RICHMOND – Conditions brought about a small fish kill that affected the gizzard shad population in July and a worse problem in late August at Ray County Lake, Department of Conservation information stated.
Gizzard shad can become overpopulated, and the fish kill benefited the overall health of the lake.
Area fisheries biologist Eric Dennis said high water temperature and a couple cloudy days likely brought on the common low-oxygen problem. When a pond does not get direct sunlight, aquatic plants do not produce oxygen.
“We estimated a loss of approximately 5,000 shad in that July fish kill,” Department of Conservation information stated.
