Hydrobiology and phytoplankton population in Sona river of Siwan District in North Bihar

The hydrobiological parameters influencing indirectly to the trophic composition in any water reservoirs. A hydrobiological study conducted in three sites of Sona river in Siwan district of Bihar showed that water parameters are within the permissible level in water quality standard for fishery. The water quality parameters were estimated by standard methods. The micronutrients showed higher iron content in study sites. This study concludes aquaculture potential in small rivers and its conservation is essential.
