Salmon swim upriver, to be eaten by 59ers, who toss the scraps into the woods.  Small critters eat what flesh/soft bones are left, insects move in, then bacteria, remains fertilize the soil so berries can grow which the 59ers eat while waiting for the salmon.  Meanwhile, the salmon who escape the 59ers spawn, die, and sink to the stream bed, where little fish pick away and even littler things do their thing, thus producing even littler things which the salmon fry eat. 

You forgot the part where my dogs roll in the rotting dead ones.
