“…Fish, particularly carnivorous ones, have a lower capacity to utilize carbohydrates in comparison to mammals. When digestible carbohydrate levels exceed 20% to 30% of the diet, these fish suffer from prolonged postprandial glycemia ( Kamalam et al., 2017 ; Steinberg et al., 2022 ) and growth impairment ( Volkoff and London, 2018 ). As a result, the study of glucose metabolic homeostasis and utilization mechanisms in fish, particularly carnivorous fish, has received considerable attention.…”
