Abstract
Reproductive cycle of natural population and artificial control experiments of gonadal development by the conditions of water temperatures-feeding and starvation of Ruditapes philippinarum were investigated by histological observations. The reproductive cycle of natural population in females and males can be categorized into five successive stages; early active (February to March), late active (April to May), ripe (April to August), partially spawned (May to October), and spent-inactive stage (August to March). In the artificial control experiments, gonadal development of this species was inhibited by the low water temperature (10
자연산 바지락 (Ruditapes philippinarum) 개체군의 생식 주기와 수온-먹이섭이 및 절식조건에 따른 생식소 발달의 인위적 제어 결과를 조직학적 관찰에 의해 조사하였다. 곰소만 자연산 바지락 개체군의 생식소 발달에 따른 암수 개체의 생식주기는 초기활성기 (4-5월), 완숙기 (4-8월), 부분산란기 (5-10월), 퇴화 및 비활성기 (8-3월)의 연속적인 5단계로 구분할 수 있었다. 수온에 따른 생식소 발달의 인위적 제어 실험에서, 바지락은 저수온 (10
