| Sumario: | The goal of this study was to determine the effect of the liquid extract of Yucca schidigera on water quality and survival of Pacific red snapper Lutjanus peru during its transfer from wild to laboratory conditions. Three experimental groups (0.00; 0.25 and 0.75 mg of Y. schidigera liquid extract per liter of culture) were tested with four replicates using water recirculating systems. The liquid extract was dispensed every 72 h during 28 days. It was proved that Y. schidigera extract could be effective to reduce ammonia nitrogen caused by biogenic source (excretion of fish juveniles) diminishing mortality of Pacific red snapper during acclimatization process. It is recommended the use of yucca extract concentration at a dose of 0.75 mg L-1 to reduce ammonia concentration in marine water for holding red snapper juveniles. |
