Key Points

To develop a population model for Isli trout and assess the impacts of restocking and fishing mortality.
Constructed a stage-structured population model focusing on Isli trout.
Evaluated different restocking strategies and their effects on population dynamics.
Analyzed data in a single-location endemic habitat.
Restocking significantly increased juvenile survival rates.
Fishing mortality had a negative effect on adult population metrics.
Optimal restocking strategies demonstrated a potential for population recovery.
