Abstract
The invention discloses a kind of cultural method for improving river crab meat, comprise the following steps：S1, pond treatment：Pond water is allowed to dry, applies pulverized limestone, is exposed to the sun, lays loam, water filling；S2, juvenile crab are launched：Juvenile crab is sterilized, launched after adapting to pond water temperature；S3, feed management：Feed man-made feeds 23 times daily；S4, water quality management：Water colour and transparency are observed, changes water in good time, clears up pond debris in time；S5, capture.A kind of cultural method for improving river crab meat proposed by the present invention, by Optimal culture technique, resource utilization is high, and quantity of exchanged water is small, and water body capacity of self-regulation is strong, and the river crab incidence of disease is low, and meat is good, and the culture-cycle is short, is favorably improved the economic benefit of culture of Chinese mitten crab.
Description
Technical field
The present invention relates to technical field of aquaculture, more particularly to a kind of cultural method for improving river crab meat.
Background technology
River crab often lives in caves the mud banks of Yu Jiang, river, lakes and marhshes, nocturnalism, using fish, shrimp, spoil and cereal as food, every year
Autumn normal migration is to the river mouth spawning gone to sea, hatching in 3~May of Second Year, and after developing into young crab, then river of tracing back is Fresh ＆ Tender in Texture, is
The food simply being loved by people.River crab is Fresh ＆ Tender in Texture, nutritious, has and dissipates blood, reunion of fractured tendons and bones reconciliation knee poison and other effects,
It is loved by consumers.Because wild river crab captures difficulty, quantity is few, can not meet the market demand, frequently with artificial farming.Mesh
Preceding artificial farming has that water body capacity of self-regulation is poor, and quantity of exchanged water is big, and resource utilization is low, and the river crab incidence of disease is high, and meat is poor, raw
Long period is longer, influences the economic benefit of culture of Chinese mitten crab.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of cultural method for improving river crab meat, leads to
Optimal culture technique is crossed, resource utilization is high, and quantity of exchanged water is small, and water body capacity of self-regulation is strong, and the river crab incidence of disease is low, and meat is good,
Culture-cycle is short, is favorably improved the economic benefit of culture of Chinese mitten crab.
A kind of cultural method for improving river crab meat proposed by the present invention, comprises the following steps：
S1, pond treatment：Pond water is allowed to dry, applies pulverized limestone, is exposed to the sun, lays loam, water filling；
S2, juvenile crab are launched：Juvenile crab is sterilized, launched after adapting to pond water temperature；
S3, feed management：Feed man-made feeds 2-3 times daily；
S4, water quality management：Water colour and transparency are observed, changes water in good time, clears up pond debris in time；
