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

Embodiment 1

[0026] The application of this method in Xiluodu Xiangjiaba Rare and Specific Fish Breeding and Release Station of China Three Gorges Corporation is as follows:

[0027] A kind of ecological pond cultivation method of Yanyuan carp seedling, the method comprises the following steps:

[0028] 1) Fermentation of basal fertilizer and directional cultivation of biological bait for inoculation: Fermentation of organic fertilizer and directional cultivation of bait organisms were carried out 15 days before the cultivation of Iwahara carp in the pond;

[0029] 2) Application of basal fertilizer and expanded cultivation of bait organisms: the area of ​​the seedling pond is 100m 2 The oval-shaped open-air cement pond, the fish fry began to enter the pond one week before the pond, the source water was filtered through an 80-mesh sieve, and the water was added to 60cm, in order to prevent the premature application of the base fertilizer from causing the water quality in the nursery pond t...

Embodiment 2

[0042] The application of this method in Xiluodu Xiangjiaba Rare and Specific Fish Breeding and Release Station of China Three Gorges Corporation is as follows:

[0043] A kind of ecological pond cultivation method of Yanyuan carp seedling, the method comprises the following steps:

[0044] 1) Fermentation of basal fertilizer and directional cultivation of biological bait for inoculation: Fermentation of organic fertilizer and directional cultivation of bait organisms were carried out 10 days before the cultivation of Iwahara carp larvae in the pond;

[0045] 2) Application of basal fertilizer and expanded cultivation of bait organisms: the area of ​​the seedling pond is 100m 2 The oval-shaped open-air cement pond, the fish fry began to enter the pond one week before the pond, the source water was filtered through an 80-mesh sieve, and the water was added to 70cm, in order to prevent the water quality in the nursery pond from "aging" due to premature application of base fertil...

Embodiment 3

[0058] The application of this method in Xiluodu Xiangjiaba Rare and Specific Fish Breeding and Release Station of China Three Gorges Corporation is as follows:

[0059] A kind of ecological pond cultivation method of Yanyuan carp seedling, the method comprises the following steps:

[0060] 1) Fermentation of basal fertilizer and directional cultivation of biological bait for inoculation: Fermentation of organic fertilizer and directional cultivation of bait organisms were carried out 12 days before the cultivation of Iwahara carp in the pond;

[0061] 2) Application of basal fertilizer and expanded cultivation of bait organisms: the area of ​​the seedling pond is 100m 2 The oval-shaped open-air cement pond, the water began to enter the pond one week before the fish fry, the source water was filtered through an 80-mesh silk screen, and the water was added to 65cm, in order to prevent the water quality in the seedling pond from "aging" due to premature application of base ferti...

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 seedlings of the rare and unique fish Iwahara carp. Background technique [0002] Procyprisrabaudi (Tchang), commonly known as rock carp and rock carp, belongs to Cypriniformes, Cyprinidae, Cypininae, and Procypris. It mainly inhabits rock crevices at the bottom of rivers between. Iwahara carps are mainly distributed in the main and tributaries of the upper reaches of the Yangtze River and the middle and lower reaches of the Jinsha River, and are mostly distributed in rivers in Sichuan Province. However, in recent years, due to human 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, and the wild population is on the verge of extinction. It has been listed in the "China Red Data Book of Endangered Animals". ...
