Abstract
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.
Claims49
Apparatus for accelerating the growth of fish, including salmonoids and the like, within a pool of water containing the fish, comprising light-opaque cover means provided with means supporting the same submerged within the pool;
- the cover means having a plurality of open regions spaced along its surface intermediate light-opaque regions of the cover means;
- said light-opaque regions producing dark light-shielded zones within the pool underneath the same for the fish to rest in quiet, with said open regions providing access to and visibility for feed immediately thereunder;
- and means for promoting visual feeding by the fish under said open regions.
Apparatus for accelerating the growth of fish, including salmonoids and the like, within a pool of water containing the fish, comprising a plurality of vertically spaced and stacked cover means of light-opaque material disposed within the pool and defining dark zones under each of the same for the fish to rest in quiet;
- light-transmitting regions of the pool not opaquely covered by the cover means;
- and means for promoting visual feeding by the fish in said light-transmitting regions.
A method of accelerating the growth of fish including salmonoids and the like, that comprises, stocking a pool of water with fish;
- circulating the water around the pool with feed;
- dividing the pool into a plurality of vertically spaced zones;
- blocking light impinging upon the pool from entering each of said zones to render the zones dark superposed rest areas wherein the fish rest in dense stacks;
- and transmitting light at predetermined unblocked regions of the pool to expose the feed in the water thereat to fish resting in said dark zones and able to view unblocked light-illuminated feed regions.
A method of accelerating the growth of fish including salmonoids and the like, that comprises, stocking a pool of water with fish;
- circulating the water around the pool with feed;
- submerging a light-blocking cover in the pool while providing a plurality of openings in the cover at a plurality of locations along the surface of the cover;
- and holding the cover in submerged position to provide dark zones under the light-blocking portions of the cover in which the fish may rest in stacks and view the feed in the regions under the said openings in the cover.
A method of promoting fish growth that comprises densely populating a first pool with fish, the first pool comprising a volume of water contained within boundaries, circulating water through the first pool with feed, providing the pool with a light-blocking cover means forming thereunder at least one dark zone shielded from light, in which zone the fish can rest in darkness, illuminating a region of the first pool outside of the dark zone but laterally visible to the fish resting therein for enabling the fish to feed in said illuminated region, maintaining the fish in said first pool for a continued growth period sufficient to train the fish to adapt to the foregoing resting and feeding conditions, and thereafter transferring the fish to a second pool of water, as for maturation purposes and the like, said second pool being provided with light-blocking cover means forming thereunder at least one dark zone in like manner to the first pool, and allowing the fish to grow in the second pool in continuation of said foregoing conditions.
