  • Patent number: 6669970
    Abstract: An enhanced fish feed and a method of feeding fish with the enhanced feed are described for particular use in fish farms. The fish feed comprises pellets which are coated with a material intended to contrast highly with conditions within cages of the fish farm and thereby become visible to fish below the surface and humans near the surface. A coating of white material, preferably a mica/titanium dioxide compound, is appropriate. The enhanced visibility of the feed increases the water feeding volume within the enclosure. This reduces fish congestion and stress upon the fish during the feeding period and increases feeding rate.
    Type: Grant

    Abstract: An enhanced fish feed and a method of feeding fish with the enhanced feed are described for particular use in fish farms. The fish feed comprises pellets which are coated with a material intended to contrast highly with conditions within cages of the fish farm and thereby become visible to fish at lower levels and humans near the surface. A coating of white material, conveniently a mica/titanium dioxide compound, is appropriate. The enhanced visibility of the feed increases the water feeding volume within the enclosure. This reduces fish congestion and stress upon the fish during the feeding period and increases feeding rate.
