| Abstract: | 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. |
