Shrimp survey and resulting management actions, Fraser River shrimp management area, August 1998 / by J.A. Boutillier, J.A. Bond, H. Nguyen, and K. West.: Fs97-4/2494E-PDF

"This report forms part of a series that details the assessment and management actions undertaken in the shrimp trawl fisheries off the Pacific coast of Canada in 1998. An area-swept shrimp trawl survey was undertaken in the Fraser River Shrimp Management Area (FR SMA) in August, 1998. The DFO research vessel Caligus was used to complete the survey, which covered portions of Pacific Fisheries Management Areas (PFMA) 28 and 29. The fisheries in this area are primarily for the smooth pink shrimp, Pandalus jordani, the Northern pink shrimp, Pandalus borealis eous, and the sidestripe shrimp, Pandalopsis dispar. Biomass indices of shrimp by species were determined in select trawlable areas of the FR SMA. While the collection of shrimp data and the bycatch of halibut and eulachon were priorities over detailed information on bycatch, catch information on all species was collected. Landings of prawns were minor, and no halibut or eulachon were caught during the survey. Because of conservation concerns, a fixed exploitation rate of 25% (as opposed to the standard exploitation rate of 33%) was applied to the biomass estimates of shrimp by species. Catch ceilings, quotas, and other management actions as results of the survey are discussed. These survey data are the first data in developing a time series of survey indices for the area. This survey data set will complement established logbook and biological sampling data sets from the area and will be used in combination to provide an assessment of the health of the stocks in the area. Until a long-term database is available, the initial survey biomass indices will be used as absolute estimates for the purpose of setting quotas"--Abstract, page iii.
