Competitive fishing tournaments can cause significant welfare harm to fish through handling stress, barotrauma and delayed mortality - reforms are improving outcomes.
Fishing tournaments concentrate the welfare harms of recreational angling into a competitive format that may exacerbate handling stress. Fish held in livewells for hours experience chronic stress from crowding, water quality degradation and temperature fluctuations. Barotrauma in species caught from depth causes painful gas expansion that may leave fish unable to swim normally after release. Research documents that delayed post-release mortality can be substantial even when fish appear to swim away normally. Reform measures including photo identification technology that eliminates livewell holding, mandatory use of venting tools for deep-caught species, and improved handling training for anglers can significantly reduce tournament-related fish welfare impacts.
