The large yellow croaker is fish of genus yellow croaker of family Epinephelidae of order Perciformes, and is named yellow croaker, fresh food, and cucumber. The body is prolonged and flat; the otolith is slightly shield-shaped; the head and the front part of the body are rounded and the rear part of the body is comb-scaled; the lateral line is complete; the air bladder is big, and the two sides do not protrude to form side bags; the dorsal fin is continuous, and 1 deep notch is arranged between the fin thorn part and the fin strip part; the tail handle is thin, and the tail fin is wedge-shaped. The back of the body is grey yellow; each scale at the lower part of the body side always has 1 golden gland and is golden; dorsal and caudal fins are gray-yellow, the remaining fins are yellow.
In the aspect of fish feed throwing of the aquaculture industry and ship, at present, the artificial feeding is performed at fixed time every day through artificial experience, the feed throwing amount is manually set, and the feed demand of the aquaculture fish cannot be accurately estimated. The excessive feeding can lead to feed waste and water quality deterioration, and statistics show that the bait cost in aquaculture accounts for about 40% of the total aquaculture cost, so that the production value and profit of fishery are often affected due to the accumulation of the deviation of feeding amount each time. Insufficient feeding amount can influence the ingestion and growth state of fish, and the growth speed is reduced. The prior patent search also sees various intelligent feeding methods and systems for aquaculture, but related patents and researches on biological characteristics of large yellow croakers and operation conditions of farmed boats are not seen.
