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

[EN]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.
