Q. We know that aquatic mammals communicate with one another, but what about fish? A. Fish have long been known to communicate by several silent mechanisms, but more recently researchers have found evidence that some species also use sound… (NY Times)

Here’s another from Bruce Kirwin’s great collection of sea-life at Point Hudson, in Port Townsend. This jetty is slated for demolition and rebuilding in 2016, due to age and condition. The dive community is hoping to work with the Port to mitigate the consequences to underwater creatures such as this.

A good quick overview on why forage fish are important and why so many organizations are working on protecting the near shore.

Sometimes government agencies get it wrong. This is one of those times. Now we, the consumers, have to continue to just say no to farmed salmon, and demand wild fish. Only consumers can stop the industry, which has apparently manipulated through it’s lobbying efforts the highest levels of the FDA. This is a bad decision, for the environment, for consumers, and for fish. Why? It’s not that you might keel over by eating this fish. It’s about the entire ecosystem that is created to support this new animal. Have long term studies been done? I’ve not seen any. Has anyone questioned whether the feed and antibiotics that may be needed to support this creature are passed through to diners? Or what their effects on the environment might be under the pens that raise these? NOAA, which has certified these pens, only looks at the short term effects of the pens on the bottom directly under the pens. The science behind this is skewed in the favor of the farms, not the environment or the consumer.
Perhaps that last breed does not evoke images of ancient and frigid headwaters in Alaska or Arctic Canada, where wild salmon spawn every year, or even the humble hatcheries that produce less expensive species consumed by millions of people. But on Thursday, the Food and Drug Administration announced that the AquAdvantage salmon — developed using growth hormone from Chinook salmon and a gene from an eel-like ocean fish that makes it reach market size twice as quickly as other salmon — has become the first genetically engineered animal approved for American consumption. AquaBounty Technologies Inc., the Massachusetts company that created the fish, calls it “the world’s most sustainable salmon.” Opponents call it “Frankenfish.” The FDA, which was accused of delaying the decision for years amid public concern, now says you can call it dinner. William Yardley reports. (LA Times)

It seems to me that there has never been a clearer outcome of a study that allows us take simple action to save our salmon runs. Rain gardens anyone?
The long awaited study from the University of Washington on the toxic effects of stormwater runoff from roads is now complete. The study, which has been documented on this web site previously, showed that runoff captured from highway 520 near the Montlake Cut, was lethal enough to kill fish exposed to it.
Untreated highway runoff, collected in nine separate storm events, was universally lethal to coho relative to unexposed controls. Lastly, the mortality syndrome was prevented when highway runoff was pretreated by soil infiltration, a conventional green stormwater infiltration technology.
The study is found here https://www.documentcloud.org/documents/2451727-spromberg-et-al-in-press-j-appl-ecol.html
Longer story on it at the Seattle Times.

Good news that a more precise count on species has been completed. Will be good for future monitoring efforts.
Coho salmon, Pacific halibut and even the dogfish shark are familiar faces to many people in the Salish Sea region. But what about the Pacific viperfish, northern flashlightfish, dwarf wrymouth or the longsnout prickleback?
These colorfully named species and others are compiled in a new, 106-page report that documents all of the fishes that live in the Salish Sea, a roughly 6,500-square-mile region that encompasses Puget Sound, the Strait of Juan de Fuca, the Strait of Georgia, the San Juan Islands and the Canadian Gulf Islands.
In total, 253 fish species have been recorded in the Salish Sea, and that’s about 14 percent more than in the last count, said Ted Pietsch, co-author of the new report and a University of Washington emeritus professor of aquatic and fishery sciences.
