摘要：

Alepocephalus bairdii is a deep sea fish caught but discarded by semi-industrial fisheries from the north-east Atlantic Ocean. Reproductive features were investigated on 448 females of 29-93 cm standard length (SL) captured over 2 y (December 1995 December 1997) at 800-1280 m off the west coast of the British Isles. The first maturity of females was determined at L-50=55 cm SL. A well-defined spawning period could not be determined in this species; a batch spawner characterized by an indeterminate annual fecundity. Absolute batch fecundity was estimated between 458 and 7049 oocytes per female 63-88 cm SL.
