A commercial shrimp trawler is pursued by three Sea Lions near San Felipe.
Shrimp trawlers, often entering into marine reserves illegally, pose a great threat to the marine environment at the northern end of the Gulf of California, due to the variety of marine wildlife, including Sea Lions that get caught in their bottom-trawling nets.
The Greenpeace vessel 'MY Esperanza' is currently in Mexico to highlight the threats to the 'world's aquarium' from over-fishing, destructive tourism development, pollution and marine habitat loss.
