Abstract
Device, system and method for distribution of pesticides to reduce or eliminate parasitic creatures liable to infest aquaculture facilities or the animals kept in these, such as salmon lice in a fish farm. The invention is based on the use of pesticides at a concentration level low enough to not represent a dangerous level for the environment, but for a longer exposure period, sufficient to enable delousing to occur.
Claims18
A distribution device for treating a fluid, comprising:
- a pesticide,
- a body comprising a base for carrying the pesticide,
- wherein the pesticide is able to be excreted into a volume of fluid when the body is brought in contact with the fluid,
- one or more protrusions for increasing an area of the device and thereby a contact area between the base for carrying the pesticide and the fluid in which it is released, and
- a sensor arrangement configured to determine a level of pesticide concentration in the fluid outside the device.
