Turnitin: A Decision Support System for Estimating Growth Parameters of Commercial Fish Stock in Fisheries Industries
Abstract
In this paper we present a Decision Support System (DSS) to estimate the values of the growth parameters from the yield effort data of a harvested population. The software is developed using Visual C# programming language in windows form application. Several softwares are used to check the validity of the multiple linear regression computational output in the DSS. The multiple linear regression computation is done using Ordinary Least Square (OLS) method and its computation comes from the discretization of two most known growth models, namely Logistic growth model and Gompertz growth model. We discretize the models in terms of yield effort variables and used the resulting equations as the bases for computing the intrinsic growth rate r and the carrying capacity K parameters which are the main ingredients in the MSY formula. Those models are also used as two selection tools placed in the main menu of the software. We use an existing published data as an example to estimate the growth parameters. We also compute the Maximum Sustainable Yield (MSY) for each model which represents the maximum amount of allowable biomass extracted from the fish population without harming the sustainability of the fisheries. Technically it suggests the value of the maximum sustainable yield as a decision to the harvester in managing the population and is often represented in a function of the growth parameters of the harvested population. Knowing the right growth parameters of the population is critical in determining the MSY, since the MSY is not stable. Hence, using an inaccurate values of growth parameters is likely detrimental in applying the MSY to the real fisheries. Our DSS has a contribution as a tool in reducing the error in calculating the growth parameters and the MSY. We found that the results are in agreement with the known literatures.
