Solar heat energizes Ontario fish farms

摘要

rchard Moccia, coordinaor of (he Alma Aquaculure Research Station in Ontario is spear heading an evaluation of a new solar water heating system as a cost-effective way to diversify and increase fish production. "Ontario fish farmers are constrained by the province's cool water temperatures," says Moccia. "But we're hoping that solar heating can solve some of the problems by taking two or three months off a species' growth time, allowing Ontario farmers to be more competitive with the United States." American companies that collect their water from warmer sources can choose to farm a greater variety of species and enjoy higher production rates and larger profits since the fish can be sent to market sooner.
