It’s 2020 and aquarists just discovered how to breed seadragons in-house: a combination of proper lighting, noise, tank size, and more. 

White abalone shells ​are​ magnificent structures. Translucent during the marine snail’s juvenile days, the extremely durable shell increases in opacity as the organism ages, gaining its paint-splatter-esque red, brown and white coloring from the algae it eats.

The California Department of Fish and Wildlife (CDFW) and National Oceanic and Atmospheric Administration (NOAA) Fisheries biologists are pursuing urgent measures this fall to save some of the last remaining Central Valley spring-run Chinook salmon after the numbers returning from the ocean this year fell sharply toward extinction.

Beds of eelgrass (Zostera marina) form an important habitat in coastal regions throughout the northern hemisphere, crucial to many fish and other species and storing vast amounts of carbon. A new study published July 20 in Nature Plants shows that eelgrass spread around the world much more recently than previously thought, just under a quarter-million years ago. The results have implications for how eelgrass could be affected by a changing climate.

While the wettest storm season in California’s recorded history crushed roofs and swelled snowbanks in the Sierra Nevada, the state’s coastal communities suffered plenty of their own losses. The casualties included waterside businesses swamped by storm surges, fishing piers smashed by rising seas, and coastal roads collapsed by debris flows.

Four sea otters that stranded in California died from an unusually severe form of toxoplasmosis, according to a study from the California Department of Fish and Wildlife and the University of California, Davis. The disease is caused by the microscopic parasite Toxoplasma gondii. Scientists warn that this rare strain, never previously reported in aquatic animals, could pose a health threat to other marine wildlife and humans.

People often say things like Phoenix has always been dry; Seattle has always been wet; and San Francisco has always been foggy. But “always” is a strong word. 

All seven of the United States’ abalone species that live on the West Coast are listed as Critically Endangered or Endangered according to the International Union for Conservation of Nature, or IUCN, Red List of Threatened Species. This is the first global Red List assessment of the species. The West Coast listings were based on an abalones assessment led by Laura-Rogers Bennett of the California Department of Fish and Wildlife, or CDFW, and University of California, Davis.
