Large Misgurnus anguillicaudatus seed culture pond and large Misgurnus anguillicaudatus seed culture pond method

Abstract

The invention discloses a large-scale loach seedling cultivation pond, which comprises a square pond and a microporous aeration pipe, a water inlet faucet is arranged above the square pond, and a hollow first drainage cylinder is arranged at the bottom of the square pond , the lower end of the first drainage cylinder passes through the bottom of the square pool to communicate with the drain pipe, the wall of the first drainage cylinder is provided with several drainage holes, and the drainage holes are located above the bottom of the square pool, The microporous aeration pipe is arranged around the bottom of the square pool. The invention also discloses a method for cultivating large-scale seedlings of loach. By adopting the method, large-scale seedlings of loach can be cultivated with high breeding density and high survival rate. The yield per mu of loach seedlings can reach 1.3 million, and the survival rate Reached more than 60%, leading at home and abroad.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a large-size loach seed cultivation pond and a cultivation method. Background technique [0002] Loach (Misgurnus anguillicaudatus) belongs to fish class, Cyprinidae, loach family, loach genus. This species is widely distributed in countries and regions such as China, Japan, North Korea, Russia, and Southeast Asia. In my country, it is mainly distributed in natural waters such as rivers, ditches, paddy fields, ponds, lakes, and reservoirs in the eastern region of China. It has extremely high edible value and medicinal value. It is an important small economic fish in my country. [0003] In recent years, loach has become one of the best-selling species in the aquatic product market, but due to the increase in fishing intensity and the destruction of the natural water environment, its wild resources have declined sharply. At the same time, the quality of wild loach...

AI Technical Summary

Problems solved by technology

The artificial propagation of loach has been conquered long ago, but the cultivation technology of large-scale seedlings of loach has not been completely conquered so far.

At present, the breeding method of loach seedlings is relatively simple, and people usually use pond seine method to cultivate large-scale seedlings of loach. The cultivation efficiency of this method is very low.
