Introduction to tropical fish stock assessment - Part 2: Excercises

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 estimation of growth parameters and mortality rates, virtual population methods (including length and age based methods), gear selectivity, the yield per recruit model of Beverton and Holt, the estimation of maxim um sustainable yield using surplus production models, multispecies and multifleet problems, the assessment of migratory stocks, a discussion on the stock/recruitment relationship and the execution of demersal trawl surveys. The link between this manual and the length frequency stock assessment (LFSA) package of microcomputer programs is explained. The manual is completed with an extensive list of references (including material for further reading), a list of symbols used, a subject index and a n umber of exercises with solutions. Part 2 gives a number of exercises together with solutions. The exercises are directly related to the various chapters and sections of the manual.
