Distant hybridization is a traditional and effective technology in fish genetic breeding. In this study, we reported a new type of golden pompano (Named as Chenhai No.1) produced by the distant hybridization of (Trachinotus ovatus ♀ ​× ​T. blochii ♂) ♀ ​× ​T. ovatus ♂. The results regarding DNA content, chromosomal number, and morphological traits showed that “Chenhai No.1” was a diploid hybrid with 48 chromosomes, and presented a hybrid appearance compared with those in its parents. Meanwhile, all detected “Chenhai No.1” including males and females showed the normal gonadal structure and could produce offspring by self-crossing at 3 years old. In addition, the growth rate of “Chenhai No.1” was 35.52% faster than T. ovatus. In conclusion, the fertile “Chenhai No.1” with faster growth rate provided a superior germplasm resource, which will further promote the industrial development of golden pompano.
