Abstract

Fenestraja plutonia is an abundant member of the slope community in the western North Atlantic, occurring at depths of 293-1042 m. Aspects of the reproductive biology of F. plutonia were examined for specimens collected off North Carolina, in the summer-fall of 2001, 2002, and 2006. Male-to-female sex ratios were not significantly different from 1:1. The smallest mature male was 215 mm TL, and the smallest mature female was 230 mm TL. Length at 50% maturity was estimated at 231 mm TL for females and 233 mm TL for males, 89 and 90% of maximum TL, respectively. Deposited egg cases (n = 107; six containing embryos), three egg-bearing females, and 11 newly hatched juveniles were collected. It appears that the upper slope off Cape Lookout, NC, at the northern end of the species range, constitutes both an egg-laying area and possibly a nursery area for this species.
