Values represent the means of triplicate groups of treatment where the values within each row with different superscript letters indicate statistically significant differences (mean ± SEM; p < 0.05) and range values (minimum–maximum).
Diets represent FM20: fishmeal contents of 200 g kg–1, FM10: fishmeal contents of 100 g kg–1.
pH, potential hydrogen; DO, dissolved oxygen; TAN, total ammonia nitrogen; NO2-N, nitrite-nitrogen; NO3-N, nitrate-nitrogen; SS, settleable solids.
