Historically, stock assessments of Atlantic blue marlin (Makaira nigricans) and white marlin (Tetrapturus albidus), conducted under the auspices of the International Commission for the Conservation of Atlantic Tunas (ICCAT), have been restricted to production modeling approaches. Production models are used due to the unique fisheries and biological aspects of the species which result in a pauci...

• A web-based tool collating freely available stock assessment packages. Packages divided into 10 classes. evaluated whether state-of-the-art within class. Full specifications provided in a consistent manner. Test data and instructions for some Stock assessments are integral to fisheries management, the demand based on population dynamics models continues increase. Historically, have been bespo...

A new feature extraction method for very non-normal data: analysis of multivariate species-size data from a tuna purse-seine fishery .. This report is organized into sections corresponding to the topics discussed at the workshop. Under each section, introductory text, taken from the background information provided to participants before the workshop, is given. Then abstracts for each presentati...

We consider a Monte Carlo Markov chain (MCMC) algorithm for fisheries stock assessment. The biomass of this stock at a given year could be modeled as a nonlinear function of the biomass and catch for the two previous years, of different parameters (recruitment, growth rate, natural mortality rate). Given a time series of annual catch and effort data, we would like to achieve the best fitting be...
