Predicting the impacts of shifting recreational fishing effort towards inshore species

The project outputs have led to the following outcomes: 1. A model has been developed enabling reliable estimation of mortality of fish species that undertake size-related, unidirectional, offshore movements from age and length data. This new modelling approach is likely to be applicable to stocks...

Summary

Both the King George whiting and the Black bream are important commercial and recreational finfish species in south-western Australia. The fisheries for Black bream are restricted to estuaries, whereas the King George whiting recreational fisheries is based in both estuaries and protected marine waters. Due to the increase in catches of King George whiting and Black bream, the Western Australian Fisheries Department required research to develop management policies that will benefit both the commercial and recreational fishers who target these two species. The main biological information needed was the growth rate, maximum age, age and length at sexual maturity, spawning period and location, habitat requirements and the selectivity of gill net meshes for these species in south-western Australia.

Estimation of natural and fishing mortality using length composition data

The objectives of this project were to develop length-based approaches for estimation of natural, fishing and total mortality, and to explore the application of these methods to the data from selected fisheries. The methods that were developed were essentially length-based versions of age-based...

Golden fish: evaluating and optimising the biological, social and economic returns of small-scale fisheries

This project investigates recreational and commercial fisher motivations for using a fishery and the beliefs, attitudes and perceived benefits of aquaculture-based enhancement programs and other management options. It also determines the total economic value for recreational fishing for Blue Swimmer...
