British Columbia Spot Prawn (Pandalus platyceros) Spawner Index

British Columbia Spot Prawn (Pandalus platyceros) Spawner Index Recruitment overfishing in the Spot Prawn (Pandalus platyceros) trap fishery in British Columbia on the west coast of Canada is managed using a fixed escapement system. Fixed escapement targets in the fishery are set and implemented as the number of female spawners caught per trap in the commercial fishery, obtained by monitoring the age and sex composition of the catch. Fishery independent sampling occurs during periods when the commercial fishery is closed to provide cohort abundance indices. See Boutillier, J.A. and J.A. Bond. 2000. Using a fixed escapement strategy to control recruitment overfishing in the shrimp trap fishery in British Columbia. [J. Northw. Atl. Fish. Sci](http://journal.nafo.int/Portals/0/2000-2/boutillier.pdf), Vol 27:261-271. Minimal spawner index data exists for the period 1985 through 1994, limited in both number of samples taken and location (south coast only) and are not presented in this dataset. In 1995 a new funding model allowed for a considerable (2 to 3 times) increase in Spring sampling activity, with coast wide coverage. Spawner index values are presented by date and location, where locations are described using Pacific Fishery Management (PFM) Area and Subarea. Sample season is defined as Winter (January, February, March), Spring (April, May, June), Summer (July, August, September) and Fall (October, November, December). Sample type may be R (conducted by DFO), C ( conducted by external parties)or E (conducted by DFO to undertake trap efficiency comparison studies). 2024-11-22 Fisheries and Oceans Canada Rob.Flemming@dfo-mpo.gc.ca Nature and EnvironmentScience and TechnologySpot PrawnPandalusRecruitment OverfishingFixed Escapement TargetPacificBritish Columbia Data DictionaryHTML https://api-proxy.edh.azure.cloud.dfo-mpo.gc.ca/catalogue/records/8c6581b4-0db9-4329-8018-a6fbcc7ad7f4/attachments/Data_Dictionary_EN_FR_BC_spot_prawn_SI.htm British Columbia Spot Prawn (Pandalus platyceros) Spawner IndexCSV https://api-proxy.edh.azure.cloud.dfo-mpo.gc.ca/catalogue/records/8c6581b4-0db9-4329-8018-a6fbcc7ad7f4/attachments/opendata_prawnsi_1995-2023_EN.csv British Columbia Spot Prawn (Pandalus platyceros) Spawner IndexCSV https://api-proxy.edh.azure.cloud.dfo-mpo.gc.ca/catalogue/records/8c6581b4-0db9-4329-8018-a6fbcc7ad7f4/attachments/opendata_prawnsi_1995-2023_FR.csv Data DictionaryPDF https://api-proxy.edh.azure.cloud.dfo-mpo.gc.ca/catalogue/records/8c6581b4-0db9-4329-8018-a6fbcc7ad7f4/attachments/Data_Dictionary_EN_FR_BC_spot_prawn_SI.pdf
