Intensive Culture Of White Amur In Cages

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 fungal infections appeared to have been the causative agents.
