Gone for a couple days and this thread explodes. Too bad it wasn't as simple as shutting down the waterfall.
High gas pressure persists for weeks in the river we study. In fact most of the fishkills occur about a month after the high flows that created the high pressure end. The flow slows down and the depth of the river decreases. The high gas pressure remains, but the fish are not able to get deep enough to compensate for it.
It doesn't seem like it could persist for so long in a 300 gallon tank though.
I guess I'm on the "its coming from the well" bandwagon now. I know fish hauling trucks have some sort of mechanism for removing excess gases (CO2 mostly) from hauling tanks. Maybe there is an expert here that could explain that?
I did not know that. Way to go, csteffen. Are you the guy that went to SDSU and will be attending MSU?
No, I am an Iowa State fisheries grad. I did attend grad school for a while at MSU though. TJSTUBBS is probably the one you are thinking about. The fisheries world is pretty small-TJSTUBBS almost rented the same house I lived in while in Mississippi (another fisheries grad student beat him to it). Small little house with a pack of scurvy dogs and 2 ponds to fish, what more could a person need?
