Benthic macro-biota in Gaula River - Kumaon Himalaya
The density of benthic macro-biota in number over weight of biomass at three sampling stations was 29 units m²/0.614 g m² to 171 units m²/11.346 m² at Station I; 22 units m²/0.410 g m² to 155 units m²/8.717 m² at Station II; 15 units m² 10.321 g m² to 122 units m²/6.793 g m² at Station III. The Caddis fly larvae were the most dominant component and contributed 52.41% in the macro-biota. These animals were abundant in Gaula River when benthic algae were abundant; water is well oxygenated, alkaline and contains sufficient nutrients but observed to be less abundant during high velocity of water, high river depth and higher turbid waters.
