For commercially important permits and pompanos, scant official information exists on fishery assessments, the reproductive seasonality and location of these species, which impede knowing the intensity of fishing pressure imposed at their spawning grounds. Fishers have acquired a substantial body of knowledge on these species as a result of their exploitation, which typically occurs at spawning aggregation sites. Because efficient fishery management relies on knowing the locations and time of spawning of exploited species, deficiencies of such information may impair the establishment of sustainable exploitation strategies. Here, we analyzed the data of permits (Trachinotus falcatus) and great pompanos (Trachinotus goodei) along the Brazilian coast, from small-scale (SSF) and recreational (RF) fishers that voluntarily shared their data (i.e., logbooks, images, movies), enabling us to track these aggregations and the resulting fishing pressure. Furthermore, to directly assess the impact that local fishing may have on these aggregations, we monitored the great pompano in Todos os Santos Bay (TSB). In TSB, high catches occurred at four sites known by fishers to harbor fish aggregations. We showed that abundant landings of these species are associated with SSF and RF, typically targeting ‘trophy’ individuals. Furthermore, expanding the web-based and logbook data through modeled catch estimates, we found high probability of catching these species during spawning aggregations. Fishers exert pressures on these populations given their awareness of the location and timing of these species’ aggregations. Collaborating with fishers and obtained their engagement toward guiding conservation-oriented fishery management at spawning grounds remains a highly sought-after goal.

对于商业上重要的许可证和鲇鱼，关于渔业评估、繁殖季节性和这些物种的位置的官方信息很少，这阻碍了了解在其产卵场施加的捕捞压力的强度。由于这些物种的开发，渔民获得了关于这些物种的大量知识，这通常发生在产卵聚集地。由于有效的渔业管理依赖于了解被开发物种产卵的地点和时间，因此此类信息的不足可能会影响可持续开发战略的制定。在这里，我们分析了许可（Trachinotus falcatus）和大鲳（Trachinotus goodei ）的数据) 沿巴西海岸，来自自愿共享其数据（即日志、图像、电影）的小规模 (SSF) 和休闲 (RF) 渔民，使我们能够跟踪这些聚合和由此产生的捕捞压力。此外，为了直接评估当地捕鱼可能对这些聚集产生的影响，我们监测了托多斯桑托斯湾 (TSB) 的大鲳鱼。在 TSB，渔民已知的四个鱼群聚集地出现了高捕获量。我们表明，这些物种的大量登陆与 SSF 和 RF 相关，通常针对“奖杯”个体。此外，通过模拟捕获量估计扩展基于网络的日志数据，我们发现在产卵聚集期间捕获这些物种的可能性很高。鉴于渔民了解这些物种聚集的位置和时间，他们对这些种群施加了压力。与渔民合作并获得他们参与指导产卵场的保护性渔业管理仍然是一个备受追捧的目标。
