A collaborative investigation on the usage and stock assessment of bait fishes in southern and eastern Australian waters, with special reference to pilchards (Sardinops sagax neopilchardus)

This project was initiated in response to a rapid increase in the demand for pilchards and other baitfish species and the subsequent expansion of purse-seine fisheries throughout southeastern Australia. During the course of the proj ect, the need for research on pilchard stocks was further increased...

A data management and reporting system and temporal and spatial analysis of historical catch records in the SA abalone fishery

Abalone stocks exist as a large number of metapopulations or sub-stocks each with peculiar growth and mortality characteristics. Hence different populations respond differently to exploitation through fishing. The sustainability of this fishery is linked to effective management of these...

Spawning biomass of Jack Mackerel (Trachurus declivis) in the East sub-area of the Small Pelagic Fishery during summer 2019

Estimates of spawning biomass obtained using the Daily Egg Production Method (DEPM) are the primary biological performance indicator for quota species in the Small Pelagic Fishery (SPF). The objective of this study was to conduct ichthyoplankton and adult trawl surveys that underpin the DEPM in the...

Seafood CRC: optimising business structures and fisheries management systems for key fisheries

There is currently an estimated economic gap (lost profit) in the CRC participant fisheries of approximately 40% or $200 million per annum.. If the economic gap could be halved from 40% to 20% the profitability of CRC fisheries would be improved by approximately $100 million. This project aimed to...

Summary

In July 1993, a program was initiated by the South Australian Research and Development Institute (SARDI) and the South Australian Rock Lobster Research Association (SARLRA) to study the population dynamics of the Southern Rock Lobster.  The study fitted with, and became part of, the tri-state strategic research direction for Southern Rock Lobster.  The program is intended to provide a scientific basis for management of the fishery and reflected concerns of potential over-exploitation in the face of increasing fishing effort and fishing power.  The program includes data collection and analysis at the recruit level as well as modelling of populations and catch forecasting.   Requirements for such analyses include spatial and temporal data on growth, recruitment, and fecundity.  
 
This report details the first part of a study aimed at enhancing the resolution of such data by establishing a field condition index for the Southern Rock Lobster.  The work also included the establishment of a system for moult staging in this species.  The condition assessment methods tested here include tissue RNA DNA ratios, lipid and protein content.

Seafood CRC: bioeconomic decision support tools for Southern Rock Lobster

The Southern Rocklobster fishery is the most developed of the fisheries included in this series of projects because sophisticated bioeconomic models and stock projection capacity had already been advanced through previous research. This research takes the process further to extend the modelling...
