Short Communication Fecundity of Northeast Atlantic spurdog (Squalus acanthias)

sample of 202 of these fish (82–117-cm total length, L) indicated that 28 % were carrying near-term pups, 70 % year one pups, and 1% candles. Uterine fecundity (F) for those fish that were not considered to have aborted pups (n 179) ranged from 3 to 21 and increased with total length, where F 0.428...

Description
Summary:sample of 202 of these fish (82–117-cm total length, L) indicated that 28 % were carrying near-term pups, 70 % year one pups, and 1% candles. Uterine fecundity (F) for those fish that were not considered to have aborted pups (n 179) ranged from 3 to 21 and increased with total length, where F 0.428 L231.87. The upper limits of these fecundity estimates are the highest recorded for spurdog in the Northeast Atlantic. These data are discussed in relation to previously published fecundity estimates and the possibility of a density-dependent increase in fecundity.
