Bonefish (Albula vulpes L.) are a highly-prized sportfish. Despite their economic importance, populations in the Florida Keys and Caribbean are in decline with the early life history undescribed. Injections of carp pituitary extract into A. vulpes during advanced stages of ovarian development induced ovulation and spawning. Embryos were sampled hourly until hatching into undeveloped, yolk-sac leptocephalus larvae. These larvae survived until 56 hours post-hatch, when myomeres and eyes were developing, but not the mouth. These results will inform future research on the reproduction and early life history of A. vulpes. This article is protected by copyright. All rights reserved.
