Description

Methods & Sampling

A. pisonii reproductive season. Crabs were immediately placed on dry ice and stored at -80^oC until dissection at which time the size and gut-width were determined and the whole egg clutch was carefully removed from the pleopods and dried to constant weight at 60-70^oC.

We pelletized a subset of the egg cultch and used a Parr semi micro bomb calorimeter to determine the energy content of the eggs (kJ/g) per the manufacturers instructions

The mass of the sample that was successfully combusted was calculated by first subtracting the mass of the sample dish before calorimetry from the mass of the sample dish after calorimetry. This value, the un-combusted sample, was then subtracted from the mass of the pelletized eggs.

The energy content of the combusted sample was calculated using the rise in temperature during calorimetry, the fuse correction, the W correction factor for the bomb, and the mass of the combusted sample following manufacturer instructions.
