Objectives

1. Use quick screening method to measure 20:5w3 and 22:6w3 fatty acids in microalgae from various Aust hatcheries.
2. Compare with existing data from standard conditions, identify features of hatchery open to be optimised.
3. Lab experiments to opt fatty acid content ...

Rock Lobster Enhancement and Aquaculture Subprogram: the nutrition of juvenile and adult lobsters to optimise survival, growth and condition

Research in FRDC RLEAS 98/303 established that tropical (Panulirus ornatus), southern (Jasus edwardsii) and western (Panulirus cygnus) rock lobsters readily consumed formulated pelleted dry feeds and exhibited a dose dependent growth response to dietary protein concentration. The derived optimum...

Increased production of juvenile Pacific oysters (Crassostrea gigas) through supplementary feeding

The standard method for growing the early stages of juvenile Pacific oysters is to hold them in systems called upwellers in land-based nurseries. Seawater is pumped through to provide the oysters with food particles. Growth rates of oysters cultured using this method were highly variable at Pipe...

Abalone Aquaculture Subprogram: optimisation of essential lipids in artificial feeds for Australian abalone

Lipids and in particular polyunsaturated fatty acids (PUFA) are important for a number of physiological functions in animals. PUFA are also major components of cellular membranes. Many marine animals cannot synthesise "essential" PUFA de novo and therefore serious deficiency signs such...

SCRC: Tackling microbial related issues in cultured shellfish via integrated molecular and water chemistry approaches

Aquacultured species such as oysters and abalone live their entire lifecycle in seawater, and co-exist with a wide range of innocuous, pathogenic and beneficial microorganisms. Some microbes cause diseases resulting in significant losses for the farms. This study set out to provide shellfish...

Seafood CRC: Commercial production of all-female reproductively sterile triploid Giant Tiger prawns (Penaeus monodon): Assessing their commercial performance in ponds.

Several Australian companies currently have breeding programs producing domesticated and selective-bred Penaeus monodon lines. The most advanced of these lines have demonstrated high commercial pond performance over several generations. However, there is a risk for the breeding program companies,...

Seafood CRC: increasing seedstock production of domesticated giant tiger prawns (Penaeus monodon) through improved male fertility

Given the rationale that pond systems are likely the most cost-effective system for large-scale production of Giant Tiger Prawn (Penaeus monodon) broodstock, this project aimed to determine whether pond-rearing poses a significant risk for broodstock production. The gross reproductive development of...
