Illinois Trophy Muskellunge Project.

摘要

The purpose of this project is to maximize the efficiency of the Illinois fish hatchery system to produce muskellunge capable of reaching a trophy size to optimize the standing stock of trophy muskellunge in Illinois waters where the fish are stocked. The objective is to develop a muskellunge brood stock that can be used to produce all-female progeny for Illinois stocking programs. The specific objectives include: (1) to determine the muskellunge genetic sex-determination system; (2) to produce masculinized female muskellunge, rear them to sexual maturity and use their sperm to produce all-female off-spring; and (3) to produce intersexed female muskellunge, rear them to sexual maturity, and use their sperm to produce all female off-spring.
