Although bonefish, Albula vulpes, supports a culturally and socio-economically important recreational fishery in the Caribbean Sea, little is known about their population characteristics. Understanding their population parameters are important for the creation of a sustainable fishery strategy in the Caribbean region. We used multistate modeling to estimate apparent survival, recapture probability, and movement of bonefish in the regions of Corozal-Chetumal Bay (CB) and the adjacent Caribbean coast (CC) of Belize and Mexico. We marked 9657 bonefish and recaptured 613 (6.5% recapture rate). A total of 64 multistate models were run in program MARK. The model with the lowest Akaike Information Criterion was the most parsimonious model that supported our data: constant apparent survival in CC but variable in CB; time-dependent recapture probability in CC and CB; and time-dependent movement between regions. The latter reflects a seasonal migration from the bay to spawn in the Caribbean during the north-winds season. The seasonal differences in apparent survival (CC = 63.6% and CB = 80.6%) and recapture probability (CC = 1.3% and CB =11.1%) are associated to spawning mortality, a post-spawning relocation, ontogenetic shift, predation, angling activities, site fidelity or a combination of these. These findings reinforces the association of environmental variables influenced by weather patterns with movement patterns, the entire region to be considered a single geographic catchment area necessary to sustain a local bonefish population and the need for a paradigm shift from a traditional to a new system of fisheries conservation and management using bonefish as an umbrella species.

在伯利兹和墨西哥,使用骨鱼(Albula vulpes)作为保护伞物种的渔业系统和保护区的保护和管理发生新转变

尽管硬骨鱼 Albula vulpes 支持加勒比海具有重要文化和社会经济意义的休闲渔业,但对其种群特征知之甚少。了解它们的种群参数对于在加勒比地区制定可持续渔业战略非常重要。我们使用多州建模来估计科罗萨尔-切图马尔湾 (CB) 以及伯利兹和墨西哥的邻近加勒比海岸 (CC) 地区的硬骨鱼的表观存活率、重新捕获概率和运动。我们标记了 9657 条骨鱼并重新捕获了 613 条(6.5% 的重新捕获率)。共有 64 个多状态模型在程序 MARK 中运行。具有最低 Akaike 信息准则的模型是支持我们数据的最简洁的模型:CC 中的表观存活率恒定,但 CB 中的可变;CC 和 CB 中的时间相关重新捕获概率;和区域之间的时间依赖运动。后者反映了在北风季节从海湾到加勒比海产卵的季节性迁徙。表观存活率(CC = 63.6% 和 CB = 80.6%)和重新捕获概率(CC = 1.3% 和 CB =11.1%)的季节性差异与产卵死亡率、产卵后迁移、个体遗传转移、捕食、钓鱼活动有关、网站保真度或这些的组合。这些发现加强了受天气模式影响的环境变量与运动模式之间的关联,
