Abstract

The spiny dogfish, Squalus acanthias, is a commercially important, circumboreal species of shark. However, very little information concerning the early life history of this species exists, especially along the US east coast. Elucidating the habitats that are critical for survival at this stage is essential for the effective management of this species. During a routine research cruise on February 5, 2012, three out of five short duration bottom otter trawls conducted within a 4.2km2 sampling area centered around 71.487°W and 41.226°N east of Block Island, Rhode Island (USA), yielded estimated neonate dogfish catches ranging from 181 to 2046kg per trawl. Information herein provides the first account of a potential pupping area for this species within its US geographical range.
