Evaluation of harvesting strategies for Australian fisheries at different levels of risk from economic collapse

Management of a marine renewable resource involves selecting a trade-off between conflicting objectives related to conservation and utilization. This problem is complicated by uncertainty about the current status and productivity of the resource being managed, and hence about the implications of...

Application of satellite real-time sea surface temperature data to the tuna, salmon and pilchard fisheries

This is the final report for FIRTA project 1981-056. The principal objective has been to study the application of real-time satellite-derived sea surface temperature measurements in assisting particular fisheries located in southern waters of Australia. Initially proposed for a three year period...

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.
