Embodiment Construction

[0022] The present invention will be further described below with embodiment.

[0023] The method for artificial reproduction of carp, comprising the following steps:

[0024] ①, Breeding of broodstock

[0025] a. Phase I hydrostatic cultivation. The present embodiment is to capture 125 strong and lively wild porpoises of 1 to 4 ages from the lake in winter as backup broodstock. Its average individual body weight is 1.3kg, wherein the smallest individual is 0.5kg, and the largest individual is 7.0kg. After soaking and disinfecting in 5% salt water, put them all into a rectangular still water pond with an area of ​​10 mu. The depth of the pond is 1.5m, and the sludge at the bottom of the pond is less than 15cm. Use the "four major family carp" live fry that are suitable for the backup broodstock provided by the special pond breeding, and keep the weight ratio of the feed fish to the total weight of the carp not less than 1.0 throughout the breeding period, and the individual ...

Abstract

An artificial reproduction method for yellowcheck carp includes such steps as culturing the parents of yellowcheck carp by combining static water with flowing water and providing living feed for increasing the sexual mature rate to 100%, oxytocia by external hormone, ovipositing in reflux pool, incubating by careful manage for increasing the incubating rate to 88.3%, and culturing minnow by controlling the quality of water and feed for increasing its survival rate to 74.8%.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to an artificial propagation method for carp. Background technique [0002] Elopichthys bambusa, commonly known as cross catfish or cross fish, belongs to Cyprinidae, Cyprinidae, Elopichthys subfamily, Elopichthys genus, is a kind of river migratory fish, mainly distributed in the rivers along the middle and lower reaches of the Yangtze River in my country in the lake. The carp is large and has delicious meat. It is a large freshwater economic fish and is deeply loved by the masses. However, since the 1970s, due to the construction of water conservancy projects that cut off or hindered the migration channels of the carp and environmental pollution, the number of wild carp has gradually decreased. By the 1980s, the number of carp in rivers and lakes had become rare. exist. In order to protect this precious fish resource and meet the living...
