Embodiment Construction

[0023] The present invention will be further described below in conjunction with the embodiments, but it is not intended to limit the scope of the present invention, but only for illustration.

[0024] A kind of cultivation method of hybrid yellow catfish in the same year can be divided into two stages of seed cultivation and adult fish cultivation, and its specific process is as follows:

[0025] 1. Seed cultivation

[0026] (1) Preparation of the seed cultivation pool

[0027] Cement ponds or soil ponds can be used as cultivation ponds. Concrete pond with adjustable overflow hole, area 20m 2 -40m 2 , the pool depth is 1.0m-1.2m; the water depth is controlled between 0.5m-1.0m according to the size of the seedlings. The suitable area of ​​the soil pond is 2000m 2 -3500m 2 , The water depth is controlled between 0.5m-1.5m according to the size of the seedlings. Earthen ponds should be cleared and disinfected 10-15 days in advance in accordance with the provisions of SC / ...

Abstract

The invention provides a current-year aquaculture method of hybrid pelteobagrus fulvidraco. The aims of current-year fry breeding, current-year aquaculture and current-year benefiting can be achievedby a series of technical processes such as fry breeding, reasonable stocking, domesticated feeding, water quality management, daily management, disease control and efficient fishing. Known from a contrast experiment, the growth performance of the hybrid pelteobagrus fulvidraco is obviously superior to that of common pelteobagrus fulvidraco, the hybrid pelteobagrus fulvidraco propagated in the current year can grow to the weight of 50-150 g, the aquaculture period of the pelteobagrus fulvidraco is greatly shortened, and the current-year aquaculture method is an efficient aquaculture technical method of hybrid pelteobagrus fulvidraco.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for growing hybrid yellow catfish in the same year. Background technique [0002] The hybrid yellow catfish is the offspring fish obtained by crossing the yellow catfish as the female parent (♀) and the yellow catfish as the male parent (♂). The hybrid yellow catfish is relatively similar to the yellow catfish in terms of morphological characteristics. There is no obvious difference in color, the front part of the head is slightly narrower than that of the yellow catfish, and there is a small black spot at the end of the caudal fin. The food habits of hybrid yellow catfish are the same as those of yellow catfish. They are omnivorous fish that mainly feed on animal bait. The fry stage feeds on rotifers, cladocerans, water earthworms, etc., and the adult fish stage mainly eats various small fish and shrimps. . When breeding artificially, they can eat both...
