cecil,

 

how are your trouts thisdays? Growing i presume? What size (grams), are they now? Did u had some troubles with some illness to the fish?

 

 

Trout are between 3 and 4 inches. Feeding well every three hours. Act like they can't get enough to eat at feeding time. 

No illness but some seem to have slightly short gill covers. Could be genetic, a vitamin deficiency, or damage from moving them. One expert said the gills covers on the ends are very transparent at this stage so they may just look that way. 

They are now free swimming in the tank vs. a floating cage in the tank. 

Some will go into the outside pond in a couple of weeks, some will be sold, and the rest will be planting in a nearby stream with permission from my department of natural resources. 

I had to put a screen on top of the tank. I've had a few jump out!

The cool thing is now that they are free swimming in the tank, I am not seeing the waste on the bottom of the tank I did when they were in the cage. The movement of the fish and the side drain - plus purging the bottom drain at least twice a day -- is removing solids, and moving the rest to the filters.  When I drain the fish tank down to a few inches, and replace with fresh water, there isn't much waste left around the drain. What little there is, is pushed into the drain with a small aquarium net to be sucked out. 

They are also now actively swimming against the centripetal flow created by the discharge from the sand and gravel filter and the discharge from the chiller. This not only reduces their effort to get oxygen (ram ventilation), but it keeps them occupied and less likely to fin nip etc. And they are evenly distributed in the water column. 

I will include a couple more photos when I get the chance and access to the wife's iPhone camera. She is out of town right now due to the passing of my mother-in-law.

Probably won't be selling some of the fish to the prospective buyer for his pond. His new pond is having turbidity issues and I have referred him to a source for larger rainbows. From my experience the smaller trout do not tolerate turbidity well especially if it is continuous. 

No big deal as I will hold on to more trout and/l or plant more in a local stream with a blessing from the department of natural resources (permit required.)

Thank you Ande. My mother-in-law was sweetheart and fun to be with. And she liked me! Not a lot of son-in-laws can say that! :)  

She fought kidney failure for the last two years and a heart attack and subsequent congestive heart failure was the final coup de grace. 

For those of you that have high blood pressure, you need to do what it takes to bring it down. It will destroy your kidneys and other organs, and dialysis three times a week is no picnic even for the toughest people.

Trout are now free swimming in the outside trout pond. I initially put them in a floating cage and noticed about 20 swimming in the pond. What the heck? Turns out I missed a seam in the floating cage and they were escaping. Since it wasn't practical to fix the fish cage with the fish in it, I decided to just free the fish. The first couple of days they kept circling the pond but have now settled down to the south side of the pond mostly in the vicinity of the pier where I have concentrated feeding them. 

I need to get stakes up soon to keep a Great Blue Heron out of the pond. They seem a little too deep for the heron to reach, but better safe than sorry. I need to also cross some lines across the pond in case a Kingfisher shows up.

Hi Cecil

Did you get a estimate or count, on the number of fish hatched ?

cheers

Yes much less than I thought but still far more than I need. 717. (717 fish were planted into the pond).

Have seen some trout scattered in the pond. Some look close to 5 inches and  quite healthy looking. Saw a couple that appeared much smaller. Either runts or brook trout vs. brown trout. They all still have parr marks. 

Water temp in the pond is gin clear and in the low to upper 50's. Will wait as long as possible to crank up the well due to cost and in injection of iron particles that may irritate the gills of smaller fish. A source once told me once they reach 4 inches small amounts of iron aren't a problem. 

Today I installed a membrance diffuser in the middle deepest area for mixing of the water column. (Depth about 10 feet). Will probably run it mostly at night depending on air temps. Once the well is running will run it 24/7. From my experience mixing the water column doesn't warm the water much when the well is running even when air temps are in the 90's (32 to 35 Celsius). Water temp of the well entering at 45 gpm is about 52 F. ( 11 Celcius).  In mid summer below a few inches the water temp is 62 F. (16.7 Celsius) all the way to the bottom.

Sorry no pictures. Would need an underwater camera for that.
