<p>The invention relates to a fishing protector (2) and a method for use of the fishing protector at or near the sea bed by long-line fishing to avoid that the catch is eaten by sea mammal when the line (3) with the catch is hauled into a fishing boat. A gliding stopper (6) is fastened at the termination of the line (3) and thereafter the fishing protector (2) is hooked on the line during the setting out of the line such that the line (3) passes through the fishing protector (2). By hauling of the line (3) the line is passing through the fishing protector (2) and the catch is hooked off inside the fishing protector (2). An opening and closing mechanism (11) at a first termination (12) of the fishing protector closes the opening (9) through which the fish passed, avoiding fish to escape. Finally, the opening (9) for receiving fish in the fishing protector (2) is closed by a gliding stopper (6) before the fishing protector (2) is hauled towards the surface.</p>
