Thank you Luz Rivas Gavin Newsom Eleni Kounalakis Surfrider California Monterey Bay Aquarium for leading the charge to #DefendTheDeep. Vibrant and diverse living seafloor habitats like coral gardens, sponge beds, & rocky reefs will be safeguarded from destructive seabed mining bit.ly/3Bvb1B3

“When whales arrive off California in large numbers it’s heartening to know they will hopefully be able to find the food they need without the risk of becoming entangled in a fishing line,” says @Oceana's Geoff Shester Thank you California Department of Fish and Wildlife bit.ly/40MNBSL

California ocean biodiversity is at risk according to a new report by Oceana and TIRN. Mile-long set gillnets meant to catch California halibut and white seabass off SoCal are catching more than 125 different species of ocean animals. Read more bit.ly/43BTNPQ

CALIFORNIANS: Deadly set gillnets pose a constant threat to whales, sharks, sea lions, and other iconic California #ocean animals. 🦈 🐋 Don’t let wildlife continue to suffer! Add your name to tell California Department of Fish and Wildlife to #KeepCAOceansThriving: bit.ly/40mPqFG

Great coverage by Suzanne Potter on a threat to California's ocean biodiversity. New Oceana report finds mile-long gillnets fixed to the seafloor to catch California halibut & white seabass entangle more than 125 species of marine life. #KeepCAOceansThriving

Thank you Assemblymember Steve Bennett for championing #YesOnAB2220 to protect California’s ocean life from the threat of entanglement in set gillnets. These nets are 20 football fields long and threaten ocean biodiversity. Read more bit.ly/3UB8MYo

New funding will expand opportunities for California Dungeness crab fishermen using ropeless gear while protecting whales and sea turtles from entanglement. Oceana commends participating fishermen and California Ocean Protection Council (OPC) for supporting this investment 👏🐳🦀bit.ly/3uYUciI

Our oceans need #YesOnAB2220. Calif voters banned use of the type of monofilament net in nearshore waters seen entangled around this recently spotted gray whale. Yet, the gear is still allowed offshore SoCal where it can have consequences like this.

Help protect California wildlife this #BiodiversityDay!🪸 🦈 California's waters are home to an incredible array of wildlife, but these habitats & animals are threatened by indiscriminate fishing gears. Add your name to protect #biodiversity here today: oceana.ly/3KaBWXV

We can keep fishermen in business AND protect the resilience of our ocean ecosystems by using smarter, more selective fishing methods #WorldOceansDay

California wrapped up the most successful trial of pop-up fishing gear on the U.S. West Coast, proving this innovative gear to catch Dungeness crab is profitable for fishermen and safe for whales. 🦀🐋 Read more about the results 👉 bit.ly/46HZiRc

Pop-up fishing technology aims to keep whales safe while letting fishermen get back on the water says @KSBW. Oceana’s Geoff Shester says authorization of this gear by California Department of Fish and Wildlife for spring 2026 would be a win-win for fishermen and #WhaleSafeOceans ksbw.com/article/whale-…
