cultivating food?

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? 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?

list of fish/tanks

tank 1 10 gal 5 upside down catfish, soon to have some molleys as my
parents fri grow to the size of not food

tank 2 10 gal 2 yoyo loaches, 3 glowlight tetras

Tank 3 20 gal 3 clown loaces, 1 zebra diano, and 4 red rasboros

all are planted tanks

TIA

Mosquito larvae are great for your fish. Depending on how far along
spring is where you live (here temperatures are just starting to creep
above freezing), you may already have hordes of mosquito larvae waiting
to be harvested in ponds and ditches around where you live.

Take care not to feed more than your fish will eat, and to store any
unused larvae cool, or they'll hatch into mosquitos in your house, and
you really don't want that.

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.

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.
