About this dataset
The Stewardship Baseline Objectives Tool (SBOT) is a visualization and assessment tool to clarify and communicate baseline information and stewardship objectives for priority resource values. Currently, the tool is developed for the South Coast Region. The intent of the tool is to assess the current, past and future state of stewardship objectives to support operational, tactical and strategic management decisions for these priority resource values. The White Sturgeon (Acipenser transmontanus) is the largest freshwater fish species in North America with some individuals reaching over 100 years of age and over six metres in total length. In British Columbia and Canada, there are only six known spawning populations inhabiting the Fraser, Columbia and Kootenay River systems. The lower Fraser population is the largest and has many life history strategies because of its unimpeded access to in-river, marine and large lake habitats. This provides for an amazing opportunity to study White Sturgeon and monitor the lower Fraser population under relatively natural conditions, but also poses extra challenges. In the lower Fraser, Pitt and Harrison River systems, White Sturgeon occupy all available habitats including the estuary, main and side channel areas, and the large and small connected lakes. Because they are late maturing and long lived with life-long reproduction, specific habitat use varies by life stage, season, and prey availability. White Sturgeon feed on an abundance of prey organisms depending on their life stage, including benthic invertebrates such as crustaceans and molluscs, and all fish and their spawn, including Eulachon and all five Pacific salmon species. They are very particular about the habitats they choose for spawning, rearing, feeding and overwintering and their timing of use. In winter, they gather in several deep pools to congregate and from late-May through mid-July in the gravel reach to spawn, with their tiny larvae rearing initially in these same areas. ## Data used in the White Sturgeon SBOT: Acoustic Stations - https://catalogue.data.gov.bc.ca/dataset/d44bf9de-1ec3-4048-8dd6-0d33629a91a6 Catch & Effort Reporting Sections - https://catalogue.data.gov.bc.ca/dataset/b90c20d8-5ec8-4ba0-a776-c7ecc3069b78 Eulachon Spawning Habitats - https://catalogue.data.gov.bc.ca/dataset/e9c2951c-8c22-4a0e-b462-7cf9a8ac1e23 Habitats - https://catalogue.data.gov.bc.ca/dataset/5b4ab2d7-2900-4a7f-bf81-8ecac1adf16b Juvenile Catch - https://catalogue.data.gov.bc.ca/dataset/f83208f2-8ccd-4c43-8861-aa0323224015 Kilometre Points - https://catalogue.data.gov.bc.ca/dataset/f16cea5a-2f45-4e0a-bf24-7e1ea509b0b9 Major Projects - https://catalogue.data.gov.bc.ca/dataset/5ee75843-06b3-4767-b6c2-3248289f5e8d River Divisions - https://catalogue.data.gov.bc.ca/dataset/6d256cb3-cc48-42ae-819b-be23f0c07f69 Spawning Survey Sites - https://catalogue.data.gov.bc.ca/dataset/ca0338ba-5a53-4878-98f5-f4d562e2220b Water Approval Points - https://catalogue.data.gov.bc.ca/dataset/8b5492a7-b224-43e4-9684-9f16130cd3ec Water Rights Applications - https://catalogue.data.gov.bc.ca/dataset/f3a53d7f-da09-4726-ac83-f0032e4bd490 Water Rights Licences - https://catalogue.data.gov.bc.ca/dataset/5549cae0-c2b1-4b96-9777-529d9720803c White Sturgeon Adult & Sub-Adult Habitats - https://catalogue.data.gov.bc.ca/dataset/bcc60004-d348-4bbb-8960-7d60b96f4c5a White Sturgeon Juvenile Habitats - https://catalogue.data.gov.bc.ca/dataset/fb5a8d6a-e4f7-40fb-addc-b8a32471ee29 White Sturgeon Spawning Closures - https://catalogue.data.gov.bc.ca/dataset/8fc5f13d-88df-45a2-9c03-853cce4213df White Sturgeon Spawning Habitats - https://catalogue.data.gov.bc.ca/dataset/e08d4b9b-062c-4076-a790-9274923bdb3b
