Sillago

Species of fish

Sillago is a genus of fish in the family Sillaginidae, commonly known as smelt-whitings. These fish are found in the Indo-Pacific region and are known for their elongated bodies and silvery appearance.

Description

Sillago parvisquamis

Members of the genus Sillago are characterized by their slender, elongated bodies and a distinctive silvery coloration. They typically have two dorsal fins, with the first dorsal fin being spiny and the second soft-rayed. The anal fin is also soft-rayed. The body is covered with small, cycloid scales.

Distribution and habitat

Sillago species are distributed throughout the Indo-Pacific region, from the eastern coast of Africa to the western Pacific Ocean. They inhabit coastal waters, estuaries, and sometimes enter freshwater rivers. These fish are often found over sandy or muddy substrates where they can blend in with their surroundings.

Diet

The diet of Sillago species primarily consists of small invertebrates, such as crustaceans and polychaete worms. They are benthic feeders, using their elongated snouts to probe the substrate for food.

Reproduction

Sillago species are known to spawn in shallow coastal waters. The eggs are pelagic, and the larvae are planktonic, drifting with the currents until they develop into juvenile fish and settle in suitable habitats.

Economic importance

Sillago species are of commercial importance in many regions, particularly in Southeast Asia and Australia. They are caught using various methods, including trawling and seine nets, and are valued for their delicate flesh.

Species

The genus Sillago includes several species, some of which are:

• Sillago sihama - commonly known as the silver sillago or northern whiting.
• Sillago japonica - known as the Japanese whiting.
• Sillago parvisquamis - the small-scale whiting.
