Le secteur marin au large de la péninsule de Manicouagan a été ciblé comme future zone de protection marine (ZPM) en vue de conserver et protéger cet espace marin productif et diversifié. Dans le cadre du programme Santé des Océans, la Direction régionale des sciences du ministère des Pêches et des Océans doit fournir aux gestionnaires des ZPM (Direction régionale des océans, de lhabitat et des espèces en péril) une recommandation de suivi écologique pour chacune des ZPM. Le développement dun suivi écologique comprend trois étapes : dresser le portrait de la zone, concevoir le suivi et, enfin, le réaliser. Le présent document traite des deux premières étapes en dressant le portrait de lécosystème de la ZPM Manicouagan à partir des connaissances disponibles et en ciblant les composantes écologiques à suivre pour évaluer latteinte des objectifs de conservation de la ZPM. Deux groupes de composantes ont été sélectionnés : 1) celui des composantes dites représentatives de la ZPM qui permettront dévaluer la performance de la ZPM dans latteinte des objectifs de conservation et 2) celui des composantes qui permettront un suivi de létat global de lécosystème de la ZPM et apporteront un support à linterprétation des indicateurs de performance.

The Manicouagan Marine Protected Area is about to be created under the Oceans Act. Following the designation of the MPA, monitoring must be undertaken to determine whether the areas conservation objectives are being met. The Manicouagan MPA objectives aim to maintain biological productivity and diversity and to ensure sustainable exploitation of the resources. The development of a monitoring plan was initiated by drafting an ecological monitoring framework, presenting the ecological information on the area and identifying the existing and potential monitoring programs, as well as the information that needs to be obtained. In order to complete and improve the monitoring framework, three workshops that focussed on 1) exploited resources, 2) productivity and oceanography, and 3) biological diversity in the region including and immediately surrounding the MPA were held at the Maurice Lamontagne Institute in the winter of 2006-07. Most of the participants are affiliated with the DFO Regional Science Branch. Workshop 1: Using the available information on the principal exploited biological resources in the MPA, the specialists proposed to monitor the whelk and softshell clam populations. Several indicators were recommended for these species. The current monitoring of snow crab should suffice to monitor its population status in the MPA. Workshop 2: Knowledge on the biological oceanography for the entire St. Lawrence Estuary, as presented by the experts, was used to express hypotheses about the water dynamics in the MPA. Freshwater flows from rivers, wind and cold water upwellings were identified as determining processes in the area. The vast foreshore, the underwater bay and the coastal slope are likely to be significant productivity sectors. It was assessed that phytoplankton (especially toxic algae), filter-feeding shellfish near the estuaries, eelgrass beds, salt marshes and juvenile fish noticeably contribute to the regions productivity. Experts recommend to monitor the organisms that are produced in the area, particularly sedentary organisms, constantly subjected to the MPA conditions. The environmental pressures affecting key components were considered and a need to know and monitor sediment contamination levels was identified. Workshop 3: Available information on the biological diversity in the MPA was presented. Eelgrass beds, salt marshes and mollusc-dominated communities seem important for the diversity of the coastal area. The groundfish diversity appears to be high in the MPA. For the entire MPA, several epibenthos assemblages were mapped. Data from deeper waters are limited, but experts estimate that endobenthos and suprabenthos are important groups. Snow crab, occurring almost throughout the MPA, can act as a structuring predator in benthic communities. The sectors geology and bank erosion were the topic of a presentation, as well as the possible use of biomarkers and genetics in monitoring. Overall, an ecosystemic monitoring focusing on the systems key components is accepted by the peers, but the distribution and intensity of the environmental pressures must also be taken into account in the overall approach. For future indicator species, species with direct development and of low mobility should be preferred.

Les zone de protection marines (ZPM) découlent de la Loi concernant les océans du Canada et font partie des programmes fédéraux de création d'aires marines protégées. Les ZPM se distinguent toutefois de ces autres programmes du fait qu'elles constituent des outils de gestion flexibles axés sur des besoins spécifiques. Elles visent la protection accrue des espèces et des habitats marins dans le respect des juridictions existantes. Pêches et Océans Canada (MPO) est l'organisme responsable du programme des ZPM. L'implication, la participation active et la concertation d'un grand nombre d'intervenants seront requises pour mener à bien ce programme. C'est dans ce contexte qu'un premier projet de ZPM a vu le jour au Québec et a été proposé à la population de la région de Manicouagan. Le présent rapport se veut une synthèse de la consultation publique, incluant les sessions tenues du 29 novembre au 6 décembre 2001, sur un projet de ZPM dans le secteur de la péninsule de Manicouagan. Ce rapport comprend : une mise en contexte du projet et de la consultation publique; un résumé des avis, interventions et préoccupations exprimés face au projet par la population, les organismes du milieu et les gestionnaires du territoire; une évaluation du niveau d'acceptation sociale du projet; une analyse des opportunités, des préoccupations et des propositions exprimées dans le cadre de la consultation; et, enfin, les recommandations du comité technique quant à la poursuite du projet.

The main Greenland halibut concentrations in the Gulf of St. Lawrence during the summer are found west of Anticosti Island and, to a lesser extent, north of this Island and in the Esquiman Channel, near the west coast of Newfoundland. Gillnets are the main gear type used in this fishery since the mid-1970s. The 1997 preliminary landings totalled 2 459 t. The total allowable catch (TAC) was set at 3 000 t in 1997. On the whole, the CPUEs of index fishermen were twice as high in 1996 and 1997 as during the period 1991 to 1995. Abundance indices for Greenland halibut have risen since 1990, with a more pronounced increase since 1994. The abundance of commercial-size individuals (over 40 cm) has increased since 1994 owing to the presence of strong year-classes. In 1996 and 1997, the number of juveniles rose significantly. In addition, the length at which 50 % of females reach maturity was estimated at 50 cm during this period. Preliminary results from microscopic analyses of ovaries have revealed evidence of maturation that cannot be seen with the naked eye. Parasite research has shown that the Greenland halibut concentrated in the Cabot Strait area in winter probably come from the Gulf of St. Lawrence.
ARTHUR, R., E. ALBERT, 1996. Parasites as potential biological tags for capelin (Mallotus villosus) in the St. Lawrence estuary and gulf. Can. Tech. Rep. Fish. Aquat. Sci., 2112, 9 p .
Parasitological data were analysed in an attempt ot separate collections of male capelin (Mallotus villosus) caught on the spawning grounds at five localities in the estuary of the St. Lawrence River and the Gulf of St. Lawrence, Canada, in 1994. Only three of the 21 parasite taxa infecting Gulf capelin were considered potentially useful as stock discriminators : the protistan Microsporidium sp. And the larval nematodes Anisakis simplex and Contracaecinea gen. Sp. The results of nonparametric discriminant analyses showed a very low percentage of correct classification, with only 24 ppt (30/125) of the fish being assigned to their true category. No pattern of misclassification was observed to support the regrouping of collections by eastern and western origin. Parasitological data thus provide no evidence to support the concept of separate stocks of capelin in the St. Lawrence estuary and gulf.

A survey of the parasites of Greenland halibut (Reinhardtius hippoglossoides) caught in Canadian Atlantic waters extending from Cumberland Sound, Northwest Territories, to the Gulf of St. Lawrence and Saguenay Fjord was conducted during the period January 1990 to March 1991. From examination of 350 fish a total of 46 parasite taxa were identified (4 Myxosporea, 1 Monogenea, 19 Digenea, 6 Cestoda, 8 Nematoda, 5 Acanthocephala, 2 Crustacea, and 1 Hirudinoidea). Included among these are 15 taxa previously unreported from this fish (Genolinea laticauda Manter, 1925; Gonocerca phycidis Manter 1925; Neophasis sp.; Podocotyle reflexa (Creplin, 1825); Prosorhynchus squamatus Odhner, 1905; Steringophorus sp.; Eubothrium parvum Nybelin, 1922; Proteocephalus sp.; Ascarophis arctica Polyansky, 1952; Ascarophis filiformis Polyansky, 1952; Spirurida gen. Sp. Larva; Corynosoma validum Van Cleave, 1953; Corynosoma wegeneri Heinze, 1934; Gnathia elongata (Krøyer, 1849); and Notostomum laeve Levinsen, 1882). New Canadian records include only Steringophorus sp. And N. laeve. The parasite fauna of Greenland halibut is characterized by a large number of ubiquitous species, including many larval forms that show little host specificity, and a smaller number of species typical of pleuronectiform fishes, two of which (Myxoproteus reinhardti (Wierzbicka, 1986) and Hatschekia reinhardtii Wierzbicka, 1989) are known only from this fish. A complete listing of all parasite reported from Greenland halibut is included as an appendix.©1994 National Research Council Canada

The usefulness of parasites as biological tags for stocks of Greenland halibut (Reinhardtius hippoglossoides) occurring off the Atlantic coast of Canada and in the Gulf of St. Lawrence was investigated. Nonparametric discriminant function analyses of eight collections comprising a total of 231 large fish (>39 cm) using counts for selected parasite taxa (Corynosoma strumosum juvenile, Otodistomum sp. Metacercaria, Contracaecinea spp. Larva, Anisakis simplex larva, and Pseudoterranova decipiens larva) gave accurate results (almost 100 % correct classification) for the separation of fish from the Gulf of St. Lawrence from those collected from adjacent areas of the Saguenay Fjord and the Atlantic Ocean off Labrador. Little, if any, mixing of subadult or adult fish apparently occurs among these areas.©1993 National Research Council of Canada
ARTHUR, J.R., E. ALBERT, 1992. The use of parasites for separating stocks of Greenland halibut (Reinhardtius hippoglossoides) in the Atlantic Ocean off Canada. CAFSAC Res. Doc., 92/93, 21 p .
A study was conducted to determine the usefulness of parasites as biological tags for stocks of Greenland halibut occurring off the Atlantic coast of Canada and in the Gulf of St. Lawrence. More than 40 species of parasites were identified from examination of a total of 231 large fish (greater than 39 cm) collected from eight localities. Analyses using five taxa (Corynosoma strumosum juvenile, Otodistomum sp. metacercaria, Contracaecinea spp. larva, Anisakis simplex larva and Pseudoterranova decipiens larva) gave highly accurate results (almost 100 ppt correct classification) for the separation of fish from the Gulf of St. Lawrence from those collected from adjacent areas of the Saguenay Fjord and the Atlantic Ocean off Labrador. It is concluded that little, if any mixing of subadult or adult fish occurs among these areas.
ALBERT, E., M.A. CURTIS, 1991. Prevalence and abundance of helminth parasites in an intensively fished population of brook trout (Salvelinus fontinalis) at a small subarctic lake. Can. J. Zool., 69: 691-697 .
Brook trout from a 5-ha lake near Schefferville, Québec, were intensively sampled by small-mesh gill nets during 2 successive years to study patterns of helminth parasite occurrence in relation to changes in the age and size class structure of the fish population. Nearly 1800 brook trout were removed from the lake, of which all were measured and weighed, 568 were aged by otolith readings, and 361 were examined for parasites. The digeneans Crepidostomum farionis, Phyllodistomum umblae, and Diplostomum sp. And the cestode Eubothrium salvelini were present in more than 50 % of the necropsied fish, and the prevalence and (or) abundance of all species except C. farionis increased from the first to the second year of the study. The fish catch in the first year was dominated by the 3+ year class and older fish, whereas by the second year 1+ and 2+ fish were proportionately more abundant, and the importance of older cohorts declined. This change in brook trout population structure, resulting from gill net selectivity, appears to have had the effect of improving per capita food availability for members of the residual stock. After the initial year of intensive fishing, the fish that remained fed more upon both benthic and planktonic invertebrates and their acquisition of parasites was intensified.©1991 National Research Council of Canada
