Overview of the average energy density of Southern Ocean squid species

Season	Location	n	Body length (mm)	Water content (%)	Mean energy density		Method	Source
					kJ g−1 WW	kJ g−1 DW
Doryteuthis gahi
				80.9	3.09a	16.18	PC	Pandit and Magar (1972)
	Patagonia	8	60–90	76.6	4.95	21.16	BC	Ciancio et al. (2007)
Moroteuthis ingens
Summer	Possession Island	1		76.0	5.6b	23.51b	BC	Cherel and Ridoux (1992)
	New Zealand	6	356	80.3	4.73 c	24.02 c	PC	Vlieg (1984)
Illex argentinus
	Patagonia	4	210–415	76.7	5.01	21.52	BC	Ciancio et al. (2007)

In the ‘method’ column the method used for energetic value determination is indicated, where BC is bomb calorimetry and PC is proximate composition. Energetic values in italics represent values that were converted using the energetic values, wet weights and dry weights from the given source. n represents the number of samples measured

^aBased on measurements of water content, lipids (× 39.7 kJ g⁻¹) and crude protein

^bMantle and tentacles
