A Survey of the Subsistence Effects of n-3 HUFA Enriched Artemia nauplii as a Start Feeding for Caspian Salmon (Salmo trutta caspius) Larvae

This experiment was conducted with the aim of investigating the effect of using n-3 HUFA enriched Artemia Nauplii and newly hatched Artemia as a starter food for Caspian salmon (Salmo trutta caspius) larvae compared with artificial food. It was conducted in three treatments: artificial food, newly hatched Artemia nauplii and n-3 HUFA enriched Artemia nauplii during 15 days. Larvae fed with newly hatched Artemia nauplii did not show any significant difference in growth rate compared to larvae fed with n-3 HUFA enriched Artemia nauplii (P³0/05). However, both of these groups showed a better growth rate compared to larvae fed on artificial food. Larvae fed with newly hatched Artemia nauplii show no significant difference in survival compared with larvae fed with n-3 HUFA enriched Artemia nauplii (P ³ 0/05). However, both of these groups showed a better survival compared to larvae fed on artificial food. Overall, larvae fed with newly-hatched Artemia nauplii had a better performance and it was selected as a starter food for Caspian salmon larvae.
