Redd Superimposition and Egg Capacity of Pink Salmon Spawning Beds
A study of egg recruitment to pink salmon spawning beds in two southeastern Alaska streams (Indian Creek and Harris River) has shown that egg loss during spawning increases as the density of female spawners increases. Mortality was caused for the most part by superimposition of redds.A mathematical...
