Abstract:
The Sardine catch and presence grid dataset has been assembled directly from the Pelagics Data Unit -Sardine 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 estimated Catch (metric tonnes). The dataset is comprised of an aggregate of only sardines and specifically targets the 2001-2008 cumulative fishing seasons. The catch values are based on estimated total catch from harvesters logs and do not necessarily reflect the landed validated weight. Where catch data could not be displayed, the catch values and number of fishing licences have been removed so as not to comprise the proprietary knowledge of any individual harvester.
Purpose:
The purpose of the data is to display complete, up-to-date information on commercial Sardine fishing activities along the coast of British Columbia for the BCMCA Atlas and Marxan analyses, without jeopardizing the competitive nature of the fishery. This dataset developed with the financial assistance of the British Columbia Marine Conservation Analysis (BCMCA).
The British Columbia Marine Conservation Analysis (BCMCA) is a collaborative project assembling and analyzing spatial information about Canada's Pacific Ocean. The overall goal of the BCMCA is to identify marine areas of high conservation value and marine areas important to human use. Results of the project are intended to inform and help advance marine planning initiatives in BC by providing collaborative, peer-reviewed scientific analyses based on the best ecological and human use spatial data at scales relevant to a BC coast-wide analysis.
Supplemental_Information:
Due to the varibale nature of the data not all of the information in the database can be shown spatially. This dataset combines the original catch grid and presence grid for the sardine fishery.

Data_Quality_Information:
Logical_Consistency_Report:
Data has been cleaned using a dangle length of .001m and fuzzy tolerance of .0001m A 4km x 4km grid was used with an grid origin of: Easting -27940m, Northing 94650m To meet the sensitivity requirements of the Access to Information Act a count of 3 or more vessles (CFV field used), that were fishing within the same grid cell was used. To allow for more data to be shown the data was amalgamated across all years where accurate spatial information was provided.

Process_Description:
PROCESSING FOR THE CATCH GRID In ArcMap using Lon & Lat fields as XY coordinates created a shape file - Using XTOOLS XY field and coordinates were assigned. - Exported dbf file to uniquecfv.mdb database provided by Norm Olson (PBS) to populate index fields which were required to spatially sort unique Tab. XY fields were used to assign a point value associated with a unique grid value. Fields were than summed by catch to provide a summed value for each unique TAB in each grid. - Within ArcMap imported the new dbf file into ArcMap and use XY coordinates to map the points. - Spatially Joined the 4km x 4km grid to the point file. During the joining all fields are summed. A newly created Sum of Count field indicated number of unique vessels in the grid. - Select only those records that have a sum vessel count greater than 2. - Export selected records and create new shape file. - Eliminated all irrelevant fields keeping only the GridCell, #_vessels, Catch attribute items
