Description

Technical Field

[0001] The utility model belongs to the technical field of fishery breeding, in particular to a long-snout catfish egg cultivation structure. Background Art

[0002] The long-snout catfish is a fish of the Catfish family and the genus Catfish. It can spawn and fertilize naturally after artificial induction of spawning. The natural hatching method has a very low fry rate and is not suitable for the needs of mass production. Generally, large quantities of fry can be obtained by artificial egg collection, fertilization and hatching. The method is: when the induced spawning effect time is expected, the female fish is checked, the female parent fish that can easily squeeze out mature eggs is lifted up, the water on the body surface is wiped dry with a towel, and then the mature eggs are squeezed into a basin. At the same time, the male fish is cut open to take out the testis, which is fully cut into pieces, diluted with physiological saline, and quickly poured into the eggs, and the sperm and eggs are stirred with goose feathers to complete the fertilization process. The fertilized eggs are then attached to a self-made square mesh and placed in a hatching pool for incubation with micro-flowing water.

[0003] During the incubation process of longnose catfish eggs, the newly hatched fry have a large yolk sac and lie on their side at the bottom of the water. They can only swing their tails but cannot swim. During this period, the longnose catfish eggs are relatively fragile. If there is no suitable opening bait and living environment, the survival rate of the fry after hatching is low. Therefore, it is necessary to design a longnose catfish egg cultivation structure to achieve water exchange with large flow and small flow rate, keep the water quality fresh, and improve the survival rate of the fry.

An L-shaped water inlet pipe 83 is provided, and a water outlet hole 84 is provided on the surface of the upper end of the L-shaped water inlet pipe 83. One end of the L-shaped water inlet pipe 83 away from the water outlet hole 84 extends to the inner cavity of the constant temperature water tank 1 and is fixedly connected to a water pump. A drain pipe 85 is provided on the top of the surface of the cultivation cylinder 81. One end of the drain pipe 85 away from the cultivation cylinder 81 extends to the inner cavity of the constant temperature water tank 1. A breathable cultivation bed 87 is welded on the top of the inner cavity of the conical barrel 82. An anti-slip ring 86 used in conjunction with the arc-shaped clamping plate 72 is welded on the top of the surface of the cultivation cylinder 81.
