(Society of Fisheries Technologists (India) Cochin, 1990) NAIK, U. G; REDDY, C. R; SHETTY, D. C; NEELAKANTAN, B
The results obtained from the investigations on the abundance and seasonal Huctuations of plar k‘on and hydrographic condiiions of fishing areas cf Karwar waters are pres :nted and discussed. The displacement volume of plankton (9.2~29.6 ml/m’) showed two peaks one in November-December and other in February-March. Among the phytoplankton, the diatoms constitute the major part of the total phytoplankton with dominant species like Fragillaria, Coscinodiscus, Thalassiothrix, Chaetoceros, Nirzschina, Rhizosolenia and Biddulphia whereas among the zoopl;nktons, the dominant groups mainly comprised of` copepods, decapod larvae, chaetognaths and medusae. The observed valuis ofhydrographic parameter showed a birnodil peak. A correlation between plankton abundance and fishery has been attempted in this paper.
