Impact of endosulfan on certain hematological and biochemical parameters of catfishLabeo fimbriatus: Sublethal study

Abstract

Hematological and biochemical parameters are routinely used as indicators of the physiological or sublethal stress response to endogenous or exogenous changes in fish. In this work, the sublethal toxic effects of endosulfan (0.002 mg l⁻¹) on certain hematological and biochemical parameters of Labeo fimbriatus were examined for 28 days and the analyses were made on 7, 14, 21, and 28 days. Endosulfan caused significant lower value of red blood corpuscles (RBC), hemoglobin, plasma glucose, and protein levels when compared to the control groups (p < 0.05). However, white blood corpuscles (WBC) increased throughout the study period. The results indicate that a low amount of endosulfan alters the hematological and biochemical parameters of fish, which can be useful in diagnosing the structural and functional status of fish exposed to toxicants.

A Review on Toxicity of Pesticides in Catfishes: Reproductive, Haematological and Biochemical Aspects

“…Internal changes induced by pesticides are mostly at haematological, biochemical, and genomic levels [1,4,9]. Hematological and biochemical parameters are consistently used as indicators of the physiological or sublethal stress response in fish [14].…”

Digestibility and digestive enzyme activity in Labeo fimbriatus (Bloch, 1795) fed periphyton grown on sugarcane bagasse

“…Though slow-growing, this medium sized carp is in good demand due high market value, excellent flavour and meat quality especially in peninsular India (Basavaraju et al, 1995). Published work on L. fimbriatus is limited (Mridula et al, 2003;Saravanan et al, 2011;Rao 2011;Swain et al, 2013). L. fimbriatus is basically a benthic fish which graze on algae, protozoa, rotifers and diatoms that grow on submerged rocks and twigs (Bhatnagar and Karamachandani, 1970;Talwar and Jhingran, 1991;Das, 2011).…”
