Someone needs to translate "The Tragedy of the Commons" into Spanish.
From Wikpedia:
The
tragedy of the commons is a dilemma arising from the situation in which multiple individuals, acting independently and rationally consulting their own self-interest, will ultimately deplete a shared limited resource even when it is clear that it is not in anyone's long-term interest for this to happen. This dilemma was first described in an influential article titled "The Tragedy of the Commons," written by
Garrett Hardin and first published in the journal
Science in 1968.

Then we could take up the North American Wildlife Conservation Model, which asserts that the nation's fish and wildlife are held in trust for all citizens, harvest opportunity is allocated to individuals by law and regulation, regulations including seasons and bag and creel limits are guided by science, all citizens have equal opportunity to harvest fish and wildlife, frivolous destruction of fish and wildlife is prohibited, and commercial exploitation of fish and wildlife is banned. This system was developed in the late 1800s - early 1900s by elites (gentlemen sportsmen-naturalists) such as Theodore Roosevelt and others most of us have never heard of. Its creation was in response to threatened extinction of the nation's buffalo, antelope, elk and other species that had already become locally or regionally extinct. This system is maintained by individuals who desire the continued ability to harvest fish and wildlife and are willing to pay user fees to finance the science and enforcement needed to guarantee that. While incomplete - it focuses only on species people want to harvest - it has been the backbone of the world's most successful fish and wildlife conservation program. A federal Endangered Species Act completes the program by addressing the species that would otherwise be ignored or even persecuted (wolves, grizzlies, pupfish, etc). While all other continents are seeing their wildlife continue to disappear despite protective legislation, most major wildlife species in the US and Canada are increasing both their numbers and range. You hear a lot of doom and gloom from organizations who raise funds by peddling doom and gloom, but the truth is that conservation is working better in the US and Canada than anywhere else on the planet.
A key element of the system's success is giving everyone a stake in seeing that the regulations are followed and incentivizing all participants to be volunteer fish and game wardens by reporting violators. Cheaters are stealing from everyone because everyone shares ownership of the resource. While Robin Hood can shoot the King's deer and keep the approval of the peasantry, he ought not be a game hog with the PEOPLE's deer lest the sheriff gets a tip that Robin needs to be watched closely.
I see at least 3 obstacles to transplanting this system to Mexico. In the case of land animals, Mexico has bought into the European tradition that wildlife belongs to the landowner. That's hard to break, and US wildlife biologists working with Mexican biologists have not had much success selling the concept of public ownership of all wildlife. But that obstacle doesn't exist as far as I know in the Sea of Cortez where land ownership shouldn't come into play. What remains as obstacles is a probable lack of confidence that regulations would be enforced, and the lack of a political lobby demanding science-driven regulation.
Just a few years back the redfish along Louisiana's shoreline nearly became extinct from commercial harvest after a certain culinary celebrity made blackened redfish hugely popular and the nation's restaurants were clamoring for it. The Louisiana Sportsmen's Association succeeded in restricting redfish harvest to sport harvest only. Now if you want blackened redfish you'll need to go catch one. That's the kind of grass roots influence that's needed.
But unless people believe regulations will be enforced, they won't follow them. I believe the biggest challenge is in building confidence among the pangueras and other commmercial fishermen that regulations will be enforced and that the program will work if they do their part.
