Desarrollo embrionario y estudio morfométrico de la fase lecitotrófica de larvas de medregal negro (Seriola rivoliana Valenciennes, 1883)

Abstract

The present study describes the main embryonic stages and larval development, in culture conditions, of the almaco jack until the fifth day of life. Also a morphometric study of the eggs and larvae from induced spawning was realized. Larval hatching occurred at 36 hours from fertilization. At 60 hours after hatching, 100% of the larvae had their mouths open. At 72 hours all the larvae had a swimming bladder and a digestive tract sufficiently formed to start exogenous feeding.
