Abstract

This study was conducted in 2020 to find out the total identified fresh/river water zooplankton in Bangladesh. This review was carried out based on the secondary data. Data were collected from different published journals and websites. Images of every species were collected from different websites since their image cannot be download from PDF and some of the publications only stated name. In the present study, a total of 260 zooplankton species were recorded in fresh/river water. Few species were identified in the larvae and egg stage. Zooplankton is an important part of the aquatic ecosystem that formulate the food chain and food web. There is very limited research on freshwater zooplankton in Bangladesh. Most of the study identified up to the Order level and unpublished. The findings of the present study suggested that it is very necessary to identify the freshwater zooplankton in species-level with a very clear image. This will be a great resource for the conservation of the river or freshwater ecosystem.
