Abstract
In fiathead sole (Hippoglossoides elassodon) growth was linearly related to energy consumption (J g−1 day−1 ) at 4°C by the following equation: growth (%bw day−1) =0.006 (consumption J g−1 ) −0.130; r2 =0.80. Growth was independent of size for fish between 1 and 350g when growth was expressed as a function of consumption in Jg−1 day−1. Maintenance ration determined in feeding - growth experiments was 21.7 J g−1 day −1 at 4.0°C.
Minimum estimates for daily ration to achieve growth rates observed in the Bering Sea were ∼0.4 to 6.2%bw day−1, depending on fish size and prey energy content. These rations are three to 50 times higher than previous existing consumption estimates but well within the capacity of the species.
