Humboldt Squid Size (IMAGE) Hiroshima University Caption A study of the Humboldt squid's genetic stocks led by Hiroshima University marine biologists and in collaboration with researchers from Peru found that there is no north-south divide for this cephalopod's population. As warming waters affect their migration routes and push these large cephalopods to stretch toward the poles, they risk exposing themselves to more fishery fleets that are trying to satisfy the growing global appetite for squids. The researchers are calling for more international cooperation among governments along this squid's migration route to ensure sustainable fishing.
