To successfully manage fisheries, factors in the environment that affect fish — like food sources, predators and habitat — should be considered as part of a holistic management plan. That approach is gaining traction in fisheries management, but there has been no broad-scale evaluation of whether considering these ecosystem factors makes any economic sense for the commercial fishing industry. A team of ecologists and economists has addressed that question in the first study to test whether real-life ecological interactions produce economic benefits for the fishing industry.
