Domoic acid is a naturally occurring toxin related to a “bloom” of certain single-celled algae.
Fish and shellfish are capable of accumulating elevated levels of domoic acid in their tissue, leading to illness if consumed by humans.
During late 2015 through early 2016, domoic acid along the West Coast interrupted Dungeness and rock crab fisheries from Santa Barbara to the Oregon state line.
The California Department of Fish and Wildlife (CDFW) and California Department of Public Health (CDPH) are working with the fishing community to collect crab samples from the northern California coast until the domoic acid levels have dissipated.

El Niño and La Niña Pacific Coast Effects
The projected upsurge of severe El Niño and La Niña events will cause an increase in storm events leading to extreme coastal flooding and erosion in populated regions across the Pacific Ocean, according to a multi-agency study published recently in Nature Geoscience.
“This study significantly advances the scientific knowledge of the impacts of El Niño and La Niña,” said Patrick Barnard, USGS coastal geologist and the lead author of the study. “Understanding the effects of severe storms fueled by El Niño or La Niña helps coastal managers prepare communities for the expected erosion and flooding associated with this climate cycle.”
New research data, from 48 beaches across three continents and five countries bordering the Pacific Ocean, suggest the predicted increase will exacerbate coastal erosion irrespective of sea level rise affecting the region.
Researchers from 13 different institutions, including the U.S. Geological Survey, University of Sydney, the University of New South Wales and the University of Waikato (New Zealand) analyzed coastal data from across the Pacific Ocean basin from 1979 to 2012.
The published paper, “Coastal vulnerability across the Pacific dominated by El Niño/Southern Oscillation” is available online.
