Hilsa kelee

Clupea kanagurata Achilles 162

Hilsa kelee is a species of fish belonging to the family Clupeidae, which is known for including species such as herrings, sardines, and anchovies. The Hilsa kelee, often simply referred to as kelee shad, is found in marine, brackish, and fresh waters of the Indo-Pacific region. This species is of significant ecological and economic importance in several countries where it is found, due to its popularity as a food fish.

Description

The Hilsa kelee can be distinguished by its elongated body, which is typical of the members of the Clupeidae family. It has a silvery appearance with a distinct blue-green sheen on its dorsal surface, which helps in camouflage within its aquatic environment. The fish usually reaches a length of about 20 cm, but can grow up to 40 cm in some cases. It has a deeply forked tail and a single dorsal fin, along with a series of small, sharp scales along its belly, known as scutes.

Habitat and Distribution

The Hilsa kelee is widely distributed across the Indo-Pacific region, from the east coast of Africa, through the Indian Ocean, to the western Pacific Ocean. It inhabits a range of environments, including open seas, coastal areas, estuaries, and rivers. This adaptability to different salinities allows the Hilsa kelee to migrate between marine and freshwater habitats, a behavior known as diadromy.

Diet

The diet of the Hilsa kelee primarily consists of plankton, small fish, and crustaceans. Its feeding habits are opportunistic, and the fish is known to form large schools when feeding, which is a common behavior among clupeids.

Economic Importance

In regions where the Hilsa kelee is abundant, it is a significant source of food and income. The fish is caught using traditional and commercial fishing methods and is sold fresh, dried, or smoked. Its popularity stems from its flavorful flesh, which is highly prized in culinary traditions of the Indo-Pacific region.

Conservation

While the Hilsa kelee is not currently listed as endangered or threatened, its populations are subject to the same pressures as many other fish species, including overfishing, habitat destruction, and pollution. Efforts to manage fish stocks sustainably and protect critical habitats are essential for ensuring the long-term viability of this species.

Cultural Significance

In some cultures, the Hilsa kelee holds particular cultural significance, similar to its relative, the Hilsa or ilish (Tenualosa ilisha), in South Asia. Festivals and culinary traditions often celebrate the seasonal arrival of the fish, highlighting its importance beyond mere sustenance.
