Azteca, YP are a focus of research for aquaculture. Though you probably have it already, the link below might be useful. As with any forage species, attainment of desired size in a single growing season is the biggest challenge to overcome.

For 1000 perch, which size, water change, oxygen, which fish is best for flattening, a friend told me that Yellow-perch is good for flattening because he is less cannibalism than other.


On page 35 of the above manual they discuss the commercial grow out of YP in ponds. I will scale the results in numbers suitable a small project. The culture consisted of a two stage process where fingerling were raised to a mean length of just under 5" in year 0 at densities of 1.07 fingerlings per ft^2. 1000 stage one fingerlings would require ~ 1000 sq ft at that density. If you wanted only females for the subsequent growout, double that size and stock fry to yield 2000 fingerlings (based on the historical fry mortality). At this stocking rate, the yield is between 1100 - 1200 lbs per acre. So this is manageable with no aeration or water exchange.

The grow out stage was with densities of .3256 fingerlings per ft^2. So the grow out space required for 1000 fingerlings would be ~3100 ft^2. At this density, the biomass of will attain => 4200 lbs/acre. So at this stocking rate aeration/water exchange may be required. I won't be able help with what is required but aeration has the potential of being sufficient. One approach may be to begin harvesting fish midway through the grow out so that the standing weight remains manageable through the season (you might achieve >2000 lbs/acre with this approach). In whatever water you have overwintered, you should probably let them spawn before stocking for grow out. The second stage will produce fish in excess of 9".
