摘要: Golden pompano Trachinotus ovatus larvae were reared at 23, 26, 29 and 33 degrees C from 3 day post-hatching (DPH) to 18 DPH. Growth, survival, RNA/DNA ratio, as well as jaw and skeleton deformities were used as evaluation criteria on fish performance. Growth of fish held at 29 and 33 degrees C was significantly faster than those held at 23 and 26 degrees C, while survival at 26 and 29 degrees C was higher than those held at 23 and 33 degrees C. Similarly, the RNA/DNA ratio was higher at 26 and 29 degrees C than at 33 degrees C. Jaw deformities significantly increased when the rearing temperature exceeded 29 degrees C, while vertebral deformities were encountered more frequently at 33 degrees C than at lower temperatures. Results of the study indicate that the temperature range of 26 to 29 degrees C is appropriate while temperatures >33 degrees C or <23 degrees C can have adverse impact on rearing of golden pompano larvae.
