Abstract

To investigate the factors controlling the spring population of Acartia hongi, egg production, hatching time of egg and predation pressure were measured. Egg production was maintained the superior position between winter and spring. Egg production was positively correlated with not only water temperature when water temperature was below $7^{\circ}C$ but also chlorophyll-a concentration when it was from $7^{\circ}C$ to $21^{\circ}C$. A regressive equation of development time$(D_e,\;day)$ of eggs derived from water temperature$(T,\;^{\circ}C)$ was obtained as $D_e=18.9(T-0.4)^{-1.0}$, showing longer development time at water temperature below $5^{\circ}C$. In Cross Correlation Analysis(CCA) to examine the time-lag relationship among abundances of developmental stages of A. hongi, egg production rate calculated by multiplying population egg production rate by hatching time showed more significant correlation with nauplii abundance than population egg production rate. Therefore, it suggests that hatching time is also recognized by a factor controlling formation of population and especially, in winter, high abundance of egg derived from high daily egg production rate and delayed hatch by low water temperature become the origin of initial spring population of nauplii. Egg predation by Noctiluca scintillans, suggesting a negative factor in formation of A. hongi spring population, was observed. During spring, A. hongi eggs were found in $2.9\sim21.1%$ of individuals of N. scintillans. It was deduced that $1.2\sim49.5%$ of the eggs produced by A. hongi was preyed on by N. scintillans. In conclusion, the factors controlling spring population of A. hongi were regarded as high egg production by winter generation, the delayed development time of egg by low temperature, and egg predation of N. scintillans.

본 연구에서 Acartia hongi 춘계 개체군 형성의 영향 요인을 파악하기 위해 알 생산, 알 부화시간, 알 포식에 관한 조사가 수행되었다. 알 생산은 동계부터 춘계 사이에 높은 수준을 유지하였다. 알 생산은 수온이 $7^{\circ}C$ 이하일 때 수온 증가에 따라 증가하였으며, 수온 $7\sim21^{\circ}C$ 사이에서는 클로로필 a 농도와 유의한 양의 상관관계를 나타냈다. 알부화 시간$(D_e,\;day)$은 수온$(T,\;^{\circ}C)$에 따라 다음과 같은 회귀식이 얻어졌다. $D_e=18.9(T-0.4)^{-1.0}$ 알 부화 시간은 수온 $5^{\circ}C$ 이하에서 급격히 길어지는 경향을 보였다. 시간차에 따른 A. hongi의 성장 단계별 현존량 변화의 상관관계를 보기 위해 교차상관분석(CCA)을 수행하였다. 개체군 알 생산율에 부화시간을 고려한 알 생산은 개체군 알 생산을 보다 노플리우스 현존량과 유의한 상관관계를 보였다. 이는 부화 시간도 개체군 형성에 영향 요인이 됨을 의미하며, 특히 동계에 높은 일간 알 생산율과 저수온에 대한 부화 지연으로 야기된 높은 알 현존량은 춘계 초기 노플리우스 개체군의 기원이 될 것으로 본다. 춘계 개체군 형성의 부정적인 요인으로 Noctiluca scintillans의 알 포식이 관찰되었다 N. scintillans전체 개체수의 $2.9\sim21.1%$에서 A. hongi 알이 관찰되었으며, 이는 A. hongi 개체군 알 생산율의 $1.2\sim49.5%$에 해당한다. 결론적으로 A. hongi춘계 개체군 형성에 영향 요인으로 동계 세대에 의한 지속적으로 높은 알 생산, 저수온에 따른 부화 지연 그리고 N. scintillans의 알 포식 등이 고려된다.
