Mischievous Snailfish and Other Mysteries of the Deep

June 15, 2016 — The following was released by NOAA:

Right now, scientists from the Alaska Fisheries Science Center are at sea collecting information crucial to keeping Alaska fisheries sustainable. The data they collect during yearly stock assessment surveys is used to set quotas for the familiar species that support some of world’s largest fisheries.

But sometimes they find something no one has seen before.

Mischievous, hardheaded, arbiter, dusty, peach, tomato, whiskered, combed, goldeneye, comet and comic snailfishes: none of these species were known to science 10 years ago. Some were named only last year. All were discovered by Alaska Fisheries Science Center biologist Jay Orr during stock assessment surveys in the Aleutian Islands.

Orr has discovered new skate, sculpin, sole and other species, but his favorites are the snailfishes. Alone or with coauthors including Morgan Busby (AFSC) and Katherine Maslenikov (University of Washington) he has discovered and named 12 new species of snailfishes. “My interest was sparked in 1997 when I collected one specimen that represented a new genus, and several that I thought were a known species out of their range”, Orr says. “When I examined one of these closely, I found it was a brand new species. And so was the second, and the third, and finally, a fourth newly discovered species. That’s what started me down this road.”

Some 350 snailfish species inhabit marine environments from the Arctic to Antarctic, from tide pools to deep sea – deeper than any other known vertebrate: one snailfish species was recently found swimming nearly 5 miles below the ocean surface. More than 50 species have been identified in the North Pacific; many more exist that are undescribed, and more continue to be discovered. In fact, Orr has collected twelve more unknown species that are now just waiting to be described.

A Slippery Fish

A snailfish looks a bit like an overweight tadpole. Naked of scales, its body seems gelatinous. Most species have a sucking disc in place of pelvic fins, and use it to attach themselves to rocks or other undersea surfaces. Most snailfish stay close to the bottom, rather than swimming in the water column.

Some of these characteristics partly explain why there are still so many unnamed snailfish. “They are challenging for taxonomists,” Orr says. “Because they don’t have scales, they get damaged easily. In the past, biologists might just call all snailfish ‘snailfish,’ instead of attempting to identify them.”

Taking advantage of a small bag added to the footrope of the trawl used to collect samples of other fish and invertebrates for species assessment, Orr’s group was able to collect undamaged snailfish, a true rarity. “The first time it was deployed it came up full of snailfish in perfect condition,” says Orr. “We aren’t sure why it works, but suspect it creates a vortex that gently sweeps up snailfish.”

Location, Location

Orr collects snailfish during fish and invertebrate species assessment cruises in the Aleutian Islands, as well as other regions in Alaska. Many of the new species were found in the Central Aleutians, and had not been identified during routine surveys of the entire Aleutian chain since 1980s.

The central Aleutians are a “biological hot spot” because of high productivity and prey availability. Snailfish may be concentrated in this high biodiversity area because of these favorable conditions. Also, they live and lay their eggs on the bottom, which may tend to keep them in this desirable real estate.

What’s in a Name?

“I name some of them according to what strikes me about the fish, its color or morphology,” says Orr. “I’ve also used descriptive words from the Aleut language, in honor of the Aleut people. And some species are named after individual people.”

Prognatholiparis ptychomandibularis, for example, means “protruding jaw snailfish, folded jaw,” and is commonly known as the wrinkle-jaw snailfish.

The goldeneye snailfish Allocareproctus unangas was named in honor of the Unangas, the Aleut people of Atka Island, near which the species was discovered.

The species name for Careproctus lerikimae, the dusty snailfish, is an amalgam of the first names–Libby, Erika, and Kim–of three scientists who helped collect the first specimens.

One hardheaded snailfish (Lopholiparis flerxi) was affectionately named after a colleague known for his keen eye for unusual specimens – and for his strong opinions.

Two most recently discovered species were named after retired leaders at the Alaska Fisheries Science Center who supported work in fisheries ecosystem management and biodiversity. “And they are just great guys,” says Orr. Orr has not named any species after himself (that’s just not done), but other scientists did: a whole new genus of fossil fishes is named Orrichthys, in honor of Orr’s contributions to the field.

NOAA Fisheries Announces Proposed Rules for Northeast Skate Fishery

June 6, 2016 — The following was released by NOAA Fisheries Greater Atlantic Region:

Today, NOAA Fisheries proposes, and opens for public comments, new management measures for the northeast skate fishery.

These were developed through Framework Adjustment 3 to the Northeast Skate Complex Fishery Management Plan at the recommendation of the New England Fishery Management Council.

The proposed measures are:

  • New quotas for the skate wing (8,372 mt) and bait (4,218 mt) fisheries for the 2016 and 2017.
  • All skate trip limits are proposed to remain unchanged from current levels.
  • Splitting the skate wing fishery quota into two seasons (May through August and September through April) to allow the directed fishery to be temporarily closed in-season if the seasonal quota is reached.

Read the proposed rule as filed in the Federal Register.

The comment period is open until 5pm on June 21.

Please submit your comments online or by mailing them to:

U.S. fisheries continue to rebuild; number of overfished stocks remains near all-time low

April 22, 2016 — The following was released by NOAA:

Total number of rebuilt U.S. marine fish stocks since 2000 rises to 39

The number of domestic fish stocks listed as overfished or subject to overfishing remain near all-time lows, according to the 2015 Status of U.S. Fisheries report to Congress.

The 2015 report highlights the United States’ continued progress towards managing fish stocks sustainably. This is a result of the combined efforts of NOAA Fisheries, commercial and recreational fishermen, the regional fishery management councils, states, and other partners.

“It’s fitting that this report aligns with the 40th anniversary of the Magnuson-Stevens Act,” said Eileen Sobeck, assistant NOAA administrator for fisheries. “Magnuson-Stevens provided the dynamic, science-based management process that is proving successful year after year at keeping U.S. fisheries among the world’s most sustainable and resilient. This year’s report highlights the act’s continued success.”

In 2015, eight stocks came off the overfishing list:

  • greater amberjack in the Gulf of Mexico
  • gray triggerfish in the Gulf of Mexico;
  • hogfish in the Eastern Gulf of Mexico;
  • thorny skate in the Gulf of Maine;
  • winter skate in Georges Bank/Southern New England;
  • windowpane flounder in the Gulf of Maine/Georges Bank;
  • Puerto Rico scups and porgies complex (similar species that occur in the same area)
  • Puerto Rico wrasses complex.

In addition, two stocks are no longer listed as overfished—blueline tilefish in the South Atlantic and canary rockfish along the Pacific Coast.

A stock is on the overfishing list when the annual catch rate is too high. A stock is on the overfished listwhen the population size of a stock is too low, whether because of fishing or other causes, such as environmental changes.

The report also found that two fish stocks—canary rockfish and petrale sole, both on the Pacific Coast—were rebuilt to target levels in 2015. That brings the total number of rebuilt U.S. marine fish stocks to 39 since 2000.

“This rebuilding success demonstrates the importance of the scientific monitoring and responsive management approach Congress built in to the Magnuson-Stevens Act,” said Sobeck. “It also shows that managing fisheries to sustainable levels in an ever-changing environment is an ongoing process of science informing management.”

New England Aquarium scientists studying imperiled skate

April 8, 2016 — PORTLAND, Maine — Scientists with Boston’s New England Aquarium are working on research projects to better inform the management of an imperiled species of skate.

Federal surveys indicate the thorny skate’s population has declined dramatically since the late 1960s.

From necessity, delicious seafood invention

April 5, 2016 — Because restaurants sell 70 percent of the seafood consumed in the United States, chefs are hugely influential in creating market trends, so Latitude 43’s chef Ryder Ritchie wants you to know there’s nothing fishy about dogfish. Or, for that matter, monkfish. Or pogies, or skate, or pollock, hake, tusk, or even, once you get the hang of them, those ubiquitous little invasive crustaceans, green crabs.

Notice, he doesn’t mention redfish, a species that — armed with their moveable feast of redfish soup — the formidable duo of Mayor Sefatia Romeo Theken and Angela DeFillipo have done a dazzling job of marketing at Boston’s Seafood Expo and beyond.

But everything else that might ever have been referred to as “trash fish?”

Look for it on chef Richie’s future forward menus at Latitude 43.

This Wednesday evening — Latitude 43’s third annual sustainable seafood benefit for Maritime Gloucester — Ritchie recommends for starters, Saffron Monkfish Stew in wild mushrooms and basil; Atlantic Razor Clams with lemongrass, house-made chilies and charred bread; followed by an entree of brown-butter-seared local flounder with capers and golden raisins, grilled asparagus, olive-oil-poached fingerling potatoes, sherry foam and pine nuts.

Flounder? Underutilized?

Yes, says Ritchie. Maybe not as underutilized as other species Gloucester natives like himself grew up hearing “bad stuff about,” but certainly never up there with, say, the now highly regulated, venerable cod.

Cape Cod fishermen anticipated cod collapse

March 25, 2016 — Dogfish Neck? Cape Skate? Pollock Peninsula?

Can this still be Cape Cod without the cod? There still is cod, and they’re still being caught, but the stocks have collapsed and that was further underlined this week when a Georges Bank quota cut of 62 percent to 762 metric tons was proposed by the National Oceanic and Atmospheric Administration’s Fisheries Management Council on Monday. That follows an earlier massive cut during the last three-year management period – totaling a 95-percent reduction over the last four years.

Outer Cape fishermen are ahead of the curve – most have already abandoned cod.

“We experienced the lack of cod first. It’s been a long time so several years ago our fishermen transferred to other fish. A lot fish for monkfish, skate, dogfish so the cod rules don’t impact them” explained Claire Fitz-Gerald, Policy Analyst for the Chatham based Cape Cod Commercial Fishermen’s Alliance.

As recently as 2003 Chatham fishermen brought in 1,053,290 pounds of cod to Chatham Fish Pier while the dogfish catch was 224,589 pounds in 2004 (there was no record for 2003). Now those numbers are flipped. In 2012 just 113,406 pounds of cod were landed at Chatham’s Pier, while 936,563 pounds of dogfish, 64,191 pounds of pollock, 287,753 pounds of skate were brought in.
