Appraising the resilience of Trochus and other nearshore artisanal fisheries in the Western Pacific

Foale, Simon

Abstract

Many coastal fisheries in the Indo-Pacific region are currently experiencing serious management problems with populations of a growing number of species showing steep declines. Trochus appears somewhat exceptional in this regard. It does not appear to be threatened with stock collapse in many places and, unlike some high-value invertebrates such as the green snail (Turbo marmoratus) and sea cucumbers (Holothuria scabra and Holothuria nobilis), appears to respond well to serial closures as commonly exemplified by the tambu or tapu system in many parts of Melanesia. In this short essay I wish to outline some of what I believe are plausible reasons for the relative resilience of trochus fisheries, and discuss what they imply for artisanal fishery management more broadly.
