Fish holding areas (i.e. areas of concentration of salmon and herring, both adult and juvenile) in coastal British Columbia. Attribute information includes overall relative importance, species of salmon and other fish observed at various times throughout the year as well as information on spawning activity and larvae. CRIMS is a legacy dataset of BC coastal resource data that was acquired in a systematic and synoptic manner from 1979 and was intermittently updated throughout the years. Resource information was collected in nine study areas using a peer-reviewed provincial Resource Information Standards Committee consisting of DFO Fishery Officers, First Nations, and other subject matter experts. There are currently no plans to update this legacy data.

Health Authority (HA) boundaries; 2022 boundary configuration. The HAs are a mutually exclusive and exhaustive classification of the land area in BC. HAs are contiguous (land area is geographically adjacent) and fit within an existing geographical hierarchy, e.g., cannot violate lower-level geography boundaries such as the Health Service Delivery Areas (HSDA) and Local Health Area (LHA).

PURPOSE:The purpose of this work was to determine (1) how the population genomic structure relates to gut microbiota composition of White Hake (Urophycis tenuis), and (2) whether microbiota community variation provides complementary insights into population structure of this species in eastern Canada.DESCRIPTION:Integrating host-associated microbiota with genomic approaches offers an opportunity to better understand the multiple biological dimensions shaping population structure in marine fishes. A clear understanding of population structure and dynamics is essential for informed fisheries management and conservation decisions; however, while genomic approaches have greatly improved our ability to delineate biological populations, they provide only a partial representation of biological structure, as patterns of differentiation reflect both historical divergence and contemporary ecological conditions. Host-associated microbiota can influence population-level ecological processes by contributing functional, potentially heritable variation that shapes host phenotype and fitness.In this study, we combined genotyping-by-sequencing with 16S rRNA gene amplicon sequencing to examine how population genomic structure relates to gut microbiota composition and to evaluate whether microbiota community variation provides complementary insights into population structure in White Hake (Urophycis tenuis) in eastern Canada. Genomic analyses identified two populations with greater spatial overlap than previously reported. Variation partitioning revealed that host genetics explained a negligible proportion of microbiota variation compared to environmental factors and fish length, suggesting that ontogenetic shifts in habitat use and resource acquisition influence gut microbiota composition. Several taxa were differentially abundant among fish length categories used as a proxy for diet, including taxa with chitin-degrading potential such as Photobacterium and Lachnospirales, which were enriched in smaller fish known to consume a crustacean-dominated diet. Together, these results indicate that gut microbiota composition in White Hake primarily reflects ecological and life-history processes rather than host population structure. PARAMETERS COLLECTED:Environmental parameters were also collected at most sampling sites, including depth, water temperature, oxygen and salinity levels.PHYSICAL SAMPLE DETAILS:Fin samples were collected to characterize the fish genotypes. Intestine (rectum) samples were collected to study fish gut microbiome.SAMPLING METHODS:In 2022 and 2023, White Hake were sampled during Fisheries and Oceans Canada (DFO) annual bottom trawl ecosystem monitoring surveys.USE LIMITATION:To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.

The Canadian Food Inspection Agency (CFIA) established a regulated area as part of its efforts to eradicate the Asian longhorned beetle (ALHB). With the regulation of this area, there are restrictions on the movement of nursery stock, trees, logs, lumber, wood, wood chips and bark chips from certain deciduous trees identified as hosts of the ALHB and firewood of all species. These restrictions are necessary to prevent the spread of the ALHB. This protects Canada's environment and forest resources, and also helps keep international markets open to the forest industry and nurseries in non-regulated parts of Ontario and in the rest of Canada.
