International Workshop on ciguatera management

An International Workshop on Ciguatera Management was held at QDPI's Joondoburri Conference Centre on Bribie Island, 13-16 April 1993. This meeting provided the first opportunity for discussion of issues related to ciguatera at an international forum in Australia. Fifty-six registrants participated...

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)
Project start/end date: 11 Oct 1992 - 17 Nov 1999

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.

Development of post-harvest handling technologies for the under-utilised cross-jurisdictional Royal Red Prawn fishery

The research team have studied the supply chain of Royal Red Prawns including the fishing operations, prawn handling and processing, and current market supply chains. The research team has also undertaken extensive sensory investigation to understand the specific sensory qualities of the Royal Red...
