摘要： Golden pompano Trachinotus ovatus larvae were kept at 26, 29 and 33 degrees C for 15 days from 3-day post hatching (DPH) to 18 DPH to test temperature-dependent growth and jaw malformation. The growth, survival, jaw deformity and the gene expressions of bone morphogenetic proteins (BMPs) were used as criteria to examine the fish response to temperature manipulation. The growth rate of fish at 29 or 33 degrees C was significantly faster than fish at 26 degrees C, while fish survival at 29 degrees C was significantly higher than fish at 33 degrees C. Jaw deformity was significantly affected by water temperature. The highest jaw deformity occurred on fish at 33 degrees C, and the lowest jaw deformity was at 26 degrees C. The expressions of all BMP genes except BMP10 were significantly affected by water temperature. The highest gene expression of BMP2 was on fish at 29 degrees C, and the lowest expression was at 33 degrees C. For the BMP4 gene, the highest and lowest expressions were found on fish at 33 and 26 degrees C, respectively. The present study indicates that jaw deformity of golden pompano larvae increases with increasing temperature, and the gene expression of BMP4 proteins coincides with high jaw deformity and water temperature elevation.
