The research, published in the journal Fish and Fisheries, shows that traditional fisheries targeting large predators such as cod and haddock, have declined over the past hundred years. In their place, catches of shellfish such as prawns, scallops and lobsters have rocketed as they begin to thrive in unnaturally predator-low environments often degraded by the passage of trawls and dredges.
In many places, including the UK, shellfish are now the most valuable marine resource. The research by the Environment Department at York suggests that although a shellfish-dominated ecosystem appears beneficial from an economic perspective, it is highly risky.
Like simplified agricultural systems, these shellfisheries are unstable in the long-term and at great risk of collapse from disease, species invasions and climate change.
Lead author, Leigh Howarth, says: "Prawns are now the most valuable fishery in the UK, with catches currently worth over £110 million a year. But this fishery has come to exist only after we overexploited populations of cod, haddock and other predators. If shellfish now collapsed the social consequences for fishermen would be devastating. There are simply very few remaining species left to target."
The study reports similar findings from all over the world. In the United States and Canada, catches of lobster, scallops and crab have also come to dominate following the collapse of cod. However, disease and climate change again put these species at great risk.

But unlike his father and grandfather, his boat no longer runs on an old diesel engine that burns fuel and clouds the sky with smoke. Instead, it’s powered by a hybrid engine that saves 40% fuel—funded by an ESG program from a major seafood exporter.
(seafood.vasep.com.vn) Vietnam's pangasius industry is shifting its focus from increasing production volume to enhancing value-added products in order to meet the increasingly stringent requirements of export markets. In An Giang Province—the country's leading hub for pangasius farming and processing—businesses and farmers are prioritizing product quality, traceability, food safety, and sustainable development rather than expanding output.
(seafood.vasep.com.vn) Following strong growth in 2025, Vietnam’s tuna exports to Sweden continued to edge higher during the first five months of 2026. However, the picture is far from straightforward. Orders have fluctuated significantly from month to month, indicating that this market remains cautious, with purchasing decisions closely tied to actual demand and the import cycles of Nordic distributors rather than to a steady upward trend.
(seafood.vasep.com.vn) China’s shrimp imports in the first five months of 2026 continued to surpass the same period in 2025, indicating that demand in the world’s largest seafood-consuming market remains strong. However, behind the growth figures lies an increasingly competitive landscape: Ecuador dominates the competitively priced whiteleg shrimp segment, India remains the second-largest supplier, while Vietnam stands out in the lobster segment but still needs to strengthen its advantages through quality, traceability, and reliable supply.
