这项研究描述了海底特征和幼鱼群落结构，以提供定性鱼类栖息地评估。与海洋相关的利用和管理战略，从沿海开发和疏浚材料处置到渔业活动和海洋保护措施，往往影响海洋和河口栖息地和生命。海洋资源管理的一个主要组成部分是养护和保护海洋和河口栖息地，例如苗圃栖息地。制定有效的鱼类栖息地监测和评估对于实现保护、可持续发展和海洋利用管理战略之间的平衡至关重要。海洋和河口生物的个体发育取决于特定的环境属性，海底条件通常决定底栖大型动物的分布、丰度和组成。鱼类和十足目动物的底层幼体阶段、新定居和早期底栖阶段的生活史，尤其需要非生物和生物底栖资源来生存和生长。为早期生活史鱼类和无脊椎动物提供生产性环境条件的海洋和河口生境被称为育苗生境。底层幼鱼，如美洲龙虾、大西洋鳕鱼和岩枪鱼，表现出典型的以微生境属性和复杂底栖生物为特征的生态要求。海底环境呈现出影响一个地区生物学的多种资源和相互作用。移动和定居的大型动物已经进化出对具有特定属性的底栖生物的强制性和兼性依赖。描述海底的复杂性是检查底栖生物与生物关系的一种方法。海底的复杂性决定了地形结构和垂直地形，并基于沉积物类型、床层形态和生物结构。
This study described seafloor features and juvenile fish community structure to provide a qualitative fish habitat assessment. Ocean-related uses and management strategies, ranging from coastal development and dredged material disposal to fishery activities and marine conservation measures, often influence marine and estuarine habitat and life. A major component of ocean resources management entails the conservation and protection of marine and estuarine habitats, such as nursery habitat. The development of effective fish habitat monitoring and assessment is essential to achieving a balance between conservation, sustainable development and ocean-use management strategies. Ontogenetic development of marine and estuarine organisms depends on specific environmental attributes, and seafloor conditions often dictate the distribution, abundance and composition of bottom-dwelling macrofauna. Demersal juvenile stages of fishes and decapods, newly settled and early benthic phase life history-in particular, require abiotic and biotic benthic resources for survivorship and growth. Marine and estuarine habitats that present productive environmental conditions for early life history fishes and invertebrates are characterized as nursery habitats. Demersal juveniles, such as American lobster, Atlantic cod and rock gunnel, exhibit ecological requirements typically characterized by microhabitat attributes and complex benthos. The benthic environment presents diverse resources and interactions that influence the biology of an area. Mobile and sedentary macrofauna have evolved an obligatory and facultative dependence on benthos with particular attributes. Describing complexity of the seafloor is a method of examining benthos-organism relationships. Seafloor complexity shapes topographic structure and vertical relief and is based on sediment type, bed forms and biological structure.
