This is an interesting paper. You might want to take a look at Balon EK (2000) Defending fishes against recreational fishing: an old problem to be solved in the new millenium. Environ Biol Fishes 57:1–8. and Dionys de Leeuw (1996). Contemplating the interests of fish: The angler’s challenge. Env. Ethics 18:373-390. Classic papers that tackle some of the ethical issues around angling which might link quite well with the take home message that anglers need to treat their prey with respect and minimise needless waste.
