Abstract

1. Infectious glochidia are attached only on the young fish of Zacco platypus which ranged from 2 to 4 cm in total body length. 2. The attachment of the glochidia on the fish was found at the beginning of April. 3. The glochidia per infectious fish are shown to be 1.6 in average number. 4. the glochidia were dropped from the infectious fish completely from late April through early May. 5. Most glochidia released from mother shell are attached on the fins on infectious fish, and also on the eyes, nose, mouth and gill. 6. The largest number of the glochidia was attached on the caudal fins of infectious fish, and the next was pectoral fins.

1. Lamprotula coreana 가 棲息하는 現地에서는 體長 2-4cm 되는 피라미의 稚魚에서 만 本種의 幼生이 附着하고 있는 것을 觀察할 수 있었다. 2. 本種의 幼生의 魚體附着은 4月初에 이루어짐을 알았다. 3. 피라미의 個體當 幼生附着數는 1.6이었다. 4. 附着된 幼生은 4月末에서 5月初에 걸쳐서 完全히 脫落되었다. 5. 放出된 幼生은 大部分이 지느러미에 附着디며 少數는 눈, 코, 입, 아가미 等에도 附着한다는 事實을 밝혔다. 6. 幼生이 가장 많이 붙는 部位눈 魚體의 꼬리지느러미이었고 다음이 가슴지느러미이었다.
