The ‘Good Fish Guide’ published by the Marine Conservation Society changed the sea bass to a yellow rating (use with caution), upgrading it from a red rating (don’t use).

Laky Zervudachi, director of sustainability at Direct Seafoods, said: “It’s great that line-caught seas bass has recovered, showing what we can achieve as an industry when all of us- the fishing fleet, suppliers, chefs and retailers- work together.

“However, it would be a concern if sea bass simply went back on menus as a core, year-round dish, or if chefs were less careful about how the sea bass they buy is sourced- not all sea bass on the market is sustainably line-caught. “

The new Good fish Guide from the MCS has changed North Sea cod to a red rating while some monkfish fisheries have moved into the green zone.

Direct Seafoods produces a monthly catch-up newsletter informing customers on sustainability updates. The national supplier offers more than 130 Marine Stewardship Council certified products.
