Hello Friends, certainly delayed but looking forward to coming up in a few weeks!

 

I searched for a thread for this, but really didn't find anything recent. Any tips and/or suggestions to keep rainbows or other minnows alive between trips? I must throw out a hundred dollars worth of minnows each year and wondered if a simple aquarium with a stone aerator would keep them alive for a week or so as we generally come up every other weekend.

 

I am sure there are better ways, but just a thought as we have an old aquarium or two sitting around.

 

Thanks

That will work for awhile but if you have a large number of minnows in the tank you will quickly build up contaminants that will kill them.  You need a way to change the water.

 

I have a 25 gallon double-walled plastic tank in my boat house.  I use a submersible pump to pump fresh water directly from the lake to the tank.  This keeps the water fresh and the minnows aerated and fed.  When I'm around I keep a bubbler going and just recycle water once a day.  If I'm going to be gone for an extended period of time I will use a timer on the pump.  Last year I kept several dozen minnows alive for several weeks at a time.  The whole set up cost me a couple hundred bucks but like you, over the years I've thrown hundreds of dollars of minnows away.

I know a couple folks that have used old freezers with bubblers and trickle water from a faucet and have a small overflow...   You need something to keep the water clean.  A little flow from the well or other not chlorinated water source will do it.   Also keeps the water cool, especially if the container is an old cooler or freezer.

After all of that work, it seems to me that floating them under your dock is just about as good of a solution....unless the otters open it! The mass of minnows in a tiny container always seems to be the big issue.

 

I've toyed with taking an old stock pot, drilling small holes all around it, putting a few rocks in the bottom and sinking it under my dock. That should keep them nice and cool and out of harm's way.

Thanks for the thoughts friends, I am guessing we will all be up there soon! Hoping for open water (Timbuktu to Scrubb Island) by Thursday. I may try an inexpensive ($19.99) cylindrical minnow trap and cover the two holes with some sort of mesh, put a rock in the trap and sink down from my dock (7 feet). Worth a try.

Make sure to wire it shut or the otters will clean you out. 😀

Nope.  If you have more than a handful minnows in the aquarium, aeration alone won't do the trick.  Unless you have a way to change water every other day or so nitrogen and other toxins build up and the minnows are toast.
