The Protective Effects of Korill Product on Carp Fingerlings Reared in High Densities and Challenged with Albendazole Treatment

The objectives of the present study were to evaluate potential Korill (KO), a product based on krill oil, supplemented in fish feed (5 g/kg feed) alleviate density-induced stress carp fingerlings, and its protective capacity case anthelmintic drug administration (ABZ—albendazole). Thus, divided into four groups: LD (low density with normal feed), LD-KO KO supplementation HD (high HD-KO feed). During first trial, held under different densities fed for two months, following 2 × factorial experimental design. In second seven per tank subjected, one week, albendazole treatment (administered daily by an oral dose 5 mg/kg body weight). For both trials, blood plasma samples used quantify hematological biochemical parameters. results showed that diet alleviated negative impact ABZ liver function metabolic profile fingerlings reared high densities. addition, feeding improved lysozyme activity (LZM) therefore immune status fish, reduced oxidative damage liver, demonstrated decrease malondialdehyde (MDA) content increase total antioxidant (TAC).
