Why use a freshwater depot? 

Sea lice are sensitive to sea water and typically do not survive in very low salinity water. Using freshwater treatments encourages the sea lice to detach from its salmonid host resulting in the parasite being removed from the system. The freshwater depot eradicates the need for well boat access and provides a continual supply of freshwater on site. 

When it comes to the use of fresh water to treat fish for AGD results have shown that FW was more effective than hydrogen peroxide in addition to being less harmful for the fish gills.  

With a freshwater depot you can save time and money. For example, a wellboat will use 1.5 hours to fill 1800 m³ from a freshwater source before transiting to site to treat the fish. In the freshwater depot, there is enough water in one Ø = 120m depot to fill three wellboats with 1800 m³ which is already on site and ready to use.
