Current catch, weigh, and release (CWR) scoring methods for sport fishing tournaments (particularly bass fishing tournaments) are aimed at conserving and improving sport fisheries compared with catch and kill methods used many years ago. However, numerous studies have shown significant fish mortality are associated with the CWR method that varies with temperature, handling time and conditions, and severity of injuries associated with the initial catch (White, et al., 2007; Nelson. 1998).
