Abstract
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.
