The muricid gastropods Concholepas concholepas (loco or false abalone), endemic to Chile and Peru, and Haliotidae Haliotis spp. (abalone) are highly priced seafood delicacies traded in Asian markets. Historical catches, management strategies, production, prices, and revenues are analyzed for these wild and farmed gastropods. Wild abalone prices have a positive effect (P < 0.01), landings a negative effect (P = 0.01), and farmed aquaculture production a negative effect (P = 0.09) on Chilean loco export prices. This underscores the high degree of market integration and the direct price relationship for these gastropods between Chilean and the Asian seafood markets. Drops in the Chilean export prices of locos had a negative effect on official loco landings in Chile, affecting the small-scale territorial user rights for fishery comanagement scheme developed for the species. The study shows evidence of distal connections (telecoupling) between production and market forces, that can jeopardize fishery management efforts. Aquaculture being developed in certain parts of the world can impact quite specifically on the attempts to achieve sustainable fisheries in other geographically distinct areas. Because of large market fluctuations, and a global drive to develop large-scale farming of marine gastropods, there is an urgent need to strengthen the adaptive capacity for diversification, and to add value to resources, so as not to hamper the long-term development of traditional coastal fishing communities.
