Procypris rabaudi fry ecological pond cultivating method

Abstract

The invention relates to a procypris rabaudi fry ecological pond cultivating method, which comprises the following steps of (1) base fertilizer fermentation and inoculation live prey oriented cultivation; (2) base fertilizer application and prey organism enlargement culture; (3) procypris rabaudi larva fish pool fry cultivation: firstly, larva fish still water cultivation is carried out, prelarval fish is obtained, and then, the prelarval fish is cultivated into procypris rabaudi fries after the micro flowing water cultivation is carried out. The procypris rabaudi fry ecological pond cultivating method provided by the invention has the advantages that the problem of difficult scale cultivation of the procypris rabaudi fries can be solved, through the integral utilization of a series of key technologies of fermented manure filtrate water eutrofication, prey organism oriented cultivation, fry cultivating pond water quality and substrate regulation and control by compound probiotics and substrate modifying agent and the like, the stable water quality condition is maintained, meanwhile, the sufficient palatability live prey is provided for procypris rabaudi larva fish, the transparency of the fry cultivating water body is reduced through mass propagation of planktonic microalgae, the probability of disease outbreak caused by photophobia stress and cluster of the fries is reduced, and the scale cultivation of procypris rabaudi fries is realized.

Description

Technical field [0001] The invention relates to a method for cultivating fish species, in particular to an ecological pond cultivating method for rare and unique fish Iwabara carp seed. Background technique [0002] Rock carp Procyprisrabaudi (Tchang) commonly known as rock carp, rock carp, belongs to Cypriniformes, Cypriniformes, Cypinidae, Cypininae, Procypris, and mainly inhabits cavities at the bottom of rivers. between. Iwabara carp is mainly distributed in the main branches of the upper reaches of the Yangtze River and the middle and lower reaches of the Jinsha River, and is more distributed in rivers in Sichuan Province. However, in recent years, due to man-made overfishing, water pollution, and cascade hydropower development in the middle and lower reaches of the Jinsha River, the wild resources of Yanyuan carp have declined sharply. The wild population is endangered and has been included in the "Red Book of Endangered Animals in China." [0003] The establishment of a la...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an ecological pond cultivation method for Iwahara carp seedlings, which can solve the difficult problem of large-scale cultivation of Iwahara carp seedlings. A series of key technologies such as substrate improvement agent to regulate the water quality and substrate of the nursery pond, to provide sufficient palatable biological bait for Iwahara carp larvae while maintaining stable water quality conditions, and reduce the transparency of the seedling water body through the proliferation of planktonic microalgae and reduce the light fear of fry Probability of disease outbreaks due to stress and clustering, to realize large-scale cultivation of Iwahara carp seedlings
