Rearing of Rainbow Trout Fry

[fischcrazy]

I have a few dozen fry that finshed up thier Alevin stage last week, i transferred them to a fiberglass holding tank until they reach thier Parr stage, and will restock them then. The tank ranges from about 54-68* and theyre currently only eating capelin eggs (cant get them to take ground feed pellets), fed about 1/4 of the egg sack daily throughout the day. Is anyone familiar with rearing them? Growth rate, suggested foods, and if a few would be okay in a display ranging between 68-71*

@ Cecil b keeps them ,they should be kept below 60 (or better yet in the 56 to 45 degree range)

Optimum temp range for eggs is low 50's F. Alevins, fry , and fingerlings you can bump it up a low to the mid to upper 50's.

You need very fine feed for the fry starting at a powder size and working up to couple larger sizes as they grow larger. Keep in mind they need to be fed up to 8 X per day.

Obviously it doesn't make sense to buy the typical quantities for the few fish you have, so I would suggest buying smaller quantities from the folks at Allied Aqua (listed as Cichlid feed but same protein, lipids etc.)

I'm now getting the small quantities I need now from Shelby Fish Farm in Anna, Ohio. I'm only hatching about 1000 brown trout eggs presently so once they are ready to feed I probably won't go thorough a 2 lbs. of fry powder until they are ready for the next size feed up. Makes no sense to buy a big expensive bag and have it go to waste.

The eggs in a floating basket I made from a laundry basket, nylon screen, and silicone. Pieces of swim noodle keep it floating. A piece of wire bent in a 'U' keep it in place in the circular tank.
