Dagur Gule Fish (Mudskipper) – The Walking Fish of Sundarban

By /

Introduction

The rivers, creeks, and mudflats of the Sundarbans hold some of the most unique creatures in the world. Among them, the Dagur Gule Fish, scientifically known as the Mudskipper, is one of the most fascinating. Unlike most fish that live entirely underwater, mudskippers can also “walk” on land – making them truly special. Locals of Sundarban affectionately call it Dagur Gule, and many consider it a delicious local delicacy.

Scientific Information

  • Common Name: Mudskipper
  • Local Name: Dagur Gule Fish, Gule Fish
  • Scientific Name: Periophthalmus spp.
  • Family: Gobiidae
  • Habitat: Rivers, creeks, mangrove forests, and tidal flats of Sundarban

Appearance

The body of a mudskipper is elongated, usually greyish or brownish with bright blue spots scattered along its skin. Its eyes are positioned on top of its head, allowing it to watch for predators and prey. The pectoral fins are strong and adapted to help it hop, crawl, and even “walk” on muddy land.

Lifestyle & Special Features

  • Survival on Land: Mudskippers breathe through their skin and the mucous lining of their mouth, enabling them to stay out of water for long periods.
  • Tidal Life: During low tide, when water recedes from the river, they move across the mudflats in search of food and interact with each other.
  • Burrow Dwellers: They dig burrows in the mud, which act as their home and a safe place for breeding.

Mudskipper in Sundarban

In the Sundarbans, mudskippers are most commonly seen during the monsoon and winter seasons. About 15–20 years ago, local fishermen could catch them in large numbers, but now their population has decreased due to:

  • Overfishing
  • Habitat destruction (cutting of mangrove forests)
  • Pollution

Cultural & Economic Importance

  • As Food: In Sundarban villages, Dagur Gule Fish is a favorite seasonal delicacy. Locals say it has an amazing taste – tender meat, rich flavor, and a unique aroma that makes it stand out from other fish.
  • Cooking Style: It is often prepared as spicy curry, fried until crispy, or slow-cooked with seasonal vegetables.
  • Medicinal Use: In certain Chinese traditional medicines, mudskippers are used.
  • Tourism Attraction: Tourists enjoy watching these walking fish during low tide in the Sundarbans.

Nutritional Value

Dagur Gule Fish is rich in protein, omega-3 fatty acids, vitamins, and minerals. Its soft flesh and healthy fat content make it not only delicious but also nutritious.

Need for Conservation

Mudskippers are an important indicator species for the Sundarban ecosystem. To protect them, we must:

  • Preserve mangrove forests
  • Stop overfishing
  • Raise awareness among local communities

Conclusion

The Dagur Gule Fish is a true wonder of nature – a fish that walks on land, thrives in the mangrove mudflats, and offers an amazing taste that locals cherish. Protecting these fascinating creatures will ensure that future generations can enjoy both their beauty and their flavor.
