Instead of restricting areas by their location, mobile reserves would identify particular conditions that attract marine life "The stationary reserves do little to protect highly mobile animals, like most of the fish, turtles, sharks and seabirds," [says] Larry Crowder [of] Stanford University. "We think of protected areas as places that are locked down on a map. But places in oceans are not locked down, they move."
...One potential mobile marine reserve could protect the north Pacific convergence zone, a region where two giant currents meet head-on, bringing plankton, small fish, turtles and major predators together. The zone is always teeming with life, but it moves from season to season.-- report
