Cuckoo Ray (Leucoraja Naevus) in Division 9.A (Atlantic Iberian Waters)
ICES Advice on fishing opportunities, catch, and effort Bay of Biscay and the Iberian Coast ecoregion Published 2 October 2020 Cuckoo ray (Leucoraja naevus) in Division 9.a (Atlantic Iberian waters) ICES advice on fishing opportunities ICES advises that when the precautionary approach is applied, catches should be no more than 120 tonnes in each of the years 2021 and 2022. If discard rates do not change from the average of the last five years (2015–2019), this implies landings of no more than 84 tonnes. Note: This advice sheet is abbreviated due to the COVID-19 disruption. The previous advice issued for 2019 and 2020 is attached as Annex 1. Stock development over time Figure 1 Cuckoo ray in Division 9.a. Left: ICES landings estimates (all fleets: 2002–2019) and discards (Spanish fleet: 2015– 2019). Right: The stock-size indicator (solid line) is the combined biomass survey index (normalized) from the two Spanish groundfish surveys in the Gulf of Cadiz (SpGFS-GC-WIBTS-Q1, SpGFS–GC-WIBTS-Q4).

State of the stock and the fishery relative to reference points. Catch scenarios The precautionary buffer was last applied in 2014. The status of the stock size and fishing pressure relative to reference points is unknown. However, because of a long-term increase in the stock-size indicator since 1998 and a significant decrease in the fishing effort over the last ten years, the precautionary buffer was not applied in 2020. -
A Ban on Bluefin Just Might
Published on The New Republic (http://www.tnr.com) Bradford Plumer March 4, 2010 | 1:50 pm For some time now, it's seemed likely that the Atlantic bluefin tuna would go extinct in the next few years. The popular sushi staple has been drastically overfished, its stocks have collapsed, and recent attempts to set global quotas on annual catches were half-hearted and inadequate. It's been a bleak scene all around. But now marine biologist Carl Safina brings word that there's one last attempt to save the tuna—a ban on international trade. And here's why it just might work: Because bluefin tuna fishing worldwide is driven by prices paid in Japan, where individual fish have sold wholesale for up to $175,000, every population is depleted. … Even if international trade is banned, bluefin tuna could still be caught and sold within any given country. But the fish are now sufficiently scarce that without Japan’s prices, many boats would turn unprofitable and give up. The fish could recover, and a more sustainable fishery develop. The United States has supported a ban, while Japan isn't too keen on the idea. Which means a lot will depend on whether the EU countries vote as a bloc and decide to support the ban. (They've been noncommittal so far.) It's sort of remarkable: A few decades ago, the idea that any of these countries could support a ban would have been unthinkable—there's just too much money at stake for the fishing industry, and the lobbying pressure can be intense. -

Note Crisis at Sea: Strengthening Government Regulation To Save Marine Fisheries Nicola Kieves * Around the world the health of marine fisheries continues to deteriorate.' In American waters, overfishing occurs in more than half of all fisheries. 2 Because they are an open-access re- source "owned by all and owned by none," 3 in the absence of some restrictions, fisheries are likely to be harvested until deci- mated. 4 Countries continue to close their most profitable fisher- ies,5 threatening society's health and economic welfare. 6 Socially, overfishing leads to longer working hours, lower wages, and increased rates of unemployment for fishermen. 7 * J.D.

Adult Chondrogenesis and Spontaneous Cartilage Repair in the Skate, Leucoraja Erinacea Aleksandra Marconi1, Amy Hancock-Ronemus2,3, J Andrew Gillis1,3*
RESEARCH ARTICLE Adult chondrogenesis and spontaneous cartilage repair in the skate, Leucoraja erinacea Aleksandra Marconi1, Amy Hancock-Ronemus2,3, J Andrew Gillis1,3* 1Department of Zoology, University of Cambridge, Cambridge, United Kingdom; 2Charles River Laboratories, Wilmington, Massachusetts, United States; 3Marine Biological Laboratory, Woods Hole, Massachusetts, United States Abstract Mammalian articular cartilage is an avascular tissue with poor capacity for spontaneous repair. Here, we show that embryonic development of cartilage in the skate (Leucoraja erinacea) mirrors that of mammals, with developing chondrocytes co-expressing genes encoding the transcription factors Sox5, Sox6 and Sox9. However, in skate, transcriptional features of developing cartilage persist into adulthood, both in peripheral chondrocytes and in cells of the fibrous perichondrium that ensheaths the skeleton. Using pulse-chase label retention experiments and multiplexed in situ hybridization, we identify a population of cycling Sox5/6/9+ perichondral progenitor cells that generate new cartilage during adult growth, and we show that persistence of chondrogenesis in adult skates correlates with ability to spontaneously repair cartilage injuries. Skates therefore offer a unique model for adult chondrogenesis and cartilage repair and may serve as inspiration for novel cell-based therapies for skeletal pathologies, such as osteoarthritis. Introduction Hyaline cartilage is a skeletal tissue that consists of a single cell type (the chondrocyte) embedded *For correspondence: [email protected] within a homogeneous, collagenous extracellular matrix (reviewed in Gillis, 2018). In mammals, hya- line cartilage is predominantly an embryonic tissue, making up the anlage of the axial (chondrocra- Competing interests: The nial, vertebral and rib) and appendicular (limb) endoskeleton. The vast majority of mammalian authors declare that no hyaline cartilage is replaced by bone during the process of endochondral ossification, with cartilage competing interests exist. -

A Voice for Nature
Agenda Item F.3.b Supplemental Public Comment 2 Full Version ELECTRONIC Only March 2016 February 25, 2016 Dorothy Lowman, Chair Pacific Fishery Management Council 1100 NE Ambassador Place, #101 Portland, Oregon 97220 RE Agenda Item G.2: Swordfish Management Policy Connections; authorization of deep set buoy gear Dear Chair Lowman and Council Members: We understand that the Council is now considering transitioning buoy gear from an experimental gear to a federally authorized gear under the Highly Migratory Species Fishery Management Plan. We are writing to ask the Council to make authorization of buoy gear a high priority and initiate this process early in 2016, so that West Coast fishermen can start fishing with buoy gear as soon as possible. As an organization that works to create a more knowledgeable constituency for ocean conservation and assesses the sustainability of seafood species, we are always thrilled to hear of innovative ideas that could improve the way we fish. This is why we are so excited about deep-set buoy gear. We believe that buoy gear is a viable alternative to the currently used drift gillnets in the U.S. West Coast swordfish fishery, and could help make the fishery more sustainable. Experiments conducted with buoy gear off the West Coast have found that this fishing method catches high numbers of marketable swordfish and minimal amounts of non-target species, like sea turtles, whales, and bluefin tuna. This fishing method also results in a higher quality swordfish product, similar to harpoon-caught swordfish; this means fishermen get a higher price for their catch and consumers get a tastier product. -
By PAUL GREENBERG Published: August 12, 2007 a Few Months
By PAUL GREENBERG Published: August 12, 2007 A few months ago I took the most expensive nap of my life, and when it was over I decided it was all Hemingway’s fault. For $500, I booked a marlin charter out of Kailua-Kona, Hawaii. I had never gone for the really big fish, and I was juiced to finally get the chance. I imagined myself sitting, like Papa, on the deck of the Pilar, fighting the big fish in the big chair, muttering through gritted teeth the great man’s motto “Il faut (d’abord) durer” — first, one must endure. But after hours of dragging footlong lures at 8 knots, I began thinking that it could be the big fish that have not endured. Not a single marlin raised its sword to our lines, nor did one appear for the other 30-odd boats trolling in the lee of the trade winds that day. And as I nodded off in the fighting chair and recalled the photographs of Hemingway posed with giant marlin and tuna, I started wondering whether it was possible to calculate the effect the world’s best fishing writer might have had on the world’s biggest fish. The thought wouldn’t have occurred to me a few years ago. Like Hemingway, I took up fishing because of the limitlessness the sea seemed to offer. I shared his notion that the “great ocean currents are the last wild country there is left,” and believed of the sea as Hemingway did that “no one knows what fish live in it, or how great size they reach.” As a child, if I ever felt guilty about my kills, I summoned a kind of waking dream in which all my victims thanked me.
