Problems solved by technology

However, due to the unevenness of the feed, the price is rising year by year, the cost of breeding is increasing, and the income of farming is getting lower and lower. The development of yellow catfish farming has encountered a bottleneck, and industry competition has led to little profit left.
Moreover, the existing farming model has brought negative impacts on ecological and environmental benefits, especially the eutrophication of water bodies, the serious accumulation of sludge in ponds, and aggravated pollution

Embodiment 1

[0014] A three-dimensional culture method for improving the breeding efficiency of yellow catfish, adopts the three-dimensional culture mode of yellow catfish-olive razor clam, mainly cultures the yellow catfish, and breeds olive razor clam; its preferred scheme is:

[0015] The fish and mussel polyculture method comprises:

[0016] S1: Drain the sewage from the breeding pond, and evenly apply slow-release fertilizers after excavation and plowing. The depth of excavation and plowing is 14 cm, and the amount of fertilizer applied is 140 kg / mu. The preparation method of the slow-release fertilizers includes the following steps : Weigh walnut shells, sawdust, corn stalks, and rice stalks sequentially according to the mass ratio of 6:5:4:3, grind them to a range of 2-3 mm, heat up to 300°C and carbonize for 20 minutes to obtain charcoal powder. The bone powder is mixed according to the mass ratio of 9:2, and 3 times the volume of urea aqueous solution with a mass concentration of ...

Embodiment 2

[0021] A three-dimensional culture method for improving the breeding efficiency of yellow catfish, adopts the three-dimensional culture mode of yellow catfish-olive razor clam, mainly cultures the yellow catfish, and breeds olive razor clam; its preferred scheme is:

[0022] The fish and mussel polyculture method comprises:

[0023] S1: Drain the sewage from the breeding pond, and evenly apply slow-release fertilizers after excavation and plowing. The depth of excavation and plowing is 16 cm, and the amount of fertilization is 145 kg / mu. The preparation method of the slow-release fertilizers includes the following steps : According to the mass ratio of 6:5:4:3, walnut shells, sawdust, corn stalks, and rice stalks were weighed successively, crushed to a range of 2-3 mm, heated to 310°C and carbonized for 25 minutes to obtain charcoal powder, which was mixed with animal The bone meal is mixed according to the mass ratio of 9.5:2.5, and 3.5 times the volume of urea aqueous solution...

Abstract

The invention relates to the technical field of modern agricultural cultivation, and discloses a three-dimensional cultivation method for improving the cultivation benefits of pelteobagrus fulvidraco.Through the research on the growth and reproduction characteristics of the pelteobagrus fulvidraco, a three-dimensional cultivation mode of pelteobagrus fulvidraco-solenaia oleivora is adopted, wherein pelteobagrus fulvidraco cultivation is taken as the main mode, combined with solenaia oleivora cultivation; according to the cultivation mode, the load of a water ecological cultivation system is lightened in real time, competitive fishes do not need to be stocked, so that the cultivation density is improved; excess nutrient substances in pond bottom mud and water body are effectively utilizedcombined with the solenaia oleivora cultivation mode, and eutrophic substances are taken away in a mode that the eutrophic substances are taken as feeds for the pelteobagrus fulvidraco and harvest mature solenaia oleivora, so that in-situ restoration of the environment is realized; the adverse effects of eutrophication on the surrounding ecological environment are reduced, the input of feeds, fishmedicines and labor is reduced, the breeding benefits of the pelteobagrus fulvidraco are improved, and the problems of low yield, poor benefits and large pollution of the existing pelteobagrus fulvidraco breeding are solved.

Description

technical field [0001] The invention belongs to the technical field of modern agricultural breeding, and in particular relates to a three-dimensional breeding method for improving the breeding efficiency of yellow catfish. Background technique [0002] The yellow catfish has a body length of about 20cm, a straight ventral surface, a flattened rear half of the body, and a slender tail peduncle. The head is large and flat, the snout is short, round and blunt, the upper and lower jaws are slightly equal in length, the mouth is large and inferior, and there are villiform tooth bands on the two faces and the palate. Eyes small, lateral. There are 4 pairs of barbels, the end of the nasal barbels can extend to the back of the eyes, 1 pair of maxillary barbels is the longest, and 2 pairs of palps are shorter than the maxillary barbels. Body naked without scales, lateral line complete. Omnivorous, the staple food is benthic small animals, shrimps, small aquatic insects and some in...
