| This paper investigates the role of mangrove as an habitat in the evolution of the French Guiana shrimp stock to explain the recent collapse of shrimp production. To achieve our aim, we use the open access fishery model developed by Barbier and Strand [1998. “Valuing Mangrove-Fishery Linkages-A Case Study of Campeche, Mexico.” Environmental and Resource Economics 12: 151–166] and integrate mangrove surface into the shrimp natural growth function. This enables to account directly for the effects of mangrove surface changes on the stock dynamics and thus production. Our results indicate that financial losses in the French Guiana shrimp fishery increase when mangrove surface decreases and are mitigated when mangrove surface increases. We show that changes in... |

| Between 1969-1980, the annual shrimp catch ranged from 585 to 21116 tonnes. The percentage of shrimp in the total catch showed a sharp decline from 75% in 1969 to 18% in 1979 while the fish by-catch rose from 25% to 82. The shrimps were abundant during the rains (April to September). The number of shrimpers and effort rose by 338% and 337% respectively. The mean annual catch per unit effort (cpue) ranged between 0,196 in 1972 and 0.365 (tonne per day out of (port) in 1975. Japan, United States of America, and Britain are the main importers of Nigerian shrimps. |
