Response Statement - Deepwater Redfish, Gulf of St Response Statement - Deepwater Redfish, Gulf of St. Lawrence - Laurentian Channel population December 2, 2010 Common Name: Deepwater Redfish, Gulf of St. Lawrence - Laurentian Channel population Scientific Name: Sebastes mentella Status assessment by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC): Endangered How the Minister of the Environment intends to respond to the assessment: The Minister of Fisheries and Oceans will undertake consultations with the governments of Quebec, Newfoundland and Labrador, New Brunswick, Nova Scotia and Prince Edward Island, Aboriginal peoples, stakeholders, and the public on whether or not the Deepwater Redfish, Gulf of St. Lawrence - Laurentian Channel population, should be added to the List of Wildlife Species at Risk (Schedule 1) under the Species at Risk Act as Endangered. The Minister of the Environment will forward the COSEWIC assessment of the Deepwater Redfish, Gulf of St. Lawrence - Laurentian Channel population, to the Governor in Council upon completion of consultations. Once a species has been assessed by COSEWIC, further steps must be undertaken before it is added to Schedule 1 of the Species at Risk Act. For more information on this process, please view The Species Listing Process Under SARA. Reason(s) for status designation provided by COSEWIC: As with other members of the family Sebastidae, this species is long-lived (maximum age about 75 yr), late-maturing (generation time 18 yr), and highly vulnerable to mortality from human activities. Recruitment is episodic, with strong year-classes only occurring every 5-12 years. Abundance of mature individuals has declined 98% since 1984, somewhat more than one generation, and the decline has not ceased. Directed fishing and incidental harvest in fisheries for other species (bycatch) are the main known threats. Harvesting in parts of this population (Gulf of St. Lawrence) is currently limited to an index fishery, but commercial fisheries remain open in other areas (Laurentian Channel). Bycatch in shrimp fisheries has been substantially reduced since the 1990s by use of separator grates in trawls, but could still be frequent enough to affect recovery. Occurrence: Atlantic Ocean Competent Minister(s): Minister of Fisheries and Oceans Province(s) and territory (territories) to be consulted: Quebec Newfoundland and Labrador New Brunswick Nova Scotia Prince Edward Island Applicable federal legislation: Fisheries are managed and fish habitat is protected under the Fisheries Act. Conservation activities underway: Given their morphological similarities and the significant overlapping of their distribution areas, a number of criteria are needed to distinguish the deepwater redfish from the Acadian redfish. In view of the time and costs involved, it is hard to apply these criteria on a large scale. The "redfish" is therefore considered a single species within the fishing industry. The DFO recently recommended adopting a management strategy for each species (2008), and may soon begin drafting this. In the Northwest Atlantic, the redfish fishery is managed by DFO, NAFO, the U.S. government and certain American states. Since the Gulf of St. Lawrence and Laurentian Channel populations are exclusive to Canadian waters, they are managed by DFO. Further north, the stocks of the Grand Banks (NAFO divisions 3O and 3LN) are managed by NAFO, while those of Labrador (Sub-Zone 2) and northeast Newfoundland (Division 3K) are managed by DFO. The Acadian redfish population of the southern Scotian Shelf and Gulf of Maine is jointly managed by the United States and Canada. Moratoria on directed redfish fishing have been in force in the Gulf of St. Lawrence (Unit 1) since 1995, and in the southern Labrador (2J) and northeast Newfoundland (3K) divisions since 1988. The fishery in Grand Banks divisions 3L and 3N was reopened in 2010, after a moratorium that had been in place since 1998. Redfish fishing is subject to quotas on the Scotian Shelf, in the Gulf of Maine, and in Grand Banks Division 3O. In addition to catch limits, restrictions governing minimum catch and mesh sizes are in place to reduce pressure on immature redfish populations. To protect broodstock during spawning season, fishing in the Laurentian Channel is prohibited in May and June. A protected area has also been set aside for young redfish, to protect Acadian redfish populations in the southern sector (Browns Bank in the Gulf of Maine). The Nordmore grate, whose use in the northern shrimp fishery has been mandatory since 1994, considerably reduces redfish bycatches by allowing fish to escape from trawl nets..

Box 750 Sentrum, NO-0106 Oslo, Norway 2Department of Biology, University of Bergen, 5020 Bergen, Norway Author e-mails: [email protected] (HH), [email protected] (EK) *Corresponding author Received: 28 September 2017 / Accepted: 21 November 2017 / Published online: 1 December 2017 Handling editor: Henn Ojaveer Abstract During an angling competition in the Oslofjord, Southern Norway, a fish species previously unknown to the anglers was caught. Subsequent morphological studies and DNA barcoding identified it as a false kelpfish, Sebastiscus marmoratus (Cuvier, 1829), a species native to the Western Pacific from southern Hokkaido, Japan to the Philippines. The specimen was a female with a length of 29.2 cm and weighing 453 g. Stomach contents revealed fish remains, as well as the brachyuran Xantho pilipes A. Milne-Edwards, 1867 and remains of anomuran decapods. Parasitological examination revealed infections with the locally common generalist parasites Derogenes varicus (Digenea) and Hysterothylacium aduncum (Nematoda) that likely have been acquired through prey fish. A literature study of the parasites of S. marmoratus was carried out, listing at least 31 species. To the best of our knowledge, this is the first report of this fish species in the Atlantic. The introduction route is unknown, but the most likely possibility is via a ship’s ballast water as a larva or fry, which again would imply that the specimen has been in temperate waters for several years.

Address correspondence to W. L. Smith at the address above, or e-mail: [email protected]. Abstract Knowledge of evolutionary relationships or phylogeny allows for effective predictions about the unstudied characteristics of species. These include the presence and biological activity of an organism’s venoms. To date, most venom bioprospecting has focused on snakes, resulting in six stroke and cancer treatment drugs that are nearing U.S. Food and Drug Administration review. Fishes, however, with thousands of venoms, represent an untapped resource of natural products. The first step in- volved in the efficient bioprospecting of these compounds is a phylogeny of venomous fishes. Here, we show the results of such an analysis and provide the first explicit suborder-level phylogeny for spiny-rayed fishes. The results, based on ;1.1 million aligned base pairs, suggest that, in contrast to previous estimates of 200 venomous fishes, .1,200 fishes in 12 clades should be presumed venomous.

    Life history characteristics, management strategies, and environmental and economic factors that contribute to the vulnerability of rockfish stocks off Alaska Item Type Thesis Authors Patt, Jacqueline Download date 26/09/2021 06:08:55 Link to Item http://hdl.handle.net/11122/4812 LIFE HISTORY CHARACTERISTICS, MANAGEMENT STRATEGIES, AND ENVIRONMENTAL AND ECONOMIC FACTORS THAT CONTRIBUTE TO THE VULNERABILITY OF ROCKFISH STOCKS OFF ALASKA A THESIS Presented to the Faculty of the University of Alaska Fairbanks in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE By Jacqueline Patt, B.S. Fairbanks, Alaska December 2014 Abstract This study explored the extent to which variations in biological characteristics, environmental and economic factors, and management strategies have affected the tendency for rockfish to become overfished. The analysis used data on 5 species of rockfish that account for more than 95% of commercial catch of rockfish in the Gulf of Alaska (GOA) and Bering Sea and Aleutian Island (BSAI) management regions. These species are: Shortraker Rockfish ( Sebastes borealis ), Pacific Ocean Perch ( Sebastes alutus ), Northern Rockfish ( Sebastes polyspinis ), Dusky Rockfish ( Sebastes variabilis ), and Shortspine Thornyhead ( Sebastolobus alascanus ). Fishery management models often treat BMSY , the biomass level that maximizes sustainable yield, as a critical reference point; whenever the biomass of a federally managed fish or shellfish stock is estimated at less than 0.5× BMSY , the stock is declared “overfished” and managers are required to develop a recovery plan that will restore stock abundance above BMSY within about one generation length. Because estimates of BMSY are unavailable for some GOA and BSAI rockfish stocks included in this analysis and because we were interested in developing a model that could be applied to data-poor stocks, we explored two proxies for BMSY .

  • The First Two Complete Mitochondrial Genomes for the Family Triglidae
    www.nature.com/scientificreports OPEN The first two complete mitochondrial genomes for the family Triglidae and implications Received: 20 January 2017 Accepted: 31 March 2017 for the higher phylogeny of Published: xx xx xxxx Scorpaeniformes Lei Cui1, Yuelei Dong1, Fenghua Liu1, Xingchen Gao2, Hua Zhang1, Li Li1, Jingyi Cen1 & Songhui Lu1 The mitochondrial genome (mitogenome) can provide useful information for analyzing phylogeny and molecular evolution. Scorpaeniformes is one of the most diverse teleostean orders and has great commercial importance. To develop mitogenome data for this important group, we determined the complete mitogenomes of two gurnards Chelidonichthys kumu and Lepidotrigla microptera of Triglidae within Scorpaeniformes for the first time. The mitogenomes are 16,495 bp long in C. kumu and 16,610 bp long in L. microptera. Both the mitogenomes contain 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes and two non-coding regions. All PCGs are initiated by ATG codons, except for the cytochrome coxidase subunit 1 (cox1) gene. All of the tRNA genes could be folded into typical cloverleaf secondary structures, with the exception of tRNASer(AGN) lacks a dihydrouracil (DHU) stem. The control regions are both 838 bp and contain several features common to Scorpaeniformes. The phylogenetic relationships of 33 fish mitogenomes using Bayesian Inference (BI) and Maximum Likelihood (ML) based on nucleotide and amino acid sequences of 13 PCGs indicated that the mitogenome sequences could be useful in resolving higher-level relationship of Scorpaeniformes. The results may provide more insight into the mitogenome evolution of teleostean species. Generally, the fish mitogenome is a circular and double-stranded molecule ranging from 15 to 19 kilobases in length.
