CLAM<\/SPAN>S <\/SPAN>- Average annual market value over 5 years (2008-2012) according to the actual landing and estimated values \u200b\u200bin the Estuary and Gulf of St. Lawrence.<\/SPAN><\/P>

The estimation methods consider the NAFO sub-areas and the % of georeferenced data. Depending on the species and NAFO sub-area, different methods have been used. The % of georeferenced data was generally under 70<\/SPAN>%<\/SPAN>for some \u201cSpecies/NAFO sub-area\u201d combinations: atlantic jacknife clam (4Tf), atlantic surfclam (4Tf) and arctic surfclam (4Sy, 4Sz and 4Tf). <\/SPAN>An estimation methodology has been used to directly assign a coordinated (PU = 6.25 km² cell - NAD 1983 Quebec Lambert Conformal Conic) to non-geoferenced landings and their values depending of the associated NAFO sub-area and in different PUs previously identified (see Lineage section for more details).<\/SPAN><\/P>

Because the % of georeferenced data for the NAFO sub-area 4Ra (arctic surfclam) was high enough (generally over 70 %), the values \u200b\u200b with coordinates were compiled in PUs. Afterward the compiled values were simply scaled by multiplying them by a coefficient based on the percentage of georeferencing in the NAFO sub-zone so the total reported in the PU reflect 100% of the landing values. <\/SPAN><\/P>

Finally, for most of the NAFO sub-areas concerning the atlantic surfclam and the atlantic jacknife clam 4Sy sub-area, no interpolation has been made, even though the % of georeferenced data was generally below 70 % (often 0%). No data on the spatial distribution of the species was available to provide a guideline for a random distribution and the landings values are too high to simply scale the value of each PU.<\/SPAN><\/P>

#Fra <\/SPAN>BIVALVES<\/SPAN>- Valeur commerciale annuelle moyenne sur 5 ans (2008-2012) selon les valeurs de débarquement réelles et estimées dans l\u2019estuaire et le golfe Saint-Laurent.<\/SPAN><\/P>

Les méthodes d\u2019estimation prennent en considération les sous-zones de l'OPANO et le % de données géoréférencées. Selon l'espèce et la sous-zone de l'OPANO, différentes méthodes ont été utilisées. <\/SPAN>L<\/SPAN>e % de données géoréférencées était généralement en dessous de 70%<\/SPAN>pour quelques<\/SPAN>combinaisons \"Espèce/Sous-zone de l'OPANO\"<\/SPAN>: couteau de l'atlantique (4Tf), mactre de l'atlantique (4Tf) et mactre de Stimpson (4Sy, 4Sz et 4Tf)<\/SPAN>. Une méthodologie d'estimation a donc été utilisée pour attribuer directement une coordonnée (PU = cellule de 6,25 km² - Conique Conforme de Lambert du Québec, Nad 83) aux débarquements non-géoréférencés et leur valeur en fonction de la sous-zone de l\u2019OPANO associée et dans différents PUs préalablement identifiés (voir section Lineage pour plus de détails). <\/SPAN><\/P>

Puisque le % de données géoréférencées pour la sous-zone 4Ra (mactre de Stimpson) était suffisamment élevé (généralement + de 70%), les valeurs possédant des coordonnées ont été compilées dans des PUs. Par la suite les valeurs compilées ont simplement été mise à l\u2019échelle en les multipliant par un coefficient basé sur le pourcentage de géoréférencement dans la sous-zone de l'OPANO de façon à ce que la valeur totale rapportée dans le PU reflète 100% des valeurs de débarquements.<\/SPAN><\/P>

Finalement, pour la majorité des sous-zones de l\u2019OPANO concenrnant le mactre de l'atlantique, ainsi que la sous-zone 4Sy du couteau de l'atlantique, aucune interpolation n\u2019a été effectué bien que le % de données géoréférencées était généralement bien en dessous de 70% (souvent 0%). Aucune donnée sur la distribution spatiale de l'espèce n\u2019était disponible pour donner une ligne directrice vers une distribution aléatoire et les valeurs de débarquements trop élevées pour simplement effectuer une mise à l\u2019échelle des valeurs de chaque PU. <\/SPAN><\/P>
