摘要岸线改造，如舱壁、抛石和水上结构，改变了沿海城市周围近岸城市化地区的许多自然栖息地，包括华盛顿州普吉特湾的那些地区。这种结构对生态过程的影响知之甚少，特别是那些影响幼鲑鱼Oncorhynchus spp。我们研究的目的是比较鲑鱼幼鱼和其他鱼类在不同修改和未发育的海岸线类型上的相对丰度和行为。我们使用围网和浮潜调查在五种主要生境类型：鹅卵石滩、沙滩、延伸到潮间带上的抛石、延伸到潮下带的深水抛石和水上结构物的边缘，在涨潮时在靠近海岸的区域对鱼类进行采样。底栖鱼类的密度在鹅卵石滩、沙滩和延伸到潮间带上部的抛石之间表现出唯一显著的差异。这表明底物..。
Abstract Shoreline modifications, such as bulkheads, riprap, and overwater structures, have altered many of the natural habitats in nearshore urbanized areas surrounding coastal cities, including those in Puget Sound, Washington. The effects of such structures on ecological processes are poorly known, especially those impacting juvenile salmonids Oncorhynchus spp. The goal of our study was to compare the relative abundance and behavior of juvenile salmonids and other fishes along various modified and undeveloped shoreline types. We used enclosure nets and snorkel surveys to sample fishes during high tides in areas adjacent to shore at five main habitat types: cobble beach, sand beach, riprap extending into the upper intertidal zone, deep riprap extending into the subtidal zone, and the edge of overwater structures. Bottom-dwelling fishes exhibited the only significant differences in density among cobble beach, sand beach, and riprap that extended into the upper intertidal zone. This suggests that substrat...
