Egyptian fisheries need to be better managed to secure the overall health of the Mediterranean Sea’s marine living resources, new research has found.

In a recent paper in the journal Ocean and Coastal Management, researchers with the Sea Around Us initiative at the University of British Columbia’s Institute for the Oceans and Fisheries and the Arab Academy for Science, Technology and Maritime Transport reconstructed Egypt’s marine fisheries catches from the Mediterranean in the last 100 years and found strong evidence of resource overexploitation. Such overexploitation has pushed fishers to go farther and deeper, increasingly resorting to species lower in the food chain.

Fish that live on or near the seafloor -known as demersal or groundfish- barely feel the impact of marine heatwaves, according to new research that highlights the need to keep seas from warming further.

Climate change-induced droughts and fish kills affect larger fish more severely than smaller individuals, according to new research.

In a paper published in Environmental Biology of Fishes, researchers from Leiden University, Sportvisserij Zuidwest Nederland and the Sea Around Us initiative at the University of British Columbia compared evidence from drought-induced fish kills in the Netherlands, fisheries management literature and multiple physiological studies. They confirmed that when water gets warmer and deoxygenated, larger and older individuals within a species tend to die in greater numbers than their smaller and younger counterparts.
