In the Gulf of Mexico, bycatch of Kemp's ridley turtles in shrimp trawlers was cited as a major factor in declines of the species. The consequent application of lowered limits to allowable catches, in order to minimise stock overexploitation risks, further reduces stock availability to legitimate participants. For example, studies on diver harvesting of oyster showed that the technique was less damaging to the structure of the reef than traditional methods like dredging. These whales were hunted for their baleen as well as for their meat, which was either eaten or made into oil. In this method, fishermen light sticks of dynamite and toss them into the water. This in turn causes harmful algal blooms that can cause widespread die-offs of marine life.

Addressing this in the face of growing population and climate change will be difficult, but will be vital if Indonesia and others want to dial down tensions over transnational resources.
