Saving Seafood

Baby fish will be lost at sea in acidified oceans

December 15, 2015 — The ability of baby fish to find a home, or other safe haven, to grow into adulthood will be severely impacted under predicted ocean acidification, University of Adelaide research has found. 

Published today in the journal Proceedings of the Royal Society B, the researchers report the interpretation of normal ocean sound cues which help baby fish find an appropriate home is completely confused under the levels of CO2 predicted to be found in oceans by the end of the century.

“Locating appropriate homes is a crucial step in the life cycle of fish,” says Tullio Rossi, PhD candidate with the University’s Environment Institute. “After hatching in the open ocean, baby fish travel to reefs or mangroves as safe havens to feed and grow into adults.

“Baby fish can find those places through ocean noise: snapping shrimps and other creatures produce sounds that the baby fish follow.

“But when ocean acidity increases due to increased CO2, the neurological pathways in their brain are affected and, instead of heading towards those sounds, they turn tail and swim away.”

Global Supermarkets Selling Shrimp Peeled by Slaves

December 13, 2015 — SAMUT SAKHON, Thailand (AP) — Every morning at 2 a.m., they heard a kick on the door and a threat: Get up or get beaten. For the next 16 hours, No. 31 and his wife stood in the factory that owned them with their aching hands in ice water. They ripped the guts, heads, tails and shells off shrimp bound for overseas markets, including grocery stores and all-you-can-eat buffets across the United States.

After being sold to the Gig Peeling Factory, they were at the mercy of their Thai bosses, trapped with nearly 100 other Burmese migrants. Children worked alongside them, including a girl so tiny she had to stand on a stool to reach the peeling table. Some had been there for months, even years, getting little or no pay. Always, someone was watching.

No names were ever used, only numbers given by their boss — Tin Nyo Win was No. 31.

Pervasive human trafficking has helped turn Thailand into one of the world’s biggest shrimp providers. Despite repeated promises by businesses and government to clean up the country’s $7 billion seafood export industry, an Associated Press investigation has found shrimp peeled by modern-day slaves is reaching the U.S., Europe and Asia.

The problem is fueled by corruption and complicity among police and authorities. Arrests and prosecutions are rare. Raids can end up sending migrants without proper paperwork to jail, while owners go unpunished.

More than 2,000 trapped fishermen have been freed this year as a result of an ongoing Associated Press investigative series into slavery in the Thai seafood industry. The reports also have led to a dozen arrests, millions of dollars’ worth of seizures and proposals for new federal laws.

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.”

Regulators to decide whether to keep Maine shrimp ban

December 7, 2015 — PORTSMOUTH, New Hampshire – Fishing regulators are ready to decide if a moratorium on fishing for Maine shrimp will be extended into next year.

Fishermen haven’t been able to catch the shrimp since 2013. The Atlantic States Marine Fisheries Commission’s Northern Shrimp Section is scheduled to meet on Monday in Portsmouth to decide if that will continue.

The commission’s Northern Shrimp Technical Committee says prospects for shrimp recovery are poor for the near future. It is asking the Northern Shrimp Section to extend the moratorium.

Panel says moratorium on Maine shrimp fishing should stay

November 24, 2015 — PORTLAND, Maine (AP) — A key panel says Maine shrimp are still depleted and fishing regulators’ moratorium on fishing for them should remain in effect in 2016.

Fishermen haven’t been able to catch the shrimp since 2013. They were previously sought by commercial fishermen from Maine, New Hampshire and Massachusetts and were a popular winter item at fish markets.

The interstate Atlantic States Marine Fisheries Commission’s Northern Shrimp Technical Committee says prospects for shrimp recovery is poor for the near future. The committee is asking the Northern Shrimp Section to extend the moratorium at a Dec. 7 meeting in Portsmouth, New Hampshire.

Fate of New England shrimp fishery will be decided soon

November 23, 2015 — ELLSWORTH — Fishermen wondering whether there will be a shrimp season this winter won’t have long to wait for an answer.

On Monday, Dec. 7, the Atlantic States Marine Fisheries Commission’s Northern Shrimp Section and Advisory Panel will meet in Portsmouth, N.H., to decide whether boats from Maine, New Hampshire and Massachusetts will be allowed to this winter. Last year, the regulators imposed a moratorium on fishing because scientists said the shrimp stock was on the verge of collapse.

Next month, the scientific advisory panel will meet to review the 2015 Stock Status Report and develop recommendations for the 2016 fishing season. The section will meet later in the day to set specifications for the 2016 fishing season, if there is to be one, after reviewing the 2015 Stock Status Report and the advisory panel recommendations.

Information from the ASMFC suggests that another moratorium is likely. According to surveys in the Gulf of Maine, between 2012 and 2014 the abundance of shrimp and the size of the shrimp biomass were at their lowest levels in the 31-year history of the survey. The 2014 fishable biomass was the lowest on record.”

The presence of juvenile shrimp in the survey was discouraging as well. Shrimp hatched during 2013 were not expected to reach fishable size until 2017 and the level of recruitment in 2014 was the ninth lowest since the surveys began.

In a document prepared to introduce the public to proposed changes to the Northern Shrimp Fishery Plan (which have been postponed), the ASMFC said that scientists believed that “the northern shrimp stock has collapsed with little prospect of recovery in the near future.

Warming Waters Have Been Biggest Detriment to Gulf of Maine Shrimp Stocks

November 17, 2015 — Soon, a decision will be formed as to whether or not to open the Gulf of Maine’s shrimp fishery.

The decision to open or keep closed the fishery will soon be unveiled, as a technical committee will meet this week to make its decision on the stock.

Margaret Hunter, marine resources scientist at the Department of Marine Resources in Boothbay Harbor, said the long process of whether or not to open the fishery is nearing a decision.

The northern shrimp fishery, which includes the Gulf of Maine, is managed by the Atlantic States Marine Fisheries Commission (ASMFC). Decisions for the Gulf of Maine shrimp fishery are made ASMFC’s Northern Shrimp Section, which is comprised of commissioners from Maine, New Hampshire and Massachusetts.

Hunter currently sits on the Northern Shrimp Technical Committee along with scientists from New Hampshire, Massachusetts and Maine.

Each fall, the TC presents an annual assessment and from that, makes recommendations for the upcoming season. Hunter said in an email that the TC is currently compiling its 2015 report and that the TC will have a webinar Thursday, Nov. 19 to craft its recommendation for the upcoming season.

“I cannot tell you what our recommendation will be yet; in 2013 and 2014 we recommended no fishery,” she said in an email. “We hope to have our document finalized and out to the public around Nov. 25.”

Decision on 2016 Maine shrimp season due Dec. 7, outlook bleak

November 13, 2015 — Interstate fishing regulators say they will meet next month to decide if there will be a fishing season for Gulf of Maine shrimp next year, though they say prospects are bleak.

The fishery is currently shut down over concerns about its low population. Fishermen haven’t been able to catch the popular food species since 2013. A panel of the Atlantic States Marine Fisheries Commission will make a decision about the coming season on Dec. 7 in Portsmouth, N.H.

The fishery was formerly a popular winter fishery for fishermen who spent the warmer months trapping lobsters.

After mass extinctions, the meek (fish) inherit the earth

November 16, 2015 — A new study suggests that being a little shrimpy might come in handy when the going gets tough. A mass extinction called the Hangenberg event, which took place some 359 million years ago, led to a reduction in vertebrate size for around 40 million years afterward. The research, published Thursday in Science, adds support to the so-called Lilliput Effect, which suggests that mass extinctions cause marked shrinkage in the animal population.

To study how fish fared after this devastating extinction, the University of Pennsylvania’s Lauren Sallen (along with Andrew K. Galimberti, now a graduate student at the University of Maine) studied 1,120 fish fossils dating back 419 to 323 million years ago. She found that the ancient fish had been increasing in size over time — which is to be expected — but that body size plummeted after 97 percent of species were wiped out.
