Distribution, Movement, and Habitat Preference of Saugeye in Thunderbird Reservoir, Oklahoma1

Ultrasonic transmitters were surgically implanted in a total of 30 saugeye (Stizostedion vitreum vitreum x S. canadense) in 1987 and 1988. Horizontal distribution, movement, distance from shore, depth, and habitat were determined during tracking of each fish. Saugeye were located ≤65 m from shore most frequently during all seasons except summer. Saugeye preferred open shore areas, and frequented submerged timber only during fall 1988 and winter 1989 when prey items may have been limited. Saugeye preferred depths of 0-3 m except in summer 1988 and summer and fall 1989, when no depth...


Growth and Food Habits of Saugeye (Walleye x Sauger Hybrids) in Thunderbird Reservoir, Oklahoma

Saugeye (Stizostedion vitreum vitreum X S. canadense) stocked in Thunderbird Reservoir from 1985-1987 were monitored for growth, food habits, and possible diet overlap with largemouth bass (Micropterus salmoides) as they progressed from age-1. Age-1 and age-2 saugeye attained mean length of 445 mm and 543 mm, respectively, by October. Food habits revealed saugeye 301-400 mm began converting from inland silversides (Menidia beryllina) to shad (Dorosma spp.) as their main food item. A predator-prey length relationship showed mean prey length was approximately 30% of predators. Diet overlap...


Growth and Food Habits of Age-0 Walleye x Sauger Hybrids in Thunderbird Reservoir, Oklahoma

Ninety-eight thousand walleye (Stizostedion vitreum vitreum) x sauger (S. canadense) hybrid (saugeye) fingerlings were stocked in Thunderbird Reservoir, Oklahoma, in May 1985, and 129,400 fingerlings were introduced in April 1986 to evaluate the possibilities of a superior put, grow, and take fishery where previous walleye fry stockings have failed. Saugeye showed rapid growth rates; age-0 fish attained a mean length of 270.8 ± 8.2 mm (mean ± 95% CL) by October 1985, and 256.1 ± 11.2 mm by October 1986. Both year classes preferred inland silversides (Menidia beryllina) as a forage species...
