EDF believes such alignment and that secure fishing rights play an integral role in the redesign and rebuilding of our ocean resources. As with other ecosystem types, healthy coral reef ecosystems exist in a state of balance, and consist of a complex web of life.

Bycatch is a fishing industry term for when fish species are caught by accident while fishing for other target fish. 2. That is why it is difficult to create large scale policies and changes as well.
