Hematological characterization of Nile tilapia (Oreochromis niloticus, Linnaeus, 1758) reared intensively in a recirculating aquaculture system in relation to water temperature

Catalina Ciortan Mirea

Abstract


The aim of this study was to obtain a basic knowledge of the hematological response of Oreochromis niloticus mantained in different tchnological condition induced by different temperatures. Nile tilapia (Oreochromis niloticus, Linnaeus, 1758) with average weight of 33,5±1,0 g, they were stocked in 12 rearing units at 20, 24,30 and 280C (control) water temperature for 30 days. Diet of 41 % protein was offered as feed, 3 times daily. The sampling of Oreochromis niloticus blood from the four variants before and after the experimental trial allowed determination of hematological indices. Red blood cel count (RBCc), hematocrit values (Hct), hemoglobin concentration (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular concentration (MCHC), glucose and protein from blood were measured and analysed, with routine methods udes in fish hematology.
