Researchers from the University of Exeter have predicted what changes await the fishing industry in the next 40 years in the process of warming seas. We are talking about an increase or decrease in the population of certain fish. The study is published in the Journal of Applied Ecology.
The Celtic Sea, English Channel, and the southern North Sea have warmed significantly over the past 40 years, and sea temperatures are expected to rise further in the coming decades. According to scientists, predicting future changes can help prepare the fishing industry and management systems for environmental, social, and economic consequences.
According to the forecast, the number of heat-adapted representatives will increase red mullet, common flounder, and yellowtail flounder. On the other hand, the number of species that are accustomed to cold seas will decrease atlantic cod, monkfish, and megrim.
These changes will affect fisheries management systems as well as future fishing mortality rates, fishing effort, and allowable catches. For example, endangered species may need further action to reduce their vulnerability to warming.
Increasingly flexible and adaptive approaches are required that mitigate climate impacts on fish species and also facilitate industry adaptation.
Our results indicate that climate change will continue to affect fish stocks in this marine region in the future. We have shown both the potential risks and the opportunities that fishermen are likely to have. in the near future to adapt.
