Abstract

The present studies of phytoplankton algal species belonging to genra. Anabaenopsis, Anbaena and Nostoc of family Nostocaceae along with physico chemical analysis from Chakan lake, district, Dadu, Sindh, Pakistan. Ecological studies of phytoplankton in saline water was done from December 2013 to November 2014.

Introduction

Chakan Lake is the largest and oldest salt water lake in Sindh, it is located Palh village 26°57′3394N 67°51′0610E nearly 25 km in north from Dadu city. The lake covers an area of 142 meters. The lake collects water from numerous small agricultural channels from (Dadu canal). It was nearly 12 meters deep in the beginning but continuously silting and deposition decaying has decreased the depth up to 5 to 7 meters. The importance of ecological studies of these organisms can be released from the fact that Planktonic species are important component of aquatic environment they make significant contribution to the ecological condition of these water [1]. Phytoplankton species are essential components of aquatic ecosystems especially for productivity of water bodies hence they play role of producers in aquatic ecosystem. Fish population is dependent on the species directly either indirectly [2]. Species of Phytoplankton (Nostocaceal) have been studied by many authors from various area of Pakistan [3-5]. Present study of Phytoplankton (Nostocaceae) was made from three station of Chakhan lake.

Materials And Methods

Chakhan lake, Dadu, Sindh was surveyed from December 2013 to November 2014 from three places (Tables 1-6). The collection and studies material was the same as described with previously the phytoplankton (Nosttocaceae) samples were stored in plastic bottles, and preserved 4% formalumic. Identification of phytoplankton was made by literatix [6]. The algae were classified [2].
