Embodiment 1

[0023] The technical scheme of the present invention is to combine the larvae temporarily raising and the summer flower cultivation stage into one, and the concrete scheme (process) is as follows:

[0024] (1) Cultivation tank and seedling assembly

[0025] See attached figure 1 , it is the structural representation of a kind of cultivating pond provided by the technical scheme of the present invention; The cultivating pond is the earthen pond 1 of 2~3 mus, and bottom silt is thick 25~30cm, and yellow catfish fry has the habit of avoiding light, so it is placed on the backside of the earthen pond Putting wave-type asbestos tiles or color steel plates into the bottom of the pool is the temporary raising area 3, the area of ​​the temporary raising area is 1 to 1.5% of the cultivation pool, and the corrugation height is 3 to 5 cm. Drain the water 15 days before the seedlings, clear the pond with 150-200kg / mu of quicklime, and then dry the pond to kill the pathogenic organisms in...

Embodiment 2

[0037] The implementation pond area is 2.2 mus. On May 18, 400 kg of quicklime was used to dry the clear pond and expose it to the sun. On May 25, 50 kg of fermented rapeseed cake was sprinkled on the bottom of the pond, and the temporary larvae of yellow catfish were built according to the technical scheme of embodiment 1. In the breeding area, set up a 150W blower, several oxygen increasing pipes, 24 oxygen increasing heads, and 6 corrugated asbestos tiles of 68cm×200cm. Put 50cm of outer lake water on May 26, and at the same time, put 18 fertilizer slow-release bags, each containing two-thirds of a bag of fermented chicken manure; add water to 70cm on May 29, and put 3 There are 350,000 day-old yellow catfish fry with a size of 0.7 to 0.8 cm, which are cultivated with increased oxygen. From June 1st, put a small amount of fish paste and broken yellow catfish feed on the asbestos tiles, twice a day, one-third from 7:00 to 8:00 am, and three-pointers from 4:00 to 5:00 pm of ...

Abstract

The present invention relates to a method for large-scale cultivating Yellow Catfish and belongs to the technical field of aquiculture. The larval fishes which are hatched for three days are put into the cultivation pond. The cultivate density of larval fishes is 150-200 thousand/mu. The larval fishes are cultivated to the Yellow Catfish with lengths of 2.5-3cm after 20-30 days. The cultivation pond is the earth pond with area of 2mu to 3mu. The thickness of slit on the base of pond is 25-30cm. The pond is placed with sustained-release bag which is filled with fertilizer. The sunny surface of pond back part is provided with a temporary cultivation area of which the area is 1-1.5% of the area of cultivation pond. The bottom adopts the hard material which is nontoxic and smooth at the surface and has the ripple shape. The temporary cultivation area is additionally provided with oxygen heads with the density of 1-2/square meter. The invention adopts a technique of building the temporary cultivation area for integrating the temporary cultivation stage and larvae cultivating. The method of the invention has the advantages of easy assembling, brief operating program, easy management, and high survival rate of larvae for above 80%. The sustained-releasing technique of fertilizer is adopted for keeping the cleanness of pond base and realizing non-pollution cultivation.

Description

technical field [0001] The invention relates to a fish breeding technology, in particular to a large-scale cultivation technology of yellow catfish fingerlings, which belongs to the technical field of aquaculture. Background technique [0002] Yellow catfish (Pseudobagrus fulvidraco Richardson) belongs to Siluriformes, Pleurodidae, and Pseudobagrus genus. It is widely distributed in major water bodies in my country and is a fish with high economic value. Its meat is tender, delicious, rich in nutritional value, and has no intermuscular thorns. It is deeply loved by the public, and the demand in domestic and foreign markets is increasing day by day. In addition, yellow catfish has the characteristics of strong adaptability to ecological environment, wide temperature resistance, strong disease resistance, miscellaneous food habits, low bait coefficient, and can be marketed live and fresh. Therefore, the development of yellow catfish aquaculture industry has good prospects. I...
