Bile acids in fish, as in other vertebrates, represent a complex metabolic system the composition of which depends on species, age, diet, and environmental conditions. Their ratio is closely associated with enterohepatic circulation—a continuous cycle of bile acid synthesis, transport, utilization, and reabsorption that maintains their optimal concentration in the body. This process involves the liver, bile ducts, gallbladder, and intestine. Disruptions of enterohepatic circulation caused by imp
