Inhibition of Population Growth in the Copepod Calanus sinicus during Diatom Bloom

Abstract:

Article Preview

Field evidence is presented showing that egg production rate and hatching success in the copepod Calanus sinicus were greatly modified during a major late-winter diatom blooms in the Jiaozhou Bay (Yellow Sea). The diatom species composition in this period had shifted to a dominance of Skeletonema costatum and Thalassiosira sp, and comprised about 65% of phytoplankton population among all six sampling stations. Calanus sinicus were examined to determine the effects of the diatom bloom on reproduction and recruitment. The results of egg production rate and hatching success were significantly decreased with the increase of chlorophyll a concentration, indicating that diatom bloom induced negative effect on the copepods population recruitment.
