  1. Reduce duration of fishing gear deployments

    A replicated, controlled study in 2014–2015 on an area of seabed in the southern North Sea, Netherlands and UK (van der Reijden et al. 2017) found that reducing the length of the hauls using a pulse trawl increased survival of plaice Pleuronectes platessa compared to standard length hauls, over haul durations of 60–130 minutes. When haul duration was 60–70 minutes, more plaice survived compared to standard 100–130 minute hauls (data not reported). Two fishing vessels were used to carry out three surveys with two short (60–70 minute) hauls and four surveys with standard (100–130 minute) hauls using standard fishing operations with a pulse trawl, between November 2014 and September 2015. After sorting the catch on deck, 40 fish below commercial size from each haul were kept in seawater tanks and fed every 24 hours. Survival was monitored daily for at least 21 days.
