- Abstract:
-
The Sardine catch 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 cummulative fishing seasons. The catch values are based on estimated total catch from harvesters logs and do not necessarily reflect the landed validated weight.
- 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). Catch data are presented as 2 km x 2 km planning units for MARXAN analysis.
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 variable nature of the data not all of the information in the database can be shown spatially. Note that this dataset includes information from catch data and does not include information from grid cells where catch data was restricted due to confidentiality constraints. These presence-only grid cells are shown with the catch grid cells in the BCMCA feature data for the sardine fishery.

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:
-
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

- Process_Description:
-
The individual datasets for Salmon (Chinook, Chum, Coho, Pink, Sockeye), Dungeness Crab, Geoduck, Green Sea Urchin, Groundfish Trawl, Halibut, Herring Roe, Humpback Shrimp, Krill, Pink Shrimp, Prawn, Red Sea Urchin, Sablefish (longline and trap), Sardines, Schedule II, Sea Cucumber, Sidestripe Shrimp and Rockfish Hook and Line were processed following a defined set of parameters and then combined together to provide a per planning unit catch for each individual fishery.
Processing Steps for data are as follows:
1. Have a clean PU file with only the Unit_ID
2. Make sure projection is in NAD 83 Environment Albers
3. Union the PU file with the fishery
4. Remove any polygons outside the study area
5. Add New_Area field + calculate the area in square meters
6. Determine Frequency (Toolbox>Analysis>Stats>Frequency) where the input is the unioned shapefile, the frequency file is FID_commer and the summary field is New_Area
7. Join the Frequency table to the Union Output (FID_commer to FID_commer)
8. Export joined file with new name (use _v2 at the end)
9. Add new field (Catch_PU) as a Double
10. Calculate the Catch per PU: Catch x New_Area / New_Area1
11. Open up the dbf in Excel and save as .xlsx.
12. Insert Pivot Table, Select Unit_ID as the row label and Catch_PU as the ? values. Then select all values for Catch_PU and copy and paste special (values) into new excel worksheet.
13. In Excel, generate full commercial fisheries table by selecting the values from the individual excel worksheets, providing the proper coding, and ensuring the numbers are correct.
14. Save completed fisheries database in Excel as .xlsx, Open the table in Microsoft Access, and re-save as a .dbase IV
15. Open the new .dbf in ArcInfo and join the commercial fisheries table to a clean PU file
