential impacts to octopus and the fishers from the survey. Tank-based experiments simulating seismic exposure have resulted in high levels of damage in several species of octopus, however, it is unclear how experiments conducted in tanks translate into the field. Field-based seismic experiments are rarely conducted on invertebrates, however, a recent study by the applicants (FRDC 2012-008) demonstrated significant impact on scallops from seismic signals. Like scallops, the benthic and relatively sessile habit of octopus leaves them potentially vulnerable to impacts, as they have limited capacity to avoid the waterborne and ground-borne energy of seismic signals. CCG has acknowledged these potential impacts and is supporting this research, through the formation of a Scientific Advisory Committee, a cash contribution and the use of a full seismic survey, with the lack of a full array often a limitation of seismic research. This project will use a field and laboratory experimental approach to provide a thorough assessment of the potential impacts of seismic surveys on octopus pallidus (the primary species captured in the fishery) in the natural environment, as a model species for octopus fisheries. Additionally, the project will examine the potential impact of the seismic survey on octopus catches and catch rates. These approaches will assist octopus fisheries and petroleum regulators to make informed decisions on the timing and manner in which future surveys are performed. Importantly, along with that of CGG, it has the support of the Victorian Fisheries Authority, who have also offered in-kind support, the two octopus fishers in the region, the Lakes Entrance Fishermen's co-op and the sustainable shark fishing association.ObjectivesNo.Details1Determine the impact of intense low frequency acoustic signals on adult pale octopus (Octopus pallidus)2Determine the impact of intense low frequency acoustic signals on the development of eggs, hatching rates and competency of the resultant hatchlings.3Outline threshold distances for potential impacts of seismic surveying4Determine the impact of intense low frequency acoustic signals on pale octopus (Octopus pallidus) catch.

The impacts of climate change on behaviour and physiology of key elasmobranch species in Southeast Tasmania (2020 - 2022)$19,635

Description: This research meets the HERDC five core criteria as there is limited behavioural and physiology research pertaining to fluctuating temperatures, especially compounded with changing salinities, that has been conducted on these species, as well being the first study to measure the rates of protein synthesis (PS) in elasmobranchs (1: novel & 2: creative). Because this is the first research of its kind on these sharks and rays, as well novel in measuring elasmobranch PS rates, the final outcomes are uncertain as the response to stressors varies across species and rates of PS are unknown (3: uncertain). The ideas and proposals for this research have been outlined in a project plan which also includes a detailed budget to prepare for the total cost of the project in advance (4: systemic). All research methods will be recorded and reported, including novel PS procedures, and data will be presented in an understandable and accessible way to allow for reproduction of research or procedures with other species (5: transferable/reproducible).

Monitoring and assessing offshore production structures (2020)$49,972

Description: The expansion of aquaculture/energy production into offshore areas requires the development of science-based automated environmental monitoring platforms. These platforms are important for maintaining public confidence in the associated industry and will reduce the operational costs and risks. Developing these platforms is contingent on ensuring that the environmental footprint and associated monitoring tools are well understood. This project will conduct a systematic review of the literature and consult with stakeholders (e.g. industry, government regulators), to identity the relevant parameters and technologies needed to develop these systems. The results will help to meet the end needs of the expanding industries and the government.

Mechanisms and consequences of a climate-driven range extension of snapper (Chrysophrys auratus) in southeast Australia (2019 - 2020)$33,666

Description: This research will investigate the ecological consequences of climate-driven marine species range shifts. Globally, species are shifting poleward with rising temperatures, which has critical impacts on ecosystems and humans that depend on them. A key focus of climate change biology is understanding and predicting the consequences of ongoing and future range shifts. However, attempts to date to understand and predict effects of range shifts have been hindered by the scalability of laboratory studies and a lack of mechanistic insight from field observational studies. Using the contemporary range extension of snapper Chrysophrys auratus in the south-east Australian 'ocean warming hotspot' as a case study we are investigating: (1)Which mechanisms underpin range extensions (e.g. thermal tolerance, reproduction and migration)?(2)What are the resulting consequences (e.g. altered growth rates, ecosystem impacts)?

Uncoupling oceanographic and life history drivers to alternate foraging strategies in Long-nosed fur seals (2017)$3,000

Description: Long-nosed fur seal (LNFS, formerly New Zealand fur seal, Arctocephalus forsteri) breeding range in South Australia is distributed across a relatively small geographic area characterized by a southern distribution, associated with narrow shelves in proximity to localized seasonal coastal upwelling in summer and autumn. Early in lactation (December to March), females undertake short foraging trips (~4 days duration) to near shelf waters (70-90 km the colony), in regions associated with localised upwelling. However, between April to May females switch to foraging in distant oceanic waters 700-1,000 km to the south of breeding colonies, associated with the Subtropical Front (STF), where they continue to forage until the weaning of their pup in September/October. These winter foraging trips can last more than two weeks. It is unclear if this major shift in foraging distribution occurs in response to: 1) reduced prey availability as a consequence of cessation in coastal upwelling; 2) life-history/pup growth factors that enable females to switch to more reliable but distant foraging grounds once their pup reaches a size and condition threshold where they can sustain longer fasts; or 3) a combination of these factors.Understanding the role of the in-situ oceanographic and life history factors in shaping alternate summer and winter foraging strategies is the central focus of this study. Changes in shelf oceanographic features associated with fur seal foraging areas will be monitored using a novel approach, by simultaneously fitting biologging tags to fur seals and oceanographic (CTD/Fluorometer/Irradiance) tags onto Australian sea lion males. Sea lions forage over shelf waters year round and sample the entire water column, providing a means to monitor changes in local oceanographic conditions from the summer to winter period.

Understanding oxygen dynamics and the importance for benthic recovery in Macquarie Harbour (2017 - 2020)$3,679,698

Description: Sustainable finfish aquaculture is dependent on a benthic environment that can assimilate and process farm particulate wastes. This project will help inform the likely effectiveness and duration of any given fallowing or remediation strategy, and as such is essential for both operational management of farming activities and the long-term management of the harbour. This will involve a combination of benthic surveys, a real time observation network and oxygen transport modelling. The central outcome of this research will be better advice on appropriate fallowing and remediation strategies for the conditions currently occurring in Macquarie Harbour. Robust scientific understanding of benthic and water column condition in the Harbour, with a particular focus on dissolved oxygen dynamics in the water column, will provide a much better appreciation of the response of benthic communities to fallowing and remediation strategies.

Putting potential environmental risk of Australia's trawl fisheries in landscape perspective: exposure of seabed assemblages to trawling, and inclusion in closures and reserves (2016 - 2018)$281,019

Description: Addressing & demonstrating the environmental sustainability of fishing particularly trawling remains amajor challenge & priority in management plans for many demersal fisheries in Australia. The effects of trawling (EoT) are contentious, with often negative perceptions among the public & media, thus impeding social licence to operate. Australian fisheries must meet legislative requirements under the EPBC Act & regular environmental assessment by the Department of Environment. Environmental Risk Assessment(ERA) approaches have been used for assessing EoT in response to EPBC Assessment requirements, primarily for bycatch at a qualitative or semi-quantitative level. However, EPBC Principle 2 / Objective 3 (minimize impacts on the ecosystem, including habitats & communities) has rarely been addressed & almost never quantitatively. These shortcomings limit the goal of ensuring no unacceptable impacts on ecosystems. Further, the annual Fishery Status Reports aim to include broader environmental reporting & the Healthcheck project (FRDC 2014/008) has identified suitable indicators, such as habitat footprint (e.g. % exposed tofishing).

Developing conservation management strategies for vulnerable deepwater sharks off south-eastern Australia (2015 - 2016)$10,000

Description: Deepwater sharks are particularly vulnerable to human impacts due to late age maturity, low fecundity and low natural mortality. These species are particularly difficult to manage because the ability of populations to compensate for any additional human induced mortality is so low that they remain vulnerable, even as by-catch. Not surprisingly, a number of species have been overfished in the Atlantic, Indian and Pacific Oceans. Off SE Australia declines of more than 99% for two species in some areas have resulted in nomination for protection under the EBA Act.

Life History and Population Dynamics of the Range Extending Octopus tetricus in south-eastern Australia (2013)$6,000

Description: Anthropogenic climate change is resulting in warmer waters that are altering the distribution, abundance and life history of many marine species. In south-eastern Australia, the East Australian Current is extending further into Tasmanian waters and persisting for longer periods throughout each year. Consequently, the Tasman Sea is warming at three to four times the global average and contributing to the shift in distribution of several dozen benthic, demersal and pelagic species (Pitt et al. 201 0; Johnson et al. 2011 ). One of these species is the ecologically and commercially important Sydney octopus, Octopus tetricus, which is commonly distributed from southern Queensland to central NSW. As waters have warmed over the last seven years this octopus has been detected along the coasts of Victoria and Tasmania, indicating a very large apparent range shift, with the potential impacts on local marine ecosystems largely unknown. Despite range shifts being documented all over the world, there are large gaps in our understanding of the mechanisms underpinning range-shift dynamics, the evolutionary consequences and how genetic traits can modulate such shifts.

Assessing effectiveness of refuge areas for conservation of coastal sharks (2011 - 2013)$86,635

Description: This project seeks to extend work on investigating the role of sevengill sharks Notorynchus cepedianus in coastal areas of south east Tasmania. A major component of the current project is using acoustic technology to investigate the movement patterns of sevengill sharks within these coastal areas. This project will continue using acoustic technology to gather long term data on the movement patterns for the chondrichthyan assemblage of south east Tasmania. Due to the availability of long term infrastructure in the form of permanent VR2 receiver arrays deployed throughout south east Australia, this project has a unique opportunity to monitor long term and long distance movement patterns for several chondrichthyan species tagged with acoustic transmitters in south east Tasmania. Additionally this project aims to determine the size and age structure of juvenile shark populations in nursery areas by using stereo baited remote underwater video cameras (BRUVs) as a survey tool. This multi-species approach will address a range of relevant issues associated with managing and conserving chondrichthyans, such as identifying important habitats for chondrichthyan species, evaluating the effectiveness of protected areas, investigate long distance migrations and predicting predator-prey relationships. The project will have a strong emphasis on conservation and management of top order predators, and will provide optimal management strategies for a number of shark species. This project will address the need for a broader understanding of ecosystem issues in the management of commercial fisheries. For example, it will further build on the knowledge of species interactions in these systems by evaluating the impact of sevengill sharks on other shark species that are commercially fished. This information will assist in ecosystem management (as opposed to single species management) which should be the goal of all conservation and fisheries management plans.
