Summary The purpose of this study was to obtain data on biochemical activities associated with carbohydrate metabolism in the golden shiner caused by acclimatization and expand present knowledge of the seasonal changes in the carbohydrate metabolism. Fish were captured using gill nets in a channelized and an unchannelized stream in the Tar River water shed. Seasonal variations in body weights, the weights of the liver, its glycogen content, and two carbohydrate enzymes, glucose-6-phosphatase and glycogen phosphorylase, activity values were studied. The enzymes were assayed at 10° and 25°C to gain evidence of temperature induced activity. In general, the liver glycogen content decreased during the study. The phenomenon was accompanied by increased glycogen phosphorylase activity. The fish taken from the channelized stream were often smaller and the livers of these fish contained less glycogen. Some evidence of temperature induced activity was found in the glucose-6-phosphatase values. Some evidence of an inverse relationship in temperature induced activity was found in the glycogen phosphorylase values.
