Approximately 2.4 million tonnes of salmon is farmed each year
currently, with about a third of this aquaculture in Norway. It is
no surprise, then, that this is driving Norwegian technology
firms to develop hi-tech solutions to improve the efficiency of
fish farming.
How do you know if fish have eaten all their food or are still
hungry? Cage
Eye uses a hydro-acoustic system that listens to the
noise of the fish feeding and so can tell when they have had
enough. This helps to optimise the amount of food used to feed the
fish, so little food is wasted. The system can also be used with
artificial intelligent systems to learn the feeding patterns of the
fish.
How do you treat fish effectively to eradicate parasitic sea
lice? Stingray uses a laser system to identify
and then destroy the lice, without harming the fish. This helps to
reduce the number of fish that are damaged by lice and cannot be
sold for consumption.
