Algae Control In Aquaculture
For those involved in aquaculture or the farming of fish or shrimp, water quality is all important. Often, due to the shallow nature of many farm ponds, as well as the high concentration of fish kept in them, algae has a prime ground for growth.
Many fish farms now use things like beneficial bacteria to help keep the water cleaner and healthier and along with good aeration these components help to create a better environment for fish rearing.
Algae, and in particular, green water, can still remain a problem despite efforts to control it. It's also been found that controlling planktonic algae with chemicals is not cost effective or neccesarily safe for fish.
Advantages Of Ultrasound In Aquaculture
Fortunately ultrasound technology is proving to be very effective and safe when used in aquaculture.
Several studies in Europe have proven that ultrasound works very well on reducing green water problems, but it also seems to raise oxygen levels in the pond slightly as well.
The die off of algae tends to be very gradual which makes it much safer when guarding against oxygen depletion in the water.
Perhaps due to increased water clarity, where they could find food more easily, fish in the ultrasonic treated pond gained more weight in a side by side test with an untreated pond.
Pond cleaning is another element of aquaculture that isn't always pleasant but necessary. In the studies, it was found that for ponds treated with ultrasound, biofilm formation was limited, making the routine cleaning less frequent, and much easier when it had to be done.
All the while, fish and other aquatic life remained unaffected by the ultrasonic waves. Since the frequency range of the devices is very targeted to algae types, ultrasound is proving to be a very safe and effective pond algae control in a number of applications.
