| Resumen : | An experiment was designed totally randomized to study the influence of
different rate of Na+/K+ (5, 30, 55, 70, 95 and 120). Massive mortality was
presented to the sixth day of the treatments I and III (Na+/K+=5 and
Na+/K+=120), to the seventh day the treatment V (Na+/K+=95) and to the
eighth day of the treatment IV (Na+/K+=70). The treatments II and III
(Na+/K+=30 and Na+/K+=55 respectively) they stayed in the time, when
indicating a bigger tolerance of the postlarvae in these ranges of Na+/K+;
however, the mortality of the treatment II were significantly bigger (p <0.01) that
in the treatment III, in which 90-100% survival was observed. The results
indicate a better physiologic answer of L. vannamei postlarvae to relationships
Na+/K+ among 8-48, with a good of 30-32, that which has implications for the
handling and preparation, of the water of culture of low salinity (up to 2 ups)
during the nursery phase and growth out. |
