재첩, Corbicula fluminea의 저질선택성 및 잠입율

Sediment preference and burrowing rate of marsh clam, Corbicula fluminea according to the shell lengt

In order to investigate the effect of sediment preference of the marsh clam, Corbicula fluminea, and burrowing rate on growth the shell(spat and adult) reared in the tank of the laboratory culture different size(below 0.10 ㎜, 0.11~0.50 ㎜, 0.51~1.00㎜, 1.01~2.00 ㎜, 2.01~5.00 ㎜ and blank). The higest value in both sediment preference and survival rate of C. fluminea were shown at fine sand below 0.10 ㎜ in the mean diameter. In the burrowing rate experiment to the sediment depth, spat and adult of C. fluminea were mostly distributed from 5 ㎝ to 10 ㎝.
