Relative Survival of Walleye Fry Versus Fingerlings in Two Illinois Reservoirs
Instead of hatcheries having quotas based strictly on number of fish, it would be more desirable to set quotas in terms of “hatchery benefit units.” This can be done once the range of the relative survival of different sized individuals in various lakes for different species is known. In 2 Illinois reservoirs, the relative survival of walleye fingerlings (Stizostedion vitreum) was 62.1 times greater than fry in Collins Pond and 15.9 times greater than fry in Little Grassy Lake.
