Ocea Bremnes Seashore double team on sea lice solution22 April, 2014 –
OCEA and Bremnes Seashore recently signed an agreement on the further development of the Ocea Thermolicer.
At the same time the parties also signed a contract for a new 400-tonne feed barge and various other products to a total value of NOK 28 million.
Ocea Chile has for already supplied the Chilean market with delousing services for a select group of costumers, the method is now ready to be scaled to Norwegian conditions, says Karl Petter Myklebust of Ocea.
We have had very good delousing results; we have also had low mortality rates 3 days after treatments, and after 60 days.
In collaboration with Bremnes, we plan to further develop the process, focusing on animal welfare and increased capacity.
We have also engaged the Norwegian veterinary institute to ensure third party documentation of the method in Norway.
The first commercial Thermolicer is already being built, and we will test the machine together with Bremnes this autumn.
We at Bremnes Seashore are excited about the Thermolicer, says Geir Magne Knutsen, Head of farming at Bremnes Seashore.
We want early access to the machine to ensure that we have the right tools in our toolkit. Resistance towards treatments is an increasing issue, and we want to participate in the development of the tools of the future.
We are amongst other things working with cleaner fish to keep the number of lice as low as possible, but when we need to actively delouse the fish, we will use the Thermolicer, starting this autumn.
The results from Chile are very promising. It is also an important factor that the method is not using any chemicals harmful to the environment in our fjords.
Together with Ocea, we will use the next months to test the Thermolicer; this will provide us with important experience so that we can be fully prepared for when the delousing period starts.
Karl Petter Myklebust of Ocea, explains that they are working with a select group of customers about delivering a few additional Thermolicers. The industry is clearly very interested in our patented Thermolicer; we have had inquiries from a number of farmers in Norway and abroad.
We know that the machine and the method does work, but we want a controlled approach to the Norwegian conditions. The handling of fish is something we take seriously, and we are going to ensure that the machine and method is as gentle as possible, while also increasing capacity.
Ocea has been working on a thermic delouser since 2007. The start of the project was a lucky coincidence.
Ocea was working on the use of low voltage as a delousing method, an observed that the lice seemed to die instantly when cleaning some tubs used for tests with lukewarm water.
This started a 7-year development process and resulted in a patented method commercialised in Chile.
The Thermolicer is about to be commercialised in Norway and the North Sea area. In Chile the machine has produced very good delousing results, and proved to be gentle on the fish.
The fish is pumped into a lukewarm bath that last about 30 seconds. The lice die from the sudden temperature change, and the fish is pumped back to the cage lice-free. The lice are collected and destroyed.
