| Abstract | ||
| The effect of garlic extract on growth and survival rates of one day larvae of Litopenaeus vannamei shrimp was tested for 12 days .Six nutritional treatments each with three replicates were fed to shrimp larvae (average weight 0.0013g) including control treatment (unriched Artemia nauplii) and second to sixth Artemia nauplii enriched with 200, 400, 600, 800 and 1000mg garlic extract per kg, respectively. The one way ANOVA results showed that all treatments were different in terms of average weight and total length of larvae compared to control group. Shrimps being fed by Artesia enriched with 200mg garlic extract per kg food have the best growth, survival rates and length (0.0062mg, 81.6% and 10.6mm). Group 3 with concentration of 400mg garlic extract per kg of feed followed by control group showed better growth and survival rates in shrimp larvae than other treatments but the lowest survival rate evaluated in shrimps fed by Artemia nauplii enriched with 600, 800 and 1000mg garlic extract per kg feed, orderly. Specific growth rates (SGR) for treatment groups 2 and 3 were higher compared to other groups. | ||
