Determination of the biological parameters required for managing the fisheries of four tuskfish species and western yellowfin bream

Data have been collected on the biology of western yellowfin bream and four tuskfish species that are of the type and quality required by managers for developing appropriate plans for conserving the stocks of these five commercial and recreational species. Emphasis was thus placed on determining (1)...

Objectives

1. Determine the age and size composition and growth of Dhufish.
2. Determine the location and period of spawning of Dhufish.
3. Determine the habitats occupied by Dhufish and whether these change with size and maturity.
4. Determine the age and size at which sexual maturity is attained.
5. Determine the fecundity of Dhufish and whether this species spawns more than once in a breeding season.

Development of an ecosystem approach to the monitoring and management of Western Australian fisheries

Diversity and ecosystem-based indicators were calculated for commercial finfish fisheries from 1976 to 2005 for the West Coast, South Coast, Gascoyne, Pilbara and Kimberley bioregions. The ecosystem-based indices, which detect changes in the species composition of the food web within the ecosystem,...

Determining biological characteristics of the champagne crab (Hypothalassia armata) for management purposes

During recent years, commercial trap fisheries have developed for the champagne and crystal crabs in deep waters off the lower west and south coasts of Western Australia. Thus, data on crucial aspects of the biology of these species were required to enable plans to be developed for conserving their...
