Blue marlin blues: Loss of dissolved oxygen in oceans squeezes billfish habitat
Description: Blue marlin, other billfish and tropical tuna are high energy fish that need large amounts of dissolved oxygen. Scientists are sounding an alarm that the expansion of dead zones is shrinking the useable habitat for these highly valuable fish in the tropical northeast Atlantic Ocean. As dead zones shrink habitat by depriving fish of areas with enough dissolved oxygen for them to thrive, they squeeze these species into surface waters where they are more vulnerable to fishing.
