The distribution and abundance of the gelatinous zooplankton
namely hydromedusae, scyphomedusae, siphonophore, ctenophore, salps, doliolids,
appendicularians and chaetognaths were investigated in two seasons at seven
stations in East Tamil Nadu coast, India. The occurrences of gelatinous zooplankton
were observed to be more in summer than in winter. However, the composition
of different species in each group varied from all the stations and seasons.
Apart from the individual variation in seasonal distribution, most of the species
appeared to be cosmopolitan in the Indian waters. A total of 34 species from
summer and 17 species from winter were recorded during the present study. The
hydromedusae were dominant in both the seasons of the study period. Ephyrae
of the scyphomedusae were also noticed in both the seasons.
