description Many species in the family Serranidae are hermaphrodites and of commercial importance. Paranthias colonus belongs to this family, and its reproductive traits are unknown. The present research was carried out with specimens taken from the commercial fishery on the southern coast of Jalisco, Mexico. A total of 1,541 specimens were processed, with an average length of 30.30 ± 0.10 cm and a length interval of 19.80 to 38.00 cm. Specimen gonads were analyzed macro- and microscopically. The sex ratio was 1.00:0.97 (F:M). According to the maximum monthly values of the gonadosomatic index, gonad maturity stages, and oocyte diameters, P. colonus has 2 broad reproductive periods, from March to June and from November to December. A significant correlation was found between the monthly mean values of the gonadosomatic index and the relative condition factor. Gonads in the mature stage had oocytes in 6 different development phases, with diameters that ranged from 14.30 to 417.40 µm, which means that oocyte development is asynchronous. In the testicle, the development of the germ line is of the unrestricted lobular type. This organ did not present the typical arrangement found in teleost fish, since lobes seem to be delimited by lamellae. The information developed in this study indicates that P. colonus is a gonochoric species. Average length at sexual maturity was 26.80 cm for females and 26.90 cm for males. Average catch lengths indicated that 79.70% of females and 83.30% of males had already reproduced at least once before being caught.

Muchas especies de la familia Serranidae son hermafroditas y tienen importancia comercial. Paranthias colonus pertenece a esta familia, y no se conocen las características de su reproducción. La presente investigación se llevó a cabo con ejemplares provenientes de la pesca comercial en la costa sur de Jalisco, México. En total, fueron procesados 1,541 ejemplares, los cuales presentaron una longitud media de 30.30 ± 0.10 cm y un intervalo de longitud de 19.80 a 38.00 cm. Las gónadas de los ejemplares fueron analizadas macro y microscópicamente. La proporción de sexos fue de 1.00:0.97 (H:M). De acuerdo con los valores mensuales máximos del índice gonadosomático, los estadios de madurez gonadal y el diámetro de los ovocitos, P. colonus presenta 2 periodos reproductivos amplios, de marzo a junio y de noviembre a diciembre. Se encontró correlación significativa entre los valores medios mensuales del índice gonadosomático y el factor de condición relativo. Las gónadas en estadio maduro presentaron ovocitos en 6 fases de desarrollo diferentes y con diámetros de 14.30 a 417.40 µm, lo que supone que el desarrollo de los ovocitos es asincrónico. En el testículo, el desarrollo de la línea germinal es del tipo lobular no restringido. Este órgano no presentó un arreglo típico de un pez teleósteo, ya que los lóbulos parecen estar delimitados por lamelas. La información generada en este estudio indica que P. colonus es una especie gonocórica. La longitud media de madurez fue de 26.80 cm en hembras y 26.90 cm en machos. Las longitudes medias de captura indicaron que el 79.70% de las hembras y el 83.30% de los machos ya se habían reproducido por lo menos una vez antes de ser capturados.
