The Study and Analysis on Seasonal Variations of Nano and Microalgae in Stomach Contents of Venerupis philippinarum in Xiangshan Bay

Abstract:

In this study, we analyzed the compositions and seasonal variations of nanoand microalgae in stomach contents of Venerupis philippinarum in Xiangshan Bay. 132 species of nanoand microalgae were identified in Venerupis philippinarum stomach contents in four seasons. The nanoand microalgae in Venerupis philippinarum ingested were changed with variations of seasons. The nanoand microalgae ingested in spring and summer were larger than those ingested in autumn and winter, while the species number ingested in spring were more than those ingested in summer, autumn or winter. The nanoalgae in Venerupis philippinarum stomach contents were smaller than 20 micrometer and the dominant species were Skeletonema costatum, Navicula perminuta, Paralia sulcata, Leptocylindrus minimus, Cylotella spp., Nitzschia spp., etc. The microalgae were larger than 20 micrometers and the dominant species were Coscinodiscus jonesianus.
