Is human digestive system the same with the fish?

No, the human digestive system is not the same as that of fish. Humans have a more complex digestive system with specialized organs like the stomach, small intestine, and large intestine, designed for a varied diet that includes both plant and animal matter. Fish, on the other hand, typically have a simpler digestive system that is adapted for their aquatic environment and primarily consists of a straight gut with a stomach and a shorter intestine, suited for digesting primarily protein-rich diets. Additionally, fish often rely on different mechanisms for digestion, such as the use of enzymes that operate in a cooler environment.
