► A new concept combining square and diamond meshes in a 4-panel codend was developed and tested. ► It was found to increase L 50 of Nephrops without increasing discards of either plaice or cod. ► Expected numbers of Nephrops below MLS were reduced by ∼37%. ► Expected weight of marketable catch was...
