摘要
Year-round production of hybrid striped bass fingerlings has been limited by low survival in ponds during late summer. A whole-farm model was developed to assess economic effects of incorporating indoor tank production and mobile nursery systems to extend the fingerling production season. Mixed-integer linear programming models were constructed for six production scales with three sizes of ponds and indoor tanks and with a mobile fish nursery system. Optimal allocation of production activities was sensitive to varying survival rates of fingerlings and monthly sales patterns. Breakeven prices in winter production of hybrid striped bass fingerlings in indoor tanks were 3-4 times higher than in other months, implying that year-round production would require hybrid striped bass fingerling growers to receive higher prices to cover costs of production in winter months.
