N: sample size; L: length (cm); W: weight (g); Min: minimum; Max: maximum; a: intercept; b: slope of the equation; SE: standard error; CI ( b): confidence intervals of b; r ²: coefficient of determination; p: significance of the regression, with p significant at <0.05; K _n: relative condition factors. Significance was determined by the t-test to verify if b was significantly different from the consensus ( b = 3). The growth behavior was based on b. GLE-5: 5g/kg of guava leaf extract; GLE-10: 10g/kg of guava leaf extract; SGLE-5: 5g/kg of star gooseberry leaf extract; SGLE-10: 10g/kg of star gooseberry leaf extract; MxLE-5: 5g/kg of mixture of GLE and SGLE; MxLE-10: 10g/kg of mixture of GLE and SGLE.
