The invention utilizes the annular ditch of the blue crab culture pond, the bottom of the annular ditch is deepest from the water surface, and the influence of the water temperature along with the weather temperature is small; because the binding belts only bind the chelae, the green crab cream crabs automatically migrate to the deep part of the circular ditch during cooling, and the cold tide frostbite or the freeze death of the green crabs is avoided; when the binding belt is recaptured, only the binding belt needs to be recycled, and the recapture is convenient.
Description
Technical Field
The invention belongs to the technical field of blue crab breeding, and particularly relates to a suspended breeding-based method for temporarily breeding blue crab cream crabs in winter.
Background
Scylla paramamosain (Scylla paramamosain), commonly called blue crab, is delicious in taste and rich in nutrition, is a famous and precious marine crab culture variety with important economic value in China, and is also a marine culture crab with the largest yield in China. In recent years, the green crab breeding industry in China is developed rapidly, the green crab breeding yield is 15.8 million tons, the yield value is as high as 260 hundred million, the green crab breeding method becomes the agricultural support industry in various places along the coast in China, and great contribution is made to increasing income of farmers.
Under the natural condition, when the water temperature of the blue crabs is reduced to below 15 ℃ in winter, the blue crabs dig holes to live through the winter, so that farmers are difficult to catch the blue crabs, and local blue crabs cannot supply markets with vigorous demands during the spring festival. Therefore, farmers generally gradually catch and market water when the water temperature is higher in 10-11 months, but the harvesting time of the blue crabs is too concentrated, the sale price is lower, the profit margin of the farmers is seriously compressed, and the breeding benefit is seriously influenced.
By temporarily breeding the blue crabs in winter, avoiding the period of coming into the market in autumn in a large amount, and selling the blue crabs before the spring festival, the problem of low selling price in autumn can be relieved, the economic benefit brought by peak-staggering selling can be increased, and the method has important significance for promoting the income increase of farmers. The temporary culture of the green crab commodity crabs, particularly the cream crabs, has the characteristics of short time and great benefit. However, the temporary blue crab culture method adopted at present generally puts the blue crabs in a cement pool for temporary culture management, and is generally only suitable for temporary culture for about 1 month, the time is long, and the survival rate is reduced even the temporary culture can not be carried out until the spring festival. Other methods such as temporary rearing methods using rearing cages, crab apartments, crab boxes and the like are greatly limited by temporary rearing fields, the rearing area is limited, the temporary rearing cost is high, or the method has the disadvantage of poor resistance to sudden weather changes, and the survival rate is difficult to guarantee. Therefore, how to improve the winter temporary culture method of the green crab cream crabs and improve the temporary culture survival rate and the economic benefit becomes a key problem which needs to be solved urgently.
