| Abstract: | Objective] The aim was to provide basic information for the artificial culture and further research of Coreoperca whiteheadi,and supply scientific theoretical support for the protection of the species resources.Method] The anatomy structure of the digestive system of Coreoperca whiteheadi was observed with naked eyes and under anatomical lens,and the adaptation of its digestive system structure to its diet habits was discussed.Results] The digestive tract of Coreoperca whiteheadi had typical features of carnivorous fish with obvious sections,the fish had big oral fissure with the oral fissure width/length of(1.996±0.811),wide oropharyngeal cavity with the cavity length/body length of(0.943±0.171),and short intestine with intestine length/body length of(0.513±0.061),obvious mucosal rugae had formed in the walls of its esophagus,stomach and intestine.Coreoperca whiteheadi had independent liver and disperse-dense type pancreas.Conclusion] The digestive system structure of Coreoperca whiteheadi adapted to its carnivorous habits. |
