Review and evaluation of fishing-related incidental mortality for Pacific salmon: Fs70-5/2017-010E-PDF

“Stock assessment methods for Pacific salmon (Oncorhynchus spp.) require estimates of total mortality to obtain accurate exploitation rate and stock size estimates. Total mortality includes both natural mortality and fishing-related mortality. The latter is composed of retained catch, plus any incidental mortality associated with fishing activities. Fishing-related incidental mortality (FRIM) includes mortality of fish that encounter fishing gear but are not captured (e.g., escape mortality), that are dead upon or die during capture but are not retained (e.g., on-board mortality), and that die after release (i.e., post-release mortality). Globally, FRIM has been recognized as a significant conservation concern for freshwater and marine fish, as well as other organisms (e.g., turtles and marine mammals). The objectives, as described in the Terms of Reference, to be covered in this research document are as follows: identify and discuss potential impacts of key factors that can influence FRIM for Pacific salmon; conduct a comprehensive review of the primary and grey literature that contains documented evidence (e.g., mortality rates) of FRIM for anadromous salmonids; and identify uncertainties and knowledge gaps in the information that is currently available to inform estimates of FRIM for Pacific salmon"--Introd., p. 1-2.
