摘要: Abstract A towed sledge, fitted with television and photographic cameras, was used to observe the behaviour of Nephrops norvegicus in relation tidal currents sea an experimental rig which simulated ground gear component a trawl. Analysis video recordings suggested that, their foraging behaviour, most faced moved downstream. Reaction distances were short 50% touched by before starting swim. The majority Nephrops, initially facing towards approaching gear, reacted it swimming directly away at angle about 90°. This “herding” effect not shown if from gear. In this case animals responded lifting tails back over These observations are discussed commercial trawl
