Fishery and Sea Resources2.3.2 Data AnalysisResults are presented as mean values ±standard deviation (S.D.). Statistical analyseswere performed using the SPSS 11.5for Windows (SPSS Inc, Chicago, IL,USA). One-way ANOVA at the 5% confidencelevel, was conducted to test ifthere were significant differences amongthe three feeding trials. Normalityand homogeneity were verified by Kolmogorov–Smirnovand Bartlett’s tests, respectively.Having demonstrated a significantdifference between the groups with theANOVA, the Tukey’s test for post-hoc multiplecomparisons was applied.3 Results3.1 Growth performanceAll dietary groups consumed the furnishedfood, and a survival of 100% was observedin all treatments. In Table 1 were reportedmean values ±S.D. for every index of eachdietary group.The maximum weight increase was foundin the bogue-based dietary group thatgave an absolute growth rate (AGR) of13.0 g·day −1 . Octopuses fed the mixedand mussels diets had lower increases inweight. These equated to absolute growthrates of 8.9 and 7.2 g·day −1 , respectively,although these differences were not significant(p>0.05).The animals fed with the mixed dietshowed a better ingestion rate (AFR) withrespect to other groups, in a significant way(p
