Escape, discard and landing probability of Nephrops norvegicus in the Mediterranean Sea creel fishery
Mašanović, Marina; Herrmann, Bent; Brčić, Jure (Peer reviewed; Journal article, 2022)Size selection in creel fishery consists of two processes: the first taking place in the creel on the seabed and the second made by the fisher on the vessel. However, no study has ever considered both processes when assessing ... -
