Changes in some Hematological Parameters of Chelon Labrosus (Risso,1826) in Umm Hufayn - Eastern Libya During Different Seasons

Abstract

This study aimed to investigate the effects of seasonal variation on some Hematological Parameters of Chelon labrosus (Risso, 1826) in Umm Hufayn lagoon - eastern Libya, Mediterranean coast, and surface water temperature and salinity. The results revealed that the surface water temperature recorded (11 ±1.73) 0C between December to February and (23±0.00)0C between June to August, salinity recorded (4.67±0.88)% between December to February and (23±1.15)% between June and August, on the other hand, seasonal variation affected hematological parameters whereas (WBCs) reached to high during the autumn season and recorded the lowest level during the summer, also (RBCs) reached to high during the autumn and the lowest levels during the spring. Furthermore, (HCT) reached high levels during the autumn and the lowest levels during the summer, otherwise recorded (MCV) at high levels during the spring and the lowest levels during the summer, and (MCH) reached high levels during the spring and lowest levels during the summer, while (MCHC) recorded the high levels during the winter and lowest levels during the autumn and finally (PLT) reached to high levels during the spring and lowest value during the autumn.
