[#0000FF]I am attaching a copy of the marking report for 2017 referred to by Chris. It should provide some answers to your questions. But, as Chris has pointed out on other occasions, it is virtually impossible to track any given batch of hatchlings once they enter the lake ecosystem. Any numbers would be pure guesswork.
What is not guesswork is that there is a significant difference in the hatch and survival rate of eggs kept in a hatchery environment and those allowed to chance it in the wild. Good aeration, constant temps and a lack of predation in hatcheries just gotta result in more eggs surviving to the fry stage. But once they are flushed into the lake they are all subject to the same vicissitudes of walleye life.
