Problems solved by technology

The average individual weight of big fin fish is about 0.5 kg, and the largest individual can reach 5 kg. It is rich in protein, tender and delicious, and is deeply loved by consumers. At present, wild big fin fish can no longer meet the market demand

Embodiment 1

[0032] combine figure 1 Shown, following is an embodiment of the present invention:

[0033] 1) Feeding bigfin fish fry until they reach sexual maturity

[0034] If it is a wild big fin carp, feeding and domestication is also required. In this process, the fry are soaked in 1.5-2% salt water for 3-5 minutes and then put into the pond, and fed with water worms 5-15 days before entering the pond. After 15 days, its fry were fed with the soft pellets of 40% (weight) protein content processed together with fresh surimi and powder, and the daily feeding amount was 2% of body weight. When the water temperature is lower than 18 degrees, gradually reduce the amount of feeding, and do not feed below 12 degrees. The fed fish ponds are flushed regularly every day, and the water is changed regularly every month to ensure good water quality. At the same time, the aerator is turned on regularly every day to ensure that the broodstock is not hypoxic. Feed in this way until the ovary of ...

Embodiment 2

[0049] In this embodiment, different from 1) to 6) of Embodiment 1, in step 5), the fertilized eggs are placed in the hatching bucket for hatching under running water.

Abstract

The invention provides an artificial propagation method for mystus macropterus. The artificial propagation method comprises the following steps of fry feeding, artificial oxytocin injection, spawn taking and sperm collection, fertilization, incubation and temporary rearing and cultivating. LHRH (luteinizing hormone releasing hormone)-A2, DOM (dissolved organic matters) and HCG (human chorionic gonadotropin) serve as the oxytocin, the spawning rate in artificial hastening parturition reaches 74%, a circumstance that propagation is carried out by killing the mystus macropterus is avoided, the spontaneous delivery rate reaches 62%-76%, and the fertility rate reaches 14%-32%. In an incubation process, fertilized spawns are placed in hyperoxic flowing water, the incubation rate reaches 27.5%-76.19%, and the temporary rearing survival rate reaches 87.6%. The fries of the mystus macropterus eat feedstuff with 40% of protein level when the fries are small, the feedstuff is processed by fresh minced fillet and powder, the fries are easy and convenient to feed, and the mystus macropterus can be articially propagated in batches.

Description

technical field [0001] The invention belongs to fish breeding technology, in particular to an artificial breeding method of bigfin carp without killing fish and extracting sperm. Background technique [0002] The big fin fish belongs to Siluriformes, distributed in various water systems from the Yangtze River to the Pearl River. It is a bottom-dwelling fish. It mostly inhabits the main streams and tributaries of rivers with fast currents and rocky bottoms, and likes to cluster. Foraging at night, mainly benthic animals, such as snails, mussels, aquatic insects and their larvae, shrimps, small fish, etc., and occasionally higher plant debris and algae. Eggs are laid on the flowing water beach from June to July, and the eggs adhere to the rocks for development. Distributed in various water systems from the Yangtze River to the Pearl River, it is more common in the middle and upper reaches of the rivers, and is one of the common edible fish. The average individual weight of b...
