Pond Boss Forums INTRO Questions & Observations Muck away after Rotenone treatment

Hi I finally got someone to do a fish kill with Rotenone but I have a question is it safe to start using Muck Away 3 days later without it affecting the muck remover because of the oxygen depletion

There should be NO oxygen depletion due to applying rotenone. Rotenone does not remove the oxygen(DO) from the water. That is a misconception. Rotenone is absorbed through gills and when in the blood interrupts oxygen transfer in the animals tissues / cellular structures.

Rotenone inhibits cellular respiration and the ability to use dissolved oxygen. In effect, the fish suffocate. Fish exposed to lethal rotenone concentrations move to the surface and gasp for oxygen AS IF the water was oxygen-depleted. However, rotenone does not reduce the amount of oxygen dissolved in the pond water.

MORE DETAILS – Rotenone interrupts aerobic cellular respiration by blocking electron transport in the cellular mitochondria through the inhibition of the enzyme NADH ubiquitone reductase, which prevents the availability of oxygen for cellular respiration.

I've had a die-off of large catfish in my pond. None of the scaled fish were affected. Could this be a Rotenone application by someone with bad intentions?

In the ponds that I have Rotenoned, I have not noticed the catfish being more susceptible to the Rotenone vs. the scaled fish. They ALL come up. Bullheads were the last ones to be affected in the ponds that I treated.

IMO no one as esshup suggested used rotenone to kill your fish. If they did more fish would be dying. It is not easy, in fact very difficult to kill just CC with rotenone. I wish it were possible.
