Waste to profit in urchin fisheries: developing business opportunities to ensure fishery sustainability and safeguard reef dependent fisheries from destructive urchin grazing

This report examines two potential applications of Longspined Sea Urchin (Centrostephanus rodgersii) via pitot scale trials; processing waste as an agricultural fertiliser and use as Southern Rock Lobster bait. The biochemical composition of Longspined Sea Urchin waste products was analysed, and the...

Rock Lobster Enhancement and Aquaculture Subprogram: the feasibility of translocating rock lobsters in Tasmania for increasing yield

Translocation involves the shifting of undersize rock lobsters to new areas to increase productivity and/or quality of product. We modelled the translocation of rock lobsters from four original sites to four release sites with a range of growth rates. Most model scenarios led to increases in...

Aquafin CRC - Atlantic Salmon Aquaculture Subprogram: environmental control of growth and early maturation in salmonids

At present the culture of Atlantic salmon within Australia produces approximately 26,000 t of fish per annum and is a direct employer of over 1100 workers with the majority of farmed fish sold nationally and only 12% exported. Environmental conditions, such as increased temperatures and high light...

Aquafin CRC - Atlantic Salmon Aquaculture Subprogram: commercial AGD and salmon health project

Prior to this project there had been investigations into some potential candidate amoebicides, with little success except for the possibility of oxidative disinfectants such as chloramine-T. This project has since tested a number of amoebicides using a progressive approach of in vitro...

Aquaculture Nutrition Subprogram: assessment of growth performance under limiting environmental conditions

This research has advanced our understanding of how fish growth is influenced by nutrition, by environment and by the interaction between nutritional and environmental factors. When the research started the majority of nutrition research considered the performance of feeds under optimum...

Ensuring monitoring and management of bycatch in Southern Rock Lobster fisheries is best practice

Bycatch is an important issue in fisheries worldwide, with the impacts of fishing activities on non-targeted species and the wider marine environment receiving increasing public attention. Issues such as the potential wastage of resources through discarding of unwanted catch, ecological impacts on...

Water use across a catchment and effects on estuarine health and productivity

This research has shown that the profitability of both agriculture on land and aquaculture in the estuary is affected by changing freshwater flows. To assess the value of water to different users across a catchment we developed a generic water accounting framework and populated it with available...

SCRC: PDRS - Seafood Molecular Biologist: Mapping Microbial Communities in Seafood Production and Processing Environments to Improve Targeting Intervention Strategies (Dr Shane Powell)

Until the 1990s, when it became possible to access and analyse DNA directly from the environment, the study of microbiology was limited to studying microbes that were able to be grown in artificial culture. The advent of DNA-based methods provided a way to access and study the enormous diversity of...
