Abstract
Ontogenetic, seasonal, and sex-related patterns in energy density (J/g wet mass) was studied in burbot (Lota lota), lean lake trout (Salvelinus namaycush namaycush) and siscowet lake trout (Salvelinus namaycush siscowet) collected from Lake Superior in 1996 and 1997. Energy density was strongly negatively correlated with water content for all fishes (r2=0.86 to 0.99). For fishes of comparable size, energy density of siscowet (10.8 kJ/g) was significantly higher than lean lake trout (7.8 kJ/g) and both were significantly higher than burbot (5.1 kJ/g). Energy density in spring was higher in lean and siscowet lake trout, and lower in burbot than in other seasons. No significant differences were apparent between sexes within a species. Energy density increased in a predictable fashion with body mass for lean and siscowet lake trout, but varied without trend for burbot. The regression common to the three species (kJ/g wet mass = 36.78 0.41(% water), p < 0.001) provides a straightforward method for estimating ontogenetic and seasonal energy density in these fishes.
