Estudios preliminares para la determinación del sexo y evolución de la madurez del ovario en el lenguado senegalés (Solea senegalensis) utilizando técnicas de ultrasonido.

Abstract

In this work, the use of the ultrasound technique to determine the sex and maturity stage of Senegalese sole (Solea senegalensis) is described. This technique, already used with other species, can help to improve the knowledge on sole reproduction. Once the maturity stage is determined, individuals can undergo spawning induction by physical or hormonal methods, avoiding more aggressive methods such as the intraovaric cannulation. Using an ultrasound scanner HONDA HS-2000, we were able to observe the position of organs such as liver, gallbladder, heart and gonads. In the case of gonads, apart from clearly distinguishing between males and females, it is possible to observe the different maturity stages of females and the testicles size.
