Slide1
Statistical analysis (PERMANOVA) for the
potential of black soldier fly larvae (BSFL) as a shrimp feed ingredient to
replace partial
fishmeal
Bell Lin
Slide2Goal
& HoHa
Using statistic approach PERMANOVA to find the difference of shrimp growth and survival performance between four diets
HO: No statistic difference between four shrimp diet treatments on shrimp performance
HA: There is a pattern between four shrimp diet treatments
Slide3Dataset Description
16 samples and 4 variables
Experiment duration: 84 days
Four groups of samples, each group has four replicates
CTL: Control group diet 25BSF: 25% of the fish meal was replace by BSF 50BSF: 50% of the fish meal was replace by BSF 75BSF: 75% of the fish meal was replace by BSF Variables:Survival: Shrimp survival rate (%)Yield m2: Shrimp Yield in grams/m2SGR d: Specific Growth Rate per day (%)FCR: Feed conversion rate (%)

Slide4Dataset Processing
No samples and outliers discarded.
Large Skewness for
SGRd
and FCR Tried to perform log transformation for SGRd and FCR columns but didn’t change the skewness much. Performed general relativization
Slide5Dataset Analysis
Slide6Results Interpretation
F(12,3) = 1.806
Pseudo F range from 0 to 100
P-value not significant (larger than 0.05)
Slide7Results Interpretation
Slide8Results Interpretation
Not significant between any of the groups!
Slide9Discussion
Fail to reject Ho: No statistic difference between diet groups on shrimp performances.
What I learned:
Slide10Next step
Re-analysis: Perform ANOVA, look at one variables at a time.
Next step:
Formulate a feed formulate replacing fish meal with 100% BSFL.
Replace different proportion of fish meal with BSFL on different aquatic species.
