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.

Research Themes

Jayson's research aligns to the University's research theme of Marine, Antarctic and Maritime. He conducts research that advances our understanding of marine ecosystems, while promoting sustainable management of marine resources. Jayson is particularly interested in assessing the role of animal energetics; activity/behaviour; and environmental change as key processes structuring marine populations; influencing life history parameters; and ultimately influencing survival.

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.

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).

Sense-T Stage 2: Sensing Macquarie Harbour (2015 - 2016)$677,100
Description
This Sense-T project brings together the Tasmanian Salmonid Growers' Association, IMAS and CSIRO to collect and analyse data from salmon farms in Macquarie Harbour. Sensors will be attached to individual 'sentinel' fish in pens in addition to sensors in the environment. Data will be collected on fish behaviour as well as environmental conditions such as water temperature, dissolved oxygen and depth. This will: help to reduce feed wastage by ensuring fish are fed when environmental conditions are suitable; collect new or previously difficult to obtain information about the harbour environment and the impact of salmon farming on variables such as oxygen levels; improve the salmon industry's efficiency and productivity; provide real-time data to support decision-making; and, highlight areas where the industry could improve its environmental practices.

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.
