PURPOSE:To uniformly and efficiently supply a large amount of a feed to a wide range with saved labor in a short time, by supplying feed in an amount of several days to a cold reserving chamber of a feeder for farming fishery provided in the distant offing, pulverizing and storing the feed in a dispersed state and jetting the resultant dispersion through a pump into crawls with a water discharge gun. CONSTITUTION:A feeder 1 for farming fishery is constituted for supplying a feed in a required amount from a cold reserving chamber 2 having a refrigerator 8 capable of freezing and preserving the feed in an amount of 3-7 days into a pulverizer 3 at intervals of a given time, pulverizing and supplying the feed to a water storage tank 4, thawing the feed at water temperature, storing the thawed feed in a state of a dispersion in water, boosting the dispersion to 2-3atm. by a pump and discharging the dispersion with a water discharge gun 6. The feeder 1 is then floated on, e.g. a given surface 9 of the sea near many crawls 7 provided in the distant offing of sea or lake or near the shore through buoys 10, and a frozen feed, such as moist pellets, prepared by mixing live baits, e.g. sardine, with an artificial feed is supplied once every 3-7 days, pulverized, thawed and kept in the dispersed state in the same manner as described above to supply the feed to the crawls 7, e.g. at a distance of 12m at the maximum with the water discharge gun 6.
