A snag-free and stress-free fish catcher includes a supporting frame, a fish pocket, having a fish cavity, supported by the supporting frame, and a tension resting bed, having a tension surface, supported within the fish cavity, wherein the tension surface of the tension resting bed has a predetermined tension larger than a weight of the fish. Therefore, when the fish is captured within the fish cavity of the fish pocket, the fish lies on the tension surface of the tension resting bed in a flatten manner.
