Salmon farming industry uses ultrasonic technology to control harmful algae

The salmon farming industry uses ultrasonic technology to control harmful algae. The ultrasound test results show that under laboratory conditions, ultrasound is an effective solution to reduce algae. The combination of low power (below 10 kW/m ²) and long action time (more than 1 minute) is an efficient solution for treating harmful algae on a commercial scale. The ultrasonic algae control system includes complex monitoring equipment that can provide a comprehensive understanding of water quality and provide a basis for using ultrasonic waves to control algae.

Real time monitoring of major water quality indicators (dissolved oxygen and temperature) and algal indicators (chlorophyll-a and phycocyanin) can be used to predict algal blooms. Early detection of harmful algal blooms is crucial as it allows breeders time to make important decisions and minimize losses. The application of ultrasound in marine environments, especially in salmon farming, can reduce harmful algae, whose toxins can lead to massive salmon mortality.
