Variation in meristic characters of a tilapian fish, Tilapia zilli (Gervais, 1848) from the inland water bodies in Libya

TL;DRAbstract

Meristic characters were compared in samples of the tilapian fish, Tilapia zilli (Gervais, 1848), collected from lake Ain Ziana, lake Tawrqa, and Ojala area, Libya. The significant difference in the number of vertebrae and the pectoral fin rays provide an evidence of the existence of three general groups or populations in the three study areas.
