摘要
温室无沙养鳖法是对传统的有沙养鳖法进行重大改革，其主要特点是能克服底质和池水极易污染的问题，从而改善栖息环境，提高放养密度。“人工鳖巢”是一种较理想的栖息隐蔽物，用它替代河沙，排污比较彻底、洗池省工省时。试验证明，无沙养鳖法具有高产、优质、低成本，以及观察检查、饲养管理和干池捕鳖均很方便等优点。这种新工艺对稚鳖和幼鳖都适用，但它是一项综合性的养殖技术，除用“人工鳖巢”替代河沙作鳖的栖息隐蔽物外，在饲养管理方面还须采取相应的配套技术措施。
Softshelled turtle sandless rearing in greenhouse is a great change to the traditional rearing method with sand. It helps to resolve the problem of substrate and water getting easily polluted so that the rearing environment could be further improved and rearing density increased. “ Artificial Turtle Nest ” is an ideal shelter for the turtle, with which the sewages could be discharged more completely and manpower and time for pond cleaning could be saved. Experiments show that the new method has the advantages of high-yield, good quality, low cost and convenient in observing, rearing management and catching. The new method is applicable to both young and juvenile turtles. However, rearing turtle without sand is a synthetic technique. Apart from using “ artificial turtle nest ” to replace sand for turtle rearing, correspondent technical measures should also be taken in rearing and management.
