Abstract

The invention belongs to the field of aquaculture, and discloses an artificial breeding method for homatula variegata. The method comprises the following steps of parent fish selection: selecting parent fish in sexual maturity and age of 3 years or above; parent fish breeding: feeding spawning induction feed in one week before spawning induction, wherein 5-12 grams of biological oxytocin is addedinto the spawning induction feed per kilogram, and feeding is continuously conducted for one week; artificially induced spawning and fertilization: in the breeding season of the homatula variegata, selecting parent fish in sexual maturity, and injecting oxytocin to induce spawning and spermiation; evenly spreading fertilized ova in an incubator for incubation; fry breeding: after the fertilized ova in the incubator are all hatched for 2-7 days, feeding cooked egg yolks and fish meat; after 7-10 days of incubation, conducting transferring into a fry breeding pond, feeding initial feed, gradually using mixed feed for food domestication when the fry body length reaches 2 cm, and cleaning and disinfecting the pond to prevent diseases. The artificial breeding method greatly shortens the time ofbreeding of the homatula variegata, improves the fertilization rate and hatching rate, and improves the yield of the homatula variegata.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an artificial breeding method for Homeric loach. Background technique [0002] Homeric loach belongs to the subfamily of Cypriniformes, Reptilidae, and belongs to the endemic group of my country. Most of the fish species are large in number, distributed continuously, and have a complex age structure. They are widely distributed in the Yellow River, Yangtze River, Pearl River and Lancang River water systems in my country. It is a small fish with a body length of 10-17cm. It lives on the bottom and likes to live in rocky caves washed by flowing water. It usually lives in a large number in the tributaries of mountainous areas. When the flood comes, it will swim out to look for food and be taken away by the flood. Comes with bait. It usually likes to inhabit rock crevices, crevices or backwater bays with many boulders. [0003] At present, most fish can obtain fertilized eggs t...
