초록

We investigated the degree of obesity, histological development stages of gonads and sexual maturation induction
rates of comb pen shell, Atrina pectinata, per the type of micro-algae supplied. Terms of maturation by singular or
mixed supply of microalgae, it was found that maturation of the female was the quickest at 60.0% by the
Tetraselmis tetrathele (Tet). experiment group followed by 57.1% by the Chlorella ellipsoidea (Chl). experiment
group and 16.7% by the Phaeodactylum tricornutum (Pha). experiment group. However, there were no significant
differences between Tet. experiment group and Chl. experiment group. As for the male, maturation was the
quickest at 60.0% by the Tet. experiment group followed by 16.7% by the Chl. experiment group and 14.3% by the
Pha. experiment group. In light of these results, Tet. is concluded to be a very useful feed organism in breeding the
mother comb pen shells. Upon completion of the experiment, the sexual maturation induction rate for the female
was found to be the highest at 82.0% in the Tet. experiment group followed by 72.0% by the Chl. experiment
group, 64.0% by the Pha. experiment group and 58.0% by the mixed micro-algae experiment group. During the
period of experiment, the survival rate was the highest at 94.4% by the mixed micro-algae experiment group
followed by 90.0% by the Pha. experiment group, 83.1% by the Tet. experiment group and 78.8% by the Chl.
experiment group.
