Ecosystem-based management requires sound information on the distribution and abundance of species both common and rare. Therefore, the accurate identification for all marine species has assumed a much greater importance. The identification of many skate species is difficult as several are easily confused and has been found to be problematic in both survey data and fisheries data collection. Identification guides, in combination with training and periodic validation of taxonomic information, improve our accuracy in monitoring data required for ecosystem-based management and monitoring of populations. This guide offers a comparative synthesis of skate species known to occur in Atlantic Canada and adjacent regions....

The Shrimp Trawl catch and effort grid dataset has been assembled directly from the Shellfish Stock Assessment harvest log database located at the Pacific Biological Station (PBS). The dataset has been modified to meet the sensitive nature of the data as per the Access to Information Act20(1)(b,c); which specifies that Fisheries and Oceans Canada will not disclose to a third party confidential information that may prejudice the competitive position of the fisher, in which fishing location has been identified as one of the entities to be protected. There was a 4km x 4km grid used in the desensitization process as well information was limited to total Effort (tow hrs) and total Catch (lbs). The dataset is comprised...

Monitoring of aquatic invasive species (AIS) directly addresses one of the key activities outlined in the Implementation Strategy of the National Action Plan to Address the Threat of Aquatic Invasive Species in Canada. In order to make efficient use of limited resources, priority species, vectors and locations needed to be determined. This was done in three workshops held in three zones in Canada: Pacific, Atlantic, and Central and Arctic zone. The Central and Arctic zone was defined as the fresh- and marine (Arctic) waters of Alberta, Saskatchewan, Manitoba, Ontario, Nunavut and the Northwest Territories, and the freshwaters of the St. Lawrence River in Quebec. Prior to the Central and Arctic zone workshop (held...

The Pink Shrimp catch and effort grid dataset has been assembled directly from the Shellfish Data Units harvest log database located at the Pacific Biological Station (PBS). The dataset has been modified to meet the sensitive nature of the data as per the Access to Information Act20(1)(b,c); which specifies that Fisheries and Oceans Canada will not disclose to a third party confidential information that may prejudice the competitive position of the fisher, in which fishing location has been identified as one of the entities to be protected. There was a 10km x 10km grid used in the desensitization process. As well information was limited to total Effort (kilometre) and total Catch (lbs). The dataset is comprised...

There was a 4km x 4km grid used in the desensitization process as well information was limited to total estimated Catch (metric tonnes). The dataset is comprised of an aggregate...
Bigheaded carps (Bighead and Silver carps) are considered a potential threat to the Great Lakes basin. A binational ecological risk assessment was conducted to provide scientifically defensible advice for managers and decision-makers in Canada and the United States. This risk assessment looked at the likelihood of arrival, survival, establishment, and spread of bigheaded carps to obtain an overall probability of introduction. Arrival routes assessed were physical connections and human-mediated releases. The risk assessment ranked physical connections (specifically the Chicago Area Waterway System) as the most likely route for arrival into the Great Lakes basin. Results of the risk assessment show that there is enough...

Grass Carp (Ctenopharyngodon idella) is an herbivorous, freshwater fish that was first introduced in the United States in the early 1960s for use in biological control of aquatic vegetation. It has since escaped and dispersed through the Mississippi River basin towards the Great Lakes. To characterize the risk of Grass Carp to the Great Lakes basin, a binational ecological risk assessment of Grass Carp was conducted.This risk assessment covered both triploid (sterile) and diploid (fertile) Grass Carp and assessed the likelihood of arrival, survival, establishment, and spread, and the magnitude of the ecological consequences within 5, 10, 20 and 50 years from 2014 (i.e., the baseline year) to the connected Great...

Stream temperature data will be compiled from federal and provincial government agencies, as well as other data holders in British Columbia which will be housed in an interagency database. Spatial statistical models for river networks like those used for NorWeST will be used with these data to develop a consistent set of high-resolution predictions for all streams and reaches within streams for a pilot area within the Cascadia ecotypic area of the GNLCC (i.e., middle Fraser River and Okanagan River basins). The pilot area work would entail development of technical protocols so that future efforts could be scaled broadly across BC and the northern half of the GNLCC to ultimately provide a consistent set of international...
