I wouldn't add any perch to the until mid to late February since you caught gravid ones in early March last year. If you catch some now you could add some to the pond where you intend to grow them. You should get some natural spawning in that pond. Several thousand should survive with 10-16 adults in the pond. A fish farm near me harvested around 20,000 fingerlings in a smaller pond using 6-8 breeders.
