This paper studies the impact of water temperature on the optimal management of the ration size and fish weight in off-shore farm aquaculture. A model for the expected returns of the farm is developed which includes a fish growth function influenced by fish weight, the ration size and water temperature. The output transportation cost has an ambiguous effect on the harvesting size, but the impact of water temperature is positive. These results explain empirical evidence in the Canary Islands that unfavorable economic conditions could be overcome by environmental advantageous conditions raising productivity.
