Le R\u00e9seau des observateurs du capelan (ROC) a \u00e9t\u00e9 mis en place dans le but de mieux conna\u00eetre les plages et les autres sites de fraie de l\u2019estuaire et du golfe du Saint-Laurent afin de favoriser la reproduction de l\u2019esp\u00e8ce.<\/p>\n

Combien y a-t-il de sites de fraie? Lesquels sont utilis\u00e9s chaque ann\u00e9e ou seulement occasionnellement? Y a-t-il des changements dans les habitudes de fraie du capelan? Qu\u2019est-ce qui influence l\u2019utilisation d\u2019une plage plut\u00f4t qu\u2019une autre? Le ROC contribue \u00e0 r\u00e9pondre directement \u00e0 ces questions par l\u2019acquisition de donn\u00e9es \u00e9chelonn\u00e9es sur plusieurs ann\u00e9es. La connaissance des sites de fraie permet \u00e9galement d\u2019\u00e9viter que ces habitats soient perturb\u00e9s par des activit\u00e9s humaines (comme des travaux en rive) pendant la p\u00e9riode critique de reproduction du poisson. Il est bon de savoir que les activit\u00e9s de p\u00eache r\u00e9cr\u00e9ative et commerciale au Qu\u00e9bec ne sont pas consid\u00e9r\u00e9es comme une menace pour le capelan, car les quantit\u00e9s r\u00e9colt\u00e9es sont faibles relativement \u00e0 l\u2019abondance de l\u2019esp\u00e8ce.[\/vc_column_text][nectar_cta btn_style=\u00a0\u00bbbasic\u00a0\u00bb heading_tag=\u00a0\u00bbh5\u2033

Pourquoi observer le capelan?<\/h2>\n

Les informations recueillies gr\u00e2ce au ROC pourraient \u00e9ventuellement contribuer \u00e0 la compr\u00e9hension de l\u2019impact des changements climatiques, de l\u2019\u00e9rosion des berges, ou des modifications des plages sur les habitudes de vie du capelan. Indirectement, cela am\u00e9liorera la connaissance que nous avons du fonctionnement g\u00e9n\u00e9ral de l\u2019\u00e9cosyst\u00e8me du Saint-Laurent.<\/p>\n

Les efforts pour suivre la fraie du capelan ont d\u00e9but\u00e9 en 2002 sur la C\u00f4te-Nord. En 2003, P\u00eaches et Oc\u00e9ans Canada (MPO) et diff\u00e9rents partenaires, tels des comit\u00e9s ZIP (Zones d\u2019intervention prioritaire) et des comit\u00e9s c\u00f4tiers, ont d\u00e9velopp\u00e9 un r\u00e9seau de contacts pour recueillir des donn\u00e9es pr\u00e9cises sur l\u2019activit\u00e9 de reproduction de cette esp\u00e8ce dans l\u2019estuaire et le golfe du Saint-Laurent.<\/p>\n

De 2002 \u00e0 2009, le nombre d\u2019observateurs et d\u2019observations du R\u00e9seau a \u00e9t\u00e9 en constante augmentation, ce qui a permis d\u2019avoir un aper\u00e7u de la distribution des aires de reproduction du capelan en milieu riverain. Cependant, la saison 2010 a \u00e9t\u00e9 moins riche en informations. Durant la saison 2011, le nombre d\u2019observations et d\u2019observateurs tendait \u00e0 remonter avec 66 observateurs signalant 184 observations. De plus, une nouvelle zone d\u2019observation, soit celle de Terre-Neuve-et-Labrador, a \u00e9t\u00e9 ajout\u00e9e. Les observations not\u00e9es depuis 1945 dans cette r\u00e9gion sont \u00e9galement int\u00e9gr\u00e9es au bilan.

Le capelan est une esp\u00e8ce cl\u00e9 de l\u2019\u00e9cosyst\u00e8me du nord du golfe du Saint-Laurent, car il en est la principale esp\u00e8ce fourrag\u00e8re (qui sert d\u2019aliment pour d\u2019autres esp\u00e8ces). Proie essentielle de la morue, le capelan fait aussi partie de l\u2019alimentation d\u2019une multitude d\u2019esp\u00e8ces marines : les fl\u00e9tans, plies, saumons, rorquals, b\u00e9lugas, dauphins, marsouins, phoques, fous de Bassan et autres oiseaux marins en consomment en grande quantit\u00e9. M\u00eame la morue franche le suit pr\u00e8s des berges pour s\u2019en alimenter.

Les \u0153ufs de capelan sont \u00e9galement un aliment important pour certains poissons, dont la plie rouge. Les \u0153ufs de capelan constituent une importante partie de leur di\u00e8te, en particulier chez les petites plies (de 14 \u00e0 34 cm de longueur), pour lesquelles ils repr\u00e9senteraient plus de la moiti\u00e9 (59 %) du poids des aliments ing\u00e9r\u00e9s.1<\/sup><\/p>\n

Malgr\u00e9 sa grande importance \u00e9cologique, le capelan du golfe du Saint-Laurent a fait l\u2019objet de peu de recherche. Beaucoup de questions primordiales demeurent sans r\u00e9ponse en ce qui concerne l\u2019\u00e9valuation de son abondance, la r\u00e9partition des diff\u00e9rentes populations, la localisation et la qualit\u00e9 des fray\u00e8res riveraines et d\u00e9mersales (sur les fonds marins). Ce manque de connaissances sur la biologie et l\u2019\u00e9cologie du capelan dans l\u2019ensemble du Saint-Laurent rend la gestion de l\u2019esp\u00e8ce plus ardue. Une plus grande quantit\u00e9 de donn\u00e9es sur la fraie du capelan permettrait d\u2019en tracer un portrait plus pr\u00e9cis.<\/p>\n

    Identification<\/h2>\n

    Le capelan est un petit poisson p\u00e9lagique de la famille des osm\u00e9rid\u00e9s (tout comme l\u2019\u00e9perlan arc-en-ciel) vivant en eau froide. Le capelan pr\u00e9sente une couleur olive. M\u00eame si tous les individus sont \u00e9lanc\u00e9s, le m\u00e2le et la femelle affichent des caract\u00e9ristiques physiques diff\u00e9rentes durant la p\u00e9riode de reproduction. Le m\u00e2le a des nageoires pectorales et anales surd\u00e9velopp\u00e9es qu\u2019il utilise pour s\u2019agripper \u00e0 la femelle et pour creuser le sol afin d\u2019y enterrer les \u0153ufs et la laitance. La femelle, de son c\u00f4t\u00e9, est reconnaissable \u00e0 son abdomen gonfl\u00e9 d\u2019\u0153ufs. En plus de ces caract\u00e9ristiques, le capelan d\u00e9tient une bande de poils sur sa ligne lat\u00e9rale, d\u2019o\u00f9 son nom latin, Mallotus villosus, signifiant villosit\u00e9 ou poil.[\/vc_column_text][image_with_animation image_url=\u00a0\u00bb1684\u2033 image_size=\u00a0\u00bbfull\u00a0\u00bb max_width=\u00a0\u00bb100%\u00a0\u00bb max_width_mobile=\u00a0\u00bbdefault\u00a0\u00bb animation_type=\u00a0\u00bbentrance\u00a0\u00bb animation=\u00a0\u00bbNone\u00a0\u00bb animation_movement_type=\u00a0\u00bbtransform_y\u00a0\u00bb hover_animation=\u00a0\u00bbnone\u00a0\u00bb alignment=\u00a0\u00bb\u00a0\u00bb border_radius=\u00a0\u00bb10px\u00a0\u00bb box_shadow=\u00a0\u00bbnone\u00a0\u00bb image_loading=\u00a0\u00bbdefault\u00a0\u00bb][vc_column_text css=\u00a0\u00bb\u00a0\u00bb text_direction=\u00a0\u00bbdefault\u00a0\u00bb]Capelans m\u00e2le (en haut) et femelle (en bas)<\/p>\n

    Selon les populations et les ann\u00e9es, sa taille peut varier consid\u00e9rablement. Dans les eaux du Saint-Laurent, les individus mesurent en moyenne de 13 \u00e0 20 cm, mais peuvent atteindre jusqu\u2019\u00e0 23 cm dans certaines r\u00e9gion. La taille des m\u00e2les est sup\u00e9rieure \u00e0 celle des femelles. Les capelans qui se trouvent le long de la c\u00f4te du Labrador ont une taille pouvant atteindre pr\u00e8s de 30 cm. La long\u00e9vit\u00e9 du capelan est \u00e9valu\u00e9e \u00e0 cinq ou six ans, et sa maturit\u00e9 sexuelle est atteinte vers l\u2019\u00e2ge de trois ans.<\/p>\n

    Lors de la p\u00e9riode de ponte des \u0153ufs, l\u2019abdomen des femelles se gonfle d\u2019\u0153ufs tandis que les nageoires ventrales des m\u00e2les s\u2019allongent et s\u2019\u00e9cartent du corps. Ces caract\u00e8res distincts apparaissent environ quatre \u00e0 cinq semaines avant le d\u00e9but de la fraie.
