Abstract
The spatial pattern and physical characteristics of chinook salmon (O. tshawytscha) redds was studied with respect to length of redd occupancy and when redd construction began. Spawners arriving 1st deposited their eggs in larger redds constructed in deeper, slower moving water. Redds constructed by late arriving fish were smaller on average and were usually located in relatively shallow, fast-flowing water. Late arriving fish also had a shorter average redd residence time. Progeny of early arriving spawners may have a selective advantage over progeny of late arriving fish in the same run.This publication has 3 references indexed in Scilit:
