Escala de madurez gonadal del lenguado Paralichthys adspersus (Steindachner, 1867)
Gonadal maturity of fine flounder Paralichthys adspersus (Steindachner, 1867)
Se presenta la escala de madurez gonadal del lenguado Paralichthys adspersus, elaborada en base al análisis y procesamiento histológico de 96 ovarios y 66 testículos de ejemplares capturados en la costa central del Perú y mantenidos en cautiverio. Los ovarios fueron clasificados micro y macroscópicamente, teniendo en cuenta el desarrollo de gametos y gonadas en: virginal, reposo, en maduración, maduro, desovante y recuperación; y a los testículos en virginal, reposo, en maduración, maduro, expulsante y post expulsante. La comparación de las características macro y microscópicas de las
gónadas de peces en cautiverio no mostraron ninguna diferencia con respecto a las gónadas de los peces en su ambiente natural.

ABSTRACT: The scale of gonadal maturity of fine flounder Paralichthys adspersus, made
based on histological analysis and processing 96 ovaries and 66 testes of fish caught in the central coast of
Peru and held in captivity is presented. The ovaries were classified as micro and macroscopically, taking into
account the development of gametes and gonads: inmature, in maturation, mature, spawning, recovery and
inactive; and testes in: Immature, maturing, mature, expulsion, post-expulsion and inactive. Comparison of
macro and microscopic gonads of fish in captivity characteristics showed no difference from the gonads of
fish in their natural environment.
