Colorado division of Wildlife had two rafts on the Rio Grande at the Coller public access (between Creede and South Fork) this morning.

The crews were shocking up fish that were then netted and put on board in live wells. Guys with the net missed about a third of the fish they tried to catch.

Three questions:

(1) What is the effect of the shocks on the nymphs in the water? I was standing on the bank and one of the crew guys advised me to keep my dog out of the water (I wasn't about to let her get in).

(2) After the fish are shocked, do they make their way back to the holding lies from which they were taken? The rafts moved about 1/2 mile downstream before beaching (I assume to measure and return fish to river).

(3) What is the mortality rate of the fish that are shocked? I saw a couple of fish that were netted pronounced "dead" and tossed up on the bank (perhaps they were aready dead--I don't know)?
