Problems solved by technology

However, due to the extensive reclamation of coastal tidal flats in the past 20 years, the habitat area of ​​the large mudskipper has been continuously reduced, coupled with environmental pollution and overfishing, etc., the survival rate of wild fry of the large mudskipper is low, and even the fry after artificial domestication and breeding are easy to die , so how to improve the survival rate of fry and reduce the cost of breeding has become an urgent problem for those skilled in the art

Embodiment 1

[0022] A method for ecologically efficient breeding of large mudskippers is characterized in that it comprises the steps of:

[0023] (1) Disinfection of fish ponds: Choose a sunny day, drain the fish pond water, sprinkle disinfectant, and expose to the sun for 1 day; turn the bottom mud 10cm deep, and rake the bottom mud finely, dry it for 2 days, and then pour it into the fish pond. Inject water into the pond so that the water depth is 3 cm, and soak for 1 day; the preparation method of the disinfectant is: in parts by mass, 80 parts of Chlorophytum, 50 parts of Malan, and 100 parts of garlic straw are mixed and dried until the moisture content is 15%. , be prepared into a powder with a particle size of 0.1mm, and then mix evenly with 20 parts of quicklime and 30 parts of plant ash, and the usage amount of the disinfectant is 20kg / mu;

[0024] (2) Cultivate diatoms: Keep the water depth of the fish pond at 3cm, spread the basic culture in the fish pond, and cover the fish po...

Abstract

The invention relates to the field of breeding technology, especially to an ecological efficient breeding method of Boleophthalmus pectinirostris. The method comprises the following steps: (1) disinfection of a fish pond; (2) cultivation of diatom; (3) placement of fish fry; and (4) management of the fish pond. In the invention, unfavorable microorganisms are reduced by the fish pond treatment inthe early stage, and photosynthetic bacteria are added in the bait and EM bacteria are used in a fertile solution. Thereby, the virtuous cycle of the fish pond's micro-ecology is effective promoted, the growth of the algae is enhanced and the vigor of the fish fry is raised.

Description

technical field [0001] The invention relates to the technical field of breeding, in particular to an ecologically efficient breeding method for mudskippers. Background technique [0002] The big mudskipper (Boleophthalmustinirostris) belongs to the order Perciformes, the suborder Gobiodei, the family Periophthalmidae, and the genus Boleophthalmus. The big mudskipper is distributed in China, North Korea, Japan, Myanmar and the Malay Peninsula, and in China, it is mainly distributed in the coastal areas of Jiangsu, Zhejiang, Fujian, Taiwan, Guangdong and Guangxi. Mudskippers inhabit mudflats and mangrove areas in the intertidal zone of estuaries and harbors. They are warm-water, wide-temperature, and salty cave fish. Their juveniles and adults mainly feed on benthic diatoms. They have short food chains, few diseases, and high survival rates. It has the characteristics of high production cost, low cost of breeding, convenient management, no pollution to the environment and res...
