In India, this fish species is extensively farmed in states like West Bengal, where it usually goes by the name of rohu or catla.

However, the original rohu fish is Labeo rohita, which does look similar to this white carp. In ponds and streams, the carp mrigal dwells at the bottom and it likes to remain in shallow water.

Mrigal Fish Interesting Facts

What type of animal is a mrigal fish?

The mrigal is actually two species of ray-finned fish that are quite close to each other, Cirrhinus cirrhosus and Cirrhinus mrigala. As a member of the carp family, it is considered to be a part of the Indian major carps and is widely used as a food source in different South Asian countries.

What class of animal does a mrigal fish belong to?

As a species of ray-finned fish, the mrigal belongs to the class Actinopterygii. Even the jack fish is part of this class. Both fishes are also part of the subfamily Labeoninae that contains the Labeo rohita or rohu fish. The genus Cirrhinus is also shared by both fishes.

How many mrigal fish are there in the world?

Because the mrigal fish is used in aquaculture and for production of food, it is hard to note the population of this species.

Where does a mrigal fish live?

This fish is found in different areas of South Asian countries. However, the mrigal carp is said to be native to streams of India, at its only wild population is found in the Cauvery River.

Whereas, the Cirrhinus mrigala is found in different South Asian countries like Bangladesh, Pakistan, Sri Lanka, Myanmar, Thailand, and Laos. Due to its huge demand, these fish are also being imported to other countries as human food. We cannot call the mrigal to be endemic to a particular place.

Now, if you visit India, it is easy to spot mrigal fish in different lakes and ponds as this species is grown extensively. However, if you want to watch the fish being farmed, make sure to visit West Bengal.

What is a mrigal fish's habitat?

Both fishes prefer a shallow freshwater environment like streams, rivers and lakes. These fishes like to reside in areas with gravel on the bottom. In the wild, it is unable to breed in confined spaces like ponds, but artificial breeding has led to these being kept in ponds. Often the spaces of aquaculture are quite small and often overpopulated.

Who do mrigal fish live with?

These fishes will often live in schools or groups in a lake or a river. In its natural habitat, you can often find them swimming around in groups during the breeding season.

When it comes to farmed fish, you may find a huge number being raised in ponds or fishing beds. This is mainly due to the huge demand for carp species as food.

How long does a mrigal fish live?

In a natural environment, a mrigal fish can live up to 12 years. However, as it is one of the most farmed fish in India as well as in other South Asian countries like Pakistan and Bangladesh, it is caught when it reaches a good size and the range is usually two years.

How do they reproduce?

This carp species reaches sexual maturity at the age of two years. The egg production capacity of a female often depends on its age, but usually, it can produce a range of around 1-1.5 million eggs every breeding season.

The mrigal carp prefers to remain in shallow water as the female lays eggs at a depth of around 39 in (99 cm). In natural circumstances, the breeding season begins with the entry of the southwest monsoon in South Asia, which is usually between the months of May and September.

However, as a farmed fish, the species often goes through artificial breeding and induced breeding. In a farm, the fry has a survival rate of 30-50%, and if it's successful, the length and weight of this fish can drastically increase in only a few months. The fingerlings are kept in a grow-out system for 10-12 months

What is their conservation status?

 Because of the low natural population of Cirrhinus cirrhosus or mrigal carp, it has been classified by the International Union for Conservation of Nature (IUCN) as Vulnerable. However, the mrigal fish (Cirrhinus mrigala) is still thriving in different parts of South Asia, so its classified under the status of Least Concern.
