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.
Claims8
Method of feeding fish within the enclosure of a fish farm with enhanced visibility fish feed, said fish farm having an enclosure defined a volume having width, length, depth and a bottom, said bottom being defined by a perforated enclosure, said enhanced visibility fish feed being in the form of pellets having significantly improved visibility throughout a substantial portion of said volume of said enclosure included within said width, length, depth and bottom, relative to unenhanced visibility fish feed, said method comprising the steps of selecting said enhanced visibility fish feed in pellet form including a mica and/or titanium material thereby resulting in a substantially increased brightness and/or reflectivity relative to the brightness and/or reflectivity of said unenhanced visibility fish feed within said volume defined by said width, length, depth and bottom and distributing a quantity of said pellets including said mica and/or titanium material, of said enhanced visibility fish feed on the surface of the water in said enclosure so as to allow said fish feed to pass through said perforated enclosure if said fish feed is not eaten by said fish.
