Book Description
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 references, 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.

Book Description
In Part I a selection of methods on fish stock assessment is described in detail, with examples of calculations. Special emphasis is placed on methods applicable to tropical fisheries, i.e. those based on the analysis of length frequencies. After a short introduction to statistics, it covers the estimatation of growth parameters and mortality rates, virtual popualtion methods (including length and age-based methods), gear selectivity, the yield per recruit model of Beverton and Holt, the estimation of maximum sustainable yield using surplus production models, multispecies and multifleet problems, the asssessment of migratory stocks, a discussion on the stock-recruitment relationships and the execution of demersal trawl surveys. In Part 2, a number of exercises with worked out solutions is given. The exercises are directly related to the various chapters and sections of the manual.

Some Simple Methods for the Assessment of Tropical Fish Stocks
Author: Daniel Pauly
Publisher: Food & Agriculture Org.
ISBN: 9789251013335
Category : Pets
Languages : en
Pages : 72
Book Description
This selection of methods is based on lecture notes used at a FAO/DANIDA training course held in Mombasa, Kenya, in May-June 1980. The methods presented are: regression and correlation, estimation of growth parameters from length-frequency data, estimation of mortalities (total, natural, fishing mortality) and analysis of catch and effort data. A brief annotated bibliography of tropical fish stock assessment is included.
