Study of Spirulina platensis meal effectin diet for growth and survival of Litopenaeus vannamei Larvae
This survey was conducted to survey the substition effect of Arthrospira platensis and Chaetoceros muelleri as food for feeding Litopenaeus vannamei during zoea and mysis stage. Larvae were cultured in 30 L containers filled by 10 L at a density of 100 Larvae. During the experiment salinity was 30 ppt and the average of temperature , pH and DO were 31.4ºC ,8.03 and 5.3 mg/l respectively .Three diet treatment and three replicates consist of twomonospecific and 1 combination of two algae were designed. All treatments received Artemia naupli at 5/ml from M1 and micro bound diet at 6 mg/l/d. Survival and total length were measured in zoea and mysisstage.The result indicate that highest survival rate in Zoea (63.17±1 %) and mysis (45.3±1.2 %) was obtained in Chaetoceros (P<0.05).Maximum total length in Zoea (2.64±0.1mm) which there was not significan with Chaetoceros( P>0.05)but In mysis stage (4.44±0.09mm ) was obtained in combination of Chaetoceros muelleri and Arthrospira platensis ( P<0.05 ).The result of this survey indicated that combination of Chaetoceros and Arthrospira platensis is better for feeding Litopenaeus vannamei during zoea and mysis stage.
