Fishing and climate change: two of the largest human impacts on the ocean. But how do they interact? In a new paper just out in Ecosphere, Emma Fuller, Eleanor Brush, and I use an ecological model to build some intuition. We looked specifically at how fishing affects the ability of species to shift their distributions fast enough to keep up with climate velocity. Two main take-home messages:
- Fishing the leading edge of a species range has the biggest impact (this also tends to be where fishing is unregulated….)
- Marine protected areas (MPAs) can actually make it harder for species to keep up with climate if the MPAs concentrate fishing effort in narrower areas.
