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...

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...

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)...
