Table 3.

Waste reduction index (WRI) and feed conversion ratio (FCR) of BSF larvae reared on different experimental diets consisting of coffee by-products (CB) enriched with different percentages of Schizochytrium limacinum (S) and Isochrysis galbana (I) microalgae and control diet (C) (mean ± SD; n = 6).

Diets	WRI (%/day)	FCR
5S	1.5 ± 0.1 ^dC	5.2 ± 0.3 ^aA
10S	2.6 ± 0.2 ^aA	7.21 ± 0.7 ^cB
20S	2.1 ± 0.3 ^bcB	5.6 ± 0.8 ^abA
25S	2.0 ± 0.2 ^cB	5.0 ± 0.3 ^aA
5I	1.2 ± 0.1 ^f^CD	5.8 ± 0.3 ^b^B
10I	1.4 ± 0.1 ^e^B	5.1 ± 0.5 ^a^A
20I	2.2 ± 0.1 ^b^A	9.5 ± 0.9 ^d^C
25I	1.3 ± 0.1 ^ef^BC	4.5 ± 0.5 ^a^A
C	1.2 ± 0.1 ^gD^D	34.2 ± 6.4 ^eC^D

Different superscript letters in a column indicate significant differences (p < 0.05): ^{a,b,c,d,e,f,g} small letters indicate a significant difference among all diets; ^A,B,C,D,E capital letters indicate a significant difference among diets consisting of coffee by-products (CB) containing different percentages of S. limacinum (S) and the control diet (C); ^A,B,C,D capital and bold letters indicate a significant difference among diets consisting of coffee by-products (CB) enriched with different percentages of I. galbana (I) and the control diet (C). Abbreviations of the experimental diet: 5S = 95% CB + 5% S; 10S = 90% CB + 10% S; 20S = 80% CB + 20% S; 25S = 75% CB + 25% S; 5I = 95% CB + 5% I; 10I = 90% CB + 10% I; 20I = 80% CB + 20% I; 25I = 75% CB + 25% I; C = 100% CB.
