Apparatus for measuring tensile forces in the cables joining fishing nets to the trawler, comprising at least three guide rollers 2, 3, 4 for the cable 15, in which at least one central recording roller 4 is connected to a force sensor element 16 for recording the radial thrust on this central roller 4, characterised in that the relative position of the rollers is such that the cable 15 can pass over the same sides as the rollers 2, 3, 4, and that an angle of deflection alpha is obtained in the cable in line with the central recording roller 4. <IMAGE>
