Embodiment 1

[0012] An ecologically efficient and healthy breeding method for Chinese soft-shelled turtles nested with yellow catfish, the method comprising the following steps:

[0013] (1) Fish pond selection: fish pond area 0.45hm 2 , The depth of the pond is 3m, and the thickness of the silt at the bottom of the pond is 15±2cm. East-west direction, rectangular shape, good lighting, no shelter around, solid embankment, watertight, flat bottom of the pool. The low quality is clay, the pond is easy to drain, and the inlet and outlet are installed with 40 mesh anti-escape nets. The water quality of the water source is fresh and pollution-free, in line with the "Fishery Water Quality Standard (GB11607-1989)".

[0014] (2) Cleaning and disinfection of fish ponds: Drain the pond water 20 days before stocking fish species, clean the ponds, remove weeds, etc. in the ponds, and expose them to the sun for several days. 10 days before stocking fish species, use quicklime 1125kg / hm 2 Disinfect ...

Abstract

The invention discloses a cultivation method for cultivating Chinese softshell turtles and yellow-head catfish meats. The method comprises the following steps: (1) draining water in a tank and exposing to sun, sterilizing by uniformly scattering calcined lime for sterilization, applying fermented organic manure after 2-3 days, and equipping an aerator; (2) breeding yellow-head catfish meat fingerlings which are 2-3cm per fish, and Chinese softshell turtle fingerlings which are 0.25-0.5kg per fish, regulating the amount of fodders once every 7-10h, and adding vitamins and / or saccharomycetes which take up to 5-10% of fodders in the fodders every 10-15 days; (4) after 7 days of breeding the fingerlings, spraying trichodina once, filling fresh water every 7-10 day once, and keeping the transparency of the cultivation water to be greater than 30cm; and (5) fishing once every 1-3 months. The healthy cultivation method for cultivating Chinese softshell turtles and yellow-head catfish meats with high efficiency is used for cultivating, so as to reasonably determine the breeding specification and cultivation density, improve the utilization factors of the tank water, control the cultivation risk, improve the comparative benefit of pond culture, therefore, the biological healthful aquaculture of cultivating Chinese softshell turtles and yellow-head catfish meats can be realized.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and more specifically relates to an ecologically efficient and healthy culture method for raising soft-shelled turtles in sets of yellow catfish. Background technique [0002] Yellow catfish (Pseudobagrus fulvidraco Richardson) is an important freshwater economic fish in my country. Its meat is tender, delicious and nutritious. The muscle protein content reaches 16.1%, and contains a variety of amino acids. It has no intermuscular spines and has a large edible part. , has the advantages of simple feeding, not easy to die, and wide temperature range. In recent years, the cultivation of yellow catfish has unshakably become the focus of freshwater aquaculture at this stage, and it is listed as the main famous and high-quality aquaculture species in Hubei Province. The aquaculture has developed rapidly and its scale has continued to expand. In 2012, the farming area of ​​yellow catfish in Hubei P...
