I begin by estimating the reduction in fishing effort resulting from the ban, using vessel broadcast positions and fishing boat detections from nighttime lights. The analysis reveals a reduction in fishing activity of up to 90%. I then investigate the characteristics of noncompliant vessels and their responses to the policy: fishers increase catches during evenings and nights, disable vessel broadcast devices, and engage in more transshipment events. I find that attractive income opportunities during the ban undermine compliance.
