Description
Technical Field
The utility model relates to a breed the crab and use the facility, especially relate to a rice field is bred detain crab with preventing escaping device belongs to aquatic products ecological health and breeds facility construction technical field.
Background
With the further improvement of living standard, people have more and more demands on green, healthy and organic foods. In recent years, the agricultural industry structure of China is adjusted rapidly, and the comprehensive planting and breeding of the rice field becomes an agricultural production mode for improving the utilization efficiency of farmland space, providing high-quality agricultural products and increasing the income of farmers, wherein the crab cultivation in the rice field is a common comprehensive planting and breeding mode of the rice field. The river crabs are natural climbing highhands and can cross a common escape-proof net by means of strong footage of the river crabs, so that the escape of the river crabs often occurs in the conventional river crab culture production, and the direct loss of the culture production is caused; because the vitality of the larval crabs is limited, a large number of larval crabs are usually exposed to the sun and died around the escape-proof wall in the escape process; in addition, enemy organisms such as mice and the like in the culture area pass through the escape-proof net to influence the culture condition of the crabs. In the mode conversion process from a common rice field to a rice field crab culture mode, how to quickly and effectively establish an anti-escape facility, ensure the safety of a culture area, reduce the escape of river crabs, realize the timely rescue of escape crabs and improve the recapture rate is one of the problems which need to be concerned in the comprehensive rice field crab culture mode popularization.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a detain crab with preventing escaping facility is bred in rice field, this facility construction is convenient quick, prevents escaping effectually, can in time rescue the detain crab of preparing to escape, the management is bred to the convenience.
