In this study, the comparative effects of arachidonic acid (ARA) enrichment of the concentrated food and live feed (Artemia nauplius) were investigated on growth rate and reproductive indices in zebrafish (Danio rerio). Thirty-day-old juveniles (n = 400, with an average initial weight of 0.125 g) were randomly distributed in six treatments (each in three replicates) in eighteen 10-L aquariums (with a stocking density of 15 juveniles per aquarium). Fish were fed with concentrated diet containing three levels of ARA (0, 1 and 2% in the diet) and live feed (Instar II Artemia nauplii) in three levels of ARA (0, enriched with 1% and 2% of ARA) for 60 days until sexual maturity. The results of Two-Way ANOVA showed that the final body weight, body weight gain rate (%), and female’s reproductive indices were not affected by the combined effects of two factors; food type and ARA levels (p>0.05). Body weight in fish fed with concentrated diet containing 2% ARA was significantly higher than compared with the other treatments (p |
