RENT DRAIN ESTIMATION OF THE THAI FISHERIES IN THE GULF OF THAILAND

摘要

The fishery resources in the Gulf of Thailand have been subjected to excessive levels of fishing effort since perhaps as long as two to three decades. This has caused a change in catch composition with a higher share of short-lived species. The influence of this change on the value of the catch has not been unambiguously negative because some short-lived species fetch a good price. This notwithstanding, the paper shows significant rent losses associated with overfishing and greatly excessive fleet sizes in the Gulf of Thailand for all three of the studied fisheries, namely for demersal resources, Indo-Pacific mackeral and anchovy.
