abstract
The olive Ridley Sea Turtle are smallest and most abundant of all species of sea turtle found in warm and tropical waters, primarily in the Pacific and Indian Oceans. The research work was carried out during the period from September, 2017 to April, 2018, on stranded Olive Ridley Sea Turtles (Lepidochelys olivacea) that were stranded off on East Coast Beach along Chennai coast and maintained at the rescue center of Trust for Environmental and Education (TREE) foundation Tree Foundation, Vettuvankeni, Chennai, Tamil Nadu. The blood samples are taken from Olive Ridley Sea Turtles that are at the rescue and rehabilitation centers. The blood cells which were identified by differential count are mature erythrocytes, heterophils, eosinophils, lymphocytes, monocytes and thrombocyte. The clinical parameters such as Haemoglobin (Hb) was (85.71±11.96), Packed Cell Volume (PCV) was (0.29±0.04), White Blood Cells (WBC) was (5.78±0.85) and Red Blood Cells (RBC) was (0.60±0.06) evaluated for the rescued Sea Turtles. These Sea Turtle undergoing rehabilitation gives the critical parameters which are intended for health evaluations of sea turtle in rescue centers.
