It has previously been reported that feeding diets rich in fish oil
(10% cod liver oil) slightly depressed growth and significantly
reduced feed efficiency in red hybrid tilapia (Ng, Lim, & Boey,
2003). The present study was carried out to evaluate the effects
of supplementing dietary fish oil on the growth and feed efficiency
of juvenile red hybrid tilapia and on the n-3 content of red hybrid
tilapia fillets
