Process and apparatus for fish growth acceleration

摘要

This disclosure is concerned with novel cover arrangements for providing dark stacking and rest areas in confined water volumes for fish growth acceleration, including salmonoids and the like, and involving pluralities of closely spaced covers contacting the water and providing successive dark areas while influencing water circulation by the edges of the covers to swirl feed thereat; forms of these arrangements being adapted both for land-constructed pools or ponds, and confined effective pool or pond volumes in the sea constructed as netted sea cages bordered by floating or exposed walkways and the like.
