Abstract
The management of many economically important reef-associated fish species is challenging due to difficulty sampling the rocky reef they inhabit and various life history characteristics leaving them vulnerable to exploitation (Coleman et al. 1999). commonly used sampling gears can be difficult to fish over rocky reef habitat and become snagged or damage the habitat. with the increase in underwater video sampling methods and the historical and still current use of traps for sam-pling, we compared chevron traps and underwater video for sampling temperate, rocky and coral reef habitats and reef fish communities. we used five years of comprehensive paired sampling data (n=7,034) collected over a large geographic area between north carolina and Florida along the southeast united states atlantic continental shelf, examining a large variety of fish species and families. to make comparisons, we examined frequency of occurrence of fishes caught in traps to those observed on video at both the family and species level and species richness between traps and videos.
