The fishermen and women's proximity to the coastal waters has made them front-line witnesses of how climate change is altering the ecosystem of the North Sea.
Oceans have absorbed 90% of the global warming that humans have caused in the last few decades, according to NASA.
In the North Sea, surface temperatures have increased by around 0.3 degrees Celsius per decade since 1991.
While shrimp populations fluctuate during short-term changes like heatwaves, fishermen and scientists report increases in lesser weever fish and squid, traditionally found further south but which have moved north into Belgium's warming waters.
North Sea cod populations have plummeted since the 1980s, which scientists attribute to rising sea temperatures and overfishing.
