A kind of strengthened cultivation method of broodstock of wheat ear fish

Abstract

The invention discloses a strengthening breeding method of parent fishes of pseudorasbora parva. The method includes the steps of parent fish selection, pond selection and treatment, parent fish strengthening breeding, water temperature adjustment, daily management and the like. According to the strengthening breeding method, gonad development of the parent fishes of the pseudorasbora parva can be stimulated, and the success rate of parent rearing maturity is improved; meanwhile rapid growth of the parent fishes is promoted, the survival rate of the parent fishes is improved, the problem that the parent quality and the survival rate of the pseudorasbora parva are hard to guarantee is effectively solved, and the method lays a technical foundation for artificial breeding of the pseudorasbora parva in China and has important significance for industrialization exploitation of the pseudorasbora parva.

Description

technical field [0001] The invention relates to a method for intensified breeding of broodstock of cereus, belonging to the technical field of aquaculture. Background technique [0002] Pseudoras boraparva (Pseudoras boraparva), commonly known as Luohan fish, Mannenzi, sand fish, green skin tender, willow leaf fish, steal mouth fish, etc., is a common and main small wild fish, common in major water systems in eastern China , North Korea and Japan are also distributed. [0003] As a wild miscellaneous fish in the past, wheat ear fish was mainly used as biological bait for breeding carnivorous fish such as mandarin fish and sandfish. In recent years, people's consumption has diversified, and wheat ear fish has begun to go to the dining table. The market price is about 28 yuan / kg, and its economic value is gradually emerging. Therefore, it is of great significance to carry out the research on the intensive breeding technology of the broodstock of the crocodile carp for artifi...
