Description

The method for breeding of channel catfish

Technical field

The present invention relates to the method for breeding of a kind of channel catfish, belong to technical field of aquaculture.

Background technology

Channel catfish is also known as ditch Nian, belongs to Silurformes, section Fish.Channel catfish is Hubei Province's aquatic science research A kind of section Fish of simultaneously introducing with clouding in 1984, through research in a few years and promote cultivation, it was demonstrated that this kind of fish It is suitable for China's most area cultivation.Developing in recent years quickly, cultured area expands rapidly, and economic and social benefit is notable, Become one of important industry of China's sea-farming.

The cultivation of channel catfish at present is primarily present following problem: poor growth, disease incident are high, specification is irregular Etc. problem.Therefore improving further and industrialization of channel catfish cultivation level is constrained.

Summary of the invention

In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that the method for breeding of a kind of channel catfish.

The method for breeding of the channel catfish of the present invention, comprises the steps:

1) pond selects: select area about 0.3 hectare to be advisable, the depth of water 1.5～the pond of 2 meters；Pond is leveled, At the bottom of smooth pond, going to cut weeds, pond part the to be removed bed mud that mud is blocked up, available slush pump is extracted out, in order to avoid being harmful to fish body In the accumulation of material and breeding process, water quality is wayward；

2) fingerling selects: select body constitution healthy and strong, and energetic, body colour is consistent, and body surface smooth and mucus enrich, and body examination has irregularly Speckle, not damaged, the fingerling that specification is the most neat；Fingerling stocking density: about 10 cm specification is 350 ~ 400 tails/m² ； 50 ~ 100 g/ tail fingerlings are 100 ~ 250 tails/m²；

3) throw something and feed management: using fish special compound feed, feed request protein content is higher；Channel catfish cultivates with people Work mixed feed is main, selects the expanded buoyancy fish special compound feed of professional production manufacturer production, crude protein content requirement Reach 30%～35%；Feedstuff is preferably processed into heavy property and two kinds of granules of buoyancy, when water temperature is more than 15 DEG C；Throw something and feed 2 every day Secondary, at each 1 time of the most upper and lower noon, bait throwing in scope should expand as far as possible；

4) daily management: observe the situation of ingesting of fish every day, adjust daily ration, feeding quantity in time, the channel catfish tolerance to hypoxia Relatively poor, to prevent from raising the nose above water to breathe and general pond, often change water, to keep pure and fresh water quality, in fishpond, the dissolved oxygen of water should be frequent It is maintained at more than 3 mg/litre.

The method for breeding of the channel catfish of the present invention, has the following technical effect that and provides good living environment, carry High survival rate, survival rate is up to 90%, it is ensured that being smoothed out of cultivation.

Detailed description of the invention

Embodiment 1

The method for breeding of the channel catfish of the present invention, comprises the steps:

1) pond selects: select area about 0.3 hectare to be advisable, the depth of water 1.5～the pond of 2 meters；Pond is leveled, At the bottom of smooth pond, going to cut weeds, pond part the to be removed bed mud that mud is blocked up, available slush pump is extracted out, in order to avoid being harmful to fish body In the accumulation of material and breeding process, water quality is wayward；

2) fingerling selects: select body constitution healthy and strong, and energetic, body colour is consistent, and body surface smooth and mucus enrich, and body examination has irregularly Speckle, not damaged, the fingerling that specification is the most neat；Fingerling stocking density: about 10 cm specification is 350 ~ 400 tails/m² ； 50 ~ 100 g/ tail fingerlings are 100 ~ 250 tails/m²；

3) throw something and feed management: using fish special compound feed, feed request protein content is higher；Channel catfish cultivates with people Work mixed feed is main, selects the expanded buoyancy fish special compound feed of professional production manufacturer production, crude protein content requirement Reach 30%～35%；Feedstuff is preferably processed into heavy property and two kinds of granules of buoyancy, when water temperature is more than 15 DEG C；Throw something and feed 2 every day Secondary, at each 1 time of the most upper and lower noon, bait throwing in scope should expand as far as possible；

4) daily management: observe the situation of ingesting of fish every day, adjust daily ration, feeding quantity in time, the channel catfish tolerance to hypoxia Relatively poor, to prevent from raising the nose above water to breathe and general pond, often change water, to keep pure and fresh water quality, in fishpond, the dissolved oxygen of water should be frequent It is maintained at more than 3 mg/litre.
