Collapsing salmon runs and restrictions on Dungeness crab fishing have forced restaurants, charter boats, and commercial fishers in California's coastal villages to adapt.

The latest blows came in early April.

Commercial harvest of Chinook salmon was banned in California for the third consecutive year because of low populations, and the state's Dungeness crab fishery has been severely restricted in an effort to protect humpback whales from entanglements.

Entanglements have increased in the last decade following a change in feeding activity that has concentrated the animals closer to the California coast, especially from spring through summer.

Commercial crabbers are collaborating with environmental groups to develop whale-safe crab gear that involves no unintended vertical ropes in the water.

Abalone and the kelp forest they live in have also almost vanished, the victims of overfishing and climate change.

Now, coastal towns that once relied on freshly caught seafood are finding ways to adapt.

In Bodega Bay, fishing has increasingly taken a backseat to tourism and the draw of art galleries, saltwater taffy, waterfront dining, and vacation rentals.

A small fleet of party boat services keeps a presence in the harbor, but some boats are turning to cruises, whale-watching, and ash-scattering voyages to replace lost fishing opportunities.

Visitors to the town still expect seafood, and they still get it, but many menus feature products farmed or delivered from faraway waters, including clams, oysters, and shrimp.

While the community thrives on the bustling tourism economy, many residents and business owners are worried about the town's fishers.

Waves of Compassion is a local nonprofit that, among other things, helps struggling commercial fishers in and around Bodega Bay with food, clothes, laundry money, dog food, and other items that Patty Ginochio, a co-founder and the owner of Ginochio's Kitchen, says many increasingly cannot afford.
