The current status of lobster culture research is presented in an economic context by describing culture cost projections and their sensitivity to parameter variation. The current state of the mathematical model is described and related to recent research results. Examples of culture costs with heat recovery, thermal effluent, warmer ambient temperatures and complete recirculation as alternatives to fossil fuel heating are presented. Sensitivity analysis reveals two important areas of research: 1) development of artificial foods with higher growth rates and description of their impact on metabolism, and 2) description of excretion rates and tolerances of ammonia. Economic feasibility of communal rearing is evaluated and economically more attractive approaches suggested. The impacts of increased growth rate due to genetic selection and eyestalk ablation on culture costs are presented. Results show that the maximum cost savings due to increased growth rate when metabolic rate is increased by the same factor is 25% of total culture costs.
