Comparative Study of Season-based Haematology of Mugil cephalus and Sillago sihama from Ennore Creek, Southeast Coast, India

Abstract

Background: Haematological parameters are valuable indicators of fish health status. This study aims to provide baseline data on the blood profile of Mugil cephalus and Sillago sihama from Ennore Creek, southeast coast, India and UPRS, Arambakkam from September 2022 to August 2023, at bimonthly intervals. Methods: Blood samples of the said two fish species were collected from Ennore Creek and UPRS Arambakkam during all four seasons to analyse haematological parameters like WBC, Lymphocytes, RBC, HGB, HCT, MCV, MCH and MCHC. Results: The values of haematological parameters were found less in these two fish of Ennore than Arambakkam. Between the two stations (Ennore and Arambakkam), the differences in the values of haematological parameters were found to be highly significant (p less than 0.01) for both fish. Reduction in the values of haematological parameters of these two fish in Ennore Creek showed that the fishes exposed to pollution-induced stress make them weak, anaemic, and vulnerable to diseases.
