Synopsis (short abstract) This manual starts with an introduction to the mathematical models applied in fish stock assessment. The basic assumptions about a model and the concepts of variation rates of a characteristic in relation to time are presented. The concept of cohort and models for the individual growth of the cohort are developed. In the chapter concerning the study of the stock, the fishing pattern and its components are defined, the most used models for the stock-recruitment relation are presented, as well as the short- and long-term projections of a stock. With regard to fishing resources management, the discussion is focused on the biological reference points. Finally, the general methods of estimating parameters are described, with special relevance to the cohort analysis by age and length. Then a solution of the exercises from the last course held in IPIMAR, is presented by the author and the scientist Manuela Azevedo.

    BAYES-SA - Bayesian stock assessment methods in fisheries - User's manual 2001

    Bayesian approaches to stock assessment provide a means for the analyst to combine information for the stock for which an assessment is needed, information based on expert opinion, and inferences for other species in a probabilistic framework. It is even possible to consider uncertainty about which model of the population dynamics is correct. This manual provides an overview of the application of Bayesian methods through a series of worked examples in EXCEL. The examples are based on biomass dyn amics and stock-recruitment models, and focus on the use of assessments that form the basis for evaluating the consequences of alternative management actions.

    Introduction to tropical fish stock assessment - Part 1: Manual (French version not published) 1998
    Also available in:
    In Part 1, Manual, a selection of methods on fish stock assessment is described in detail, with examples of calculations. Special emphasis is placed on methods based on the analysis of length-frequencies. After a short introduction to statistics, it covers the estimation of growth parameters and mortality rates, virtual population methods, including age-based and length-based cohort analysis, gear selectivity, sampling, prediction models, including Beverton and Holt's yield per recruit model and Thompson and Bell's model, surplus production models, multispecies and multifleet problems, the assessment of migratory stocks, a discussion on stock/recruitment relationships and demersal trawl surveys, including the swept-area method. The manual is completed with a review of stock assessment, where an indication is given of methods to be applied at different levels of availability of input data, a review of relevant computer programs produced by or in cooperation with FAO, and a list of refer ences, including material for further reading. In Part 2, Exercises, a number of exercises is given with solutions. The exercises are directly related to the various chapters and sections of the manual.
