The aim of this study is to examine the relationship between the total length and standard lengths with live weight of the freshwater pikeperch growing in the Beyşehir Lake population using four mathematical models. For this, 50 female fish materials of marketable size limit age were used. The data obtained were divided into two groups as estimation (70%) and test (30%) data. The applied models are exponential decay, exponential and Wood models, as well as in such researches generally preferred power model. R2, R2adj, RMSE, AIC, BIC and MAPE values were used as goodness of fit tests and comparison criteria of the models. According to the study results, total length gives more accurate estimates than standard length in estimation of live weight. As a result, it was concluded that other models may give better results than the power model, and they were suggested to be used in estimating the live weight of pikeperch fish.
