Fish growth acceleration and density-increasing apparatus and method

摘要

This disclosure is concerned with novel, submersible cover designs for pools containing fish, such as salmonoids and the like, including vertically separated and stacked light-opaque covers that divide the pool into dark zones in which the fish are trained to rest in stacked formation with accelerated feeding habits and with a plurality of openings in the covers to provide a plurality of feed regions along the surfaces of the covers.
