CALIFORNIA: Innovative fishing gear is being tested to reduce impact on whales and sea turtles

February 22, 2021 — A new collaborative project between environmental groups, the state, scientists, and Dungeness crab fishers is testing innovative new gear designed to reduce the impact of whales and sea turtles getting caught in fishing gear.

This is in response to California’s recent state regulations to reduce the risk of endangered whales and sea turtles getting caught in commercial Dungeness crab gear. The regulations went into effect last November, and when high numbers of humpback whales were sighted off the coast near San Francisco and Monterey Bay, the opening of the commercial Dungeness crab season was delayed by about a month.

Since 2014, the number of interactions between whales and fishing gear has been historically high. In 2019, for example, 26 whales were entangled off the West Coast, 17 of which were humpback whales.

“There’s a vertical line attached to the trap that goes to the buoys at the surface,” said Greg Wells of the National Marine Sanctuary Foundation who is managing the collaborative gear-testing research project. “That’s the part that poses an entanglement risk for whales and other marine life.”

Ropeless gear bill introduced in California statehouse

February 17, 2021 — A bill to require the use of ropeless pop-up gear in Dungeness crab and other trap fisheries by November 2025 was introduced into the California State Assembly on Thursday, Feb. 11.

Dubbed the Whale Entanglement Prevention Act, fishermen say the passage of such a law would be a death knell for the iconic and recently embattled Dungeness crab fishery. But at this point, there isn’t much fear among the fleet, as the bill could be dead in the water.

“I think we’re going to kill it,” said Ben Platt, a Crescent City-based fisherman and president of the California Coast Crab Association. “It’s not going to make it out of committee.”

Assemblymember Rob Bonta (D-Oakland) introduced the bill, AB-534, with two environmental organizations as cosponsors, Social Compassion in Legislation and the Center for Biological Diversity. The latter group filed a federal suit against the state of California in October 2017, arguing an increase in whale entanglements in the Dungeness crab fishery violated the Endangered Species Act.

The spike in whale entanglements from 2015 to 2017 has been attributed to climate change and an extreme marine heatwave that caused ecosystem shifts and habitat compression.

Scripps scientists to study effects of climate change on California coastline

December 27, 2018 — Four researchers at Scripps Institution of Oceanography have earned state grants to study how climate change is shifting conditions on the Pacific Coast, including cliffs and tide pools.

Together they were awarded $1 million from the California Ocean Protection Council to create maps, models and other data sources that will help chart the changes to California’s coastline, and guide strategies to deal with them.

The council was created in 2004 as part of the California Ocean Protection Act, and works to maintain “healthy, resilient and productive ocean and coastal ecosystems.” The grants of $250,000 to each scientist are part of a larger project to fund research on topics such as sea-level rise and coastal resilience, marine pollution and renewable energy.

Marine biology professor Ronald Burton will use “DNA metabarcoding,” a method of high volume genetic analysis, to identify fish eggs and determine which species are spawning from La Jolla to Santa Cruz. Jennifer Smith, an associate professor of marine biology, is building 3-D images of rocky intertidal zones to study how sea-level rise will affect the wealth of marine life in tide pools.

Scientist Adam Young will map the stability of coastal cliffs and detect “erosion hot spots.” And associate professor Brice Semmens will develop a time series of bass species abundance dating back to the late 1940s in order to guide management of the popular recreational fishery.

California Creates Plan to Curb Ocean Acidification

October 30, 2018 — California officials have created a plan to stop climate change from killing sea creatures and protect the state’s $45 billion ocean-based economy.

Deborah Halberstadt with the California Ocean Protection Council said the ocean is getting more acidic as it absorbs increased amounts of carbon dioxide, which can threaten species key to the fishing industry.

“With climate change we’re seeing warmer oceans. It’s actually changing the chemistry of the ocean water and making it more corrosive,” Halberstadt said. “This has the impact of potentially destroying the bottom layer of the food web.”

Concern began when oysters started dying in the Pacific Northwest.

“The animals can’t develop shells because the water is too acidic and so then they either die or become deformed,” said Halberstadt.

The state’s first California Ocean Acidification Action Plan will analyze and identify the full risk. State officials are worried about the Dungeness crab and salmon populations.
