Optimization of caviar and meat production from white sturgeon (Acipenser transmontanus)
1997
Wade, E.M. | Fadel, J.G.
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 complex but is large with 10102 equations and 17905 variables. The model size allows for system stabilization and a minimization of end of model effects without artificially imposed constraints. The model demonstrates the economic feasibility of caviar and meat production as a long-term investment where break-even occurs in year 9, after the first group of caviar fish is harvested. An optimal production schedule is generated where harvest cycles from 3- and 3.5-year old fish offset caviar harvest cycles to maintain an optimal biomass on the farm. The optimal production schedule is evaluated for economical viability against a non-cyclical stable production schedule.
