I'll believe it when I see it.
Presently, it is illegal in the Sea of Cortez for commercial fishermen to:
1) set long lines within 5 miles of shore (and yet every time I leave harbor, the first 30 minutes of the trip is like a pinball game with all the soda-bottle "buoys" that mark the long lines)
2) Commercial fish within 5 miles of any island in the SOC (and yet Isla San Jorge is swarmed by pangueros every time we are out there)
3) Collect more than 200 pounds of benthic invertebrates (clams, scallops, etc) per boat, per day (and yet this past year, for 3 solid months, there were pangas coming in that were so heavy with bags of scallops that they were in real danger of swamping, and at least 5 local scallop divers died this year due to poor dive practices)
4) Possess any specimens of Totoaba Macdonaldi (and yet the locals still insist on calling juvenile Totoabas "Mochorro", and insist that they are a different species that is legal for harvest - It is very common to see juvenile Toto's mixed in with other "Corvinas" in the fresh fish case at markets around Phoenix.
*** Now, to be fair- I personally think the no-possession law on Totoaba is stupid, since you never know what species is going to eat your jig, bait, etc; and when a fish comes up from more than about 150 feet deep, it's pretty much dead when it reaches the surface. The "no possession" law on Toto's should really be a "no targeted commercial harvest" law, in my opinion. ***
Desgarpa exists to set policies that give the APPEARANCE that the Mexican government is actively addressing commercial over-harvest activities in the Sea of Cortez. Desgarpa's enforcement arm is geared more toward agriculture than fisheries.
Conapesca exists to make sure that commercial, recreational and sport fisherman are buying their permits every year. Conapesca is little more than a revenue generating authority for the Mexican government.
These are the extent of fisheries "management and enforcement" in the Sea of Cortez, but awareness is the first step toward reconciliation.
