Suseelan, C and Pillai, P P and Pillai, M Ayyappan and Nair, K Ramakrishnan (1985) Some observations on the trend of zooplankton and Its probable influence on local pelagic fisheries at Colachel during 1973-74. Indian Journal of Fisheries, 32 (3). pp. 375-386.
The zooplankton standing crop showed three peaks of abundance, in March, September and December, the first two peaks during the periods of high salinity. In the order of abundance, the forms which constituted the bulk of the plankton were copepods, cladocerans, cirrepede larvae, Lucifer, chaetognaths and appendicularians. The copepod distribution was found to have characters common both to that of the adjacent coastal waters of Bay of Bengal on the southeast coast and to that of the Arabian sea on the southwest coast. The peak occurrence of cladocerans during May-July was followed by the appearance of juvenile mackerels in early August. Pelagic fish catch, consisting mostly of anchovies and lesser sardines, showed clear peaks, closely following the primary and secondary peaks of plankton. The peak occurrence of anchovies during September-October seems to be in prey-predator relationship with ribbonfish, the peak of which followed closely.
