This subject is addressed by modelling data collected during a specially designed experiment.

Instead, a model is required that explicitly considers that not all fish necessarily contact the codend netting to attempt escape during the towing phase. A model that accounts for such behaviour is applied and it is demonstrated that this model can adequately describe the size selection process during towing. The overall escape process, which consists of the attempt probability, partial escape during towing, and partial escape during the haul-back phase, is also modelled. This proposed model sufficiently described the observed escape pattern for cod ( Gadus morhua ), plaice ( Pleuronectes platessa ), and flounder ( Platichtys flesus ).
