Abstract
Deformity during the early development of golden pompano Trachinotus ovatus has significantly influenced the production capacity of a fish hatchery. However, factors leading to skeletal deformity in this species have never been assessed. In this chapter, the impact of rearing temperature on jaw deformity and BMP gene expression is discussed. Jaw deformity rate of fish larvae increased with the increase of ambient temperature, and the highest malformation rate was recorded at 33 °C. The expressions of the BMP4 and BMP5 genes were positively correlated to the occurrence of jaw malformation. The cultivating water temperature of T. ovatus larvae should be maintained at 26–29 °C. These findings will clarify the role of water temperature in influencing bone deformity in fish larvae and provide a reference point to optimize the environmental condition during the rearing process of golden pompano in hatcheries.
