Iconic marine predators such as sharks, tunas, swordfish, and marlins are becoming increasingly rare under current fishing trends, according to a new study published in the journal Marine Ecological progress Series. In half of the North Atlantic and North Pacific waters under national jurisdiction, fishing has led to a 90-per-cent decrease in top predators since the 1950s, and the impacts are now headed south of the Equator. The study was lead authored by former Sea Around Us Project M.Sc student Laura Tremblay-Boyer. The study is available here and the press release is here.
