• Use of raw materials from the same species as feed is not permitted.
• Ingredients that are genetically modified or produced using genetic modification are not permitted.
• The feed ration for carnivorous species of aquaculture animals can contain a maximum of 60% plant products.

Feed raw materials from wild fish can be used in KRAV-certified production under the following conditions:

• Wild fish must come from sustainable stocks and be environmentally certified by a KRAV-authorized certification body or
• At least 50% of the aquatic protein in the remaining portion must come from by-products. The rest must consist of a aquatic raw materials from species normally not used for human consumption and from biologically stable stocks.

Permitted additives:

• Feed pigment from shrimp shells, algae, fungi and bacteria cultures
• Antioxidants, vitamins, minerals, binding agents, immune stimulating substances of natural origin.

Prohibited synthetic/unnatural additives:

• Growth regulating agents
• Appetite stimulants
• Antioxidants

• Hormones

Not permitted in KRAV-certified aquaculture:

• Additives consisting of GMOs
• Additives produced using GMOs
• Genetically modified ingredients or ingredients produced using gene modification
• Gelatine from ruminants
• Products/ingredients that chemical solvents have been used in

FEED

• Must if possible consists of only KRAV-certified feed and/or feed material approved for use in KRAV-certified production originating in wild aquatic stocks. If such approved feed is not available, up to 5% of the feed (dry weight) can be of non-KRAV-certified origin. The dry matter level in the feed must be at least 45%.

FOR SALMONIDS AND PERCHES

• Salmonid fingerings must originate from domesticated fish.
• Roe and fingerlings from perches can originate from wild caught parents. Parent fish must be caught with gear that damages the fish as little as possible, for example fish traps.
• Use of gill nets is prohibited.
• Dumping of dead/dying fish or fish parts/residues is prohibited.
• Release of fish from the production unit is also prohibited.
• Packing materials must be recycled if possible.
• Dying fish should be put to death immediately. Dead fish must immediately be ground down and be conserved in acid or handled according to other approved treatment methods.
• Treatment against salmon lice all units must be handled isolated from the surrounding area  to achieve efficient control of the treatment concentration
• Minimise use of chemicals and reduce releases, as well as to achieve efficient treatment and prevent development of resistance against the medication used.
• Vaccination is permitted if it is established that there is a disease in the area and that it cannot be controlled using prophylactic production methods.
• Transport equipment must be disinfected when used for transport.
• Synthetic stimuli and/or tranquillisers in connection with transport are prohibited. Sodium chloride can be used in connection with transport.
• Capture methods for salmonid fish can be a tight collection bag, vacuum bag, net or fish trap. Fish caught using a hock and line cannot be KRAV certified.

FOR MUSSEL FARMING

• Bottom-based cultivation of blue mussels is prohibited.
• Use of chemical additives is prohibited for processing of mussels.

FOR CAPTURE-BASED AQUACULTURE

• Vaccination is permitted.
• Synthetic stimuli or sedatives are prohibited in connection with transport.
