Perna canaliculus

Perna canaliculus, commonly known as the New Zealand green-lipped mussel, is a bivalve mollusk in the family Mytilidae. It is endemic to New Zealand, where it is also known as the New Zealand mussel, the green-lipped mussel, and by its Māori name, kuku.

Description

The Perna canaliculus is a large mussel, measuring up to 240 millimeters in length. It has a dark greenish-brown shell, with a bright green lip around the edge, which gives it its common name. The inside of the shell is smooth and shiny, and is a pearly white color.

Distribution and habitat

The Perna canaliculus is found only in New Zealand, where it is widespread around the country's coastline. It prefers rocky shorelines and is often found in large colonies. The species is particularly common in the Marlborough Sounds and the Hauraki Gulf.

Uses

The Perna canaliculus is commercially harvested in New Zealand. It is a popular food source, both domestically and for export. The meat of the mussel is rich in protein, omega-3 fatty acids, and other nutrients.

In addition to its use as a food source, the Perna canaliculus is also used in the production of dietary supplements. These supplements are marketed for their potential benefits to joint health, due to the presence of a unique combination of fatty acids found in the mussels.

Conservation

While the Perna canaliculus is not currently considered to be at risk, there are concerns about the potential impacts of over-harvesting and habitat loss. Efforts are being made to manage the commercial harvest of the species to ensure its long-term survival.
