Advances in spotted rose snapper (Lutjanus guttatus, steindAchner, 1869) juveniles production
This study describes the advances in spotted rose snapper Lutjanus guttatus juveniles production. The broodstock (three groups, each of ten females, mean ± SD: 0.91 ± 0.2 kg and 20 males 1.2 ± 0.3 kg) with two years, were acclimated for 1.5 years in three communal cylindrical fiberglass tanks (18-m3). Fertilized eggs were obtained during natural spawning seasons. Floating eggs (average 90 ± 2%) were collected be- tween 12 to 14 h after spawning. An average of 97% of them were trans- parent with live embryos. For the larval rearing process, initial stock- ing densities were 196 ± 70 embryos/l, incubated in twelve 6-m3 cylin- drical fiberglass tanks with 3-m3 of water. The incubation period was 20 h at 26-28 °C. Hatching and survival at 48-h post-hatch (hph) were 90 ± 2% and 55 ± 10%, respectively, with an average of 281,258± 92,202 48-h larvae per tank and 105 ± 33 larvae/l at first feeding. A total of 338,812 juveniles with 45 days post-hatched (dph) were harvested, at an aver- age of 28,234 ± 11,890 per larval rearing tank (2.4±1.0/l), and 180,000 juveniles (BW: Body weight of 5-8 g) from the nursery tanks with 90 dph. Average survival from first feeding to end of 45 dph rearing period was 12 ± 9%. The average harvest weight was 0.47 ± 0.10 g BW and the average final biomass per larval tank was 13 kg. An efficiency index at 45 days culture was 10 / 48-h larvae/juvenile, while at 90 dph the efficiency index was 19 / 48-h larvae/juvenile. The result showed that changes to the previous culture protocols of the CIAD-Mazatlan fish plant, ensure a higher production of juveniles.

El presente estudio describe los avances en la producción de juveniles del pargo flamenco Lutjanus guttatus. Los reproductores (tres grupos, cada uno de 10 hembras, media ± SD: 0.91± 0.2 kg y 20 machos 1.2 ± 0.3 kg) con dos años, fueron aclimatados por 1.5 años en tres tanques comunales cilíndricos de fibra de vi- drio (18-m3). Los huevos fertilizados fueron obtenidos durante las temporadas naturales de desove. Los huevos flotantes (promedio de 90 ± 2%) se colectaron entre 12 a 14 horas post-desove. En promedio, el 97% de ellos fue- ron transparentes, con un embrión vivo. La densidad inicial de siembra para la cría larval fue de 196 ± 70 embriones/l, incubados en doce tanques cilíndricos de 6-m3 con 3-m3 de agua. El periodo de incubación fue de 20 h a 26-28°C. Los porcentajes de eclosión y de supervi- vencia a las 48 horas posteclosión (hpe) fueron 90 ± 2% y 55 ± 10%, respectivamente, con un promedio de larvas de 48-hpe de 281,258 ± 92,202 por tanque y 105 ± 33/l. Se cosechó un total de 338,812 juveniles con 45 días des- pués de la eclosión (dpe) a una densidad pro- medio de 28,234 ± 11,890 por tanque (2.4 ± 1.0/l). En el alevinaje se cosecharon 180,000 juveniles de 90 dpe (peso del cuerpo: 5-8 g). La supervivencia desde la primera alimentación hasta los 45 dpe fue de 12 ± 9 %, con un peso medio de 0.47 ± 0.10 g y una biomasa final por tanque de 13 kg. El índice de eficiencia a los 45 días de cría fue de 10 larvas de 48 hpe por juvenil producido, mientras que a los 90 dpe el índice fue de 19 larvas de 48 hpe por juvenil producido. Los resultados mostraron que los cambios a los previos protocolos de cultivo de la planta de peces CIAD-Mazatlán, aseguran una mayor producción de juveniles.
