Many Young Fish Moving North with Adults as Climate Changes

October 2, 2015 — The following was released by NOAA Fisheries:

Numerous studies in the Northeast U.S. have shown that adult marine fish distributions are changing, but few studies have looked at the early life stages of those adult fish to see what is happening to them over time. A new study by NOAA Fisheries researchers has some answers, finding that distributions of young stages and the timing of the life cycle of many fish species are also changing.

Most marine fish have complex life histories with distinct stages, much like frogs. Marine fish spawn small planktonic eggs, approximately 1/20 of an inch in diameter, that move at the whim of ocean currents. These eggs hatch into larvae that have non-functional guts, un-pigmented eyes, and often don’t yet have a mouth. Over a period of weeks to months, while drifting in the ocean, larvae develop and grow until they reach a point where they transition into juveniles recognizable as a fish. This complex life history is similar to that of frogs, which grow from eggs to tadpoles to adult frogs.

The distribution of larvae in the sea is determined by where adult fish reproduce and by currents that move these small early life stages around the ocean. In a study published September 23 in the journal PLOS ONE, researchers from NOAA’s Northeast Fisheries Science Center used long-term survey data to compare the distributions of larvae between two decades, from 1977-1987 and from 1999-2008. They also used long-term survey data to compare distributions of adult fish over the same time period.

HARTFORD COURANT: Cost of Outdated Rules? Millions Of Dead Fish

September 21, 2015 — This is utterly crazy. Hundreds of thousands — perhaps even millions — of pounds of edible and valuable fish are being wasted every year, thrown overboard from commercial fishing boats off the Connecticut coast, due to long-outdated federal regulations that have not kept up with a changing climate and shifting fish populations.

The problem, as The Courant’s Gregory Hladky has reported, is that catch quotas for some species are based on where the fish were when regulations were created decades ago, not where they are today.

Take, for example, summer flounder or fluke. Catch quotas to protect and rebuild the species were set in 1990, based on data gathered in the 1980s. The concentration or biomass of the species was then off the mid-Atlantic coast, so North Carolina and Virginia fishermen got large quotas, 30 percent and 20 percent respectively, while Connecticut got 2.25 percent.

So too with black sea bass, for which Connecticut fishermen are limited to 1 percent of the commercial catch, about 22,000 pounds of black sea bass this year, while boats from North Carolina get to 11 percent of the total and Virginia fishermen get 20 percent.

NOAA Fisheries unveils climate science strategy

September 4, 2015 — As ocean conditions continue to change, putting ocean ecosystems and the communities that rely upon them at risk, NOAA took a first step in providing regional fisheries managers and stakeholders with information they need to reduce the effects of climate change and build resilience.

“NOAA just announced that for the globe the month of July — and actually, the entire year so far — was the warmest ever recorded, driven largely by record warm ocean temperatures,” said Eileen Sobeck, assistant NOAA administrator for fisheries.

“Those warmer waters – along with rising seas, coastal droughts and ocean acidification – are already putting people, businesses, and communities at risk. With this strategy, we’re taking a proactive approach in providing information on current and future conditions to try and reduce impacts and increase our resilience,” pointed out Sobeck.

The NOAA Fisheries Climate Science Strategy identifies seven key steps to increase production, delivery, and use of climate-related information to support the management of fish stocks, fisheries, and protected species. The steps focus on how a changing climate affects living marine resources, ecosystems, and the communities that depend on them, and how to respond to those changes.

Iconic fish species move north as ocean warms

September 6, 2015 — Warming ocean temperatures off the North Atlantic are causing fish to move up the coast to cooler waters — raising concerns among scientists and regulators about the ocean’s ecosystem, and potentially changing the experience Delaware anglers have enjoyed for generations.

In 2013, a Virginia Beach striped bass tournament drew hundreds of boats, but only one striper was caught.

Wachapreague, Virginia, a tiny town south of Chincoteague that called itself the “flounder capital of the world,” lost its identity and economic engine when summer flounder relocated to waters off the coasts of New Jersey and New York.

And the iconic blue crab, a staple of restaurants and dinner tables throughout the Delmarva Peninsula, are expanding their range, scuttling up the coast to Maine.

Striped bass, which gave birth to a charter fishing industry in Delaware, are swimming into deeper water during their fall migration through the mid-Atlantic — well beyond the 3-mile limit off the coast where it is legal to catch and keep them.

Black sea bass — once so common in area waters, they were the go-to-fish when other species weren’t biting — have moved north to New England.

DELAWARE ONLINE: Why are the fish moving north?

September 5, 2015 — Forget gloom-and-doom outlines. Forget too, simple denial. Something is happening and we should 1) take it seriously. and 2) do something about it. Even if the something we do is to start adjusting for enormous changes.

Sea levels are rising. We know that. It will slowly affect those who live near the ocean’s edge. It will affect commerce and travel as well. Consider that a New England scientist who found that blue crab living in the Gulf of Maine. He also found the blue crab are eating the green crabs. How will that affect the environment? What else is going on? And what will be the repercussions in the short- and long-term? We simply do not know.

In addition to the temperatures and the sea rise, we know we have overfished many areas and we have damaged habitat. All of these things could create conditions that we as of yet do not understand.

Rich Wong, a scientist with the Delaware Department of Natural Resources and Environmental Control, said, “It’s really small, incremental rises in temperature that have huge impacts.”

Experts Say Wasteful Fishing Regulations Not Keeping Pace With Climate Change

September 6, 2015 — Hundreds of thousands of pounds of valuable fish caught off Connecticut’s coast are thrown overboard every year, and 80 percent of them are dead by the time they hit the water, experts say.

Commercial fishermen, environmentalists and state officials say a prime reason for such a stunning waste of a natural resource is an out-of-date federal regulatory system that hasn’t kept up with the realities of a changing climate and shifting fish populations.

“It’s just a wholly unjustifiable practice,” said Peter Auster, a senior research scientist at Mystic Aquarium. “This waste … is pervasive in the way we’re managing fishing.”

“The whole construct of the [regulatory] system needs to be questioned,” said Curt Johnson, executive director of the Connecticut Fund for the Environment and Save the Sound.

The problem is that federal fishing regulations are designed to protect fish species based on where they used to be most plentiful. Some of those fish populations have now shifted their range north as a result of global warming, but federal fishing quotas haven’t changed. As a result, Connecticut fishermen are saddled with low, out-of-date quotas, forcing them to throw back huge amounts of certain species, even though those fish have become plentiful off New England.

Warming Oceans Putting Marine Life ‘In a Blender’

September 3, 2015 — Up in Maine, lobsters are thriving. The Atlantic States Marine Fisheries Commission reported last month that stocks there reached a record high.

Down the coast, however, the story is different. In southern New England, lobster stocks have plummeted to the lowest levels ever recorded, putting many lobstermen out of business.

Lobster populations rise and fall for many reasons. But in its new report, the commission singled out one factor that is probably driving the recent changes: The ocean is warming.

At the northern edge of the lobsters’ range, higher temperatures may be speeding up their metabolism, leading to the population boom. But at the southern edge of the range, the waters may be getting too warm, putting the animals under extreme stress.

According to a 2013 study, marine species are pushing their range boundaries poleward, away from the Equator, at an average speed of 4.5 miles a year. That’s 10 times as fast as the speed at which species on land are moving.
