Sažetak

The condition of endemic soft–muzzled trout Salmothymus obtusirostris from the Dalmatian river Žrnovnica was studied. The sampling results of the length–weight relationship in the post–spawning period showed as expected negative allometric growth with a low b–value of 2.26 (W=0.16.L2.26) and also negative relationship between condition factor and standard length (CF =2.775 — 0.051 SL; r = –0.767, p<0.01). Drop in condition occurs between 20 and 27 cm of standard length. These results indicate that the fish from this population partially start spawning in the third year, while most of them spawn from the fourth year on.
