Culture equipment and method capable of increasing survival rate of miichthys miiuy

Abstract

The invention discloses culture equipment and method capable of increasing the survival rate of miichthys miiuy in the technical field of fish culture. The equipment comprises a box body assembly including a culture box and a screening box, a float maintenance assembly and a screening assembly, wherein a wave sensor is arranged on a bracket, and the screening assembly is arranged between the culture box and the screening box; through the float maintenance assembly, when fish shoal fighting occurs, the wave sensor senses the change of water surface waves, wave type water waves are generated inthe water body of the culture box, and the effect of dispelling a fish shoal is achieved; the miichthys miiuy with different sizes in the culture box is screened into the screening box regularly through the screening assembly, and the situation that big miichthys miiuy eats small miichthys miiuy due to the serious inconsistent miichthys miiuy size is avoided; and a dredging rod is driven to reciprocate at a screening opening through a dredging assembly under the action of circulating water flow, the miichthys miiuy with the larger size is pushed away, the screening efficiency is improved, theblockage problem is avoided, and the survival rate of miichthys miiuy culture is increased.

Description

technical field [0001] The invention relates to the technical field of fish breeding, in particular to a breeding equipment and method capable of improving the survival rate of squid. Background technique [0002] The body of the catfish is elongated and flat on the sides, the back and abdomen are shallow arcs, the general body length is 45-55 cm, the weight is 500-1000 grams, and the large individual can reach more than 10 kg, the mouth is large and slightly inclined, the body is covered with ctenoid scales, and the scales are small , the surface is rough, the head is covered with round scales, 4 jaw holes, the central jaw hole and the inner jaw hole are arranged in a square, without barbels. The outer teeth of the upper jaw and the inner teeth of the lower jaw are enlarged, showing canine shape, and the small teeth on the inner surface are grouped in bands, the eye circles are large, and the eye membranes are highly transparent and bright red. The body is blue-gray brown,...

Problems solved by technology

[0003] When the squid is bred, the squid is lively by nature, and there are often problems of different growths in the same breeding box. After a long time without treatment, the polarization of the fish population becomes more and more serious, and the problem of big fish eating small fish appears. The shoals tend to flock and fight in the breeding tank, resulting in the death of the scorpion and the decrease of the survival rate. For this reason, we propose a breeding equipment and method that can improve the survival rate of the scorpion
