가다 100% 친환경적이고 지속 가능한 – NO MORE CHEMICALS ULTRASOUND IS FISH WELFARE

Aquaculture farmers will save millions

when they understand that ULTRASOUND
controls algae, salmon lice, biofilm and bacteria!
Ultrasound replace expensive and harmful net hosting.

Our test results in Tasmania: 73% reduce of net cleaning.
Algae problem in the fish gills and breathing problems were also solved.

Nothing can compete with ultrasound in fish farming when it comes to solving algae problems.

TEST FOR HUON IN TASMANIA 2022

OUR SALMON FARM TEST IN TASMANIA SHOWS THE DIFFERENCE WITH ALPHA AFTER 8 WEEKS


Some initial results from phase 2:
The control pen reached the net clean trigger score of ‘4’ at 41 days, while the trial net reached the trigger score at day 61 days
(day 59 was not counted as the base score of 4 was confirmed to only be a 3 when checked by net cleaning ROV staff)

The trial pen containing the AlgaeFree ultrasonic units was able to push out the net cleaning interval period to 61 days
compared to the control pen which only achieved 41 days

The net scores for the two pens is included below:

ALPHA reduces net cleaning by 48% and improves fish welfare!

They use ALPHA 4-ways also in smolt plant (Hatchery)

SalMar at Finnsnes in Norway started testing 4 pcs ALPHA 4-ways ultrasound system in their juvenile fishery in 2020.
The result was clear, ultrasound is great for the fish welfare. They observe that after only a few weeks the jellies on the salmon were clean!
That’s why SalMar again in 2020 re-invested in this great system and purchased another 8 ALPHA 4-ways transducers.

Graph from SalMar Test 2019

Test result – Salmar save half the cleaning time with ALPHA 4-ways

SalMar Norway tested from April 2019 to end of the year, 4 pcs ALPHA 4-ways transducers around the salmon fish net
and the result show that they reduce net cleaning by 48%. That means AUD $88,000 savings per cage per year.

HEALTHY SALMON SURVIVE AND GROW FASTER

ALPHA 4-ways in a trickling finger sump in the Hatchery

SalMar at Finses in Norway started testing 4 pcs ALPHA 4-ways ultrasound
system in the trickling finger sump in their hatchery in 2020.
The result was a 100% success for the customer and exceeded their expectations.
They observed that after only a few weeks…
That’s why SalMar in 2020 again invested and purchase 8 pcs ALPHA 4-ways transducers.

ALPHA 2-ways Ultrasound units are used to reduce algae growth and cage fouling in fresh water grow-out ponds.

THIS IS THEIR TRIAL REPORT:

We’ve seen strong results from a recent trial using the small ALPHA 2-ways ultrasound from ALGAEFREE
to reduce algae growth and cage fouling in a fresh water grow-out pond located in the Riverina, 호주.

During the previous season these cages needed cleaning every 2-3 days to maintain water flow and oxygen
levels in the cages. After cleaning each cage the fish would stop feeding for a full day afterwards. This continual
cleaning was contributing to increased labor costs and reduced fish growth.

This season an ALGAEFREE Ultrasound unit was installed in the pond. The cages remained clean for 3 months and were
not cleaned once. The clean cages resulted in reduced labor and increased fish growth with a shorter grow out time.

To validate the performance of the ALGAEFREE ALPHA 2-ways Ultrasound the unit was switched off after running for
3 개월. 10 days later the cages were completely blocked due to fouling and cleaning was required.

One Single ALPHA 2-Ways Ultrasound unit was used for the trial.

is breeding beautiful Cobia fish and they had lots of algae problems in their fresh water pond.

They installed ALPHA 2-ways in 2019 and their Processing Manager Peter Cummings told us that the
result was amazing!That’s why they invested ALPHA 2-ways again in 2020 on different sides of their pond!

BEFORE ALPHA INSTALLATION: Fish net was full of mussel growth

AFTER ALPHA INSTALLATION: There is almost no mussels on the net
