AI Technical Summary
Traditional cage aquaculture is prone to damage, increases labor intensity and costs, affects the exercise and meat quality of large yellow croaker, and pollutes the marine environment.
A sound wave enclosure device for large yellow croaker farming based on a funnel-shaped mouth is adopted. A directional sound curtain is formed by a low-frequency underwater emission array and a directional funnel-shaped mouth structure. The sound sensitivity of the large yellow croaker is used for enclosure and control, reducing the sound energy diffusion in non-target areas.
It improved the effectiveness of acoustic containment, reduced system costs, protected the marine ecosystem, increased the activity level and meat quality of large yellow croaker, and reduced the frequency of escape and cleanup.
