dcterms.abstractIncreasingly targeted by commercial fisheries, the seven resident species of Northwest (NW) Atlantic skates possess life history traits that make them vulnerable to overexploitation, including slow growth, late maturation and relatively low fecundity. The various species occupy overlapping habitats and often migrate long distances. While their ecological role as benthic marine generalists and basic geographic ranges are understood, little is known about how they occupy available habitat relative to environmental and biotic factors. I statistically analyzed skate habitat preference using data collected by the National Marine Fisheries Service (NMFS) bottom trawl survey for 1963-2010. Using the nonparametric cumulative distribution approach of Perry and Smith (1994), I compared available and occupied habitat for each species. Significant associations were found for the environmental variables latitude, temperature, depth and salinity. Species-specific habitat associations and interspecific spatial interactions were estimated with emphasis on temporal variations. I discuss the implications of habitat preference for range overlap and interspecific competition. This study provides valuable insights into the spatial and temporal habitat use of skates and improves scientific understanding of skate ecology.
