Abstract
The invention provides a method for ecologically breeding river crabs in a southern hilly land slope, and relates to the field of aquaculture. The method comprises the following steps that a black carp pool, a duck pool and a river crab pool are arranged in the slope; the black carp pool is used for breeding black carps and changing the weak acidity of water; in addition, faeces of the black carps fall into the river crab pool through a water suction pipe, a flood control pipe and a flow guide pipe to provide certain nutrients for the growth of the river crabs; meanwhile, the stream is introduced; the stream supplements fresh air when flowing through the black carp pool to fall down into the river crab pool; the artificial oxygen supplementation is not needed; a great number of river crabs can be bred in the slope; faeces of ducks bred in the duck pool fall into the duck pool through drain holes formed in a bottom plate of a duck house; the nutrients are provided for duckweeds bred in the duck pool; the duckweeds flow into the next stage of the river crab pool through a duckweed pipe; the nutrients are provided for the river crabs; the PH of the river crab pool is controlled.
Description
Technical field
The present invention relates to aquaculture field, be specifically related to the side of hillside fields, a kind of southern hills area ecologic breeding crab
Method.
Background technology
The carapace that crab also makes " Eriocheir sinensis " and " eriocheir sinensis ", head and chest be combined into is square circular, and quality is hard.Body
Body front end has a pair, and side has two and lives the hardest sharp Eriocheir sinensis tooth, the Yu Jiang that often lives in caves, river, the mud bank of lakes and marhshes, night
Dynamic, with fish, shrimp, spoil and corn for food, annual autumn, normal migration was laid eggs to the river mouth gone to sea, and Second Year 3～May incubate
Changing, after developing into children Eriocheir sinensis, then river of tracing back is Fresh & Tender in Texture, is the food simply being loved by the people.
Southern hills area abundant water, but level land is less, along with growth and the development of society of Chinese population, more
Coming the most level lands to be used for building house and factory, along with the scope of expropriation of land is increasingly wider, agricultural land gradually decreases, crab
Production range be also gradually reduced；Therefore it provides a kind of new breeding way produces high-quality crab replaces an original part
Extremely the most urgent the crab of plain lakes cultivation.
Crab generally prefers that and lives in weakly alkaline waters, but streams, hillside fields is owing to being subject to agricultural and industrial pollution relatively
Few, the content of streams humus layer organic acid in woods increases, and therefore streams, hillside fields is typically faintly acid or neutrality.
Summary of the invention
In view of the foregoing, it is necessary to the method providing hillside fields, a kind of southern hills area ecologic breeding crab, it is not only
Hillside fields can be utilized to carry out cultivating river crab, overcome the faintly acid in streams, hillside fields, and the most nuisanceless.
