In many fisheries, many species are caught at the same time. These are called multispecies fisheries, and the fact that they catch many species together, with the same gears, means that the different species are caught at the same rate. The trouble is, some species are productive enough to withstand high catches while others are not. So as a result, the low-productivity species get fished out, reducing overall yield, markets for diverse species and economic and ecological resilience — resulting in serial depletion. While many single-species fisheries are becoming more sustainable thanks to science-based management strategies, multispecies fisheries often face greater sustainability challenges, and these challenges will grow in the face of climate change.
