ABSTRACT: Golden pompano Trachinotus ovatus (Linnaeus, 1758) is an important mariculture fish species with high commercial value in China. The present study thoroughly assessed the types and frequencies of skeletal deformities at the early developmental stages of golden pompano in an intensive aquaculture production system. Golden pompano (n = 500) were sampled 30 d posthatch (dph). The specimens were stained with Alcian blue and Alizarin red for the detection of deformities. The results of the study revealed that 77.2% of the specimens showed at least 1 spinal anomaly; most anomalies occurred in the prehemal region, and the most common deformity observed was vertebral fusion (37.4% incidence of deformities). The results of this study provide useful information for the early detection of skeletal deformities and for the optimization of fish fry breeding technologies.
