Fisheries oceanography- Established links in the eastern Arabian Sea

Fish distribution along the western Indian coastal waters indicates a bias for pelagicplanktivores to the southern coast and carnivores to the northern coast. Southwest coast of India is an upwelling zone rich in phytoplankton dominated by diatoms during summer monsoon. The landing centre observation data since 1985 clearly indicate a dominance of Indian oil sardine (Sardinella longiceps) in this upwelling zone. The physiological activity of the fish is also tuned to the arrival of summer monsoon
