Key identification features
- Large, deep-bodied fish with a broad, flattened head
- Prominent, upturned lower jaw and a wide, terminal to slightly upward-facing mouth
- No barbels at all around the mouth (a key diagnostic point)
- Large, silvery-grey scales with a darker olive-grey back
- Large, well-developed dorsal fin
- Fins generally dusky grey with no bright coloration
Common look-alikes
- Rohu: has a pair of short barbels and a more pointed, less upturned snout, with a slimmer overall body
- Mrigal: possesses barbels and a more streamlined, tapered head, plus a reddish tinge to the fins that catla lacks
- Silver Carp: similarly large and silvery but has a distinctly keeled belly running further forward and much smaller eyes set very low
Where you'll see one
Catla are a surface- and mid-water-feeding species native to the major river systems and floodplain lakes of South Asia. They are also one of the most widely farmed carp species in the region, so they are commonly encountered in stocked ponds and reservoirs as well as natural rivers.
Frequently asked questions
How do I tell a catla from a rohu?
Check for barbels: rohu has a pair of barbels near the mouth, while catla has none at all; catla's head is also broader and its lower jaw more distinctly upturned.
What is the single most reliable feature for identifying a catla?
The complete absence of barbels combined with a broad, upturned mouth is the most reliable field mark, since most similarly sized South Asian carps show at least one pair of barbels.
