A catchment net (1), especially for rockfall blocking, includes a net (2) consisting of elements that engage with each other, and whose two longitudinal sides are each moveably held by a holding rope (3, 4) extending between at least two support bodies (7, 8, 9, 10). The two holding ropes (3, 4) are moveably held by the individual support bodies (7, 8, 9, 10) in their longitudinal direction and tensioned at the side. At least one running rope (37, 38, 39, 40; 47, 48, 49, 50) or suchlike extending alongside the support body on each of the holding ropes (3, 4) preferably within the area of the each support body (7, 8, 9, 10) is affixed with one end on one side and with the other end on the other side to the support body (7, 8, 9, 10). The net (2) is moveably held within the support body area by the running ropes (37, 38, 39, 40; 47, 48, 49, 50). The catchment net (1) therefore guarantees an optimal load distribution as well as a more favorable flow of energy through the net.
