Tilapia: Perbedaan antara revisi

Multiple studies have evaluated the effects of adding flaxseed derivatives (a vegetable source of omega-3 fatty acids) to the feed of farmed tilapia. These studies have found both the more common omega-3 fatty acid found in the flax, [[Alpha-Linolenic acid|ALA]] and the two types almost unique to animal sources ([[Docosahexaenoic acid|DHA]] and [[Eicosapentaenoic acid|EPA]]), increased in the fish fed this diet.<ref>{{cite journal |display-authors=1 |last=Shapira |first=N |first2=P |last2=Weill |first3=O |last3=Sharon first4=R |last4=Loewenbach |first5=O |last5=Berzak |title=''n''-3 PUFA fortification of high ''n''-6 PUFA farmed tilapia with linseed could significantly increase dietary contribution and support nutritional expectations of fish |journal=J.
