Invention allowing fish to be measured with the aid of a gauge, whatever the orientation of the fish in the gauge without the fisherman having to touch the fish either to measure it or to remove the hook. It consists of a gutter having two end stops A and which serves as an orifice with two graduations C and D. The gauge is fixed to the bottom of the netting part of a landing net by the use of holes F. The measurement of the fish is done by bringing the nose of the fish to one end stop and by reading its length on the graduation. By clamping the fish between the gauge and the netting of the landing net, it is possible to remove the hook. <IMAGE>
