 Orange roughy ("Hoplostethus atlanticus)" is an attractive food fish with 5.5% fat, where 90% of the fat comes as wax esters.Consumption of this fish gives no unpleasant adverse effects, most likely due to the relatively low fat content that provides approximately 10 000 mg wax ester per 200 grams serving of fish.In 2015 a randomized, two-period crossover human study, showed that EPA and DHA from oil extracted from the small crustacean "Calanus finmarchicus" was highly bioavailable and the study concluded that oil from "C. finmarchicus" could serve as a relevant source of the healthy omega-3 fatty acids EPA, DHA and SDA.
