Ynghylch

The European seabass is a predatory fish found around the UK. They are highly mobile, migrating inshore in summer months when they are found in estuaries and surprisingly far upstream in rivers. In the winter months they move offshore and then in spring will gather in large shoals to spawn. They feed on crustaceans and small fish such as sand eels. Estuaries are also an important nursery habitat for juvenile seabass, where the sheltered conditions and plentiful food supply make for a great place to grow. They are particularly slow growing and don't reach sexual maturity until the age of 4-8 years old.

Identifiable by its silvery colour, this large fish has two distinct dorsal fins, the first of which has 8 or 9 spines. Juveniles are recognisable by the black spots on their upper body; these spots are normally absent in adults.

Habitats

Roeddech chi yn gwybod?

Seabass was one of the first fish to be grown in fish farms in Europe. As they love estuaries and coastal waters, they thrived in early attempts to rear them in coastal lagoons in the Mediterranean. They are now reared commercially - in fact, the seabass you eat in the UK has probably come from a Mediterranean fish farm!

Sut y gall bobl helpu

Choose sustainably sourced seabass - the best option is farmed seabass grown in a recirculating system. If this is not available, any farmed seabass is a better choice than wild caught fish. The Wildlife Trusts are working with fishermen, researchers, politicians and local people towards a vision of 'Living Seas', where marine wildlife thrives.
