Description
Technical Field
The invention relates to the technical field of large yellow croaker culture, in particular to a three-dimensional culture method of large yellow croakers.
Background
The large yellow croaker is fish of genus Pseudosciaenae of family Botrychidae. The body is elongated and flat, and a plurality of rows of luminous particles are arranged on the body side and the abdominal surface; the head is blunt and sharp. The cleft mouth is large, the end position is inclined, the kisses are not protruded, the length of the upper jaw is equal to that of the lower jaw, and the rear edge of the upper jaw reaches the rear edge of the eye socket; the inner row teeth of the mandible teeth are larger, and the outer row teeth are tightly attached to the inner row teeth; 4 or 6 chin holes, 4 holes in the center are arranged around the Yisut, and the front 2 holes are small. The number of the nostrils is 2, and the long round back nostril is larger than the round front nostril. The inferior border of the orbit extends to the level of the top of the anterior maxilla. The rear edge of the front gill cover is provided with sawteeth, and the gill cover is provided with 2 flat spines. The head is scaled by the circle except the top and the back of the head, and the front 1/3 of the body is scaled by the circle and the rest is scaled by the bar; the scales are smaller. The otolith is yellow croaker type, i.e. shield shape. The starting point of the ventral fin base is behind the vertical line of the upper edge point of the pectoral fin base; the tail fin is wedge-shaped. The front part of the swim bladder is round, and does not protrude into a side sac, and the rear end of the swim bladder is sharp; each side branch has an abdominal branch and a dorsal branch, the dorsal branch is spread in the form of a wing, and the abdominal branch is divided into an upper branch and a lower branch. The upper half of the body is yellow brown, and the lower half has golden yellow glands under each scale. Dorsal fin is light yellow brown; the tail fin is light yellow brown, and the tail edge is black brown; the buttocks, abdomen and pectoral fin are bright yellow. White in the mouth and reddish in the margin. The upper part of the gill cavity is black, and the lower part is pink. Mainly inhabit coastal and coastal sand and mud bottom water areas, mostly inhabit middle bottom water areas, and enter river mouth areas. The body is dull, prefers turbid water, and mostly floats upwards in dawn, dusk or heavy tide, and descends to the bottom layer in daytime or small tide. Mainly play the role of eating crustaceans such as small fish, shrimps, crabs and the like. The swim bladder can sound and can make a 'pyrrole' sound in the reproductive stage; when the fish school is dense, the sound is like water boiling sound or billow sound; when the reproductive season comes, the clusters will migrate to the near river mouth or island or shallow water area near the bank of the gulf.
