Pagrus major, commonly known as the Red seabream, is a species of marine fish in the family Sparidae. It is native to the western Pacific Ocean, particularly around Japan, China, and Korea. This species is highly valued both as a food fish and in recreational fishing.

Description

Pagrus major has a deep, laterally compressed body with a distinctive pinkish-red coloration. The fish can grow up to 100 cm in length and weigh as much as 10 kg. The dorsal fin is long and continuous, with a spiny anterior portion and a softer posterior portion. The anal fin is shorter but similarly structured.

Habitat

The Red seabream inhabits coastal waters, often found over rocky substrates and sandy bottoms. It is commonly found at depths ranging from 10 to 200 meters. Juveniles tend to stay in shallower waters, while adults can be found in deeper areas.

Diet

Pagrus major is an omnivorous species, feeding on a variety of benthic organisms. Its diet includes crustaceans, mollusks, and small fish. The species is known for its strong jaws and teeth, which are well-adapted for crushing hard-shelled prey.

Reproduction

The species is known for its protandrous hermaphroditism, meaning individuals first mature as males and later can change to females. Spawning typically occurs in the spring and summer months. Fertilized eggs are pelagic, and larvae are planktonic until they settle to the bottom as juveniles.

Economic Importance

Pagrus major is a significant species in commercial fisheries and aquaculture. It is highly prized in Japanese cuisine, where it is known as "Madai" and is often served in dishes such as sashimi and sushi. The fish is also popular in Chinese cuisine and is often featured in festive meals.

Conservation

While Pagrus major is not currently listed as an endangered species, overfishing and habitat degradation pose potential threats. Sustainable fishing practices and aquaculture are essential to ensure the long-term viability of this species.
