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

Abstract

The levels of commercial and recreational exploitation of the fish stocks of certain species in the ecologically very important environment of Shark Bay, Western Australia, are high and continuing to increase. However, the amount of biological data that can be used for management purposes for most of those species is minimal. The ability to sustain stocks of such species, in the face of increasing fishing pressure, by setting in place appropriate management plans is dependent on acquiring strategic information on the biology of those species
