Abstract— The exploited fish populations and the fishery dependent on them require regular monitoring and periodical stock assessment. The resource evaluation is crucial for definition of appropriate management strategies for rational exploitation and long-term sustainable development of the exploited stocks.
The determination of the current state of a given stock is directly related to analysis of historical and present data concerning specific stock parameters which indicates the current status of the stock and suggests relevant definition of healthy exploitation levels. Such key stock parameters are growth and mortality rates, abundance indices, carrying capacity, maturity and reproduction, catch composition and recruitment [1,3,4,6,13,14].
The present article introduces a program system – MATLAB-based standalone application specifically developed to facilitate length-weight relationship of fish analysis outcome, growth and mortality parameters estimates and their confidence limits, normality tests of length-weight-frequency sample data, used in analysis. The proposed system incorporates statistical analysis of the overall significance of the mathematical models and results delivered, as well as methodology to overcome added computational errors in numerical analysis.
Keywords— fish stocks, growth and mortality parameters, MATLAB programming environment, standalone application, stock assessment.
