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. 🦀🐋

Pop-up fishing technology aims to keep whales safe while letting fishermen get back on the water says @KSBW. @oceana’s @GeoffShester says authorization of this gear by @CaliforniaDFW for spring 2026 would be a win-win for fishermen and #WhaleSafeOceans https://t.co/QEidQNxgEr

"You could essentially be eliminating huge ecosystems without even understanding what was there in the first place," @Oceana’s @GeoffShester tells @PNS_News over impacts of deep sea mining ⛏️🪸 https://t.co/aLjIStb85l

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

A marine sanctuary off California's southern coast has helped foster a natural mecca for marine life. But the haven — and much of the rest of the ocean — is threatened by commercial fishing nets. https://t.co/xQZ5oXo1Fd

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: https://t.co/tCB1Qe6pZM

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.

[Oceana Pacific @Oceana_Pacific]

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 @OPC_California for supporting this investment 👏🐳🦀https://t.co/1TIhmpSRk6

[Oceana Pacific @Oceana_Pacific]

Thank you @asmstevebennett 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 https://t.co/ZjW7wwN3pM

WATCH: California ocean biodiversity at risk. Mile-long set gillnets targeting California halibut & white seabass entangle, injure, & kill more than 125 different species of ocean animals. @CaliforniaDFW we need you to address this needless waste to #KeepCAOceansThriving

[Oceana Pacific @Oceana_Pacific]

Great coverage by @suzannerpotter 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

California ocean biodiversity is at risk according to a new report by @oceana and @SeaTurtles_org. 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 https://t.co/g7Jw3XaxQU

“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 @GeoffShester Thank you @CaliforniaDFW https://t.co/YMdIywAmah
