The technology of face recognition fish
Norwegian company Cermaq Group has developed a 3D scanner that can recognize fish on a particular pattern of dots around the eyes and the shape of their mouth and gills.Innovative system called iFarm gives you the opportunity to monitor the status of fish health on salmon farms and to identify the sick animals.
In particular, this technology will be able to prevent the spread of sea lice, which affect hundreds of millions of fish in fish farms and put industry losses of up to $1 billion a year.
“We can create a health card for each particular fish,” said lead researcher Cermaq involved in the system testing of the project iFarm Harald Taco.
It is noted that farming on water and land also decided to use this technology. This year the American company Cargill Inc. said it was working with one of the Irish startup creating a system of facial recognition for cows that allow farmers to better monitor their diets and increase milk production. It is expected that scanners will determine how much food and water consumed by each individual and even days in which cows are ready for insemination.
Following the facial recognition technology will be used on farms for growing salmon. In developed by the iFarm system uses fish cages with a diameter of 160 and a depth of 35 meters, which are used in traditional fish farms.
Innovation iFarms is that inside the enclosed spaces are network cameras to scan the fish. When approximately every four days salmon rise to the surface to gulp air to regulate the swim bladder, the camera scans the entire surface of the fish.
Comparing the image with a database that stores information for each species, the system is able to detect anomalies such as stuck to the body of parasites or sores on the body. Sick fish are carefully removed and placed into quarantine for treatment, and after recovery to return back to the tank.
“The treatment will only send those individuals that really need it. This is usually from 5 to 20% of the total. Thus, do not have to treat and bother healthy fish,” said one of the creators of the program and the head of a startup BioSort the geirr Stang hug.
It is estimated that detection of disease at earlier stages will reduce fish mortality of 50-75 %, which is very important for countries such as Chile and Norway, where in recent years has significantly decreased the population of salmon due to sea lice.
Lice infected fish may not be sold, additionally, the parasite has developed a resistance to the popular chemical drugs. Do non-pesticide treatment methods, like the fast departure of fish in warmer water that kills lice, too, have their shortcomings – they do not protect healthy individuals.
“In most types of aquaculture disease limit the growth of population. If we can take them, we can grow more fish to sell and feed more people,” said the specialist in feeds for fish Cargill Einar Vatne.
