Embodiment Construction

[0022] A method for intensified breeding of broodstock of chrysalis, comprising the following steps:

[0023] (1) Broodstock selection

[0024] The broodstock comes from the surrounding natural lakes. In early December, select broodstock with healthy physique, complete scales, no disease or injury, body length > 500mm, and weight > 3g. Before the broodstock goes to the pond, sterilize it with 3% salt water for 8 minutes ;

[0025] (2) Pond selection and treatment

[0026] The area of ​​the pond is 1.5 mu, the water depth is 1.5 meters, and the slope ratio of the pond is 1:2.5. The inlet and outlet are arranged diagonally and there are fish blocking facilities to prevent predators from invading or fish escaping. Aquatic plants are planted in the pond to provide concealment for them. And the bottom of the pool is flat and has good water retention;

[0027] Before stocking the broodstock, dry the pond and expose it to the sun for about 1 month. Use 75kg of disinfectant to melt...

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] Pseudorasbora parva (Pseudorasbora parva), 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. Water system, North Korea, Japan also have distribution. [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 artificial breeding and to solve the seed ...
