Increasing human populations and urban development have led to losses of estuarine habitats for fish and wildlife. Where resource managers are restoring coastal wetlands, in addition to meeting goals related to hydrologic connectivity, biodiversity, and recreational opportunities, efforts are being made to provide habitat that is suitable for juvenile sportfish. An 18‐month study was conducted to compare juvenile sportfish use of natural, restored, and impacted sites along Tampa Bay, Florida, shorelines. Juvenile sportfish densities at restored sites were broadly comparable to natural sites and greater than at impacted sites. However, site‐specific differences in sportfish use did occur within site types. For example, one restored site had significantly higher densities of red drum Sciaenops ocellatus than any other site, while black drum Pogonias cromis were found exclusively at another restored site. To evaluate whether the restored sites are providing suitable habitat for juvenile fish, we assessed growth (estimated from counts of daily rings on otoliths) and condition (determined by lipid analyses) of juvenile common snook Centropomus undecimalis, an archetypal coastal wetland‐dependent species. Growth (0.43–0.56 mm SL/day) and condition (4.6–6.1% lipid of dry weight) exhibited only site‐specific differences and did not vary among natural, restored, and impacted site types. Although mortality rates of juvenile sportfish were not determined, use of a 40‐m seine found that densities of potential piscine predators in these coastal wetlands were relatively low compared to published studies of open estuarine shorelines. The restoration and creation of coastal wetlands in Tampa Bay provides improved habitat for juvenile sportfish.

沿海湿地恢复改善了美国佛罗里达州坦帕湾的幼体运动鱼的栖息地

人口的增长和城市发展导致鱼类和野生动植物的河口栖息地减少。在资源管理者正在恢复沿海湿地的地方，除了实现与水文连通性，生物多样性和娱乐机会有关的目标外，还努力提供适合幼体鱼的栖息地。进行了为期18个月的研究，比较了在佛罗里达州坦帕湾，海岸线上自然，恢复和受灾地点的幼体鱼的使用情况。复原地点的幼体运动鱼类密度与自然地点大致相当，比受影响地点更大。但是，在场所类型内确实发生了特定地点的运动鱼使用差异。例如，一个恢复的地点的红鼓海豚（Sciaenops ocellatus）密度明显更高比其他任何地点都多，而黑鼓的Pogonias cromis仅在另一个恢复地点发现。为了评估是否恢复站点为幼鱼提供合适的栖息地，我们评估增长和条件（从耳石每日环数估计）（脂质分析确定）的少年共同斯努克Centropomus undecimalis是典型的沿海湿地物种。生长（0.43-0.56 mm SL /天）和状况（干重脂质的4.6-6.1％）仅表现出部位特异性差异，并且在自然，恢复和受影响的部位类型之间没有差异。尽管未确定幼鱼的死亡率，但使用40米长的围网发现，与已发表的开放河口海岸线研究相比，这些沿海湿地中潜在的鱼类捕食者的密度相对较低。坦帕湾沿海湿地的恢复和创造为幼体运动鱼提供了改善的栖息地。
