Abstract

Hybrid walleye is important for recreational fisheries and is a potential aquaculture species in the north central region of the United States. Stress related to intensive culture conditions has been documented to cause eye lesions in fish. Finfish eyes do not have eyelids, hence the cornea is permanently exposed to mechanical damage and toxic substances. We documented various disorders of the eye in juvenile hybrid walleyes reared in a flow-through tank system. Abnormalities include exophthalmia, enophthalmia, unilateral loss of globe and bilateral loss of globe. These lesions negatively affected body weight, specific growth rate and condition factor of hybrid walleyes reared in tanks.
