Abstract
The effect of Artemia urmiana nauplii enriched with flaxseed oil on growth performance, survival and fatty acid composition of severum, Cichlasoma severum, larvae (0.3 mg initial weight) was investigated through a completely randomized block design with two treatments, viz., (1) larvae fed with plain nauplii, (2) larvae fed with nauplii enriched with flaxseed oil, in three replications. Results of the first biometry (day18th), showed a significantly higher survival rate in treatment 1 (81.87±0.29%) than treatment 2 (68.83±1.62%) (P<0.05), but there were no significant differences in the specific growth rates, the average weight and length gains between treatments (P>0.05). At the end of the second period of the experiment (day36th), significant differences in growth performance and survival rate was recorded between treatment 1 (97.82 ± 1.09%) and treatment 2 (91.16± 1.34%) (P>0.05). The larvae was also found to convert n-3fatty acids to EPA and DHA.
