Redalyc · Ciencias Marinas
Wild spotted rose snapper, Lutjanus guttatus (n = 400, 60–100 g), were captured and grown out in cages during one year (February 2001 to February 2002). When the mature stage was detected by cannula samples, females (n = 9) were induced to spawn with a total dose of 1600 IU of human chorionic gonado...

When the mature stage was detected by cannula samples, females (n = 9) were induced to spawn with a total dose of 1600 IU of human chorionic gonadotropin (HCG) per kilogram of body weight, given in two injections (56% and 44% of the total dose). Males received only one injection of 200 IU HCG kg–1 body weight, at the time of the second female injection. The sex ratio (female:male) was 1:2. Mean female body weight was 604.9 ± 98.8 g (36.4 ± 2.1 cm). Egg release occurred 9–12 hours after the second injection (latent period), at a temperature of 26.3–28.2oC, salinity of 30–32‰, and oxygen concentration of 5.5–6.6 g L–1. The fertilization rate was 90% of buoyant eggs, with a mean egg diameter of 0.857 ± 0.044 mm. Hatching occurred 15 hours after spawning (h.a.s.) at 26.3–28.2oC. Larvae started feeding 65 h.a.s. and the postflexion stage was observed 27 days after spawning (d.a.s.). The critical period was observed 3–5 d.a.s., as in other lutjanid species. At 26 d.a.s., the growth rate was 0.243 mm d–1 and the survival rate was 1.5%. The growth rate of the fingerlings (171 d.a.s.) was 0.2 g d–1, with a mean body weight of 33.36 ± 9.13 g. Naturally spawned larvae grew until 30 d.a.s., when massive mortality occurred. 2008 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48030191008 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.2 Vol.34 |

Se capturaron y engordaron especimenes silvestres de pargo manchado (n = 400, 60–100 g), Lutjanus guttatus, en jaulas flotantes por un año (de febrero 2001 a febrero 2002). El estado de madurez de las hembras fue registrado mediante muestras de cánula y, cuando se detectó la madurez, las hembras fueron inducidas a desovar con gonadotropina coriónica humana (GCH) en una dosis total de 1600 UI de GCH kg–1 de peso corporal. Las hembras (n = 9) recibieron dos inyecciones (56% y 44% de la dosis total) y los machos fueron inyectados con una dosis de 200 UI de GCH kg–1 de peso corporal, simultáneamente con la segunda inyección de las hembras. La relación de sexos (hembra:macho) fue de 1:2. Los promedios de peso y talla de las hembras fueron de 604.9 ± 98.8 g y 36.4 ± 2.1 cm, respectivamente. El desove ocurrió entre 9 y 12 horas después de la segunda inyección (periodo de latencia) a 30–32‰ de salinidad, 26.3–28.2ºC y 5.5–6.6 g L–1 de oxígeno. El porcentaje de fertilización fue de 90% de los huevos flotantes, cuyos diámetros eran de 0.857 ± 0.044 mm. Las larvas eclosionaron 15 horas después del desove (hdd) a 26.3–28.2ºC . Después de 65 hdd, las larvas empiezan a alimentarse, y 27 días después del desove (ddd) se observó el estado de postflexión. El periodo crítico se detectó, al igual que en otros lutjánidos, entre 3 y 5 ddd. La tasa de crecimiento a los 26 ddd fue de 0.243 mm d–1, y la supervivencia de 1.5%. El crecimiento de los juveniles (171 ddd), con un peso medio de 33.36 ± 9.13 g, fue de 0.2 g d–1. En larvas obtenidas con desove espontáneo, el periodo crítico ocurre a los 30 ddd, cuando se presenta una mortalidad masiva. |
