Use of benthic macroinvertebrates has been in vogue as indicator organisms for water quality monitoring since long. Traditional methods of water quality monitoring incorporate mostly monitoring of physicochemical parameters. However, it is the biomonitoring studies that could help in more accurate water quality monitoring. Due to anthropogenic impact at water sources, integrated water quality monitoring has become a necessity. An integrated study comprising physicochemical parameters and biomonitoring using benthic macroinvertebrates was carried out at six sites along the Mahi river basin, the command area of which has witnessed tremendous economic and cultural progress over a period of time. Diversity Score and Saprobic Score were calculated, and Water Quality Class was determined as per Biological Monitoring Working Party score given by Central Pollution Control Board and results in moderate pollution at all locations, whereas Water Quality Class as per ISI-IS 2296–1982 at M-1, M-4, M-7 and M-12 shows slight pollution. Jaccard’s similarity index compared the biodiversity of benthic macroinvertebrates at all the sites from upstream to downstream locations. It was maximum, i.e., 52.94% between the locations at M-4 and M-7. Species richness (S) has also been monitored at the said locations. The Diversity Score 0.83 is maximum at the Galteshwar (M-12) location of the Mahi river, which indicates that the location was the most ecologically diverse region among all.

底栖大型无脊椎动物对马希河水质的综合监测及不同河段生物多样性的比较

长期以来,使用底栖大型无脊椎动物作为水质监测的指示生物一直很流行。传统的水质监测方法主要包括物理化学参数的监测。然而,生物监测研究有助于更准确地监测水质。由于水源的人为影响,综合水质监测已成为必要。在马希河流域沿线的六个地点进行了一项包括物理化学参数和使用底栖大型无脊椎动物进行生物监测的综合研究,其指挥区在一段时间内见证了巨大的经济和文化进步。计算多样性分数和腐烂分数,和水质等级是根据中央污染控制委员会给出的生物监测工作组评分确定的,并导致所有地点的中等污染,而水质等级根据 ISI-IS 2296-1982 在 M-1、M-4、M -7 和 M-12 显示轻微污染。Jaccard 的相似性指数比较了从上游到下游所有地点的底栖大型无脊椎动物的生物多样性。它是最大值,即 M-4 和 M-7 位置之间的 52.94%。在上述地点也监测了物种丰富度 (S)。多样性得分 0.83 在 Mahi 河的 Galteshwar (M-12) 位置最高,这表明该位置是所有地区中生态最多样化的地区。而根据 ISI-IS 2296–1982 中 M-1、M-4、M-7 和 M-12 的水质等级显示轻微污染。Jaccard 的相似性指数比较了从上游到下游所有地点的底栖大型无脊椎动物的生物多样性。它是最大值,即 M-4 和 M-7 位置之间的 52.94%。在上述地点也监测了物种丰富度 (S)。多样性得分 0.83 在 Mahi 河的 Galteshwar (M-12) 位置最高,这表明该位置是所有地区中生态最多样化的地区。而根据 ISI-IS 2296–1982 中 M-1、M-4、M-7 和 M-12 的水质等级显示轻微污染。Jaccard 的相似性指数比较了从上游到下游所有地点的底栖大型无脊椎动物的生物多样性。它是最大值,即 M-4 和 M-7 位置之间的 52.94%。在上述地点也监测了物种丰富度 (S)。多样性得分 0.83 在 Mahi 河的 Galteshwar (M-12) 位置最高,这表明该位置是所有地区中生态最多样化的地区。在上述地点也监测了物种丰富度 (S)。多样性得分 0.83 在 Mahi 河的 Galteshwar (M-12) 位置最高,这表明该位置是所有地区中生态最多样化的地区。在上述地点也监测了物种丰富度 (S)。多样性得分 0.83 在 Mahi 河的 Galteshwar (M-12) 位置最高,这表明该位置是所有地区中生态最多样化的地区。
