Mizuhopecten yessoensis

Mizuhopecten yessoensis, commonly known as the Yesso scallop, is a species of bivalve belonging to the Pectinidae family. It is native to the northwest Pacific Ocean, particularly around Japan, Russia, and Korea.

Description

The Yesso scallop is a large scallop species, with adults typically reaching a shell height of 15-20 cm. The shell is fan-shaped and features a series of radial ribs. The color of the shell varies from white to light brown, with the interior being glossy white.

Habitat and Distribution

The Yesso scallop is found in the cold waters of the northwest Pacific Ocean. It is particularly abundant around the coasts of Japan, Russia, and Korea. The species prefers sandy or muddy substrates and is typically found at depths of 20-40 meters.

Life Cycle

The life cycle of the Yesso scallop begins with the release of eggs and sperm into the water column. After fertilization, the resulting larvae drift in the plankton for several weeks before settling onto the seabed and metamorphosing into juvenile scallops. The juveniles grow rapidly and reach sexual maturity within 2-3 years.

Economic Importance

The Yesso scallop is of significant economic importance in the regions where it is found. It is commercially harvested for its meat and is also cultivated in aquaculture operations. The species is particularly valued for its large size and sweet flavor.

Conservation

While the Yesso scallop is not currently considered threatened, it is vulnerable to overfishing and habitat degradation. Efforts are being made to manage harvest levels and protect the species' habitat to ensure its long-term survival.
