Supporting evidence from individual studies
A repeated, randomised and controlled trial in a drift gillnet fishery in North Puget Sound, Washington, USA, in July and August 1996 (Melvin et al. 1999), found that nets fitted with acoustic alerts (‘pingers’) caught significantly fewer common guillemots (common murres) Uria aalge than control nets (0.31 vs. 0.60 entanglements/net). There was no significant change in the number of rhinoceros auklets Cerorhinca monocerata caught. A total of eight boats and 321 net sets were studied.
