Comparative Analysis of Embryonic Development and Mitochondrial Genome of a New Intergeneric Hybrid Grouper (<i>Epinephelus fasciatus</i> ♀ × <i>Plectropomus leopardus</i> ♂).

ABSTRACT: To develop superior grouper aquaculture varieties, in this study, a intergeneric hybrid breed was constructed by crossing a male Plectropomus leopardus, with a female parent Epinephelus fasciatus. Here, we researched embryonic development and mitochondrial composition of the new hybrid germplasm. Results revealed that the fertilization and hatching rate were 85.87 ± 5.22% and 70.37 ± 0.33%, respectively. Hatching occurred 28 h 55 min after fertilization at 24.8 ± 0.5 °C, and the newly hatched larvae were 2.05 ± 0.37 mm in total length. The mitochondrial genome length of the hybrid was 16,570 bp, preserving 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, and 22 transfer RNA (tRNA) genes. The mitochondrial gene composition and arrangement of the hybrid were very
