MAINE: Costs, fish, property values are factors in the future of 3 Mousam River dams

December 29, 2015 — KENNEBUNK, Maine — A Kennebunk electric utility is weighing whether to remove the three lowest dams on the Mousam River or face potentially costly upgrades to restore fish passage to a river that once hosted large runs of spawning fish.

Trustees at Kennebunk Light & Power District have until March 2017 to decide whether to seek federal relicensing of three dams that the nonprofit utility owns on the Mousam River or propose several alternatives for the facilities. One option under serious consideration – and being pursued by local conservationists and sportsmen – is the removal of some or all three of the dams, including the large Kesslen Dam located in the heart of downtown Kennebunk.

The Mousam River is the only major river system in Maine emptying into the Gulf of Maine that lacks any methods for fish such as American shad, alewives or Atlantic salmon to bypass the dams, effectively blocking them from accessing more than 300 miles of watershed. Removing the three dams would allow the lower 9 miles of the Mousam River to flow freely – although an additional 12 dams remain on the upper stretch of river – and is part of an intense river restoration push in Maine.

Ocean acidification poses threat to lobsters

December 18, 2015 — PROVIDENCE — Lobsters are already slowly moving out of southern New England as waters warm, but the iconic crustacean faces another future threat as the climate changes.

As oceans absorb more carbon and become increasingly acidic, juvenile lobsters likely will have a harder time growing and forming strong shells to protect them from predators, according to a recent University of Rhode Island study.

“I’m not sure yet what the mechanism is that is affecting their growth,” URI doctoral student Erin McLean, who led the research, said. “But it takes energy for them to regulate the increased acidity, which is energy they cannot then put toward growth.”

And it’s not just lobsters that could be harmed by the oceans’ changing pH levels. Shellfish populations in Rhode Island and Massachusetts in general are among the most vulnerable in the United States to ocean acidification, according to a recent study in the journal Nature Climate Change.

The study identified the two states among 15 at-risk areas in the nation because colder, northern waters, such as Narragansett Bay, Buzzards Bay and Nantucket Sound, are absorbing more carbon dioxide from the atmosphere and acidifying faster than warmer waters.

Other more localized factors are also playing a part, including nutrient pollution from fertilizers and sewage systems that can add more carbon to the water and the flow of fresh water from poorly buffered rivers, such as the Blackstone in Rhode Island or the many waterways that drain into the Gulf of Maine, which lack minerals to mitigate the effects of acid. Shallow coastal waters also are more susceptible to changes in the ocean’s chemistry.

About a quarter of all carbon emissions from power plants, cars and other sources are absorbed by the oceans, making them more acidic and reducing carbonate levels. Shellfish use carbonates to make their shells, and when fewer of the compounds are available, organisms must expend more energy to build shells and less on eating and survival, researchers say.

Does fishing have a future in New England?

December 22, 2015 — Cod have been disappearing from the waters between Massachusetts and Maine, and shrimp populations are so depleted that the commercial shrimp season in the Gulf of Maine has been cancelled for the last three years.

At the same time, lobster are flourishing — alongside a host of species that have never before thrived in New England waters.

Why the wild ups and downs? One reason is that nearby waters are warming much faster than the rest of the ocean, making the environment newly unbearable for some longtime residents — and newly appealing for others. But overfishing has played a role as well, disrupting the balance of the watery ecosystem in unexpected ways.

It’s hard to predict where all this is headed, whether for individual species or local fishing communities. But it needn’t be a story of doom and gloom. These undersea changes may well dampen the prospects of the cod industry, but they will also bring new opportunities.

What’s happening in nearby waters?

Rapid and unusual warming.

Temperatures in the Gulf of Maine have been increasing faster than just about every other blue spot on the planet. According to a recent report in Science, Maine’s waters are in the top 0.1 percent when it comes to rapid warming.

While that team focused on the waters to the east and north of Massachusetts, that superwarm area they reported on actually extends significantly south, surrounding the Bay State.

Fish food for thought: New research affects catch limits

December 21, 2015 — PORTLAND, Maine (AP) — What happens when a fisherman tosses a fish back overboard?

It’s not a frivolous question. The government bases catch quotas and other rules in part on the mortality of tossed fish, and there isn’t always accurate data available about how many fish survive the fling. Now, a group of New England scientists says it’s finding that a surprisingly high percentage of the lucky fish might live to swim another day.

Scientists with the New England Aquarium and other institutions want to help the fishing managers get a better handle on what happens when cod, haddock and cusk get thrown from a fisherman’s line back into the sea. The first round of their research, on the imperiled Gulf of Maine cod, found that 9 to 21 percent of the fish died, better than the 30 percent estimate regulators had been using.

That data could help change quotas for recreational fishermen, who like their commercial counterparts must abide by strict limits on some species.

“We found that mortality rates are pretty low,” Dr. John Mandelman, the New England Aquarium’s director of research and a co-leader of the study. “Generally, in the past, they’ve used really conservative estimates.”

Off the hook – Researchers find mortality of cod caught and released off Gloucester is half of original estimate

December 21, 2015 — With cod at historically low population levels and commercial fishermen limited to landings that are just a fraction of what they once were, the recreational catch is now believed to account for as much as one-third of total landings of Gulf of Maine cod.

But recreational landings data was considerably poorer than the commercial data, which made it hard to estimate their true impact on the population or know the effectiveness of regulatory measures.

Solving the cod crisis will take a lot of research. Now, scientists are no longer restricted to their lab. As a recent study shows, creative thinking and technology can turn the ocean into a lab, and the results can be more precise and minimize the regulatory impact on fishermen.

A key missing piece in the puzzle was information on how many fish died after they were released by anglers. Lacking key data such as length and weight of released cod resulted in the assumption that 100 percent of those fish died. Missing data can lead to underestimating the population size, with overly strict regulations, said Michael Palmer, National Marine Fisheries Service research fishery biologist.

Researchers started collecting length and weight data in 2005 after regulators tightened reporting requirements for recreational fishermen. In 2011, a panel arrived at a consensus that 30 percent of cod released by anglers died. But Palmer was concerned that there were no directed studies, in the U.S. or internationally, to truth-test the estimate.

Shrimpers wanted for research program

December 19, 2015 —  The Atlantic States Marine Fisheries Commission is closer to embarking on its planned sampling program for the endangered Gulf of Maine northern shrimp stock and is looking for trawl and trap vessels to help collect shrimp and data.

The commission, which hopes to begin the test-tow portion of the the program in mid-January and the trap portion about a month after that, is looking for a total of four trawl vessels and two trap vessels from New Hampshire, Maine or Massachusetts, according to Tina Berger, spokeswoman for the ASMFC.

Anyone interested in participating in the project should contact Maggie Hunter at the Maine Department of Marine Resources by Jan. 4.

The $10,000 program is designed to catch the northern shrimp, Pandalus borealis, while they are in inshore waters to collect data on the timing of the egg hatch, as well as the size, gender and development stages of the shrimp.

The vessels will be expected to fish approximately once every two weeks until the shrimp no longer carry eggs, which Berger estimated will be some time near the end of March.

NEMFC Newsletter, December 2015

December 17, 2015 — The following was released by the New England Fishery Management Council:

Framework Adjustment 27

At its early December meeting, the New England Council finalized its recommendations for Framework 27 to the Atlantic Sea Scallop FMP. The action contains catch specifications for the 2016 and 2017 (default) fishing years.

Fishermen will receive allocations that are projected to result in landings of about 47 million pounds of scallops in 2016. Forty million pounds are allocated to the scallop limited access fleet. Of the remainder, about 4.5 million pounds are allocated to the limited access general category (LAGC) fishery which numbers about 100 active vessels, and about 800,000 pounds are reserved for the observer set-aside program.

Several other specifications are the same as fishing year 2015 — 1.25 million pounds for the research set-aside program, 70,000 pounds for vessels with Northern Gulf of Maine LAGC permits, and 50,000 pounds for vessels with incidental LAGC permits.

Compared to 2015, the approximately 340 active limited access vessels will be allocated slightly more days-at-sea (DAS) in open areas this year and the same level of effort in the Mid-Atlantic Access Area (Delmarva, Hudson Canyon and Elephant Trunk Areas are combined in this action).

The proposed allocations for limited access vessels, as approved by the Council, will be 34.55 open area days-at-sea (as opposed to 31 DAS in 2015) for full-time vessels and 51,000 pounds in the Mid-Atlantic Access Area. Part-time vessels will receive 13.82 days-at-sea and 20,400 pounds in the Mid-Atlantic Access Area.

After much discussion, the New England Council also would allow a portion of the total LAGC allocation to be taken from the northern part of the Nantucket Lightship Access Area. The maximum removal from this relatively small area is proposed at 300,000 pounds, or about 7% of the LAGC total allocation. The proposed action also prohibits any scallop vessel from undertaking research set-aside compensation trips in the Lightship Area. The LAGC fleet’s total allocation from the Mid-Atlantic Access Area is 1.2 million pounds. Both areas would be closed to these vessels once the fleetwide LAGC quota is reached.

Warmer waters affecting the New England fishing industry

December 9, 2015 — A new study has found the Gulf of Maine is warming faster than almost every other ocean in the world. For the first time, it links warming sea temperatures to the collapse of cod stocks in the region.

For Portland’s fishing community, the first hours of daylight are the most important. At the town’s fish exchange, boats rush to unload their catch, ready to be sorted, and sold.

They are not just working against time.

Today’s landing at the Portland fish exchange was about 40,000 pounds worth. That’s not considered very much. Out of that, just seven boxes worth of cod; that’s about 500 pounds.”

Cod stocks have been declining here for decades. Federal quotas were slashed by 75 percent back in May, to help the species recover.

Now a new study suggests that intervention may have been too late.

Andrew Pershing, chief scientific officer at the Gulf of Maine Research Institute says, “You assume that if you pull back on the fishing, the stock will have the same productivity that it had in the past.  But our work really shows that the productivity in Gulf of Maine cod was declining pretty rapidly as the waters were getting warm and so by not factoring that in they weren’t able to rein in the quotas fast enough.”

Moratorium on Northern Shrimp Commercial Fishing Maintained for 2016 Season

December 8, 2015 — PORTSMOUTH, N.H. – The following was released by the Atlantic States Marine Fisheries Commission:

In response to the depleted condition of the northern shrimp resource, the Atlantic States Marine Fisheries Commission’s Northern Shrimp Section extended the moratorium on commercial fishing for the 2016 fishing season. The 2015 Stock Status Report for Gulf of Maine (GOM) Northern Shrimp indicates abundance and biomass indices for 2012-2015 were the lowest on record for the 32-year time series. The stock has experience failed recruitment for five consecutive years, including the three smallest year classes on record. As a result, the indices of fishable biomass from 2012-2015 are the lowest on record. 

Recruitment of northern shrimp is related to both spawning biomass and ocean temperatures, with higher spawning biomass and colder temperatures producing stronger recruitment. Ocean temperatures in western GOM shrimp habitat have increased over the past decade and reached unprecedented highs in 2011 and 2012. While 2014 and 2015 temperatures were cooler, temperatures are predicted to continue to rise as a result of climate change. This suggests an increasingly inhospitable environment for northern shrimp. The Northern Shrimp Technical Committee considers the stock to have collapsed with little prospect of recovery in the immediate future. The 2015 Stock Status Report is available at http://www.asmfc.org/uploads/file/5666017a2015NorthernShrimpAssessment.pdf. 

To maintain the time series of data collected from northern shrimp commercial fishery catches, a cooperative winter sampling program was approved with a 22 metric ton research set aside quota. The goal of the program is to continue the winter time series of biological data (e.g. size composition, egg hatch timing) collected from GOM northern shrimp fishery catches in the absence of a fishery.  Four trawl vessels will be contracted to fish four regions with a maximum trip limit of 1,800 pounds, and two trappers with a weekly trap limit of 40 traps and a 600 pound per week limit. Participating trawlers and trappers will be able to sell their catch.  Trawlers will also be compensated $500/trip. 

“Considering survey indices are the lowest on record, with an unprecedented five consecutive years of weak recruitment and continuing unfavorable environmental conditions, the Section maintained the moratorium in 2016,” stated Northern Shrimp Section Chair Mike Armstrong of Massachusetts. “The Section is committed to protecting the remaining spawning biomass and allowing as much reproduction to take place as possible.”
