Salmon life cycles from egg to spawning adults with text explaining each life phase.

This is fieldwork from a Chinook salmon egg survival pilot study in the Sacramento River. Egg boxes were placed in the river at different locations to collect data on egg-to-fry survival. Some examples of data collected include water velocity and river flow, gravel temperature, scour and deposition, and sediment type.
