We have a fairly good dept here at UC Davis.

Another issue I hate, and many trout fisherman all over might not like this, but dumping and stocking lakes, especially the pristine alpine lakes with few if any naturally occurring fish, adds what to these lakes?


Lots and lots of PO4 and NH4.
Even with "catch and release" (Catch and Kill I call it), there's still huge % die offs due to dropping the fish/transport/initial fish kills, lack of behavior to eat the wild foods instead of trout chow from the hatchery.

All these dead fish end up rotting and adding as huge amount of NH4 and PO4 to these lakes, then they get algae and turn green.

These frigging fishman and Fish and Game it seems to me...........are ruining such wonderful lakes and polluting them to the point they are nasty.

There's no management, no preservation, no ethical catch and release methods, look at the rates of mortality. Some at 20%, some at 80%. It's pretty high and very wide ranging.

Still, if you wanted a good research project, looking at the impacts of Fish stocking to alpine lakes(Not a bad place to do the research huh?) to water quality, algae blooms would be a good project.

It boggles my mind these fish folks cannot put 2 and 2 together.
Placing a concentrated form of PO4 and N into these systems year after year so the fishermen can go kill them over and over again.

That waste ends up somewhere.
Some gets flushed with spring rains, snow melt.
But a lot does not............
