Recreational fishing (i.e., angling), a popular leisure activity that provides socio-economic benefits to human societies around the world, can represent a significant source of fishing mortality and impact fish populations and marine ecosystems. Although fish are often released by recreational anglers to reduce fishing mortality rates, the efficacy of discarding fish is often criticized given that fish can die from the factors experienced during the capture, handling, and release process (i.e., discard mortality). Despite this recognition, the rate at which fish suffer discard mortality in specific commercial and recreational fisheries is often unknown and difficult to obtain due to logistical …

Fish have been an important food resource for humans throughout history, but with growing populations increasing the demand for this resource, many fish stocks have become overfished. In response, management has traditionally addressed overfishing by establishing regulations that reduce the directed fishing mortality associated with harvesting. However, these practices often do not take into account the mortality associated with fish that are incidentally captured and discarded (as bycatch). This discard mortality (DM) can represent a potentially large source of removals for species that are particularly susceptible to the stressors of capture-and-handling and/or discarded at high rates. It is therefore vital …
