Problems solved by technology

Although there have been some reports on the culture of Schizothorax, there are few techniques specifically for the artificial culture of Schizothorax
[0003] The Chinese patent applications whose publication numbers are CN102484983A and CN200410022179.7 respectively disclose methods for the artificial propagation of Schizothorax, mainly disclosing the cultivation conditions in the stages of insemination, hatching, and seedling cultivation, such as temperature, time, and environmental requirements. The bait for juvenile fish is only biological bait such as water earthworms, Tenebrio molitor, and fly maggots. Although this type of bait can provide more nutrients, the nutrition is not comprehensive, and there is no suitable food for juvenile fish at different stages of growth. Feeding bait, and there is no scientific method for cultivating fry of Schizothorax

Abstract

The invention discloses a fry culture cultivating method for schizothorax prenanti. After a fish pond is disinfected, fish fry disinfected with a povidone-iodine solution are put in the pond, micro-flow water is adopted for cultivation, cooked egg yolk is thrown and fed to the fry for several days, plankton bait is thrown and fed to the fry after 5-7 days, cut water earthworms and broken juvenile schizothorax prenanti materials are thrown and fed to the fry after 20 days, and juvenile schizothorax prenanti feed is thrown and fed to the fry till the fry reach the specification of larva fish. The schizothorax prenanti fish fry cultivated through the method are low in cost, high in survival rate and quick in growth, the cooked egg yolk, the rotifer and cladocera plankton bait, and the water earthworms and the juvenile schizothorax prenanti feed are thrown and fed to the fry in a staged mode, and therefore the high growth rate can be kept at each stage.

Description

Technical field [0001] The embodiment of the present invention relates to the fish farming industry, and more specifically, the embodiment of the present invention relates to a method for raising and cultivating Schizophyte fry. Background technique [0002] Schizophrenia is also called elegant fish, schizophrenia, thin turtle, sclerophyll. It is a cold-water fish and is a demersal fish. It requires a lower water temperature environment and likes to live in the junction of rapid and slow currents. Most of them live in slow currents. During the feeding season, they are active in environments with sand and gravel and turbulent water. Short-distance reproductive migration occurs. Females need to reach sexual maturity at 4 years of age, and males generally reach sexual maturity at 3 years of age. . Schistophyta is distributed in Minjiang River, Dadu River and other water systems. It is an important edible fish in the upper reaches of the Yangtze River. It is large in size, generally...
