Stream productivity. What is in your streams to feed juvenile fish?

I have been actively collecting video documentation of stream observations and invertebrate abundance. These records, when compared to adult returns, indicate the underestimated importance of the freshwater rearing productivity for salmonid species. There appears to be direct correlation of streams with depressed adult returns and the invertebrate populations that provide food for the juveniles within those streams.

It would be helpful if anyone out there could contribute to building on this information as to what available prey there is for juvenile fish in their local streams. What future does your local streams hold?? Please post and share any of your findings.

Marble river

Link river

Waukwaas creek

Lower Nimpkish

Upper Nimpkish-Gold creek

Note that the Upper Nimpkish is well known to have a collapsed steelhead population and has an equally depressed invertebrate population similar to Gold river.
 
The fatter they can get in fresh water the better

"It is too early to say much about the catches, but the fish caught so far are skinny, after using their fat reserves to survive the winter, said Dick Beamish, aretired B.C. fisheries scientist.

“We will see if it is common that most fish are skinny, as it will show that a fish has to be quite healthy in the fall to survive a winter in the Gulf of Alaska,” he said."
