1. Stream and Lake Population Analyses. 



The objective is the determination of existing condition of fish populations 

 as an aid in revising stocking programs for Federjil hatcheries. Samples are 

 taken to show species, age, growth, and condition. Sampling methods include 

 portable stream shocker and graduated mesh gill nets.
