Collection of fish lengths for stock assessment in developing countries

A review of the data (handling) requirements for length-based stock assessment is presented, with emphasis on the relationship between the expected outputs and the key features of the samples required, and on biases and other sources of inaccuracy

An approach to the assessment of the finfish fisheries of the Caribbean Community

This paper briefly outlines the implications of making a decision on the most appropriate alternative for carrying out stock assessments and the reasons for previous failures to conserve finfish stocks for sustainable use. The Mathews (1987) approach utilizing Age-Length Catch-Effort Keys (ALCEK) is briefly reviewed, and a suggested overall approach for the assessment of the finfish resources of the Caribbean community is outlined. With recent initiatives towards use of the precautionary approach and reference points, Carribean community countries are advised to revisit the question of the models to be utilized for the assessment of their fish stocks, paying due attention to the quantity, quality and applicability of data now being collected
