OPTIMIZATION OF CAVIAR AND MEAT PRODUCTION FROM WHITE STURGEON (ACIPENSER-TRANSMONTANUS)

A multi-period mixed integer linear programming model was developed to optimize caviar and meat production from a white sturgeon production facility over a 51 year time horizon. The model is only moderately com plex but is large with 10 102 equations and 17 905 variables, The mode l size allows for system stabilization and a minimization of end of mo del effects without artificially imposed constraints. The model demons trates the economic feasibility of caviar and meat production as a lon g-term investment where break-even occurs in year 9, after the first g roup of caviar fish is harvested. An optimal production schedule is ge nerated where harvest cycles from 3- and 3.5-year old fish offset cavi ar harvest cycles to maintain art optimal biomass on the farm. The opt imal production schedule is evaluated for economical viability against a non-cyclical stable production schedule. (C) 1997 Published by Else vier Science Ltd.
