In the study, effects of tetra (Cotinus coggygria) and laurel (Laurus nobilis) on growth rate (SGR), feed conversion ratio (FCR) and survival of cultured rainbow trout (Oncorhynchus mykiss) were evaluated. Rainbow trout juvenile with average weight of 66.13±0.94 g were fed with five different experimental diet including control group, 1% and 1.5% tetra and 1 % and 1.5% laurel during 8 weeks.
