Mrigal/White Carp: A True Champion of the Carp Family

Bengalis and their love for large fish is a timeless affair. We cannot go long without our beloved macher jhol, and the obvious champion of patla macher jhol (light fish gravy) comes from the carp family. Every other day, Bengali households prepare big carp fish—whether Rui, Katla, or Mrigal. Mrigal holds a special place in Bengali hearts as one of our most cherished fish. Like Rui, Mrigal’s flesh is sweet and tender. It is as delightful to eat as it is easy to cultivate. Available in markets year-round, Mrigal fish has a distinctly faded skin color compared to other carp varieties, earning it the nickname “White Carp.”

Introduction to Mrigal Carp

The Mrigal fish is a freshwater carp species found in the South-Asian rivers, particularly in Bangladesh and India. What makes mrigal special is its ability to reproduce and grow fast. As one of the fastest-growing carp species, it is exceptionally well-suited for commercial pond farming. It plays a very crucial role in Bangladesh’s aquaculture industry as part of the traditional fish farming system alongside roho labeo (rui) and catla (katla). White carp’s wild population is now vulnerable and mainly found in India’s Cauvery River. Mrigal, however, thrives in fish farms across South Asia. Bangladesh has become one of the world’s largest producers of mirgal fish. We now contribute significantly to the global production of this prized fish. The only challenge for farmers is that Mrigal needs special breeding techniques since it won’t reproduce naturally in ponds.

Physical Characteristics of Mrigal or White Carp

Mrigal has a sleek, long body that can grow up to 1 meter in length. They usually weigh between 8-12 kg. These beautiful fish have gray backs with shimmering silver sides. During breeding season, their fins develop attractive orange tips. They have a single pair of short whiskers near their mouth. Mrigal are bottom dwellers that feed on small insects, organic matter, and decomposed materials from the riverbed or pond bottom. This feeding habit makes them perfect for aquaculture. They feed on the bottom dwellers of the pond to keep it clean. These fish reach maturity in just 2 years. A mature female mrigal can carry up to half a million eggs. In nature, they breed between April and June in the rivers. However, they won’t breed in still pond water, so commercial fish farms must use special hatchery techniques to produce hatchlings artificially.
