Physiochemical characteristics of Lake Frierson were monitored biweekly from 15 May to 14 September 1979. Lake Frierson revealed intense thermal stratification in late May. Stratification continued until fall turnover in mid-September. The anoxic hypolimnion started at the 3.0 to 3.5 m sampling depth and continued to the bottom. During this time, evaporation accounted for the loss of 1.0 m of water. Data from the shallow stations revealed anoxia and oxygen values of 2.0 mgll or less on 2 dates, 10 July and 8 August 1979.

From 3 May 1979 through 9 November 1979, cage culturing of fingerling white amur, Ctenapharyngodan ideUa was conducted utilizing alfalfa pellets, catfish pellets, alfalfa and bermuda grass hay or aquatic vegetation as feeds. Feed utilizations, feed conversion ratios and growth rates were analyzed. Feed conversion ratios ranged from 10: 1 to 30: 1. Fish fed the catfish pellets or hay yielded poor growth. Those fed the alfalfa pellets were larger and achieved the expected stocker size. Mortality was a problem throughout the study period. Handling stress, agonistic behavior, and bacterial and...
