Control de la reproducción de camarones marinos

Control de la reproducción de camarones marinos

Abstract

El entendimiento de la biología reproductiva básica es necesario para el mejoramiento de la producción de gametos de camarones. Esta presentación revisará nuestro conocimiento actual en materia de determinación sexual, control hormonal de la maduración, fertilización, y técnicas para la producción comercial de gametos y desove. La maduración controlada de camarones es una actividad comercial; sin embargo, no se conoce el modelo genético de los sexos, ni se ha desarrollado la reversión de sexos y producción de monosexos. La fertilización in vitro de Penaeus es aun una técnica de bajos rendimientos, y la criopreservación de embriones o larvas no existe. La ablación ocular continúa siendo la técnica de manejo hormonal para la maduración de hembras, aunque la aplicación de serotonina podría ser una alternativa en el futuro cercano. El avance logrado en producción de espermatóforos y en el entendimiento de los problemas asociados con su calidad, son nuevas contribuciones para el mejoramiento de la reproducción controlada de camarones.

The understanding of basic reproductive biology is necessary for the improvement in the production of shrimp gametes. This presentation will review our current knowledge on subjects like sex determination, hormonal control of maturation, fertilization, and techniques for commercial gamete production and spawning. The controlled reproduction of shrimp is a commercial activity; however, the genetic model for sex determination and sex reversal have not been established. In vitro fertilization and embryo cryopreservation have not been development. Eyestalk ablation is still the only hormonal technique for female maturation, but serotonin treatment could be a new alternative. The advance on spermatophore production and the understanding of the problems involved in its quality are new contributions for the controlled reproduction of shrimp.
