海洋保护区有潜力通过增加总产卵潜力或通过溢出、幼鱼和成鱼从保护区迁移到非保护区来提高渔业生产力。溢出效应一直是许多研究的焦点，也是促进海洋保护区效益获得公众支持的重要论据。然而，很少有研究探讨殖民化或迁移到海洋保护区的机制。本研究提供了直接的现场证据，证明运动潜水渔业的干扰可以提高附近海洋保护区中加勒比大龙虾的丰度，特别是在未受干扰龙虾密度相对较高的保护区中，大概是通过同种吸引力，龙虾遵循化学线索来到海洋保护区内未受干扰的地点。渔业干扰后的种群重新分布对海洋保护区的设计和应用具有影响。例如，规避风险的渔业管理策略可能会将保护区设在靠近密集捕捞区域的位置，以加强流动物种的溢出。
Marine reserves have the potential to enhance fisheries productivity by increasing total spawning potential or by spillover, the migration of juveniles and adults from reserves to non-reserve areas. Spillover has been the focus of many studies and has been an important argument in promoting the benefits of marine reserves to gain public support. Few studies, however, have examined mechanisms for colonization or migrations into marine reserves. The present study provides direct field evidence that disturbance from a sport diving fishery can elevate the abundance of Caribbean spiny lobster Panulirus argus in nearby marine reserves-particularly in reserves containing relatively high densities of non-disturbed lobsters-presumably through conspecific attraction where lobsters follow chemical cues to undisturbed sites in marine reserves. Population redistribution following fishery disturbance has implications for marine reserve design and application. For example, risk-averse fishery management strategies might locate reserves adjacent to intensely fished areas to enhance spill-in of mobile species.
