Fish Stocking/Introduction

Hey all,

Just looking for some good resources on fish introduction, fish care, and figuring stocking density. I have a few resources but I'm struggling with some understandings. 1lb fish per 5-10 gallons of water, other folks (Bright Agrotech/SRAC) suggest introducing total number of fish to that ratio then feeding them a high amount to get them up to weight.

What have ya'll gone by?
