Objectives

1. To describe factors which determine the carrying capacity of juvenile nursery habitats for tiger prawns (Penaeus esculantus and P semisulcatus)
2. To describe factors which limit the distribution of seagrass species that form important nursery habitats for juvenile tiger prawns
3. Examine the distribution and abundance of juvenile banana prawns (P. merguiensis) in different mangrove communities.
4. To classify mangrove communities and describe the productivity of different communities

Northern pelagic fish stock research

In 1982, CSIRO applied to the Fishing Industry Research Trust Account for funding of a joint biological investigation of northern Australian pelagic fish stocks. At that time these stocks supported a Taiwanese surface gill-net fishery based on sharks, tunas and Spanish mackerel. During the 1970's...

Development and use of the egg production method to assess the biomass of orange roughy off eastern Tas

Orange roughy is one of Australia's most valuable finfish However, its aggregating behaviour during spawning, slow growth, and longevity render it vulnerable to over-exploitation. Some stocks in New Zealand are at extremely low levels after only ten years of exploitation. Good management is vital...

A comparison of otolith microchemistry and genetic techniques for evaluation of stock structure of the jackass morwong Nemadactylus macropterus

Four different techniques for determining the stock structure of a marine fish species were compared, using as a subject the jackass morwong. The four techniques examined were allozyme analysis, mitochondrial DNA analysis and two techniques based on measuring the composition of otoliths ('ear...

Causes of decline in stocks of commercially important prawns in the Northern Prawn Fishery

The following report is a description of the two FIRTA projects (85/85 & 89/13) which examined recruitment processes in penaeids at Albatross Bay in the northeastern Gulf of Carpentaria over the years 1985 to 1992. The aim of the first of the two projects was to identify the main factors which...
