Blennies and gobies are among the most abundant fishes in western Atlantic and Gulf of Mexico estuaries. They establish nests and maintain territories in oyster reefs and around other shallow-water structures during warm months. In this study, site fidelity and movements were determined for adult striped blenny, naked goby, freckled blenny, crested blenny, and feather blenny, in descending order of abundance. Recaptures among 221 tagged fishes at nine intertidal oyster reefs in a southeastern U.S. saltmarsh estuary provided information about fidelity for individual oyster reefs and nest sites as well as the size of territories (areas used) around nest sites. An overall recapture rate of 94% for fishes on reefs where they were tagged indicated high fidelity. Total recapture rates for the four blenny species ranged from 38 to 50%, but the naked goby recapture rate was only 9%. Within a breeding season, fidelity for specific nest sites was 58% for all blennies and 17% for gobies. Movements away from nest sites were limited with 56% of all fishes re-occurring ≤ 1 m from the original tagging site. Territories of < 5 m were identified for > 84% of the recaptured fishes. Differences in species composition and abundance between reefs suggested species-specific preferences for habitat features. Crested blenny and freckled blenny were recaptured at nest sites with significantly more oyster cover than nest sites occupied by striped blenny. Blennies occupied nest sites for several months and across annual breeding seasons suggesting continued residency within small areas of individual oyster reefs throughout their lives. Strong fidelity for reefs and nest sites potentially makes blennies more susceptible to disturbances than gobies, but both may be vulnerable to habitat disturbance at scales < 5 m. Thus, blennies and gobies may be useful indicator species for changes within estuarine habitats and ecosystems.

Saltmarsh潮汐溪中牡蛎礁布兰妮和虾虎鱼的现场保真度

布朗尼和虾虎鱼是西大西洋和​​墨西哥湾河口最丰富的鱼类之一。他们在温暖的月份在牡蛎礁和其他浅水结构周围筑巢并维护领土。在这项研究中，被确定为成年条纹粘鱼网站保真度和运动，裸虾虎鱼，粘鱼雀斑，凤头粘鱼，和羽毛粘鱼，以丰富度降序排列。在美国东南部盐沼河口的9个潮间牡蛎礁中的221条带标签的鱼类中的捕获，提供了有关单个牡蛎礁和巢穴保真度以及巢穴周围区域（使用区域）大小的信息。贴有标签的珊瑚礁鱼类的总体捕获率为94％，表明其保真度很高。四种粘鱼物种的总捕获率介于38％至50％之间，但裸虾虎鱼的捕获率仅为9％。在繁殖季节内，所有绒面的特定巢穴保真度为58％，虾虎鱼为17％。离开巢点的移动受到限制，所有鱼类中有56％的鱼从原始标签位置再次出现≤1 m。对于> 84％的重新捕获鱼类，确定了<5 m的领土。珊瑚礁之间物种组成和丰度的差异表明对栖息地特征的特定物种偏好。凤头的粘鱼和雀斑的粘鱼被重新捕获在牡蛎覆盖的巢区，比带状粘鱼占据的巢区多得多。Blennies在巢地占据了几个月，并在每年的繁殖季节中占据一席之地，这表明他们一生中一直在单个牡蛎礁的小区域内居住。珊瑚礁和巢穴的保真度较高，可能使浮游动物比虾虎鱼更容易受到干扰，但在小于5 m的规模上，两者都容易受到栖息地干扰。因此，绒毛和虾虎鱼可能是河口栖息地和生态系统内变化的有用指示物种。凤头的粘鱼和雀斑的粘鱼被重新捕获在牡蛎覆盖的巢区，比带状粘鱼占据的巢区多得多。Blennies在巢地占据了几个月，并在每年的繁殖季节中占据一席之地，这表明他们一生中一直在单个牡蛎礁的小区域内居住。珊瑚礁和巢穴的保真度较高，可能使浮游动物比虾虎鱼更容易受到干扰，但在小于5 m的规模上，两者都容易受到栖息地干扰。因此，绒毛和虾虎鱼可能是河口栖息地和生态系统内变化的有用指示物种。凤头的粘鱼和雀斑的粘鱼被重新捕获在牡蛎覆盖的巢区，比带状粘鱼占据的巢区多得多。Blennies在巢地占据了几个月，并在每年的繁殖季节中占据一席之地，这表明他们一生中一直在单个牡蛎礁的小区域内居住。珊瑚礁和巢穴的保真度较高，可能使浮游动物比虾虎鱼更容易受到干扰，但在小于5 m的规模上，两者都容易受到栖息地干扰。因此，绒毛和虾虎鱼可能是河口栖息地和生态系统内变化的有用指示物种。Blennies在巢地占据了几个月，并在每年的繁殖季节中占据一席之地，这表明他们一生中一直在单个牡蛎礁的小区域内居住。珊瑚礁和巢穴的保真度较高，可能使浮游动物比虾虎鱼更容易受到干扰，但在小于5 m的规模上，两者都容易受到栖息地干扰。因此，绒毛和虾虎鱼可能是河口栖息地和生态系统内变化的有用指示物种。Blennies在巢地占据了几个月，并在每年的繁殖季节中占据一席之地，这表明他们一生中一直在单个牡蛎礁的小区域内居住。珊瑚礁和巢穴的保真度高，可能使浮游生物比虾虎鱼更容易受到干扰，但在小于5 m的规模上，两者都容易受到栖息地干扰。因此，绒毛和虾虎鱼可能是河口栖息地和生态系统内变化的有用指示物种。
