The present invention relates to a trawl (1) for harvesting calanus or other organisms in a body of water. The trawl (1) comprises an outer net (6) and an inner net (8) located inside it, where the inner net (8) is divided up into a number of sections (81, 82, 83). Each section (81, 82, 83) has its own attachment point to the outer net (8), whereby the towing forces are distributed over the different attachment points, with the result that each of the sections (81, 82, 83) absorbs a load. The sections (81, 82, 83) overlap one another by a certain length in such a manner that a front section (81, 82, 83) will extend past and on the inside of the attachment point to a section (82, 83) located at the rear. In addition to better distribution of the towing forces, the independence of the different sections (81, 82, 83) will facilitate repairs and/or replacements of the inner net (8), reduce problems resulting from different lengths between the outer and inner nets (6, 8) during towing of the trawl (1), simplify in
