At Fishery Station of São Bernardo do Campo, São Paulo State, Brazil, an experiment was carried out to investigate the seminal characteristics of 19 carps, Cyprinus carpio in six successive collects at 14 days intervals during 71 days period (Set/3/87to Nov/12/87). The seminal characteristics examined and the average values were: semen volume: 0,26 ml; spermatozoa concentration: 30,17 x 10^/mm3 , sperm motility: 91,41%; live spermatozoa by differential staining method: 96,81% and the methilen-bluereduction test: 285 seconds. The regression analyses showed a significative effect for third and first degrees curves for sperm volume and spermatozoa concentration and the equations were, respectively: : Ŷ= 0,168 - 1,948.10ˉ3 . X + 3,690.10 ˉ4 . X2 - 4,836.106 . X 3 e Ŷ = 39,923 - 0,293. X
