| Abstract: | A bioeconomic model of fish growth in recirculating aquaculture systems was constructed by developing a bioenergetic model comprised of metabolic sub-models for growth, ammonia production, and oxygen consumption. Metabolite accumulations are determined by exogenous control variables
for filtration and aeration and used to indirectly represent management ability.
Numerical solutions to model parameters were obtained using a two point boundary shooting algorithm within a dynamic profit maximization framework. Optimal trajectory, isoquant, and bioeconomic optimization analyses describe specific tradeoff relationships existing between nutrition, density, and technology. Results demonstrate the economic importance of these relationships changes over time in response to fish weight, and not always in ways
suggested by the physical importance of individual factors. Specifically, economically viable tradeoffs between dietary protein and stocking density occur
over relatively narrow regions of management ability. Without highly experienced
and capable management, the biological realities of recirculating systems
may preclude profitable system operation. |
