Study shows dramatic shift in marine species
FRISCO — Biologists looking at 40 years of fisheries data from Puget Sound have documented a dramatic shift in marine species. Key fish in the food chain, like herring and smelt, have declined, while the number of jellyfish has increased exponentially, to the detriment of the marine ecosystem.
“On land people see the changes that come with human population increases, but underwater the changes are much harder to discern,” said Correigh Greene, with NOAA Fisheries’ Northwest Fisheries Science Center. “What this tells us is that when you look over time, you can see that the underwater landscape of Puget Sound is changing too,” said Greene, lead author of the new study published in Marine Ecology Progress Series.

Environmental study for Pacific Ocean military exercises violates several federal laws
By Bob Berwyn
FRISCO — A federal court this week rejected a U.S. Navy plan for training activities off the coast of California and around the Hawaiian Islands after finding that the naval exercises would harm multiple species of marine mammals — in violation of the Endangered Species Act and the Marine Mammal Protection Act.
The plan, sanctioned by the National Marine Fisheries Service, fails to meet basic requirements of federal environmental laws, said Judge Susan Oki Mollway, of the U.S. District Court for Hawaii, calling the government’s documents so fundamentally flawed that they need to be totally rewritten.

Petition would end targeted fishing, lower incidental take limit
FRISCO — After decades of short-sighted exploitation by commercial fishing outfits, Gulf of Maine cod are at the brink of “commercial extinction,” according to conservation advocates who this month petitioned the National Marine Fisheries Service today to end targeted fishing of the species.
The petition also seeks to cap the incidental catch limit at 200 metric tons. The once-plentiful fish have declined 90 percent since 1982, when monitoring began, and 77 percent in the past five years. Currently Gulf of Maine cod are at 3 percent to 4 percent of what a well-managed stock should be, the petition asserts. Continue reading

With more offshore drilling on tap, regulators need more information to protect marine life
FRISCO — Along with a few small pockets of ocean already protected for marine mammals, biologists say there are hundreds of other areas that should be considered biologically important when making management and regulatory decisions about human activities that could affect whales, dolphins and porpoises.
The creation of Biologically Important Areas (BIAs) are described in a special issue of the journal Aquatic Mammals. Expert judgment was combined with published and unpublished data to identify 131 BIAs covering 24 species, stocks or populations in seven regions of the U.S. Continue reading

Whales and sea turtles hit especially hard
FRISCO — Not long after researchers managed to quantify the unbelievable amounts of plastic waste going into the world’s oceans, another team of scientists at Plymouth University said they’ve traced how many species are affected by the debris.
In all, nearly 700 species of marine animals have been recorded as having encountered man-made debris such as plastic and glass, the scientists said after looking at records of 44,000 animals and organisms that became entangled in, or swallowed debris. Continue reading

Seafood imports to U.S. must meet high marine mammal protection standards
FRISCO — In what conservation advocates are calling a landmark settlement, the U.S. government this week agreed to implement a long-ignored provision of the Marine Mammal Protection Act that will require foreign fisheries to meet the same standards required of U.S. fishermen or be denied import privileges. Continue reading

Do you know where your plastic shopping bag ends up?
‘It is alarming to find such high levels of contamination, especially when the full effect of these plastics on the delicate balance of deep sea ecosystems is unknown’
FRISCO — After researchers found plastic litter even in some of the remote reaches of the Arctic Ocean a few years ago, it’s probably not surprising to learn that the deep sea is becoming a collecting ground for plastic waste.
Floating mats of plastic have become a breeding ground for bacteria that could bring invasive pathogens to the open sea, and in another study, researchers documented how crabs are ingesting plastic through their gills.
A new study, published this week in Royal Society Open Science, shows how plastic debris breaks down into microfibers that are piling up in the deepest parts of the sea. The scientists with the Plymouth University and Natural History Museum say there could be around four billion microscopic plastic fibers could be littering each square kilometer of deep sea sediment around the world.
