Dynamics of Heterogeneous Congestion Tolerance in the Location Choices of U.S. Gulf of Mexico Shrimp Fishermen AgEcon
Ran, Tao; Keithly, Walter R., Jr.; Kazmierczak, Richard F., Jr..
Location choice is one of the most important short-run decisions made by commercial fishermen. Previous studies of location choice by commercial fishermen have focused primarily on site fidelity, profit-maximization behavior, and risk attitudes as factors influencing their location choice behavior. Although the recreational literature gives extensive consideration to the influence of congestion on site selection, few studies have considered the influence of congestion tolerance on site selection in the commercial fishing sector. This study uses a mixed logit model to analyze the heterogeneous congestion tolerance in location choice among U.S. Gulf of Mexico shrimp fishermen. The dynamics of fishermen responses to economic conditions are compared and...

Location Choice Behavior of Gulf of Mexico Shrimpers under Dynamic Economic Conditions AgEcon
Ran, Tao; Keithly, Walter R., Jr.; Kazmierczak, Richard F., Jr..
This study uses a mixed logit model to analyze monetary and nonmonetary factors that influence location choice behavior of the U.S. Gulf of Mexico shrimpers. Shrimpers’ responses to economic conditions are compared and contrasted for two periods related to changing economic conditions in the industry. Results show that even though shrimpers are generally revenue driven in choosing a fishing site, their past experience also plays an important role. Further, changes in economic conditions appear to exhibit an influence on the risk attitudes of some shrimpers.

The recent trends and future prospects of shrimp fishery. OceanDocs
Adetayo, J.A..
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.

The role of mangrove in the French Guiana shrimp fishery ArchiMer
Diop, Bassirou; Sanz, Nicolas; Blanchard, Fabian; Walcker, Romain; Gardel, Antoine.
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...
