The Deleterious Effect of Aldehydes Produced by Marine Microalgae on the Reproduction of Calanus sinicus

2 algae - Chaetoceros muelleri (CM) and Scrippsiella trochoidea (ST) were investigated for the influence on the reproduction of Calanus sinicus. HS-SPME/GC-MS was developed for the analysis of aldehydes produced by phytoplankton. The results showed that, compared with ST, CM induced inhibitory effects on female survival, egg production and egg hatching for Calanus sinicus. By the analysis of aldehydes, 5 kinds of aldehydes were detected in CM, whereas only 2 kinds of aldehydes ST contained. Furthermore, the total content of aldehydes in Chaetoceros muelleri (397.86 10^-3μg /g) was significantly higher than that in Scrippsiella trochoidea (82.84 10^-3μg /g). Therefore, the evidence indicated that aldehydes produced by Chaetoceros muelleri caused potential negative effect on the reproduction of Calanus sinicus.
