Abstract: Several portfolio selection models for fishery management are presented. The financial risk is measured by the first lower partial moment of the return. The purpose of the models is to obtain optimal fishing plans that minimize the financial risk or maximize the expected return. The ranges of variation for the parameters of the minimum risk model are determined. A numerical example for a fishery from the Galati county, Romania is analyzed.

Keywords: portfolio selection, fishery management, lower partial moment, risk, maximum sustainable yield, risk.
