Embodiment 1

[0015] The low-mortality breeding method of the mullet specifically includes the following steps: 1) Determine the setting environment of the pond: select a field with open ground, flat terrain, quiet environment, convenient transportation, and supporting electricity. The bottom of the pond is clay, and the thickness of the silt at the bottom is 10~ 20 cm; 2) Determine the size of the pond: the pond is a "mouth" shape, and the outer height is 1.0~1.5 m; 3) Clean up the garbage in the pond: clean up the plastic, glass slag and other garbage inside the mud at the bottom of the pond; 4) At the outlet of the pond A groove about 15-20 cm deeper than other places is dug at the bottom, and an escape net is set up; 5) Oxygenation equipment is installed at the bottom of the pond to ensure that the dissolved oxygen reaches 4-12 mg / L; 6) After the pond is injected The groundwater pumped out by the water pump, supplemented with acidic potassium permanganate solution to disinfect the pond w...

Abstract

The invention discloses a feeding method for lowering the case fatality rate of common sucker. The method specifically includes the following steps that 1, the pond setting environment is determined; 2, the pond specification is determined; 3, pond waste is cleaned; 4, a groove which is 15-20 cm deeper than other places is dug in the bottom of a drainage opening end of a pond, and an anti-escape mesh is arranged; 5, oxygen charging equipment is arranged at the bottom of the pond; 6, underground water pumped through a water pump is injected into the pond, and water for the pond is sterilized in cooperation with an acid potassium permanganate solution; 7, fertilizer is fed into the fish pond; 8, aquatic plants are planted in the fish pond; 9, after the aquatic plants grow for five weeks, phagostimulant is spread into the pond, the feed is fed, and common sucker is put into the pond; 10, fingerling is sterilized; 11, fry is fed into the pond. By means of the low-case-fatality-rate common sucker feeding method, the yield-increasing effect is obvious in a short time, the survival rate is high, and the feeding method is suitable for industrialized large-scale development.

Description

technical field [0001] The invention relates to the field of fish breeding, in particular to a breeding method for reducing the fatality rate of mullet. Background technique [0002] Rouge fish, also known as yellow row, blood row, powder row, fire bream, wood leaf plate, red fish, purple bream, swallowfish, fire row, Chinese sail fin sucker, etc., belongs to Cyprinidae Suction Cyprinidae, living in lakes , In rivers, larvae and adults have different shapes, habitats and biological learning characteristics. Juveniles like to cluster among the gravels with slow water flow, and they mostly move in the upper layer of water bodies, while subadults live in the middle and lower layers, and adults like to live in rivers In the open water area, it moves quickly and agilely. The mullet eats frequently and is omnivorous. It can eat regardless of the food status. Its food includes brine shrimp, red earthworms and vegetables. Under artificial breeding conditions, in addition to feeding...
