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...
To enhance its profitability, NPF Industry Pty Ltd needs to develop its capacity to gather key stock status data for each of its stocks so that simple bio-economic models can be developed and used to assess and potentially optimize the value of component NPF stocks. The NPF Industry Pty Ltd needs...
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...
