Our oceans are in crisis, and a beloved fish is paying the price. Waitrose, a leading UK supermarket, has taken a bold step by suspending the sale of mackerel due to overfishing, marking a significant shift in the industry. But here's where it gets controversial: while Waitrose is redirecting customers to sustainable alternatives like herring and sardines, the move raises questions about the broader responsibility for protecting our seas. Is it enough for retailers to act, or should governments and consumers share the burden?
Last year, the Marine Conservation Society (MCS) sounded the alarm, warning that mackerel stocks were nearing a breaking point due to excessive fishing. The organization downgraded mackerel from a three to a four on its five-point sustainability scale, signaling a critical need for change. Kerry Lyne, an MCS representative, commended Waitrose’s decision, emphasizing that preserving favorites like mackerel requires collective effort across the supply chain, with fishing strictly limited to sustainable levels.
And this is the part most people miss: a January study from the University of East Anglia urged supermarkets to encourage consumers to diversify their seafood choices, opting for more environmentally friendly and locally sourced options. This isn’t just about mackerel—it’s about reshaping our entire approach to seafood consumption. For instance, herring and sardines, often overlooked, are not only sustainable but also packed with nutrients, making them a win-win for both the planet and our health.
The situation became even more dire last September when the International Council for the Exploration of the Sea (ICES) recommended a 70% cut in mackerel fishing in the north-east Atlantic to restore populations to sustainable levels. Hugo Tagholm, executive director of Oceana UK, issued a stark warning: “We’re risking the total collapse of this species and endangering countless others in the process.” Despite this, UK nations agreed to only a 48% reduction in December, falling short of ICES’s recommendations.
WWF echoed these concerns, highlighting that north-east Atlantic mackerel catches have exceeded recommended levels by an average of 39% since 2010, pushing the population to the brink. The latest data reveals that, starting in May, mackerel catches in the region will no longer meet the Sustainable Seafood Coalition’s standards. Tagholm called for systemic change, pointing out that the blame doesn’t lie solely with retailers or consumers. “The government sets catch limits and has failed repeatedly to implement a coherent strategy to end overfishing,” he said. “With staple fish like cod and mackerel on the verge of collapse, immediate action is non-negotiable.”
Waitrose is now promoting herring, sardines, and sea bass as sustainable and nutritious alternatives. Marija Rompani, director of ethics and sustainability at the John Lewis Partnership, which owns Waitrose, stressed the importance of balancing climate action, nature protection, and responsible sourcing to safeguard our oceans.
But here’s the controversial question: Is it fair to place the burden of sustainability on supermarkets and consumers, or should governments take the lead in enforcing stricter fishing regulations? And how can we ensure that sustainable seafood becomes the norm, not the exception? Share your thoughts in the comments—this is a conversation we all need to have.
