Stock identification and discrimination of mulloway in Australian waters

Project number: 1986-016
Project Status:
Completed
Budget expenditure: $0.00
Principal Investigator: Patricia Dixon
Organisation: UNSW Sydney
Project start/end date: 27 Dec 1990 - 30 Dec 1990
Contact:
FRDC

Objectives

1. Investigate population structure of mulloway, Argyrosomus hololepidotus, to determine whether mulloway in Australian waters belong to one large inter-breeding population throughout their range or whether 2 or more separate stocks exist.

Summary

The population structure of mulloway throughout Australian waters was investigated with a view to providing a basis for management decisions for this recreationally and commercially important fishery. This study is limited by two factors:

1. rapid deterioration of tissue samples, affecting both allozymes and mtDNA,

and 2. small sample sizes from key sites and no samples available from Victoria.
