The Shrinking Catch: Climate Change and War Take Their Toll on Tinned Fish Supplies
The recent surge in tinned fish sales may have you wondering if this is just another fleeting food trend. However, behind the scenes, a perfect storm of climate change and war in Iran is shrinking the supply of sardines, Morocco’s top export.
According to Rashid Sumaila, a professor at the University of British Columbia who has spent his career studying fisheries and their vulnerability to geopolitical forces, the combination of warmer water and higher fuel costs constitutes a “double whammy” for Moroccan fishermen. As sardines shift toward cooler waters, fishermen are forced to travel farther to catch them, but the yield is less guaranteed due to rising temperatures.
The war in Iran has driven up fuel costs, making it even more expensive for fishermen to reach their usual fishing grounds. This situation is further complicated by warmer waters, which are pushing sardines into new territories. As a result, fishermen are bringing back nearly half the quantity they used to.
Climate change and government subsidies that encourage overfishing are compounding this problem. The latter has contributed to global fisheries subsidies reaching $35.4 billion in 2018, with a significant portion classified as capacity-enhancing subsidies that fuel overfishing. This not only shrinks fish populations but also forces boats to travel even farther for a shrinking catch.
The impact of these issues will be felt globally, rather than just within Morocco’s borders. Canned sardine exports have already fallen from 70% of the country’s small open-sea fish exports in 2020 to 23% in 2025. Climate change is a major factor, with warmer waters affecting fish migration patterns and making it harder for fishermen to catch what they need.
The consequences of these subsidies are far-reaching and will have a lasting impact on household budgets worldwide. As Sumaila notes, affordability pressure isn’t limited to lower-income countries; it’s a global issue that affects everyone. Even in developed nations like Canada, the price dynamics show up in people’s grocery bills, putting pressure on consumers.
The situation highlights the need for sustainable fishing practices and responsible management of fisheries. Governments must rethink their subsidies policies and focus on supporting research and conservation efforts rather than fueling overfishing. Consumers also have a role to play by choosing sustainably sourced seafood options.
In addressing these issues, it’s essential to prioritize sustainability and responsible resource management to ensure that the catch of tomorrow is as plentiful as today. The interconnectedness of climate change, war, and global supply chains serves as a stark reminder that our choices have consequences for the planet’s future.

It's ironic that tinned fish sales are up despite dwindling supply. The real concern isn't just for sardine lovers, but for the future of our oceans and fisheries management. While the article highlights climate change and war as primary factors, I think we're missing a crucial piece: the role of consumerism in perpetuating unsustainable fishing practices. By buying into trendy tinned fish, are we inadvertently supporting overfishing? We need to consider the broader implications of our food choices and push for more responsible sourcing practices from fishermen to consumers.

The real cost of our convenience foods is finally coming into focus. While tinned fish prices may remain stable for now, the article glosses over the economic impact on small-scale fishermen who rely on this industry. As bigger boats are incentivized to travel further and exploit these depleted waters, local communities risk losing a vital source of income. It's not just about supply chain resilience – it's about the human cost of our appetites for cheap, imported fish.

"The statistics on tinned fish supply are clear: climate change and war have taken their toll on Morocco's sardine exports. But what about the ripple effect? As global demand for sustainable seafood grows, what will happen to small-scale fishermen who can't compete with industrial fleets subsidized by governments? We need to look beyond just the numbers – we need to consider the human cost of this perfect storm and the long-term consequences for coastal communities."
