Objectives

1. Assess seasonal wind, tidal & density-driven current regimes in the Gulf of Carpentaria
from the computed net water flows,
2. better understand larval prawn dispersal mechanisms from the off-shore spawning grounds to the near-shore & estuarine nursery grounds

Summary

The prawn fishing industry in the Gulf of Carpentaria is worth $100 million/year and a large proportion of this is from catches of banana prawns. In one stage of their complex life history, banana prawn larvae are carried by ocean currents from their spawning grounds to the estuarine nursery areas.

The aim of this project was to define the currents that carry the larvae so that the life history can be more fully understood and various biological hypothesis concerning the banana prawn and in particular the behaviour of larvae can be fully tested. To achieve these goals a mixture of field work and theoretical modelling and cooperation between physical oceanographers and fisheries biologists was required.

Objectives

1. Evaluate small manned submersible as observation platform when underwater observation is desirable but depths preclude normal diving activity,

Shark 'drop out rate' from hauling gill-nets in the southern shark fishery

Shark 'drop-out' is a term used by fishermen to describe the phenomenon where sharks fall out of shark gillnets during hauling operations. The term is distinguished from shark 'escapement' which is the phenomenon where sharks _struggle to free themselves from gillnets with a high probability of...

Enhancing the availability of pearl oysters for pearl cultivation in WA

The Western Australian Research Laboratories began investigating the feasibility of artificially propagating the silverlip or goldlip pearl oyster, Pinctada maxima, in 1982 and culminated its study by operating a pilot-scale, seasonal hatchery at the Broome Jetty, Broome, Western Australia from 1986...
