- Abstract:
-
The Humpback Shrimp catch 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 of Humpback Shrimp only and specifically targets the 1997-2004 fishing season (April-March). Effort data was dropped from the merged dataset.
- Purpose:
-
The purpose of the data is to display complete, up-to-date information on commercial Humpback Shrimp fishing activities along the coast of British Columbia for the BCMCA Atlas and Marxan analyses. This dataset was originally developed in fulfillment of a request by the Oceans Action Plan (OAP) committee with the intent to contribute to management plans within the Pacific North Coast Integrated Management Area (PNCIMA). It was subsequently provided to 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:
-
All fishing locations were derived for coordinates that have been provided by fishermen. In each the years from 1997 to 2004 between 85.2% & 99.1 of the data had latitude & longitude which could be mapped.
Due to the sensitive nature of the data not all of the information in the database can be shown spatially. In each the years from 1997 to 2004 between 62.3% & 94.7% of the data in the database met sensitivity requirements.

A total catch in pounds per species using the Humbacks field from the ShrimpLogs database
- Logical_Consistency_Report:
-
Data has been cleaned using a dangle length of .001m and fuzzy tolerance of .0001m
A 10km x 10km 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 vessels (CFV field used), that were fishing within the same grid cell and within the same fishing season (Year field used) was used

-
- Process_Description:
-
- In ArcMap "Add xy Data" using the Lon & Lat fields from the ShrimpLog database
- Export the event data to create a point shapefile
- Define Projection of the exported ShrimpLog shapefile to Geographic Coordinates (Fishermen supplied coordinates)
- Reproject ShrimpLogs shapefile to Nad83 Albers
- Within ArcMap imported the new Albers Shrimplog points and 10km x 10km grid polygonal shapefile
- Eliminated those arrant points not falling within the Pacific Coastline from Shrimplog shapefile. Errors mostly due to invalid coordinates provided by fishermen
- Joined the 10km x 10km grid to the ShrimpLogs point file based on they're "Spatial Location"
- Exported the attribute table from the output shapefile from the join and imported the DBF into the Sensitive.mdb database
- Used the "percentLat_deg" query to calculate the percentage of records with Lat & Longs coordinates for the given season per species noting the results
- Selected the interested season in the "SLicensestep0" query saved & the closed the query
- Selected the interested species in the "sLicenseStep2" query saved & the closed the query
- Ran the "ShrimpMacro" in the Sensitive.mdb
- Recorded the percentage of data used that met the sensitivity requirements
- Exported the results of the Macro as a DBF file
- In ArcMap imported the resultant DBF file and joined it to the 10km x 10km grid shapefile using "GridC"(from DBF) & "GridCell"(from 10km x 10km grid) as the join
field. Using the "Advanced" option when joining that only includes the joined records
- Converted the 10km x 10km grid to a shapefile to make the join permanent
- Eliminated all irrelevant fields keeping only the GridCell, Effort_km and Catch_lbs attribute items
- All queries pertaining to the creation of this dataset have been housed in \\Apnpacrhq01\PNCIMA\Draft_MUA_maps\Invertabrate_Maps\data\sensitive.mdb
