The thermal characteristics of fresh antarctic krill were studied on board a ship of the coast of Wilkes Land, 64-65°S, 110-117°E, Antarctic Ocean, in January 1978.
The density, specific heat, and heat conductivity of fresh gravid females were measured immediately after the catch, the values 1.03×103 ?? 1.04×103 (kg/m3), 0.88 (kcal/kg•°C), and 0.64 (kcal/m•h•°C) were obtained.
The above data were found to be not very different from those measured on the frozen samples after storage for few months.
A temperature-time course curve of the krill body heated at 90°C was drawn for three different body sizes on the basis of the above figures for the thermal characteristics.
