Global warming and the collapse of the French Guiana shrimp fishery

Abstract

This paper studies the biological and economic effects of global warming on the French Guiana shrimp …fishery. The sea surface tem- perature is explicitly introduced into four natural growth functions, among which the Cobb-Douglas function best adjusts the available data. Besides, a Cobb-Douglas harvest function is also estimated, in- dicating that shrimp production in French Guiana is highly sensitive to the shrimp stock, which implies that global warming may have strong economic implications. We …nally consider a centralized resource man- agement of the French Guiana shrimp …shery, that is undertaken in various trend scenarios concerning the sea surface temperature. Un- der the most plausible scenario, in which the sea surface temperature follows the trend of the last decades, pro…ts and biomass respectively decrease and collapse around the end of the 2020’s.
