Background information and definitions
Trawling can lead to the capture large amounts of unwanted catch species. Animals caught in trawling nets can die from injuries sustained in the net, during handling, or when the catch is processed (Revill & Jennings 2005). Releasing live unwanted catch of subtidal benthic invertebrates before handling/processing the commercially targeted species may increase their chances of survival following release back into the water, because they would have been out of the water for less time.
