Abstract

This paper deals preliminary study of plankton in Sonmiani, Balochistan waters. Copepods were the highest dominant group, about 23.68 % of total catch. Next highly occurring groups were Ceratium spp . (dinoflagellates) and eggs were about 20.36 % of each. Diatoms found only 2% while chaetoganatha and jelly fish were found markedly very low in percentage (0.69%) during present investigations. According to Simpson diversity index site 1 was less in richness and site 3 was much higher in richness.

Highlights

  • Plankton is various small drifting plants, animals and microorganism that inhabit bodies of water

  • Coast of Baluchistan located on northern Arabian Sea comprising 70% shoreline, out of total coast of Pakistan

  • Numerous studies have shown a strong relationship between larval fish survival and the timing and production of their food

Summary

Introduction

Plankton is various small drifting plants, animals and microorganism that inhabit bodies of water. Plankton drives the “biological pump”, processes by which the ocean ecosystem transports carbon from the surface to the ocean’s depths. Coast of Baluchistan located on northern Arabian Sea comprising 70% shoreline, out of total coast of Pakistan. Sonmiani Beach is located in the Lasbela District of the Balochistan state of Pakistan. It is located in Sonmiani Bay. Planktons are diverse group of organisms that live in the water column and are incapable of swimming against water currents. Life in the water and specially in the sea has been broadly classified into three groups, viz., the plankton, the nekton and the benthos, which are floating, swimming and creeping organisms respectively
