Mrigal carp

Cirrhinus mrigala

Also calledMrigel মৃগেল (Bengali) · Nain नैन (Hindi) · Mori موری (Punjabi/Urdu)

The bottom-feeding member of the Indian major carp trio. It grazes the detritus and algae on the pond floor beneath rohu and catla.

Cirrhinus mrigala is a species of ray-finned fish in the genus Cirrhinus. It is found in northern India, Pakistan, Bangladesh and Nepal. This species and the Mrigal carp are both considered distinct. Wikipedia

§1

What it can do

  1. iFeeds on decaying organic matter and algae on the bottom, recycling nutrients that other farmed carps cannot use
  2. iiTolerates a wide range of temperatures and low water quality
  3. iiiBreeds readily in hatcheries after hormone injection

In the field

Field marks

  • aSlender, streamlined silvery body with a dark grey back
  • bPectoral, pelvic and anal fins tipped orange-red, brighter in the breeding season
  • cBlunt snout with thin, unfringed lips and one pair of short barbels
  • dEyes golden
Not to be confused with
Rohu has a deeper body, reddish scale centres and thick fringed lips. The white carp (Cirrhinus cirrhosus) of peninsular India is very similar and is told apart by details of scales and fins.
Where to see it
Fish markets and ponds across West Bengal, Bangladesh and Punjab; reservoirs of the Gangetic plain
When
Resident; spawns June–August with the monsoon floods
§3

Life & habits

Diet
Detritus, decaying plant matter, benthic algae and small invertebrates
Habitat
Lower layers of rivers, reservoirs and ponds
Size
Commonly 40–60 cm; up to about 1 m and 12 kg
Lifespan
Up to about 12 years

Moves in schools along the bottom sifting mud; wild fish spawn in flooded river margins during the monsoon.

Marginalia

Buchanan-Hamilton's 1822 account of Ganges fishes recorded mrigal under its local name. Rohu–catla–mrigal 'composite fish culture' was developed by Indian fisheries scientists from the 1960s and spread across South Asia.

Curiosity

Because each species feeds in a different layer, a pond stocked with catla, rohu and mrigal together gives a bigger harvest than the same pond stocked with only one of them.
