Abstract

Growth of largemouth bass, Micropterus salmoides, in Lake Rebecca, Minnesota began in July and was associated with increased food consumption. Decreased maintenance levels and increased food consumption combined to produce maximum growth in September. Body growth and in vitro [14C]‐glycine uptake by scales varied similarly after the onset of growth; however, during the pre‐growth period, fluctuations in glycine uptake may have reflected physiological changes that were not detected by measurement of scale and body growth, but did relate to feeding activity. Patterns of glycine uptake and scope for growth were positively correlated (r= 0.74, P<0.05), which suggested that uptake may be related to general nutritional state.
