A Preliminary Study on Phytoplankton in Fresh Water-Lake of Gogi, Yadgir District, Karnataka

Abstract

ABSTRACT:The present study was conducted in a semi arid region of Karnataka. The study discusses the phytoplankton diversity of the Gogi lake ecosystem. A standard methodology was followed in conducting to complete this study and samples were collected at different points from the lake ecosystem located at the core area of the proposed uranium mining site. Through a field survey, twenty one species of phytoplankton were recorded coming under four classes viz.,

Conditions Of Phytoplankton Community Structure In Lake Toba Ajibata, Toba Samosir Regency

“…Phytoplankton are producers that act as the basis of the food chain and food source for aquatic animals. Phytoplankton are the primary producers of food in every aquatic ecosystem, serve as a food source for fish and most other aquatic organisms [1]. According to [2], the phytoplankton community has an important ecological role in aquatic ecosystems as the main producer and is the basis of the aquatic food chain to support the community of aquatic organisms.Lake Toba is at an altitude of 905 above sea level and has a water area of 1,124 km², water volume of 256.2 x 109 m³, and an average depth of 228 m [3].…”

Occurrence and diversity of microalgae in phytoplankton collected from freshwater community ponds of Hooghly District, West Bengal, India

“…Considering these aspects extensive studies have been carried out in India on the microalgae occurring as phytoplankton. These include seasonal distribution (2)(3)(4), diversity of fresh water algae (4,(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) physico-chemical parameters of aquatic system (3,4,(15)(16)(17) and algal blooms (4,18). These works have been carried out with respect to both lotic and lentic ecosystems.…”
