I was along the Alouette River the other day and took notice to thousands of fry along the shoreline. I'm thinking these would be steelhead fry, am I right?

Also, does anybody know the average percentage of fry that make it back to spawn? There were literally thousands of these little guys in a small section (10 ft.) of beach water.

If you are sure they were salmonids they were probably a combination of coho and steelhead fry. Chum and pink fry will be gone to the chuck by now.

As for survival rates, if a doe coho lays 2500 eggs, generally 2 adults will return from them to spawn in their home waters.

How many of those eggs actually hatch into fry?

WOW, I'm curioius, where do you get these stats from? These odds are remarkable and they speak heavily to the need to protect and preserve these fisheries.

Actually those odds are the exactly what nature requires in order to maintain any population at a steady level. If every adult pair produces 2 offspring that reach reproductive age, the population will remain static. If every adult pair were to produce 3 offspring that reached breeding age a population would increase by 50% in just one generation.
