Aquatic Systems & Ecology

Fish of Nainital & Sustainable Aquaculture

Conserving indigenous cool-water fish in Nainital's fragile lakes and developing closed-system, eco-friendly recirculating aquaculture to empower youth and protect watersheds.

Environmental Venture

Ecological Closed-System Aquaculture

Modern Recirculating Aquaculture Systems (RAS)

Traditional open-pond aquaculture can discharge pollutants, feed residues, and fish waste directly into local public lakes, causing severe eutrophication. To counter this, Cottonspace champions high-tech closed-system ventures.

By utilizing closed recirculating tanks, flow-through raceways, and protective inland ponds, we maintain pristine water standards, isolate waste for organic farming fertilization, and offer highly sustainable employment and entrepreneurship support to regional youth.

Key Local Fish Species

Important aquatic residents of Kumaon lakes

Golden Mahseer

Tor putitora

Known as the "Tiger of the Indian Rivers", this majestic, large migratory fish is native to the cold rapids and deep lakes of the Himalayas. Highly endangered due to damming and habitat loss, they are protected through our lakeshore buffer zone policies.

Snow Trout (Asela)

Schizothorax richardsonii

An indigenous species that thrives in pure, fast-flowing mountain waters. Their feeding habits keep regional rocky streams free of excessive algal buildup, making them a crucial indicator species of environmental health.
