Salmon farms are quite different from terrestrial farms in providing both nutrition and calories. They produce stunningly more of both than their land-based counterparts.
Focused on land-use implications of terrestrial meat production, the study concluded that aquaculture can meet the protein demands of a growing global population without adding strain on arable land, water or our other natural resources.
Wisconsin State Rep. Mary Felzkowski and others are championing aquaculture to grow food production in the state, with a keen interest in recirculating aquaculture systems (RAS).
In integrated multi-trophic aquaculture, farmers combine the cultivation of fed species such as finfish or shrimp with extractive seaweeds, aquatic plants and shellfish and other invertebrates that recapture organic and inorganic particulate nutrients for their growth.
