Brad Warren & Julia Sanders: Washington’s Initiative 1631 will help fight ocean acidification

November 2, 2018 — We write today to announce our support for Washington’s Initiative 1631. As businesses who rely on healthy fisheries for a significant portion of our income, we believe this is a well-designed policy that offers us – and our customers – the best possible chance against an uncertain future fraught with the threats of changing ocean conditions.

It’s become clear that our fisheries need a lifeline. Here in Washington, we are experiencing the worst ocean acidification anywhere in the world. Research has firmly established the cause of this problem: emissions from burning coal, oil and gas mix into the ocean, altering its chemistry. The consequences loomed into headlines a decade ago when the oyster industry lost millions and nearly went out of business during the oyster seed crisis. Temporary and limited adaptation measures in hatcheries are keeping them in business, but in the rest of the oceans, fisheries that put dinner on billions of tables are at risk. Here in the Northwest, harvests are already being eroded and even shut down by the effects of unchecked carbon emissions.

The “warm blob,” an unprecedented marine heatwave off the West Coast, reached its height in 2015 and caused mass fatalities. In the Columbia River, a quarter-million salmon died. The largest recorded toxic algae bloom shut down the Dungeness crab fishery for months. The food web crashed, and marine creatures were spotted farther north than ever before. Sea surface temperatures never returned to their previous norm, and new research indicates another blob is forming.

Summers have become synonymous with a smoky haze from wildfires causing poor visibility and poor health – this summer the National Weather Service warned even healthy adults in some Washington areas to stay indoors due to hazardous air quality. At the same time, our iconic orca whales are starving from a lack of Chinook salmon. The Chinook in turn are suffering from a lack of the zooplankton that juveniles eat.

Research has made it clear that some of our most lucrative fisheries are vulnerable to ocean acidification: king crab, Dungeness crab, and salmon. Scientists also warm that combining stressors – like warming with ocean acidification – makes survival in the ocean all the more precarious.

Copepods: Cows of the Sea

October 6, 2017 — If you look very closely at a glassful of water from a bay or the ocean, you would probably be surprised by the life inside. You might see miniature crustaceans the size of the period at the end of this sentence or baby crabs and fish that spend only a short span of their lives this small. These creatures are zooplankton, aquatic animals that drift with the currents.

It’s the Little Things 

These tiny animals form the basis of the food web of estuaries, coastal waters, and oceans. Zooplankton feed on microscopic plant-like organisms called phytoplankton, which get their energy from the sun. Tiny crustacean zooplankton called “copepods” are like cows of the sea, eating the phytoplankton and converting the sun’s energy into food for higher trophic levels in the food web. Copepods are some of the most abundant animals on the planet.

Fish such as anchovies cruise through the water with their mouths wide open, filtering copepods and other zooplankton from the water. Anchovies and other planktivores (plankton-eaters) are prey for bigger animals, like tuna, sharks, marine mammals, and seabirds.

Fishery Group Comes Out Against Seismic Surveys

June 23, 2017 — The New England Fishery Management Council is asking the Trump Administration to slow its push for offshore oil and gas developments on the East Coast.

An Executive Order signed in April urges oil exploration in the mid and south Atlantic. Currently, five companies are seeking permits to conduct what are called seismic surveys in these areas.

Those surveys fire powerful sound waves into the ocean floor. Then, surveyors listen to the echoes to detect oil reserves.

Scientists increasingly worry those sound waves disturb whales and fish. A study published this Wednesday in the journal Nature says the surveys kill off zooplankton, a cornerstone of the ocean food chain.

Thomas Nies is Executive Director of the New England Fishery Management Council. His organization has spoken out about the surveys, because of concerns they’ll affect fisheries here. “We’re concerned about seismic surveys. The council isn’t convinced that we have enough information on what their impacts are across a wide range of species.”

RHODE ISLAND: Fishing Report: Hearing on menhaden set for Dec. 19 at URI

December 8, 2016 — Atlantic menhaden are an important forage fish for striped bass, bluefish, tuna and other species. Recreational anglers claim that fishing for these game fish is off when the quantity of forage fish is down. Additionally, Atlantic menhaden are filter feeders with each fish processing thousands of gallons of water filtering out plankton to help prevent algae blooms.

So if you want to impact regulations pertaining to this species, now is the time to become active. There will be an Atlantic menhaden public hearing to talk about important Fishery Management Plan issues on Dec. 19 at 7 p.m. at the Corless Auditorium at the URI Bay Campus, Narragansett. The hearing will address a new Public Information Document that is a predecessor to Amendment 3 to the Atlantic menhaden Fishery Management Plan that will be developed later this year.

NOAA’s website says Atlantic menhaden “play an important role in the ecosystem as both a forage fish for striped bass, weakfish, bluefish, and predatory birds such as osprey and eagles as well as serving as a filter feeder because they feed on phytoplankton and zooplankton at various life stages.”

So rather than just managing Atlantic menhaden to ensure they remain sustainable as a species, the PID aims to include ecosystem-based management measures to ensure that enough Atlantic menhaden are left in the water for other species to eat as forage fish as well as enough to fulfill their ecological role.

Atlantic menhaden are plentiful. A 2015 stock assessment for the resource relates they are in good condition, not overfished nor experiencing overfishing. The PID can be found on the ASMFC website at www.asmfc.org. Public comments can be made at the hearing and will also be accepted in writing until 5 p.m. on Jan. 4, 2017. Comments can also be emailed to comments@asmmfc.org (subject line: Menhaden PID).
