Emamectin benzoate (EMB) is a potent neurotoxin agent, widely used for ectoparasites control in aquaculture, but their detailed toxicological implications in Labeo rohita are unknown. Thus, this study was conceptualized to determine the LC50 and to investigate the effects of two sub-lethal concentrations 1/50th of 96 h LC50 (1.82 μgL−1) and 1/10thof 96 h LC50 (9.1 μgL−1) on hemato-immunological and biochemical responses in L. rohita (mean weight 25.54 ± 2.3 g and length 10.35 ± 2.4 cm) for a period of 24 h, 48 h, and 72 h. LC50 of EMB were 163 μgL-1, 112 μgL-1, 99 μgL-1 and 91 μgL-1 at 24 h, 48 h, 72 h, and 96 h respectively. The safe limit at 96 h LC50 of EMB was 2.30 μgL-1. In EMB treated fish, red blood cells, white blood cells, hemoglobin, and hematocrit counts were reduced (p |
