Abstract

In this study, the growth characteristics of Softmouth trout (Salmo obtusirostris Heckel 1851, Acinopterygii, Salmonidae) from the Vrljika river were described. Samples were collected via electro-fishing and were arrived from all along the river; however most of the samples were taken from in between the rivers source and the bridge Kamenmost. 212 specimens were analyzed and fish scales from 56 specimens were processed. Lengthweight relationship, condtiion factor and parametres of growth were determined. The mass of the analyzed fish specimens ranged from 13 to 1804 grams, while the standard lenght ranged from 99 to 495 mm. The growth rate showed to be of izometric nature, while the contition factor was highest during June at a value of 1.823. Von Bertalanffy growth equation was obtained on the basis of length frequency, using the computer programe LFDA 5. The performance of growth is 5.87
