20 Environment aquaculture, if properly managed, can provide the world with healthy, protein-rich food with less impact on the environment than traditional agriculture. With the right measures, we can minimize or even eliminate certain risks to the environment. Salmon production, along with any other food industry, involves environmental concerns that we work hard to diminish. Caring for nature and protecting our assets are parallelagendas on which Grieg Seafood spends considerable resources. Hire a custodian parasite problems are not exclusive to fsh farming. internal and external parasites are plagues within the cattle, sheep, pork and poultry industries. The standard treatment for parasites is to use pharmaceuticals, but in aquaculture there are natural alternatives that prove more effcient. One technique to lessen the use of pharmaceuticals in the marine environment and still control an outbreak of salmon lice is to introduce different types of wrasses into the nets. Wrasses are fsh that feed on ectoparasites. These “custodians of the waters” have shown to be very effcient, clearing a lice infection before it does much harm. This is an environmentally rewarding alternative to pharmaceuticals. Location, location, location The real-estate mantra is just as relevant in fsh farming. Ensuring that fsh farms have an adequate current with clean, oxygen-rich seawater to handle excrement and surplus feed is another method The highest percentage of fsh escape because of poor weather to lessen environmental impact. Grieg Seafood farms are in deep conditions. Bad weather, however, is not an acceptable excuse areas with good water replacement, where discharge is handled for Grieg Seafood. Taking extraordinary steps to ensure that our well within the limits of the surrounding ecosystem. assets are well-protected against natural forces, Grieg Seafood has developed a zero-tolerance stance on escape. Zero escape tolerance One of the farming industry’s greatest environmental challenges Salmon – the effcient fsh is that each year large quantities of farmed fsh escape from sea Compared to other sources of protein, salmon use the energy and farms. The escaped fsh pose a threat to wild stocks of salmon protein levels of feed very effciently. Other farmed animals that eat and trout. We have a responsibility to preserve the environmental concentrated foods produce less protein per ton of feed consumed. integrity that these stocks represent.
