Silver carp breeding method

Abstract

The invention discloses a silver carp breeding method. The silver carp breeding method comprises the following steps that 1, a place with a water source is selected for construction of a pond, the pond is provided with a water inlet and a water outlet, 85-95 kg of quick lime is evenly spread into per mu of the whole pond, the pond is disinfected and aired for 13-15 days, then water is introduced into the pond until the water depth of the pond reaches 2.4-2.5 m, sand sludge with the thickness of 10-11 cm is laid on the bottom of the pond, and 85-120 kg of a fertilizer is splashed to per mu of the whole pond; the fertilizer is formed by fermentation of raw materials, and the raw materials comprise, by weight, 30-33 parts of chicken manure, 52-55 parts of stalks, 10-13 parts of shrimp shell meal, 13-15 parts of yam peels and 20-22 parts of sunflower stalks; a preparing method of the fertilizer comprises the steps that the stalks, the yam peels and the sunflower stalks are cut into 1-2 cmlong small segments, and the small segments, the chicken manure, the shrimp shell meal and an appropriate amount of water are mixed, placed in a fermentation tank, stacked and fermented for 11-12 days, wherein stirring is conducted for 20-23 minutes every day during fermentation. By the adoption of the silver carp breeding method, the fry incidence rate can be reduced, the utility ratio of feed isincreased, accordingly, the yield of products is increased, and the quality of the products is improved.

Description

technical field [0001] The invention belongs to the technical field of silver carp cultivation, and in particular relates to a method for cultivating silver carp. Background technique [0002] At present, in the process of cultivating silver carp artificially, we only pay attention to the growth and weight gain of fry. Often, due to feeding and improper management, the survival rate of fry is low, the output decreases, and the quality of fish meat is not good, which brings certain economic losses to farmers. Therefore need badly a kind of good silver carp breeding method, improve fry survival rate, fish meat quality. Contents of the invention [0003] 1. Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide a method for cultivating silver carp to solve the technical problem. 2. Technical solution [0005] In order to solve the technical problems, the technical solution adopted in the present invention is: a me...
