Four hundred and twenty-seven stone loach (Barbatula barbatula) were collected from a 2nd order stream of the River Danube from April to November, 1996, to assess life-history characteristics. The von Bertalanffy equation of growth was: Lt=132{1-exp-0.3398(t+0.513)}. Survival rate was low, 4+ were the oldest specimens caught. No significant differences were found in the overall sex ratio 1:1. Stone loach were fractional spawners and first spawned at the end of the second year of their life. The equation between fish length and fecundity was: F=64.993 exp 0.0407L. Age groups II and III made the major contribution to population fecundity, although age group IV gave a noticable share as well. Almost the same quantity of energy was allocated to reproduction as to growth/maintenance in the three age groups. Stone loach in this small, submountain stream had a life-history tactics which can be characterized by medium growth rate, a trade-off between reproduction and growth/maintenance, early maturity, low number of age groups and low fecundity.
