Big fish
Well 20,000 gallons are needed for breeding sterlets and at a gallon of dirt every 5 seconds or so (the very fastest) thats ~ 28 (wo)man hours of very fast digging You and your pops could do that in a weekend add 12 hours for the cement and you are set in two or three weekends of coarse for an 8 foot (average) deep pond you need at least 320 square feet but thats not too bad is it.
