Meta-Analysis: The effectiveness of artificial diets to increase on survival rate of vannamei shrimp ( Litopenaeus vannamei)

Abstract

The use of artificial diets for shrimp culture has been widely used at this time, but it was not yet known how large the effect of artificial diets on the survival rate of Litopenaeus vannamei. This study aims to determine the effectiveness of artificial diets on on the survival rate of Litopenaeus vannamei by meta-analysis research. The measurement results obtained z-value of 5.336 and p-value of 0.001, this p-value was smaller than the significance value of 5% (0.05). Therefore, at a significant level of 95%Cl the correlation between artificial diets and the survival rate of vannamei shrimp was significant with a minimum confidence limit of 0.192 and a maximum of 0.343. Based on Egger's test, the z-value which was the magnitude of the regression coefficient is 1.714, while the p-value of 0.086 is greater than 0.05 which indicates that the selection of articles and the results of the study were not indicated by publication bias. In addition, the p-value > 0.05 indicates that the funnel plot was symmetrical. Therefore, the results of this study are very useful theoretically in the development of artificial diets for the survival of vannamei shrimp.
