Abstract: (3778 Views)
Nutrition and the use of valuable nutrients is one of the most important issues in the aquaculture industry. In this study, the algal species I. galbana and P. lutheri alone and in combination with C. mulleri were incorporated in the diet of white leg shrimp larvae (L.vannamei) and the survival and growth rate of shrimp were investigated. This research was carried out in Persian Gulf & Oman sea Ecological research institute in July 2016. The experiment was carried out from nauplii 6 stages to PL10 and the shrimp were fed six times a day over 16 days. Six treatments including single species of I. galbana, P. lutheri, and in combination with C.mulleri (as control) were in 3 replicates. At the end of the feeding period, the results of the experiment indicated that C treatment had the highest survival (72%) and the lowest survival was observed in B treatment (47%). There were significant differences among treatments (P≥ 0/05). The maximum (8.02mm) and the minimum (7.23mm) length were observed in F and B treatments, respectively. However, there was no significant difference among treatments (P≤ 0/05). The highest survival rate in salinities 45 and 53 was observed at 98% in E treatment and 95% in F treatment. No significant differences were observed in survival among treatments. Thus C.mulleri is an essential main species for feeding white leg shrimp larval stage and I.galbana can also be supplemented for increasing nutritional value that could be suitable to improve quality and growth factor of shrimp larvae.
