Feeder fish stock

[SaltyCrak]

Hi

I need to build a pond to breed any low maintenance feeder fish (goldfish, etc.)
But I'm not sure what kind of requirements I need for them.
I need them to breed rapidly!
So:
1. What fish should i use?
2. It gets fairly cold where I live (not snow or anything like that), so would I need heaters for the pond?
3. What would be decent dimensions for the pond to be so that the fish can spawn and grow rapidly?

Convicts or livebears....

A couple of rubbermaids with live plants.

does feeding convicts to your fish deplete them of vitamins,like goldfish?

you could just use a stock tank to breed fish, not a pond.

temp won't be an issue with goldfish....mine survive with the top of the pond being frozen

Warmer temps. and water changes will help w/ growth.

livebearers will breed the fastest and are inexpensive to maintain. a heater would be necessary to keep livebearers outside year round. the size of the pond wouldn't need to be huge. even a 500 gallon would be overkill
