A bucket using a box-like parallel-sided basket open at the front for dredging the sea bottom to collect nodules. The basket has a bottom wall with front and rear cross-bars and a plurality of parallel spaced rods extending longitudinally of the basket between the front and rear cross-bars. A front part of the bottom wall includes a grill formed by a transverse front link supporting one end of a plurality of longitudinal spaced flexible elements which are inclined downwardly towards the front and stretched between the front cross-bar and the transverse front link. Large shoes are positioned on lateral sides of the basket for supporting the bucket on the sea bottom. The grill is situated between the shoes with the transverse front link positioned in such manner that it penetrates the sea bottom. The basket is positioned inside the shoes and extends to the external edges of the shoes. The shoes include brackets for connecting a dredging line to the bucket.
