Rates of oxygen consumption of yellowfin sole (Limanda aspera (Pallas)) relative to body size, food intake, and temperature

Measurements of oxygen consumption rates were made for both fed and unfed yellowfin sole ( Limanda aspera (Pallas)) to examine the role of fish weight and temperature on respiration rate. At 5.5°C, VO 2 for unfed fish of 3 to 603 g was described by the equation: ml 0 2 ind −1 h −1 = 0.014 (wet wt. g) + 0.33: r 2 = 0.95. An increase in environmental temperature between 1.5 and 10°C resulted in a linear increase in rates of oxygen consumption. The relationship between temperature and VO 2 for 40- to 70-g unfed sole was μl 0 2 g −1 = 3.875(°C) + 4.023; r 2 = 0.99. After a single feeding of 1% or 3% of body weight, oxygen consumption rates increased about 38% over unfed rates.
