Abstract
Chub (Leuciscus cephalus) is widely spread fish species and it inhabits most of Europe and some parts of Asia. It is also the dweller of different sections of rivers and stagnant waters and it eats both - animal and plant organisms. Thus, it is a very useful species when different habitats, or same biotopes over the period of time are being compared.
Based on a number of published data on different habitats, the standard growth curve for chub in Croatia was calculated. Based on total length, Von Bertalanffy's growth curve appears to be:
Lt = 31,8 (1-e-0,28(t-0,04))
A comparative growth index for the first eight years of chub life was the lowest in the upper Kupa river (89,8 %) and the best in the upper part of the Lonja river (112,2 %).
The overall growth performance (phi-prime) is ϕ`=5,69±O,14. These data are discussed and compared with literature.
