Comparative taxonomy and toxicity study of freshwater species Macrobrachium rosenbergii and teleost fish in the river Ganga & River Sai

Abstract

A current study investigating the comparative taxonomy and toxicity of the prawn Macrobrachium rosenbergii and teleost fish in the River Ganga & River Sai highlight relevant information on the general biology of the giant freshwater prawn (M. rosenbergii), its aquaculture, the biodiversity of Ganga River fish, and studies on aquatic species toxicity. one would combine taxonomic information on M. rosenbergii and select teleost species with toxicity data from relevant studies on river environments. Freshwater Prawn (Macrobrachium rosenbergii): Classify it as a palaemonid freshwater prawn and note its presence in the Indo-Pacific region, including India. River Ganga and Sai existing studies on fish and prawn toxicity in these or similar river systems in India, as direct toxicity studies of M. rosenbergii alongside teleosts. Potential Pollutants Mention relevant industrial, agricultural, or municipal pollutants that could affect aquatic life in these rivers, which would be key for toxicity assessments. Species Sensitivity: Analyze the different toxicological sensitivities between the prawn and fish species under study to specific pollutants, which can differ significantly between invertebrates and vertebrates. Environmental Impact Discuss the broader implications for the biodiversity and human health in the region district the importance of understanding the ecological health of major Indian rivers like the Ganga and Sai, focusing on key aquatic species such as the giant freshwater prawn (M. rosenbergii) and native teleost fish. Detail the study's aim to compare the taxonomy and differential susceptibility to common environmental toxicants between M. rosenbergii and select teleost fish inhabiting these rivers. Briefly describe the sampling strategy, taxonomic identification of species, and the specific ecotoxicological assays that would be used. Predict findings regarding variations in physiological responses and overall tolerance to pollutants between the prawn and fish, noting potential differential vulnerability. Emphasize how these findings would contribute to better environmental monitoring, fisheries management, and conservation strategies for these vital freshwater ecosystems. The research paper focused on how various heavy metals affect a common teleost fish, Amblypharyngodon mola, and other freshwater species, a common theme in Indian studies like those found on the National Digital Library of India. Heavy metals contaminate the river, posing risks to both fish and human health, with fish acting as bio-accumulators. Studies are actively conducted to investigate the morphology and biology of various species and their potential to serve as biological indicators for metal pollution.
