Abstract: This paper reported morphology,growth character and kayotypes in Tilapia buttikoferi whose variation in the major measurable characters and their ratios in the tilapia was analysed.The results showed that the fish has cycloid scale and two lateral lines on its body surface.The relationship between body length and body weight is expressed as the equation:W=2.03×10-2L3.231(R2=0.9883).Adopted the PHA intra-cultivation,the kidney cells of the tilapia were taken out to make the metaphase chromosome specimens by air-drying method.The chromosome number of the tilapia is 2n=44 and the karyotype formula is 6sm+26st+12t,NF=50.Compared to Oreochromis aureus and Oreochromis niloticus,there are similar in the morphological character and karyotype.
