Description
Summary:We provide a scientific basis for recommending commercial encounter protocols for sponges and sea pens in the NRA. For each we provide an assessment of significant adverse impact of bottom trawling taking into account published and new data on gear efficiency and selectivity, incidental mortality and recoverability. The proportion of VMS trawls in 2010 that would be impacted by lowering the current thresholds is estimated following previously established methods. Approaches to move-on rules are also considered.
