Abstract
The effects of aldehydes produced by two algae Skeletonema costatum and Prorocentrum micans on reproduction of Calanus sinicus were investigated in laboratory. Aldehydes produced by these two algae were analyzed qualitatively and quantitatively by HS-SPME/GC-MS method. Compared with P. micans,S. costatum showed negative effects on female survival,egg production and egg hatching of C. sinicus. Six kinds of aldehydes were detected in S. costatum,while only 2 kinds were detected in P. micans. The content of any single aldehyde or total aldehydes in S. costatum were significantly higher than those in P. micans,indicating that the aldehydes produced by diatom could cause potential negative effects on the reproduction and survival of C. sinicus.
