The western pacific waters, which are spread widely between the north sea-road to the philippines in japan, are mainly distributed in vietnam, philippines, taiwan, mainland china, the korean peninsula and the japanese lissenia (except in some northern regions). Japanese eel is a small and medium sized fish. The body length is 300-450 mm, and the weight is 250-500 g. The maximum individual body length can reach 1.3 meters. The body is slender, the front part is nearly cylindrical, the back part is flat, the head tip and the mouth part are flat, the eye is positioned at the front part of the head, the mouth is large, the two jaws and the plough bone are both provided with fine teeth, and the gill hole is positioned in front of the base part of the pectoral fin. Small scale, buried under the skin, and mucus on the body. The dorsal fin and the hip fin are long and low, are connected with the tail fin and have no ventral fin. Dark green on the upper part of the body and grey white on the abdomen. Is a high-grade edible fish, has tender meat quality and good taste, and is rich in protein and fat. 5-6 thousand tails/kg of Japanese eel, 5.75cm of average body length and 0.4g of average body weight. The back of the body is gray black to yellow brown, and the abdomen is white without any stripes. The white young Japanese eels appear from late 3 months to the end of 4 months and are generally captured at the junctures of coastal waters and brackish waters in China. The Japanese eel has a black ring at the tail end, is slender, has small eyes and mouth, has a sharp snout end, the distance from the snout end to the anus accounts for 39 percent of the body length, the distance from the anus to the tail end of the tail fin accounts for 61 percent of the body length, a longitudinal groove is arranged on the main upper jaw bone, and the trunk accounts for 26.9 percent of the body length.
Japanese eel young eel all can adopt powdery compound feed to feed, and powdery compound feed processingequipment need carry out twice filter procedure to it when actual production, but on the material that produces after current powdery compound feed processingequipment filters can keep the filtration for a long time, inconvenient clearance influences actual filter effect, and simultaneously, blocking phenomenon appears easily in the filtration, is unfavorable for continuous production, and in addition, current powdery compound feed all is wholeness, has not produced powdery compound feed to young eel.
