While freshwater bathing has been used successfully to control losses, the shortage of fresh water in some salmon farming areas resulted in a quest for another treatment. Hydrogen peroxide is used overseas to control sealice infections of Atlantic salmon. Previous research suggested that it may be possible to develop a successful hydrogen peroxide treatment against AGD, reducing the reliance of the industry on fresh water. Objectives: 1. Determine effective in vitro treatment with hydrogen peroxide against Neoparamoeba perurans 2. Determine effective in vivo treatment against Amoebic Gill Disease Read moreRead less

Summary
Because Australia's rock lobster fisheries are at their maximum sustainable capacity, the value of the industry can be increased only through the development of aquaculture. In the immediate term, this could be achieved by on-growing of juveniles taken from the wild and the holding of adults for weight gain or niche marketing opportunities.

In the immediate term, this could be achieved by on-growing of juveniles taken from the wild and the holding of adults for weight gain or niche marketing opportunities. In the longer term, domestication of the specie/s and hatchery propagation of the juveniles will enable a sustainable rock lobster aquaculture industry to develop. In Australia, these opportunities are seriously constrained by the lack of a cost-effective and efficacious rock lobster feed. This contrasts with the developing industry in New Zealand where waste from the large mussel industry is an available and inexpensive source of feed. If feed comprises from 40 to 50% of rock lobster production costs as is the case for prawn and finfish grow-out operations, the availability of a suitable formulated pelleted feed is seen as a necessity for commercial production.
Preliminary feed’s development work (FRDC 98/303) for juvenile and adult lobsters has been initiated in an 18-month project that terminated in December 1999. Although all lobster species consumed the developed dry feed pellets, the productivity of juvenile animals was inferior to the feeding of fresh mussels. However, with adult J. edwardsii held in sea cages, the pelleted diets were equal to fresh mussel in maintaining the condition (moult frequency, weight increase and survival) and colour of the lobsters The sub-optimal performance of the pelleted diets for the juveniles is thought to have been due to the reduced attractiveness and /or sub-optimal nutrient specifications of the diet for the lobsters. This project will seek to develop improved and more cost-effective pelleted dry lobster feeds for P. ornatus and J. edwardsii juveniles and to improve the feeds management of adult J. edwardsii. Dietary improvements made with the juvenile work will be applied to adult lobsters being held under commercial sea cage conditions in Professor Geddes’ ‘On-growing Project’ (98/305). A collaborative research approach involving CSIRO, TAFI and UA and other agencies in the RLEAS will give the best prospects for achieving our aims. The likelihood of the project being successful is high because:
1. The initial Feed’s Development Project has shown dry pelleted diets to be well accepted by the lobsters and further improvements are likely upon implementation of the proposed targeted research. 2. The project will build on the already established strong collaborative linkages between related rock lobster research being carried out at CSIRO, QDPI, TAFI, UA and by industry. 3. The assembled project team has considerable expertise and an established track record in delivery of successful feed development for other crustaceans (prawns) and finfish, and have established strong collaborative linkages with the aquafeed industry to aid the rapid commercialisation of the research. Objectives: 1. Develop manufactured feeds for juvenile rock lobsters (ie puerulus - year 1 and beyond) that optimise survival and growth by: a) defining the chemicophysical cues that stimulate food consumption in juvenile rock lobsters, b) developing pelleted feeds that remain attractive to lobsters for periods in excess of four hours after immersion, and c) determining the optimum dietary specifications of selected nutrients required by juvenile rock lobsters for growth and development. 2. Develop manufactured feeds for adult lobsters for body maintenance and moult manipulation by a) determining the optimum pellet size and feeding frequency for maintaining the condition of adult rock lobsters and b) providing continued advice to project 98/305 on feeds development for adult lobster holding.

Summary
The need for on-going research into aquaculture nutrition and the need for continued inputs to how this research is conducted to ensure it is completed to the highest possible standard is emphasized by the fact that Australian aquaculture industries have a heavy reliance on imported nutrition technologies, feeds and ingredients for the supply of nutrients to target species. This includes feed manufacturing technologies, ingredients such as bait fish, fish meals, crustacean meals and fish oils, ....The need for on-going research into aquaculture nutrition and the need for continued inputs to how this research is conducted to ensure it is completed to the highest possible standard is emphasized by the fact that Australian aquaculture industries have a heavy reliance on imported nutrition technologies, feeds and ingredients for the supply of nutrients to target species. This includes feed manufacturing technologies, ingredients such as bait fish, fish meals, crustacean meals and fish oils, and complete feeds such as those utilised by the prawn industry. Not only does this create issues in relation to imported disease risks, continuity of supply and cost, but it means that many local products are being under utilised.
There is currently renewed interest in establishing a dedicated aquaculture nutrition research program due to the increase in cost of fishmeals and oils, their increasingly limited availability and potential contamination with antibiotic residues such as chloramphenicols if the meals are derived from some aquaculture reared products. In addition, pressure from consumers to limit the use of animal proteins in diets and limit interspecies recycling has applied new pressure to feed manufacturers and increased the need to identify and utilise alternative vegetable protein sources in aquafeeds. The increased value of the Australian dollar has also increased competition from imports and the need for the Australian sector to become increasingly efficient to remain internationally competitive with nutrition playing a key role in their capacity to achieve this. Objectives: 1. Provide expert guidance and direction for aquaculture nutrition research in Australia through maintenance of a strategic plan, provision of technical review services and inputs into project development. 2. Identify nutrition research priorities that are not being addressed through existing portfolios and initiate research projects in this area. 3. Promote capacity building and human capital development through the provision of training and resources in aquaculture nutrition and aquafeed manufacturing. 4. Develop risk management strategies as required for various aquaculture sectors in relation to nutrition to assist the research priority setting process. 5. Improve communication of nutrition research outcomes and current nutrition research between scientists, aquaculturalists, ingredient suppliers and feed manufacturers utilizing workshops, planning meetings and conferences.

There are several reasons that targeted research on the variable cost of fishing is warranted as part of the bioeconomic activities of the theme. First, some fisheries regulations have evolved over long periods with lower fishing costs, a revision of these could increase the profitability of the fishery and may be necessary to ensure economic viability into the future.

First, some fisheries regulations have evolved over long periods with lower fishing costs, a revision of these could increase the profitability of the fishery and may be necessary to ensure economic viability into the future. Secondly, fuel is one of the largest variable cost factors in most fisheries and has proven to be highly volatile in price over the last few years; extensive evidence suggests that fuel prices will continue to rise at rates significantly faster than most other costs. Third, the economic flows from fuel consumption tend to provide a lower contribution to GDP than other variable costs such as labour (due to the export nature of the cost); consequently disproportionate increases in fuel prices may result in a lower fishery contribution to GDP.Read moreRead less
