Embodiment 1

[0034] The cultivation of yellow catfish in the same year includes two stages: seed cultivation and adult fish cultivation.

[0035] 1. Seed cultivation

[0036] (1) On May 15, 2014, a 5.2 mu pond was selected, and the quicklime dry method cleared the pond (80kg of quicklime per mu). After 10 days of clearing the pond, 80 mesh sieves were injected to filter the water, so that the depth of the pond water reached 70cm; June 1 On June 2, insecticide and disinfection were carried out on the pool water; on June 2, 1 million yellow catfish fry were put in after swimming.

[0037] (2) After the fish fry are put into the pond, the whole pond will be sprinkled with special powder for yellow catfish on the second day, 4kg of special powder for yellow catfish will be sprinkled every day, 4 times a day (9:00 / 13:00 / 17:00 / 20 :00 once each).

[0038] (3) When the fry were 10 days old, the pool water was disinfected and disinfected once. The next day, start taming fish fry to ingest No. 0 ...

Embodiment 2

[0046] 1. Seed cultivation

[0047] (1) On May 23, 2014, a 3.8-acre pond was selected, and the quicklime dry method cleared the pond (80kg of quicklime per mu). After 10 days of clearing the pond, 80 mesh sieves were injected to filter the water, so that the depth of the pond water reached 70cm; June 8 On June 9, insecticide and disinfection were carried out on the pool water; on June 9, 1 million yellow catfish fry were put in after swimming.

[0048] (2) After the fish fry are put into the pond, the whole pond will be sprinkled with special powder for yellow catfish on the second day, 3 kg of special powder for yellow catfish every day, 4 times a day (9:00 / 13:00 / 17:00 / 20 :00 once each).

[0049] (3) When the fry were 12 days old, the pool water was disinfected and disinfected once. The next day, start taming fish fry to ingest No. 0 extruded feed (No. 0 extruded feed for yellow catfish special purpose, particle diameter 0.8 mm), and mix it with the special powder for yello...

Abstract

The invention discloses a pelteobagrus fulvidraco current-year maturing efficient breeding method and belongs to the field of aquaculture. The method comprises the steps of 1, feeding young pelteobagrus fulvidraco with artificial compound feed early; 2, increasing pelteobagrus fulvidraco feeding frequency; 3, increasing feeding amount at night and in the morning at high-temperature seasons; 4, maintaining the stability of the ecological environment of a pond. Compared with traditional breeding modes, the method has the advantages that pelteobagrus fulvidraco growing speed is increased effectively, breeding period is shortened, breeding cost is reduced, and fund return is accelerated; the risk of diseases of two-year fishes is avoided, and loss caused by weight losing after wintering is avoided; by feeding young fish with artificial compound feed early, the survival rate of young pelteobagrus fulvidraco is increased greatly; pelteobagrus fulvidraco feeding frequency is improved, feed utilization efficiency is improved, and food coefficient is reduced; insect killing, disinfection, water transfer and base change are conducted periodically, the substrate and water environment can be improved, pelteobagrus fulvidraco is prevented from eating natural food, and fast growth is maintained.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a cultivation method for yellow catfish bred in the same year. Background technique [0002] Pelter catfish is unique to East Asia. Its tender meat, delicious taste and no intermuscular thorns are very popular among consumers. The continuous growth of market demand and the gradual reduction of natural resources have promoted the rapid development of my country's yellow catfish aquaculture industry, and it has been widely promoted in various parts of the country. However, there are still many deficiencies in the traditional culture mode of yellow catfish: [0003] 1. The phenomenon of high early mortality of fry is serious [0004] In many areas, yellow catfish still adopts the traditional breeding mode of splashing soybean milk, and the fish fry are not transferred to food in time, resulting in mass death of fish fry; [0005] 2. Fish species overwinter and lose fat, and...
