Consumer preferences for sustainably sourced seafood: Implications for fisheries dynamics and management
通过生物经济模型和离散选择实验,量化消费者对可持续海鲜的偏好如何影响渔业动态,并得出高效渔业管理的启示。
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.
