Marine finfish require long-chain (LC) polyunsaturated fatty acids (PUFAs) for normal physiological function, and because these LC-PUFAs cannot be synthesized by the fish, they must be obtained from the diet. Three LC-PUFAs¿arachidonic acid (ARA; 20:4[n-6]), eicosapentaenoic acid (EPA; 20:5[n-3]), and docosahexaenoic acid (22:6[n-3])¿are especially important for growth and development of marine fish embryos and larvae. We supplemented ARA in the diet of Yellowtail Seriola dorsalis to determine whether ARA levels have an effect on egg and larval quality. Two experimental diets were offered to replicate groups of Yellowtail held in 10-m3 tanks under ambient water temperature and photoperiod conditions. The reference diet (REF-D; 1.4 g of ARA per 100 g of total fatty acids) was a commercial premix (BioVita Starter Mash; Bio-Oregon) without ARA supplementation; the ARA diet (ARA-D; 4.7 g/100 g total fatty acids) was the commercial premix with 1.0% concentrated ARA oil (40% ARA,
