“…In the most economically important penaeid species: the white shrimp Litopenaeus vannamei , the complete sequence of the IAG gene was recently reported (Vázquez‐Islas, Garza‐Torres, Guerrero‐Tortolero & Campos‐Ramos ). The histology of the presumptive AG of Litopenaeus , including the southern shrimp Litopenaeus setiferus, the white shrimp Litopenaeus occidentalis, the blue shrimp Litopenaeus stylirostris and L. vannamei has been partially described (Campos‐Ramos, Garza‐Torres, Guerrero‐Tortolero, Maeda‐Martínez & Obregón‐Barboza ; Garza‐Torres, Campos‐Ramos & Maeda‐Martínez ; Alfaro‐Montoya & Hernández ; Vázquez‐Islas et al . ).…”

This research was implemented to study the effects of androgenic gland ablation in the white shrimp Litopenaeus vannamei to explore sex reversal potential as an alternative technology for monosex female mariculture based on the sex dimorphic growth of this species. The surgical procedure was applied to male postlarvae (PL) at different ages, after external sex differentiation, as well as in sex undifferentiated PL. Andrectomized males regenerated normal appendices including pereiopods and pleopods; however, body growth and relative size of regenerated petasmas and appendices masculinae were statistically inferior (P ˂ 0.05) to control males. Spermatogenesis in andrectomized males was active, but a phenomenon of degradation of spermatids and reproductive tissues was detected. No sex reversal was accomplished regardless of PL age from sex undifferentiated stages (PL38) to sex differentiated stages (˃PL55). The complete regeneration of sexual characters in andrectomized L. vannamei (Dendrobranchiata) is different from previous reports from Decapoda.

“…Esta investigación mejoró el conocimiento de la organización general del sistema reproductivo de machos de Litopenaeus y Rimapenaeus y aportó una base anatómica para la manipulación de la glándula androgénica (Alfaro-Montoya & Hernández, 2012). Las primeras observaciones de la ultraestructura de la glándula androgénica en camarones peneidos fueron realizadas por Alfaro-Montoya (1994).…”

El desarrollo de la maricultura en Costa Rica ha requerido de la validación, la innovación y la generación de conocimiento científico biotecnológico. Se presenta una revisión de los principales avances biotecnológicos sobre maricultura que han sido aplicados y desarrollados por la Escuela de Ciencias Biológicas de la Universidad Nacional de Costa Rica. La experimentación y optimización de la tecnología del cultivo de Crassostrea gigas ha impulsado la ostricultura en el país y el surgimiento de emprendimientos locales. La investigación científica realizada ha generado avances biotecnológicos de relevancia mundial sobre la biología reproductiva de camarones peneidos y ha permitido la reproducción controlada de peces marinos de interés comercial del Golfo de Nicoya, Costa Rica. Además, se han aplicado y evaluado técnicas biotecnológicas para el cultivo de microalgas, depuración bacteriana de moluscos, vigilancia de Floraciones Algales Nocivas y biorremediación. Se debe fortalecer la investigación biotecnológica sobre maricultura, fomentar la transferencia de la biotecnología desarrollada y promover la protección por medio de la propiedad intelectual de la innovación biotecnológica generada como herramientas para el desarrollo económico y social en Costa Rica.
