英国海洋保护协会对多种鱼类的可持续性评级进行了调整，其中无须鳕遭到最严厉的降级——从琥珀色跌至红色（最低评级）1。欧洲长尾鳕的评级也从绿色下调至琥珀色1。在最新一轮对727项评级的审查中，共有29项被下调，11项上调1。
这些变化反映了英国及周边海域鱼类种群面临的压力。鳕鱼种群自2015年以来持续下降，过度捕捞被认为是主要原因1。该慈善机构建议消费者多样化选择海鲜品种，改用海鲈鱼替代鳕鱼1。相比之下，英国大西洋蓝鳍金枪鱼的情况有所好转，最近获得了绿色评级，这得益于20多年前实施的渔业管理措施促进了种群恢复1。
A British marine conservation organization has revised its sustainability assessments for two popular fish species, reflecting declining populations in waters surrounding the UK. 1 Saithe, a whitefish also known as coley, has received the most severe downgrade, dropping from amber to red—the lowest possible rating—while European hake fell from green to amber. 1
Among the 727 fish stocks under review, the latest assessment cycle saw 29 ratings downgraded and 11 upgraded overall. 1 The organization noted that hake populations have been in decline since 2015, primarily due to overfishing. 1 In response to these concerns, the charity has advised consumers to diversify their seafood choices and consider substituting sea bass for cod. 1
Not all news was negative in the updated ratings. Atlantic bluefin tuna caught around the UK received a new green rating, a recovery attributed to fisheries management measures implemented more than two decades ago. 1 According to the organization's representative Kerry Lyne, "fish stock conditions continue to change," underscoring the importance of ongoing monitoring and adaptive consumer choices. 1
