Article: Determining the safety range of electrical pulses for two benthic invertebrates: brown shrimp (Crangon crangon L.) and ragworm (Alitta virens S.)Target catch: Shrimp tended to do a tail flip in response to some electric pulses and ragworm showed a squirming response independent of the frequency. Study Type: Study in the labEffect on target catch: N/AEffect on bycatch species: N/ABycatch species: InvertebratesReduction technique: Electromagnetic deterrents
