Growth and respiration were measured in a species of Anonchus (Nematoda: Plectidae) at 5Â°C, 10Â°C, 15Â°C, 20Â°C and 25Â°C. At 5Â°C no growth was measurable but the organisms remained active. Maximum production occurred at 15Â°C, but the highest rate of growth occurred at 20Â°C. Thus, adult size attained is dependent on the temperature of growth. Respiratory energy losses derived from Cartesian diver microrespirometry, increased with temperature up to 25Â°C. Regression coefficients (b values) derived from a log log linear regression of weight against oxygen consumption varied between 0.574-1.793, the lowest value being attained at 5Â°C, the highest at 20Â°C. Based on Q10, production and respiratory energy losses the optimum temperatures for Anonchus appears to lie between 10Â°C-15Â°C. Â© 1979 Springer-Verlag.
