Coho Fecundity vs Fish Weight


In this graph we see a yearly comparison for Coho fecundity(average number of eggs per female) versus the average weight of the fish(in grams) after its been stripped. We also see the average length which does not vary much.

These numbers are taken during our eggtakes after we have stripped the eggs from the fish. Remember, we have also been holding them for 1 to 3 months before they have become ripe. They have not been fed and so they are a lot smaller than when they first came in to the river. We can also see that our average eggs per female Coho has been going down.
