AB  - The aim of this study is to determine the egg and larval growth performance of brown trout (Salmo trutta sp.) at a constant high water temperature under commercial farm conditions. Eggs were taken from 450 female broodstocks with an average weight of 5.09±0.29 kg. The eggs placed in the incu-bators were observed on the 14th day and kept at a constant temperature of 12.5°C. Then larvae began to hatch on the 29th day and all the eggs were fully hatched by the 31st day. The incubation period was determined as 350 days /°C. In the study, an average survival rate was determined as 21.07%±5.16%  until  the  end  of  the  larval  stage.  A  significant  relationship  was  found  between  the  rate of eggs that hatched and the survival rate after the larval period had ended (p<0.05). After 120 days  of  larval  feeding,  larvae  weighing  0.15  g  reached  9.26±1.13  g.  During  this  period,  the  feed  conversion  rate  (FCR)  and  specific  growth  rate  (SGR)  values  were  determined  as  1.21±0.09  and  1.23±0.72 respectively.
