The situation is similar in Subic, a town 55 miles (88 km) south of Masinloc. It used to host one of the biggest American naval bases outside the United States, before it closed in 1991.
Operators of the fishing market on the outskirts of the town of 90,000 say business is down 50% since the fishermen were blocked from fishing where they wanted to at Scarborough. Many fishermen here share a similar story to their counterparts further north.
"When we went there, a Chinese vessel, the Chinese Marine Surveillance blocked our path," says Ronnie Drio, 46-year-old father of eight children. "As we managed to get past through it, it looked like they called another one because a different ship appeared and blocked our way again.
"That's when we got trapped. Then a Chinese man stepped out. He looked like their highest officer. He flashed a sign that we had to leave immediately. We were kicked out like pigs."
A number of fishermen have already left Subic and Masinloc and many more are considering it. One of them, 58-year-old Tolomeo "Lomi" Forones, is Efren's cousin. He's been a fisherman for 30 years but now makes a living as a motorbike taxi driver. He makes around $2 on a good day.
"Our income was higher when we used to fish at Scarborough. I even used to save money. But now we earn just enough for daily consumption and sometimes what we earn is not even enough to provide food."
He still does occasional fishing trips but against his wife's wish. Janet Forones wants to leave Masinloc and their low income is not the only reason: "Who would not get worried when they are out there? What if they get shot?" She was referring to the presence of the Chinese boats.
What puzzles the fishermen here most is the speed the whole situation has changed. Although the Philippine and Chinese governments have disputed each other's claim to the lagoon for many years, they could fish at Scarborough alongside Chinese fishermen up until a few months ago.
"I do not know why they don't like us or why they do not want us within that area. If Americans were still in the region, the Chinese would have never came to Scarborough because they would be scared. If our government allows the U.S. to come back over here, its OK with me," she says, referring to Washington's commitment to its mutual defense treaty with the Philippines that former Secretary of State Hillary Clinton reaffirmed last year.
But the solution to the dispute is as distant as ever. Litigation at the United Nations could last years. Most of the local fishermen do not have so much time. So while the governments squabble, many of these fishermen and their families will have to leave the only life they have known and start from scratch somewhere else.
