As a Research Fellow in Aquaculture I conduct research at the Experimental Aquaculture Facility at the Institute for Marine and Antarctic Studies (IMAS) (Taroona). I am particularly interested in the field of farmed Atlantic salmon growth performance as well as other biological and physiological aspects of the species


My scientific career path started in Italy, where I completed a BSc in Natural Sciences and a MSc in Evolutionary Biology and Ecology with focus on Aquaculture. At the end of 2012, after receiving an offer to undertake a PhD in Aquaculture at the University of Tasmania and then being awarded a University of Tasmania and Institute for Marine and Antarctic Studies “Tasmania graduate research scholarship”, I moved to Australia to begin a new journey. My PhD investigated the occurrence of skeletal deformities and their molecular mechanisms in triploid Atlantic salmon.

The molecular component of the project took place at the University of the Sunshine Coast (Queensland). A few months before being awarded my PhD on December 2016, I was employed as Aquaculture Scientist by Petuna Aquaculture, a salmon and trout producer in northern Tasmania, to design and run a $0.5 million Fisheries Research and Development Corporation (FRDC) project in partnership with the University of the Sunshine Coast. We investigated molecular mechanisms and genetic effect of flesh colour variation in Atlantic salmon as a result of warmer summer seawater temperatures.

The project produced critical novel results and led to the establishment of the Petuna Breeding Program which I coordinated for the last 3 years. At Petuna, I was also responsible for performance, welfare, and quality monitoring of freshwater stocks. After five years in the industry, where I had the opportunity to keep doing research and acquired a deep commercial knowledge of salmonids aquaculture, I joined UTAS to conduct research on salmon at the IMAS Experimental Aquaculture Facility

Skeletal development in King salmon, with an emphasis on intermuscular (pin) bones abnormalities (2022 - 2025)$201,478
Poor skeletal health and deformities can pose a serious risk to the expected expansion of salmonids aquaculture intooffshore and high energy farming environments which require fish with a robust skeletal system. Apart from impacting on welfare and performance offish, deformities impact on final product processing efficiency and lead to increase in downgrade. New Zealand King Salmon (NZKS) stock has beenhistorically impacted by spinal curvature deformities in their stock, and in the past two years there has been an emerging issue with intermuscularbones abnormalities (commonly referred to as pin bones). These two issues indicate poor skeletal health in some NZKS stock, and this is likely tobecome exacerbated by increased musculoskeletal challenge as seen in offshore environments. The goal of this project is to better understand pinbone development and abnormalities (and their link with spinal deformity) observed in NZKS fish as a reasonable proxy for assessing overall skeletalhealth.The project consists of five main steps, 1) a literature review of pin bone development in fish and a summary of the NZKS pin bone data in relation toharvest, production and husbandry strategies, including collation and analysis of historical records, 2) the collection and analysis of affected andunaffected pin bone samples in harvest size fish, 3) a cross-sectional exploration of pin bone development in NZKS hatchery-reared salmon coveringthe companys different production strategies 4) a study of the effect of sustained exercise on pin bone strength and 5) an epidemiologic analysis ofrisk factors for spinal curvature and pin bone abnormalities, to tease out possible associations between the two and relevant environmental, geneticand husbandry factors.
