NOAA/NMFS seeks input on proposed sea lion removal at Willamette Falls

NOAA Fisheries is seeking public input on an application from the Oregon Department of Fish and Wildlife (ODFW) to remove, by lethal means if necessary, California sea lions preying on endangered and threatened salmon and steelhead at Willamette Falls on the Willamette River near Oregon City. The approach would be similar to the ongoing removal of sea lions preying on vulnerable populations of protected fish at Bonneville Dam on the Columbia River.  Under the Marine Mammal Protection Act (MMPA), each application NOAA Fisheries receives for removing problematic sea lions must undergo independent consideration. info, click here to read the story 08:36

D.B. Pleschner: Nearshore anchovy abundance not proof fishery is collapsing

Recently, Dr. William Sydeman of the Farallon Institute, published a study claiming that the abundance of anchovy near shore — especially in places like Monterey — is evidence that the population is collapsing. Sydeman’s logic is based on an old argument that collapsed populations always shrink inshore. But there’s one big problem with that theory — it’s unsupported by scientific evidence.,,,  The bottom line: environmental groups with an anti-fishing agenda are already gearing up to hot-box the Pacific Fishery Management Council in spring 2018, lobbying for a steep reduction in anchovy harvest limits, employing whatever colorful, sensational pictures they can paint. click here to read the story 20:58

State warns of sick, stranded sea lions on Oregon coast

Oregon wildlife and health officials are warning beachgoers to be aware of sick and stranded California sea lions at the coast and to keep their distance. Officials at Oregon State University’s Marine Mammal Institute said they’ve documented a leptospirosis outbreak. The bacteria can prompt sick or dying sea lions to strand themselves on beaches and can also pose a threat to dogs, livestock and wildlife, as well as people. click here to read the story 13:55

Sea lions hinder salmon conservation

California and Steller sea lions took a bigger bite out of last year’s salmon run than in any previous year, according to a new federal report. 2015 saw a bigger run, with more than 239,000 chinook and steelhead migrating past Bonneville Dam. That year, the total number of salmon that sea lions ate was he largest ever recorded. The Army Corps of Engineers recorded more than 260 sea lions eating more than 10,000 fish from January to June 2015. The 2016 salmon run was far smaller, but the sea lions’ appetite for salmon didn’t shrink much. They still ate more than 9,500 fish, nearly 6 percent of the run. That’s the largest share of the run eaten by the large marine mammals since Army Corps scientists started watching 15 years ago. Read the rest here 12:43

California sea lions suffering from brain damage caused by algal blooms

The thousands of sea lions stranded on California beaches every year may be suffering from brain damage caused by algal blooms, according to a study of animal behavior by UC Santa Cruz researchers. The wave of sick sea lions has baffled scientists and beach-goers, who find them weak, confused or trembling due to seizures. The research, presented Monday at the bi-annual Conference on the Biology of Marine Mammals in San Francisco, revealed evidence of poisoning by domoic acid, a toxin produced by naturally occurring marine algae.

Rep. Doc Hastings’ bill would protect salmon from California sea lions

Opponents of the bill argued that the Marine Mammal Protection Act already grants local authorities appropriate action to safeguard the local fish species, saying that there was no demonstrative threat that numbers of the salmon population were falling below what was acceptable by the National Oceanic and Atmospheric Administration. Advocates of the bill, including Hastings, argued that the bill was a proactive measure that would build on previous methods which he said have been proven effective. [email protected],com

Starved for attention, Captain Paul Watson: The Damn Hunger Games on the Columbia River

Sea Shepherd is proud to announce the launch of the 2013 Dam Guardian campaign to protect California sea lions along the Columbia River in Washington and Oregon. This marks the second year Sea Shepherd has organized a sea lion defense campaign along the Columbia. This season Sea Shepherd has amassed plans to maintain a formidable presence at the Bonneville Dam and the Astoria trap site with a team of more than 30 international volunteers presently scheduled to participate on site. Below is a commentary by Captain Paul Watson originally posted on May 31, 2012. continue
