Attractive effect of acoustic taming on 〖WTHX〗Sparus macrocephalus〖WTHZ〗 in a cage

Abstract:

Fish acoustic taming, as one of the technology in the control of fish behavior, have good promotion in fish control in sea ranching. Among the sound sources, habitat waters background sound of target fish based acoustic taming intends to involve better taming effect. To verify this, habitat waters’ background sound of Sparus macrocephalus is utilized to conduct the acoustic taming in a cage. The results based on the analysis of data and participant experiment observation showed excellent aggregation effect. Acoustic taming on juvenile Sparus macrocephalus needs three stages: acclimatization; impulsion of demanding food (outside sign is that fish reaches certain length and weight); building conditioned reflex between sound and bait. Sparus macrocephalus can identify different sounds and maintain longtime memory. As a strengthening method, offshore background sound based acoustic taming is a valid strategy to make fishes shift from short term memory to long term memory.
