Do changes in aeration efficiency of "airwick" diffusers explain recent high mortalities during transport of live fish in bulk bins?

To provide an alternative to the use of oxygen cylinders in live transport bins, Seafood Transportation Developments (STD) initiated development of an aeration unit which could be fitted to the live bins. The system provides oxygen to the live fish by air diffusion at a high flow rate through an air...

Factors affecting the toxicity of the dinoflagellate, Gambierdiscus toxicus, and the development of ciguatera outbreaks

This project confirmed that the benthic dinoflagellate Gambierdiscus toxicus is an origin of putative ciguatoxin precursors called gambiertoxins. It was recently found in French Polynesia that gambiertoxins could be extracted from biodetritus containing wild G. toxicus and that gambiertoxins were...

Aquaculture Diet Development Subprogram - Replacement of fishmeal in diets for barramundi - improving nutritive value of alternative feedstuffs using crystalline amino acids

Australia has an abundant supply of terrestrial animal and vegetable protein feeds which has the potential to at least partly if not fully replace the fishmeal presently used in compounded aquaculture diets. A major difference between marine and terrestrial protein sources is the marked difference...

Aquaculture diet development subprogram - Dietary requirements and optimal feeding practices for Barramundi (Lates Calcarifer)

Project number: 1992-063
Project Status:
Completed
Budget expenditure: $250,109.14
Principal Investigator: Kevin C. Williams
Organisation: Department of Primary Industries (QLD)

Objectives

1. To develop feeding strategies and diets for periods of fast growth (summer) and slow growth (winter) which optimise feed conversion and growth rate
2. To determine the appropriateness of an extruded floating pellet for feeding barramundi under commercial conditions
3. To investigate the potential for sparing of fish meal in barramundi grow-out diets using synthetic amino acids and cheaper sources of supplementary protein

Summary

Feed is by far the single largest cost component of barramundi farming and accounts for about 35% of on-farm operating costs. Reducing feed costs by better tailoring dietary specifications to the nutrient requirements of the fish, by providing these nutrients at least cost and by adopting feeding practices that optimise productivity will greatly assist farm profitability. In Australia, barramundi are pond-reared over latitudes from 5°S to 22°S and this results in large seasonal variations in water temperature and consequently, in growth rate of the fish.

The research conducted in this project sought primarily to characterise the effect of water temperature on fish productivity and how modification of dietary nutrient specifications and/or feeding practices could assist in improving farming profitability. This entailed research to define the fish's response to changes in dietary supply of critical nutrients over a range of water temperatures. Research examining the efficacy of crystalline amino acids in diets for barramundi was carried out in a supplementary project (FRDC 95/69); research on the nutritive value of terrestrial feed ingredients and their suitability as replacements of fishmeal in diets for barramundi is reported in FRDC 93/120-04.

Value adding to seafood by application of modern drying techniques

There is an enormous market throughout the world for dried seafood, many of which command high prices. Six major markets have been identified by FAO. The Japanese market is very large and is growing slowly. Markets in Hong Kong and Spain, Germany, Italy are big and growing while that in Portugal is...
