摘　　要：研究了在实验室内人工洞穴对克氏原螯虾存活率的影响 ,并在洞穴的质地、长度对入穴率的影响做了比较实验。研究结果表明 :有人工洞穴比自然状态下 ,螯虾的存活率提高了 6 4倍 ;螯虾更适应穴长较长的、避光。The effects of cave sizes and patterns on the artificial breeding of crayfish, Procambarus clarkii, was studied in laboratory. The results showed that the crayfish had survival rates 6.4 times higher in the ponds with artificial caves than that in the ponds without artificial caves. The crayfish selected the caves which were long, penetrated sunlight and freely ventilative.
