ABSTRACT:
Improvements on the Parra "METHOD AND APPARATUS FOR SEPARATING DOLPHIN FROM TUNA" using the primordial fear of dolphin of killer whales to separate dolphin from tuna wherein the sound of feeding killer whale is recorded, digitized, edited and enhanced to produce digitally synthesized killer whale sounds. These digitally synthesized sounds of one or more feeding killer whale is played under water and in the vicinity of a mixed school of dolphin and tuna and as the dolphin leave said vicinity, catching the tuna in nets. According to the present invention, one or more of a plurality of playback units are selectively triggered on and off from a remote location to steer the dolphin to safety. The playback unit is carried in an elongated hollow tube having a weighted end and a recovery end, the weight causing the end it is on to go to a predetermined depth in the sea with the recovery end having a hook for aerial retrieval. In one embodiment, the playback unit is in the form of a killer whale sonic grenade and a pressure sensor senses a predetermined depth and activates the playback unit.
