in calories. They respire and excrete substances measured in calories as well. If the
ingested calories exceed the calories excreted and respired, the fish will gain
weight. If ingestion is smaller, the average size declines. The excess calories are
converted to grams of flesh at different rates and the conversion efficiency declines
as the fish grows larger. The conversion efficiencies for small and large fish, G
SIZES and G SIZEL, are shown in Figs. 36.3 and 36.4.
