It's because of state regulations banning fishing from certain coastal areas.
The city's fish and game commission is closing a 7-mile stretch of the coastline to fishing and lobster-fishing.
The affected area is just north of El Moro to just south of Treasure Island and goes out 3 miles.
A councilman says commercial-lobster fishermen will lose 30 to 40 percent of their income when the ban begins on October 1.
