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.

PL

Porównano cechy merystyczne tilapii, Tilapia zilli (Gervais, 1848) z trzech rejonów; jezioro Asin Ziana, jezioro Tawrqa i stawy w okolicy Ójala w Libii. Ustalono, że ryby z tych trzech prób wykazywały statystycznie istotne różnice w liczbie kręgów oraz promieni płetw piersiowych. Jest to dowodem istnienia trzech grup lub populacji we wspomnianych trzech rejonach badawczych.
