Maturity index validation in the white-spotted skate Bathyraja albomaculata, from the Falkland Islands

Abstract

The reproductive systems of 39 male and 54 female Bathyraja albomaculata were assessed microscopically and compared with macroscopic maturity index values assigned by scientific observers. Inconsistencies were limited to developing maturity stages in both sexes, but such discrepancies were attributed to different factors depending on sex. Furthermore, while spermatozoa were observed in the oviducal gland of females, they do not appear to accommodate long-term sperm storage in this species.
