Seventh Meeting of the Canadian Eel Science Working Group : 14-16 October 2009, Moncton, New Brunswick by Groupe canadien de travail scientifique sur l'anguille( )

6 editions published in 2011 in English and French and held by 115 WorldCat member libraries worldwide

"The Canadian Eel Science Working Group (CESWoG) met for the seventh time from October 14-16, 2009 at the Future Inns in Moncton, New Brunswick. The purpose of the meeting was to: 1. plan a strategy for addressing a formal request for advice from the Department of Fisheries and Oceans (DFO) on the following questions: a. How do you assess cumulative impact of multiple dams in a watershed? b. What is best methodology for setting recruitment and escapement targets for a watershed, taking into account cumulative impacts? c. What is the current status of eels in Canada? d. What progress has been made toward meeting the goal of a 50% reduction in mortality, in both weight and numbers, relative to the baseline of average mortality in 1997-2002? 2. provide a forum for the presentation and discussion of new and emerging eel science in Canada. Since there was no formal request for advice by DFO, no advice is provided in this document."--Document
Assessment of Atlantic halibut on the Scotian Shelf and southern Grand Banks (NAFO divisions 3NOPs4VWX5Zc) by Shelley L Armsworthy( Book )

11 editions published between 2009 and 2011 in English and held by 107 WorldCat member libraries worldwide

Atlantic halibut (Hippoglossus hippoglossus) is the largest of the flatfishes and ranges widely in the waters off Canada's East Coast. The management unit (3NOPs4VWX5Zc) is based largely on tagging results that indicated Atlantic halibut move extensively throughout the Canadian North Atlantic. Information on Atlantic halibut has been gathered by Fisheries and Oceans Canada (DFO) summer research vessel (RV) trawl surveys since 1970. The 2010 assessment used a new framework and produced estimates of spawning stock biomass and fishing mortality. The tagging estimates of fishing mortality were compared to those of the assessment model. The assessment was requested to determine halibut removals (including surveys and bycatch of Atlantic halibut), the recent catch rate in the RV and halibut survey, stock status, and fishing mortality, as well as to identify candidate reference points to evaluate the consequences of different harvest levels.--Document
Scallop fishing area 29 : stock status and update for 2008 = Zone de pêche 29 du pétoncle : état du stock et mise à jour pour 2008( Book )

Scallop fishing area (SFA) 29 encompasses a very large inshore area inside the 12-mile territorial sea, from the south of Yarmouth to Cape North in Cape Breton. This report refers to only that portion of SFA 29 west of longitude 65°30ʹW continuing north to Scallop Production Area 3 at latitude 43°40ʹN. This report summarizes commercial fishery, research survey and observer data for the 2007 fishery and provides advice for the 2008 fishery.--Document
Potential impacts of fishing gears (excluding mobile bottom-contacting gears) on marine habitats and communities by Jake Rice( )

4 editions published in 2010 in English and held by 102 WorldCat member libraries worldwide

Canada is moving towards an ecosystem approach to the management of human activities in the sea. A Canadian Science Advisory Secretariat (CSAS) science advisory process was held in March 2006 to examine the impacts of trawl gears and scallop dredges on benthic habitats, populations, and communities. In January 2010, an additional science advisory process to examine the impacts of fishing gears not reviewed at the previous meeting in 2006 (i.e. mobile bottom-contacting trawls and dredges), to assemble available information on their uses, and to provide scientifically-based conclusions and advice regarding their potential impact on marine habitats and biodiversity. This science advisory report is based on the global and Canadian experience with various fishing gears (excluding bottom trawls and dredges). It presents a generic framework for the evaluation of individual fisheries
National science advisory meeting on section 73 permits under the Species at Risk Act : March 8-10, 2004, Moncton, New Brunswick by Réunion de consultation scientifique nationale sur la délivrance de permis en vertu de l'article 73 de la Loi sur les espèces en péril( )

In March 2004, Dept. of Fisheries and Oceans (DFO) Science and Fisheries Management Sectors convened in Moncton, New Brunswick to explore the requirements of science advice under Sections 73 & 74 of the Species at Risk Act (SARA), which was proclaimed in June 2003. SARA Sections 73 and 74 allow for the issuance of a permit or agreement authorizing a person to contravene the prohibitions in SARA against killing, harming, harassing, capturing, or taking a species legally listed as extirpated, endangered, or threatened. This can be done so long as certain conditions are first met. This meeting articulated the science advice that would be needed to determine whether the necessary conditions have been met prior to the issuance of a permit or agreement. Through case studies and discussions, the meeting was able to produce a framework for science advice, as well as technical guidelines. The proceedings presented in this document summarise the main discussion points, recommendations, and conclusions of the meeting.--Document
Assessment of Newfoundland and Labrador snow crab by Earle G Dawe( Book )

11 editions published between 2009 and 2015 in English and held by 99 WorldCat member libraries worldwide

This document presents research survey data and fishery data toward evaluating the status of the Newfoundland and Labrador snow crab resources. Stock status is assessed annually for inshore and offshore areas (where applicable) within each NAFO Division. Resource status is evaluated based on trends in fishery catch per unit of effort (CPUE), exploitable biomass indices, recruitment prospects, and mortality indices. Data are derived from multi-species bottom trawl surveys in Div. 2HJ3KLNOP, Dept. of Fisheries and Oceans (DFO) inshore trap surveys in Div. 3KL, fishery data from logbooks, observer catch-effort data, industry-DFO collaborative trap survey data, as well as biological sampling data from multiple sources.--Document
Abundance of resident Atlantic cod in Gilbert Bay, Labrador, based on mark recapture, sampling catch per unit effort and commercial tag return data collected from 1998 to 2002 by C. J Morris( )

7 editions published in 2003 in English and held by 97 WorldCat member libraries worldwide

La baie Gilbert est située le long de la côte sud du Labrador près des localités de Williams Harbour et de Port Hope Simpson. Elle a été désignée zone d'intérêt (ZI) dans le cadre du Programme de zones de protection marines (ZPM) par le ministère des Pêches et des Océans (MPO) le 12 octobre 2000. On a utilise des données de marquage-recapture dans un bras de la baie Gilbert, des données sur les prises par unité d'effort provenant de l'échantillonnage scientifique et les données sur les retours d'étiquettes dans la pêche commerciale pour estimer l'effectif de la population de morue résidente. Cette estimation est fondée principalement sur les morues de l'Atlantique étiquetées et reprises ultérieurement lors d'un échantillonnage scientifique. Les prises par unité d'effort en plusieurs endroits de la baie révèlent que la morue n'est pas uniformément repartie durant la période de fraye printanière. D'après les étiquettes renvoyées par les pêcheurs commerciaux, les plus grands poissons de la population sont captures de manière disproportionnée par ces pêcheurs. Les données de marquage-recapture révèlent que la biomasse de la population de morue de la baie Gilbert est inférieure à 70 tonnes. La mortalité par pêche commerciale en 1998 et 1999 a été estimée a 18 t et 16 t, respectivement, tandis que la mortalité par pêche récréative en 1998 a été estimée a 1,000 kg. Si la biomasse est d'environ 70 t, la population ne peut soutenir une pêche commerciale aux niveaux de 1998 et 1999. De plus amples recherches sont nécessaires pour évaluer les hypothèses sur lesquelles sont fondées notre estimation. Les décisions de gestion au sujet de ce stock devraient être prises séparément de celles qui concernent la morue du Nord et refléter l'effectif bas et incertain de la population
Assessment of Georges Bank scallops (Placopecten magellanicus) by Canada( Book )

16 editions published between 2006 and 2013 in English and held by 96 WorldCat member libraries worldwide

The sea scallop, Placopecten magellanicus, is found only in the Northwest Atlantic. Major areas of offshore fishing activity are Georges Bank, the Eastern Scotian Shelf (Middle Grounds, Sable Island Bank, and Western Bank), Browns Bank, German Bank, and St. Pierre Bank (south of Newfoundland). Annual assessments of the status of the offshore scallop resource take into account the annual survey findings, meat size distribution in the catch and fishery performance. The management of the main scallop fishery in Georges Bank refers to zone "a" and is the focus of this document
Exploitation rates and movements of Atlantic cod (Gadus morhua) in NAFO Divs. 3KL based on tagging experiments conducted during 1997-2002 by J Brattey( )

7 editions published in 2003 in English and held by 96 WorldCat member libraries worldwide

A large-scale mark-recapture study of adult (>45 cm) Atlantic cod (Gadus morhua), initiated in spring 1997, was continued. During 1997-2002 a total of 26,401 live cod were tagged with single, double, or high-reward t-bar anchor tags and released at various inshore locations off the east coast of Newfoundland. Approximately 3,870 tagged cod have been reported as recaptured up to 8 February 2003. Tag returns were adjusted to account for region-specific reporting rates, and the number of tagged cod available for capture was adjusted to account for tagging mortality, tag loss and assumed natural mortality. These data were used to estimate annual exploitation rates for each batch of tagged cod. To indicate where exploitation was taking place, the spatial distribution of recaptures from tagging in each area was summarized annually, with numbers recaptured adjusted to account for annual region-specific reporting rates. Estimates of exploitation for cod tagged in 3K in 1999 were high (29-63%) for 1999, but dropped dramatically (3.9-8.8%) during 2000 and 2001. Landings in 3K dropped from about 3,500 t in 1999 to only 600 t in 2002. Among cod tagged in Bonavista Bay (3La), estimates of exploitation were also highest for 1999, ranging from 6.0 to 18.4% with most estimates around 15%. Estimates for subsequent years were lower, except among more recently tagged cod released in 3La during 2001 and 2002 (4.5 24.5%). Estimates of exploitation for cod tagged in Trinity Bay (3Lb) during 1999 tended to be lower (3.5-13.2%) than those for Bonavista Bay. For 2000 and 2001 most estimates for cod tagged in 3Lb were between 5 and 15%. There was a marked increase in the estimates for 3Lb during 2002, particularly among cod tagged in Smith Sound where 5 of 12 estimates exceeded 20% giving cause for concern; most of the exploitation of these cod occurs outside Smith Sound as these fish disperse northward along the inshore during summer. The exploitation estimates for Conception Bay (3Lf) and the eastern Avalon (3Lj) tended to be low (<10%) and annual reported landings in these regions were low (300 600 t) throughout 1998-2002. In contrast, cod tagged in St. Marys Bay (3Lq) were more heavily exploited throughout 1998-2002 with 19 of 25 annual estimates exceeding 15%. Most of the exploitation of cod tagged in southern 3L occurs in Placentia Bay (3Psc), suggesting that many of the fish in this area are migrants from the neighbouring stock area. Cod in the inshore of northern 3L and 3K appear to comprise a separate stock component and do not appear to mix to any great extent with cod from southern 3L or 3Ps
Gaspereau River alewife stock status report = Rapport sur l'état du stock de gaspareau de la rivière Gaspereau by A. J. F Gibson( )

13 editions published between 2001 and 2007 in English and Undetermined and held by 94 WorldCat member libraries worldwide

The anadromous alewife (Alosa pseudoharengus) population of the Black River-Gaspereau River system in Nova Scotia supports both recreational and commercial fisheries of local importance. This assessment updates the status of the Black River-Gaspereau River alewife stock to the end of the 2006 fishing season. Estimates of annual abundance, escapement and exploitation rate as well as the biological traits of the runs in each year are presented. The methods used to estimate escapement since 2002 are presented for review. Biological characteristics of the annual spawning runs are presented to lend interpretation to the fisheries exploitation and spawner escapement information.--Document
Recovery potential modelling of eastern sand darter (Ammocrypta pellucida) in Canada = Modélisation du potentiel de rétablissement du dart de sable (Ammocrypta pellucida) au Canada by Mary Finch( )

5 editions published in 2011 in English and French and held by 92 WorldCat member libraries worldwide

In 2002, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed the eastern sand darter (Ammocrypta pellucida) as Threatened in Canada. In this study, the authors assess allowable harm, determine a population-based recovery target, conduct long-term projections of population recovery, and quantify habitat requirements in support of a recovery potential assessment (RPA) for the eastern sand darter.--Document
Indicateurs de l'état des stocks et points de référence conformes à une approche de précaution pour la crevette nordique du golfe du Saint-Laurent Stock status indicators and reference points consistent with a precautionary approach for northern shrimp in the Gulf of St. Lawrence by L Savard( )

3 editions published in 2012 in French and English and held by 91 WorldCat member libraries worldwide

Ce document présente l'indicateur utilisé pour évaluer l'état de la ressource depuis la saison de pêche 2009. L'indicateur principal de l'état des stocks est basé sur l'abondance des mâles et des femelles estimée à partir de la pêche commerciale et du relevé de recherche. De nouveaux points de référence basés sur cet indicateur sont proposés pour délimiter les zones de classification de l'état des stocks. Ces points de référence seront utilisés pour développer une approche de précaution à la gestion des stocks de crevette du golfe.--Document
Distribution de l'effort de pêche à la crevette nordique dans l'estuaire et le golfe du Saint-Laurent Distribution of northern shrimp fishing effort in the Estuary and Gulf of S. Lawrence by L Savard( )

4 editions published in 2012 in French and English and held by 91 WorldCat member libraries worldwide

Dans le golfe du Saint-Laurent, le seul type de pêche à la crevette nordique autorisé est une pêche commerciale pratiquée à l'aide d'un chalut de fond dont la grandeur minimale des mailles est de 40mm. Ce rapport décrit les activités de chalutage à la crevette dans l'estuaire et le golfe du Saint-Laurent entre 1982 et 2011. L'examen des activités de pêche permettra de catégoriser les secteurs exploités en fonction de l'intensité du chalutage. Les résultats de cet examen pourront servir à évaluer le risque que les activités de pêche causent des dommages à l'habitat et aux communautés benthiques.--Document

Évaluation des impacts potentiels de la pêche au chalut à la crevette nordique (Pandalus borealis) sur les habitats benthiques de l'estuaire et du nord du golfe du Saint-Laurent Assessment of the potential impacts of northern shrimp (Pandalus borealis) trawl fishing on benthic habitats in the Estuary and northern Gulf of St. Lawrence( )

3 editions published in 2012 in French and English and held by 91 WorldCat member libraries worldwide

Ce document présente les informations qui peuvent être utilisées pour déterminer les endroits où une activité de pêche soutenue au chalut à la crevette nordique pourrait avoir un impact majeur sur les habitats benthiques en général et sur les écosystèmes marins vulnérables en particulier. La crevette nordique est retrouvée principalement dans les chenaux à des profondeurs variant de 200 à 300 m où les sédiments sont fins et consolidés et où les perturbations naturelles ont peu d'impact sur l'habitat et les organismes biologiques. La majorité des sites de pêche qui ont subi un chalutage régulier et intensif sont situés entre 200 et 300 m de profondeur, dans les chenaux Esquiman et Anticosti et le long des deux versants du chenal Laurentien, à partir de l'extrémité est de l'île d'Anticosti jusque dans l'estuaire.--Document

A brief review of biological characteristics and assessment of the commercial Gaspereau fishery on the Lower Saint John River, N.B. by B. M Jessop( )

9 editions published in 2001 in English and held by 91 WorldCat member libraries worldwide

La pêche fixe dans la basse rivière Saint-Jean capture habituellement de 70 à 90 % des gaspareaux pêchés en aval du barrage Mactaquac. Depuis plus de 20 ans, les captures de gaspareaux dans la basse Saint-Jean sont inférieures à la moyenne à long terme. Les données biologiques recueillies périodiquement depuis 1973 indiquent que, dans les divers secteurs de pêche (sous-stocks géographiques), la forte pression de pêche a réduit la proportion des poissons âgés de plus de huit ans ainsi que la proportion de géniteurs ayant déjà frayé. Il faut réduire les taux d?exploitation pour obtenir des hausses significatives des prises futures
The scallop fishery in Newfoundland and Labrador becomes beleaguered by K. S Naidu( )

9 editions published in 2001 in English and held by 90 WorldCat member libraries worldwide

La pêche des pétoncles en 2000 en était à sa dernière année l'année précédente. Le nombre de pétoncliers actifs a diminué légèrement (72 contre 79 en 1999). En date de 1999, la réorientation est traduite par des captures généralement inférieures aux limites de captures anticipées. Les captures nominales ne correspondent désormais qu'ensemble, en excluant le Labrador, seulement 23 % du TAC disponible (2 647 t sur 11 430) ont été capturés
