On the occurrence of siphonophores in the Cochin Backwater

Rengarajan, K (1974) On the occurrence of siphonophores in the Cochin Backwater. Journal of the Marine Biological Association of India, 16 (1). pp. 280-285.



No information is available on siphonophores of the estuaries in India. The present investigation was taken up to study their occurrence and seasonal fluctuation in the Cochin Backwater, a tropical estuary. Data on salinity, temperature, zooplankton biomass and siphonophores were collected by analysing the samples obtained from 10 stations in the Cochin Backwater area between Aleppey light house (south of Cochin) and Marthomanagar (north of Cochin) during 1971 and 1972. Data reveal that siphonophores are present in the estuary, in the pre-monsoon and the post-monsoon periocfc except during, January. Analysis of data on rainfall, temperature and salinity shows that salinity has a more important role to play on the occurrence and seasonal fluctuations of the siphonophores.
