Description:
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.
