  Foto: Larvas vitelinas de huayaipe (Seriola rivoliana) en la acuicultura marina del Ecuador. Fotografías del III PhotoFIRMA

  Descripción: La obtención de larvas vitelinas de buena calidad en cautiverio es parte del éxito de la producción controlada del huayaipe. Seriola rivoliana es una especie potencial para la acuicultura ecuatoriana gracias a sus características ventajosas como buena calidad de la carne, fácil adaptabilidad a cautiverio, rápido crecimiento y alto valor comercial. El huayaipe es una especie gonocórica que desova espontáneamente en cautiverio de forma parcial. El fruto de varios años de investigación ha permitido la obtención continua de desoves viables de esta especie bajo condiciones controladas en el laboratorio de Piscicultura del Centro Nacional de Acuicultura e Investigaciones Marinas (CENAIM-ESPOL). Este es un paso más hacia el desarrollo de la maricultura en el país.  Esta fotografía fue tomada el 17 de mayo del 2018 en un microscopio óptico (4x) en el laboratorio de Piscicultura de CENAIM-ESPOL, tras la obtención de un desove viable seleccionado para la fase de larvicultura.
