I was impressed with the middens I have seen all along the Sea of Cortez. The hunter/gatherers were a busy lot. Some places I have seen are ten or
more feet deep. Sometimes in areas you would not expect them. Like up high on bluffs where they had to haul it all up just to bring the edible parts
back to camp or village.
I can only imagine the wealth of sealife and the ease of collecting many types of shellfish. They were not depleting a resource mainly because they
would move on to another area thereby letting the former sites rehabilitate. Whether or not this was intentional is not known. In the last 50 years,
the US(and others) has done serious damage to to continental shelf by way of trawls or dragging. Here in the NW it is estimated that for an area
heavily dragged will require up to 100 years to bounce back to the same as its untouched condition. It is mainly due to the cold water environment. In
warmer climes the process of rejuvenation by natural repopulation is many times faster.
When discussing the loss of invertebrates in areas like Bahia de Concepcion, in all probability a lot of places could be repopulated and managed
successfully. It may also be possible and feasible to farm clams and other shellfish on a sustainable level as which is done extensively in Puget
Sound and in scattered operations for AK to So. Cal. I am curious as to any attempt at this in Baja. I have seen the grant allocations for some ejidos
and other groups handed out. see:

It could be very lucrative, especially with the more exotic sought after species.
