Abstract
Although artificial reefs are commonly used throughout the world as tools to mitigate for habitat alteration, their development is rarely subjected to a rigorous site selection process. We developed a simple site selection model using the following seven systematic steps: exclusion mapping, depth and slope verification, surficial substrate assessment, data weighting and the subsequent ranking analysis, visual transect surveys, benthic air‐lift sampling, and larval settlement collector deployment. American lobster (Homarus americanas) was selected as the target species for these investigations owing to the local commercial importance of the species. Results from each step in this process ultimately allowed us to select a site for an artificial reef at a target depth that received little wave action, had no slope, and possessed a surficial substrate type that could support the weight of a reef. The site also had the presence of a natural larval supply and low species diversity before reef installation. Each step in this site selection model was designed for easy adaptation to suit the needs of various artificial reef projects.Keywords
