| Abstract |
In most multispecies fisheries there is considerable uncertainty in selection of an appropriate model to represent the dynamics of the resource. The development and application of an experimental management regime for the fisheries operating on a tropical fish community in northwestern Australia are described. The history of exploitation is summarized and a number of simple models are suggested which can mimic past changes observed in fish community composition. These models include interspecific, intraspecific, and habitat modification mechanisms. Possible socio-economic responses of the fishing industry to changes in the resource state are important to evaluation of a prospective fishing regime, and these are also modelled. The models are used to evaluate options for management of competing trap and trawl fisheries on the Northwest Shelf. |
