The Magnuson Act: It’s a Keeper – Commentary

Two recent articles have come out based on a paper co-written with one of our board members, Suzanne Iudicello, and our Director, Brad Warren. This is the first article.

Healthy oceans and well-managed fisheries improve coastal economies, enhance recreational fishing opportunities and provide fresh, local seafood to consumers. And while many fisheries around the world are in serious decline, the United States benefits from one of the most sustainable and profitable fisheries management systems in the world. It is a system that is built on sound science and incorporates strong local input from fishermen and others. Under current law, our management practices are rebuilding many depleted stocks of fish and ensuring a sustainable fishing future for fishing communities long struggling with a variety of economic and environmental challenges.

The Magnuson-Stevens Fishery Conservation and Management Act, introduced in 1976, which has been at the center of much of this progress, is presently before Congress for reauthorization. Initially, the law used subsidies and other programs to provide access to and manage what was perceived as a near-limitless supply of fish. Over time, however, many of our iconic fisheries — such as the New England cod and Gulf of Mexico red snapper — became severely depleted. In response, fishermen, conservation groups and congressional leaders came together in 1996 and again in 2006 to improve the law and protect our fishermen’s livelihoods. These changes formed the foundation of our current sustainable fisheries management system.

As former directors of the National Oceanic and Atmospheric Administration’s Fisheries Service, we were both fortunate to have been present and helped implement these key bipartisan reforms to the Magnuson Act. These reforms have demonstrably improved the health of our oceans, sustainability of our fish stocks and the viability of many local fishing economies. We especially appreciate the hard work of fishermen, regional fishery managers, scientists, and conservation groups who continue to implement these policy advances on the water.

Overfishing (catching fish faster than they can reproduce) is now at an all-time low, and both 2011 and 2012 saw record recovery of depleted fish stocks. A recent status report detailed a total of 34 species have been returned to healthy levels in the past 13 years, including scallops, whiting and king mackerel. All fish populations in the United States are now managed under science-based plans. The act also has safeguards against overfishing and long-term depletion. And we know these plans are working: Recent analysis shows that 90 percent of fisheries have successfully stayed within science-based catch limits.

East Coast’s First Ocean Acidification Bill Becomes Law

Maine Legislature Press Release April 30th, 2014

AUGUSTA – The East Coast’s first measure to address the threat of ocean acidification became law Wednesday.

“Maine is taking the lead on ocean acidification on the Eastern seaboard. We understand just how dangerous it is to our marine environment, jobs and way of life,” said Rep. Mick Devin, D-Newcastle, the bill’s sponsor and a marine biologist. “We will address this threat head-on and find ways to protect our marine resources and economies.”

LD 1602 became law without the signature of Gov. Paul LePage. It went into effect immediately.

The measure would establish a commission to study and address the negative effects of ocean acidification on the ecosystem and major inshore shellfisheries. The committee membership would be made up of stakeholders including fishermen, aquaculturists, scientists and legislators.

“We who work on the ocean observe the day to day effects of small changes in climate and the destruction caused by such things as ocean acidification,” said Richard Nelson, a fisherman from Friendship. “We are solely dependent on a resource that must be managed intelligently and effectively in order for it to remain healthy and available to us.”

Rising levels of carbon dioxide from fossil fuel use are causing changes in ocean chemistry. As carbon dioxide and seawater combine, carbonic acid forms. Carbonic acid can dissolve the shells of shellfish, an important commercial marine resource. Over the past two centuries, ocean acidity levels have increased 30 percent.

If left unchecked, ocean acidification could cause major losses to shellfisheries like clams, oysters, lobsters, shrimp and sea urchins and put at risk thousands of jobs and billions of dollars to the state’s economy.

“We’re glad to see Maine leading on this issue,” said Rob Snyder, president of the Island Institute, which helped draft the legislation. “The industries that will be affected by ocean acidification employ thousands of Mainers – especially in island and coastal communities – and they contribute $1 billion to our state’s economy. It’s critical to learn more about the solutions to ocean acidification that will protect those jobs.”

Shellfish hatcheries on the West Coast have failed in recent years due to 60 to 80 percent production losses caused by ocean chemistry changes, which can take place quickly. A 2007 study by the National Oceanic and Atmospheric Administration discovered changes in ocean chemistry not expected for another 50 to 100 years on the West Coast.

Devin’s bill is one of the key legislative issues of the Environmental Priorities Coalition this year. The coalition cited research that found the Gulf of Maine is more susceptible to the effects of ocean acidification than other parts of the East Coast.

How Ocean Acidification Impacts Lobster Larvae

Maine School of Marine Sciences, by Ian Jones, April 15th 2014

Third-year marine sciences major  Ian Jones of Canton, Conn., is studying how ocean acidification impacts lobster larvae, an important resource for the Maine economy.

Jones works with American lobsters raised at UMaine’s Aquaculture Research Center (ARC). The lobster larvae were raised last summer at various pH levels, replicating natural environments and the impact of ocean acidification. Jones weighed and photographed approximately 700 lobster larvae to monitor their growth in these different environments. The hypothesis: slower growth and more irregular development occur at lower pH. This creates adaptation problems for lobsters dealing with increased environmental CO2 levels.

“We will certainly see greater ocean acidification in the future as an effect of climate change. As atmospheric levels of CO2 continue to increase from human input, so do the CO­2 levels of the upper ocean,” says Jones.

Along with lobster larvae, Jones also monitored seahorses in Tim Bowden’s lab. The seahorses, which were dealing with a mycobacterial infection, were in the care of Jones while an antibiotic treatment was created. He also raised juvenile seahorses last year. Through this experience, Jones learned about seahorse aquaculture, proper feeding protocols, tank chemistry and more.

“Not much is known about seahorse aquaculture relative to raising other fish, so although information on raising newborns was limited, it was a fun challenge figuring out our own system that worked.”

This fall, Jones will travel to the Darling Marine Center on the Damariscotta River, where he and other UMaine students will further the hands-on work they do in the classroom through the Semester By the Sea program.

Jones plans to attend graduate school to study sensory biology and/or the effect of climate change on marine animals.

Why is your lobster research important? Research on American lobster growth at lowered pH is incredibly important first, because there has been little climate change study on this particular species and second, any slowing or other adverse effects on lobster growth could have serious impacts on the health of the lobster fishery, which Maine, of course, greatly depends on. Delayed lobster larvae development means it will take longer for lobsters to get to market size, and predation risk may increase as well, causing fewer individuals to grow into adults and lowering the overall abundance of adult lobsters. Changes in lobster abundance can in turn upset ecosystem balance by changing the abundance of organisms that depend on lobster as prey and organisms lobsters prey on. These trophic cascades have the power to reduce the presence of many species in addition to just the lobster, consequently reducing biodiversity.
