Abstract
The invention discloses a river crab and yellow catfish polyculture method. A river crab culture pond with the pond area ranging from 10 mu to 20 mu is selected, the pond depth ranges from 1.2 m to 2.5 m, an oxygenation facility is matched, sterilization is conducted with quicklime of 10-20 kg for each mu 30 days before fry is cast, and fermented and thorough decomposed organic fertilizer of 50-100 kg each mu is cast one week later; the yellow catfish fry is cast around the Tomb-sweeping Day, the specification of the fry ranges from 10 g to 30 g, and 2.5 kg of fry is cast each mu. Due to the fact that the yellow catfish is omnivorous fish, the fry is small in appetite, and pellet feed and small trash fish are cast in the crab pond, the remaining feed of river crabs is enough to feed the yellow catfish, and feed does not need to be additionally cast. After August, along with the growth of the yellow catfish and the increase of the appetite of the yellow cast fish, feed special for the yellow catfish needs to be supplemented, the daily feed cast amount is 20-30 kg each mu, and the feed is cast two times in the morning and at the nightfall. The river crab and yellow catfish polyculture method has the advantages that the culture water body is saved, the culture yield is increased, and the feed is saved.
Description
Technical field
The present invention relates to a kind of cultural method of aquatic products, be specifically related to a kind of river crab yellow cartfish polyculture method.
Background technology
Because the bait of river crab and yellow cartfish is comparatively close, so traditional river crab and yellow cartfish are all generally take monoculture pattern.Along with the atrophy day by day of breeding water body resource, and seriously constrain the development of freshwater aquaculture industry, meanwhile, monoculture per unit area yield yields poorly, and can not utilize breeding water body effective and reasonablely.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of river crab yellow cartfish polyculture method.
Technical problem to be solved by this invention is realized by following technical scheme.The present invention is a kind of river crab yellow cartfish polyculture method, be characterized in: selection pond area is the river crab culture pond of 10-20 mu, the dark 1.2-2.5 rice in pond, and supporting oxygenation is implemented, within first 30 days, carry out disinfection with quicklime every mu 10-20 kilogram at throwing seedling, the fertilizer of fermentation maturity is dropped into, every mu of 50-100 kilogram after one week.To throw in yellow cartfish seedling before and after the Ching Ming Festival, the specification of seedling is 10-30 gram, throws in 2.5 kilograms for every mu.Because yellow cartfish is ominivore-fish, during seedling, appetite is little, and crab pond is all throw something and feed pellet and small fish, and river crab eats remaining feed, and just enough yellow cartfishs are edible, do not need to throw something and feed in addition feed again.After August, along with the raising of the growing up of yellow cartfish, appetite, need supplementary yellow cartfish special feed, every day, feedstuff feeding amount was every mu of 20-30 kilogram, and point morning and 2 throwings are at dusk raised.
Compared with prior art, the inventive method has advantages such as saving breeding water body, raising cultured output and saving feed.
Embodiment
Below further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
Embodiment 1, a kind of river crab yellow cartfish polyculture method, selection pond area is the river crab culture pond of 10-20 mu, the dark 1.2-2.5 rice in pond, and supporting oxygenation is implemented, and within first 30 days, carries out disinfection with quicklime every mu 10-20 kilogram at throwing seedling, the fertilizer of fermentation maturity is dropped into, every mu of 50-100 kilogram after one week.To throw in yellow cartfish seedling before and after the Ching Ming Festival, the specification of seedling is 10-30 gram, throws in 2.5 kilograms for every mu.Because yellow cartfish is ominivore-fish, during seedling, appetite is little, and crab pond is all throw something and feed pellet and small fish, and river crab eats remaining feed, and just enough yellow cartfishs are edible, do not need to throw something and feed in addition feed again.After August, along with the raising of the growing up of yellow cartfish, appetite, need supplementary yellow cartfish special feed, every day, feedstuff feeding amount was every mu of 20-30 kilogram, and point morning and 2 throwings are at dusk raised.
Claims (4)
1. a river crab yellow cartfish polyculture method, is characterized in that every, pond area 10-20 mu, the dark 1.2-2.5 rice in pond.
2. a river crab yellow cartfish polyculture method, is characterized in that pond carries out disinfection with quicklime every mu 10-20 kilogram at throwing seedling for first 30 days, drops into the fertilizer of fermentation maturity, every mu of 50-100 kilogram after one week.
3. a river crab yellow cartfish polyculture method, is characterized in that nursery puts the time in a suitable place to breed before and after the Ching Ming Festival, and the specification of seedling is 10-30 gram, throws in 2.5 kilograms for every mu.
4. a river crab yellow cartfish polyculture method, after it is characterized in that August, needs supplementary yellow cartfish special feed, and every day, feedstuff feeding amount was every mu of 20-30 kilogram, and point morning and 2 throwings are at dusk raised.
