Abstract

The invention discloses a complete technology for breeding and culturing Ictalurus punctatus and provides a more mature artificial breeding and culturing mode. The technology can be implemented by the following steps of: 1) artificial breeding, which comprises a serial of technical links such as parent introduction, selection, culturing, artificial induced spawning, incubation and the like, so as to supply sufficient high-quality fry for local region and neighboring regions; 2) fry culturing, by which massive high-quality fry can be cultured; and 3) adult fish culturing. A mature technology for culturing Ictalurus punctatus in a rice field pond at high yield and high efficiency is explored.

Description

A kind of channel catfish offspring seed cultivation method

Technical field

The present invention relates to a kind of varieties breeding, specifically is that a kind of channel catfish seed is cultivated.

Background technology

Channel catfish originates in U.S.'s Mississippi, is American-European main freshwater aquiculture kind, China in 1984 by Hubei Province's aquatic science institute first from U.S.'s breed that makes an experiment, and successfully grasp artificial propagation techniques.I am once during 2000-2002; Bear three of our province aquatic products and upgraded engineering project " channel catfish introduction, demonstration and industrialization development "; Formed the parent fish rearing of comparative maturity through the enforcements in 3 years, fry production process, and combine local aquatic products production characteristic; Carried out pond culture and rice field demonstration culture experiment; Form ripe channel catfish aquaculture model and the technology of a cover, obtained significantly economic benefit and social benefit, its seedling breeding, adult fish culture technology have reached province's advanced level.

The present invention realizes with following technical scheme: a kind of channel catfish offspring seed cultivation method,

It is characterized in that:

1) parent population select → hasten parturition → hatch → seed rearing → city's aquatic farm → periphery promotes and culture;

2) channel catfish artificial propagation: the parent population selection → parent fish rearing → hatching → fry rearing of hastening parturition.

Below in conjunction with embodiment to further explain of the present invention.

Embodiment

The introduction of technology catfish broodstock on the market of aquaculture farms for broodstock, artificial propagation, the implementation of a field with a base of farming methods, in order to point, free catfish technical advice means of achieving demonstration purposes, select Xuzhou representative fish farms demonstration farming, and the surrounding high management level of rice farming, which led farmers to join the surrounding area, and gradually extended to Suqian and the surrounding urban area.

Establishment cultural technique brochure, distribution surrounding area, and responsible technical training.

2, technology path

Parent population selects → hastens parturition → hatch → seed rearing → city's aquatic farm →

Periphery is promoted and is cultured

1) channel catfish artificial propagation: the parent population selection → parent fish rearing → hatching → fry rearing of hastening parturition

2) seed rearing: the pond selects → cleans up the pond → and fry puts in a suitable place to breed → feeding and management

3) adult fish culture: pond selection → fingerling stocking → feeding and management → rise and catch listing.

Claims (1)

1. channel catfish offspring seed cultivation method is characterized in that:

1) parent population select → hasten parturition → hatch → seed rearing → city's aquatic farm → periphery promotes and culture;

2) channel catfish artificial propagation: the parent population selection → parent fish rearing → hatching → fry rearing of hastening parturition.
