    Abstract

    Production models form one of the two groups of models used in studying fish population and assessing the state of the fish stocks. Unlike the analytical models, they do not consider the events within a population, and particularly ignore the growth and mortality of the individuals forming the population. These models view population as one unit of biomass, with all individuals having the same growth and mortality rates. The surplus production models deal with the entire stock, the entire fishing effort and the total yield obtained from the stock, without entering into any details such as the growth and mortality parameters or the effect of the mesh size on the age of fish capture etc. Surplus production models were introduced by Graham (1935), but they are often referred to as Schaefer-models.
