Sažetak
We consider an exploitable model of a pisciculture in a fish-pond considering the damage caused by a cormorant which is the following:
dy
= cy (1 y/A) H(y) H0, c> 0,
dt
where y(t) is a qantity of fish in the moment t, H(y) quantity of harvesting, and H0 constant damage caused by cormorants.A non-harvesting model (H(y) = 0) is specijally considered when the fish weight is up to 500 g beacause in that period the damage caused by cormorants is the biggest.Model stationarity, optimal harvesting strategy and the maximum yield as well as the optimal parameters estimation problem will be analysed.The model will be tested by using empirical data obtained in the fish-pond D.
