The article highlights a potential economic threat to Mexican fishery companies, particularly those involved in the shrimp industry, due to the United States imposing a blockade on imports from the Upper Gulf of California. This action is in response to the Mexican government's failure to implement measures to combat illegal fishing and the mortality of the endangered vaquita porpoise. The ban was initiated following a 2018 lawsuit by environmental organizations and reinforces the need for comparability in fishing practices. If not addressed urgently, the ban could extend to other fish species and areas, severely impacting Mexican export revenues from shrimp, which make up 80% of total shipments.
