Much of this work has focussed on modifications at, or near, the codend (at the aft section) of trawls,...

The project outputs have led to the following outcomes: 1. A model has been developed enabling reliable estimation of mortality of fish species that undertake size-related, unidirectional, offshore movements from age and length data. This new modelling approach is likely to be applicable to stocks...
