Description
The color of saugeye varies between olive green to gold but most individuals exhibit distinct dark saddles extending across the body.[1] Additionally, saugeye exhibit distinct streaks across the dorsal fin that frequently have one to two rows of spots along the base. Sauger will have multiple rows of spots while walleye only exhibit indistinct crescents across the dorsal fin.[1] Saugeye are difficult to identify based on external characteristics alone due to their similarity with both parent species. For example, 27% of presumed walleye sampled in the Ohio River were later determined to be saugeye through genetic techniques.[2]
Diet
Like walleye and sauger, saugeye are predominantly piscivorous. Prey consumed ultimately depends on location and prey availability, but saugeye diets primarily consist of centrarchids, cyprinids, and clupeids.[3][4] In many cases, saugeye are stocked to utilize abundant gizzard shad,[4] a prey item they readily consume.[5]
Reproduction
Saugeye are produced by crossing the eggs from a female walleye and sperm from a male sauger.[3]
Management
Saugeye are raised in hatcheries and stocked in the U.S. to provide an additional fishery opportunity for recreational anglers in reservoirs, rivers, and tailwaters. Some states that have stocked saugeye include Ohio, Tennessee, Colorado, and Nebraska.[6] Some saugeye stockings occur where habitat is considered too warm or eutrophic for walleye. [7]
In some waterbodies, saugeye occur naturally[8][9] and backcross with sauger or walleye.[10][11]
