Katla fish is a fast-growing, economically important South Asian freshwater carp with a large, broad head and a wide, upturned mouth. It primarily feeds on surface and mid-water organisms like algae, phytoplankton, and insects. Found in rivers and lakes across countries like India, Bangladesh, and Pakistan, it is prized for its food quality and is also widely farmed, with its conservation status listed as "Least Concern".

Biological features

• Appearance: Has large, greyish scales on its back and a whitish belly. Its most distinctive features are its large, broad head, prominent protruding lower jaw, and upturned mouth.
• Habitat: Lives in freshwater and brackish water bodies such as rivers, lakes, and ponds.
• Diet: A surface and mid-water feeder, it is mainly omnivorous. Juveniles feed on phytoplankton and zooplankton, while adults consume a wider variety, including algae, insects, and plant leaves.
• Size: Can grow to a large size, with a maximum recorded length of up to 182 cm and a weight of 38.6 kg.

Distribution and habitat

• Native Range: Native to the river systems of South Asia, including India, Bangladesh, Myanmar, Nepal, and Pakistan.
• Introduced Range: It has been introduced to many other countries in South and Southeast Asia for aquaculture purposes, such as Sri Lanka, Laos, Malaysia, Thailand, and Vietnam.
• Water bodies: Found in rivers like the Ganges and Indus, as well as in lakes, reservoirs, and canals.

Ecology and commercial importance

• Ecological role: As an herbivore that feeds on algae and plankton, it plays a key role in regulating the populations of these organisms and maintaining water quality in its ecosystem.
• Commercial value: Katla is one of the most productive and fast-growing food fish in India and is highly sought after.
• Aquaculture: It is widely farmed, both in monoculture and in polyculture systems with other carp species, due to its fast growth rate and hardiness.

Conservation

• Status:Currently listed as "Least Concern" by the IUCN.
• Threats:Population declines in some areas have been linked to overfishing, habitat degradation, and pollution.
