Abstract

A rotifer starin has been isolated from tide pools located near Sogwipo, Cheju Island and the effects of environmental factors (water temperature and salinity) and clonal differences have been examined with regard to size variation and cyclomorphosis. Adult female rotifers varied from 141.61 to $173.97 \mutextrm{m}$ in their mean lorica length under different rearing conditions in the laboratory and also had pointed anterior spines . Thus, this strain was classified as Brachionus rotundiformes. Mean lorica length tended to be smaller as rearing temperature increased although there were some exceptions. Statistical analysis indicated that lorica length was largely influenced by both clonal differences and rearing temperatures although the former as a genetic factor affected lorica length a little more than the latter did ; overall effect of salinity on lorica length was not statistically signicicant; furthermore, cyclomorphosis was also largely influenced by both clonal differences and rearing temperatures, but clonal differences as a genetic factor affected rotifer cyclomorphosis much more than temperature did.
