Consumer preferences for sustainably sourced seafood: Implications for fisheries dynamics and management

Abstract Many fish consumers reveal a preference for sustainably sourced seafood in their purchasing decisions. We propose a bioeconomic modeling approach and an empirical strategy, based on a discrete choice experiment, to quantify the resulting effects on fishery dynamics and to derive implications for efficient fishery management. We show that a “consumer stock effect” arises, which stabilizes a fishery under open access and which decreases catches under economically efficient management. We quantify these effects for the Western Baltic cod fishery.
