渔民报告他们所有的渔获量是估计脆弱、高度迁徙鱼类种群种群生存能力的关键。然而，渔业管理者发现很难确保这种报告行为持续发生。野生大西洋鲑鱼(Salmo Salar)是一种高度迁徙和具有国际争议性的物种，处于受威胁的保护地位。格陵兰管理着大西洋三文鱼的渔业，其海岸线是大西洋三文鱼生活史上的关键喂食场。然而，尽管三文鱼捕获量被要求上报，但他们没有上报。通过惩罚和发送短消息服务(SMS)消息来威慑不遵守行为已被证明可以提高遵从性，但已知的研究没有测试它们对遵守渔获量报告要求的影响。我们评估了两种干预措施对格陵兰鲑鱼渔民的鲑鱼产量报告行为的影响。一旦实施了基于威慑的干预措施，鲑鱼渔民报告的可能性增加了41%(P<；0.00)。收到短信提醒的渔民报告鲑鱼捕获量的可能性要高出6%(p<；约0.1)。这些结果突出了督促和指挥控制干预措施的互补性，以提高对渔获量报告要求的遵守情况。
Fishers reporting all of their catch is key to estimating population viabilities of vulnerable, highly migratory fish stocks. However, fishery managers find it difficult to ensure that this reporting behavior takes place consistently. Wild Atlantic salmon (Salmo salar) are a highly migratory and internationally contested species with a threatened conservation status. Greenland manages a fishery for Atlantic salmon, and its coastline serves as a key feeding ground in the life history of Atlantic salmon. However, salmon catch is underreported by fishers, even though they are required to report. Deterring noncompliant behavior with penalties and sending short message service (SMS) messages have been shown to increase compliance, but no known studies test their effect on compliance with catch reporting requirements. We evaluated two interventions for their effect on salmon catch reporting behavior among Greenland's salmon fishers. Salmon fishers were 41% more likely to report (p< 0.00) once a deterrence-based intervention was implemented. Fishers who received SMS reminders were 6% more likely to report salmon catch (p< 0.1). These results highlight the complementarity of nudges and command-and-control interventions to increase compliance with catch reporting requirements.
