cultivating food?

Hi..

Hi all, It is now spring time and bug are starting to show
there signs. I live in northern canada. Edmonton to be
exact. and I am wondering what bug are good for my fish?

Your region might be rich in what we call "meadow plankton".
All you need were a self-made (bought?) net similar to an
extra fine butterfly net and of course access to grassland
or meadows. The yield are flies, plant lice, little
beetles, moths, grubs, butterflies, spiders, ants, larval,
grass-hoppers, other bugs.

An overplus of meadow plankton might be stored in plastic
bags in the food freezer.

an also how to cultivate said bug so I can use them in the
winter as well as not having to forage for them all the
time?

Water-fleas were another option having access to a garden,
balcony, buckets or rain barrels. You might overwinter some
water-fleas in buckets in a frost-free room for the next
outdoor season.

Indoors small flightless fruit-flies, grindal or water-fleas
were an option, too.

HTH.
