More progressive management approaches have been adopted during this time, and many rockfish species, including cowcod, now appear to be rebuilding. This rebuilding has recently translated into increased cowcod catches by both recreational and commercial fishers, and the use of descending devices has become a popular method for releasing these fish with as little harm as possible. However, post-release mortality of cowcod associated with the use of these descending devices is still unclear. We have tagged __ adult individuals using acoustic telemetry methods, and analyses of these movement data are currently underway. We will also tag juvenile and sub-adult cowcod in an effort to estimate size-dependent post-release mortality and movement patterns. This will give us a better understanding of the rebuilding status of the species, and how changes in fishing regulations might affect this rebuilding. Recent population assessments of cowcod suggest the species is rebuilding, and increased interactions with commercial and recreational fisheries also suggest increasing numbers of cowcod. However, it is unclear how these increased catch-and-release events translate to impacts on the stock, and how changes in fishing depth restrictions might affect cowcod mortality. We will use acoustic telemetry to measure post-release mortality and movement patterns of cowcod, as well as the effectiveness of descending devices for releasing individuals back to depth. underDevelopment Hyde, John R (858) 546-7086 (858) 546-7003 8901 La Jolla Shores Dr La Jolla CA 92037 USA John.Hyde@noaa.gov 8:00 AM - 4:30 PM pointOfContact Hyde, John R (858) 546-7086 (858) 546-7003 8901 La Jolla Shores Dr La Jolla CA 92037 USA John.Hyde@noaa.gov 8:00 AM - 4:30 PM custodian asNeeded barotrauma rockfish theme post-release mortality temporal acoustic telemetry movement patterns place DOC/NOAA/NMFS/SWFSC > Southwest Fisheries Science Center, National Marine Fisheries Service, NOAA.
