RT Journal Article SR Electronic T1 Fishing under the Radar JF Land Economics FD University of Wisconsin Press SP 330 OP 352 DO 10.3368/le.101.3.022824-0019R1 VO 101 IS 3 A1 Bos, Björn YR 2025 UL http://le.uwpress.org/content/101/3/330.abstract AB This article evaluates the world’s largest fishing ban—the annual fishing moratorium in China—and assesses compliance with the ban. 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.
