To evaluate the optimal time for extracting lipids from the viscera of the common squid Todarodes pacificus the
proximate and fatty acid compositions of the liver and gonads of commercial squid were analyzed according to sex
for 6 months (Jul. to Sept. and Nov. to Jan.). The body and liver weights of the squid were larger in females than in
males, and were larger from Nov. to Jan. than from Jul. to Sept. in both sexes. The average lipid contents in the livers
of female and male squid were also higher from Nov. to Jan (22.9% and 24.9%, respectively) than from Jul. to
Sept. (11.7% and 17.5%, respectively). The average lipid contents of the ovaries and testes were 5.16% and 1.76%,
respectively, and changed little over the 6 months. The percentage of n-3 polyunsaturated fatty acids (eicosapentaenoic
acid + docosahexaenoic acid) was higher in the gonads (44.8-49.1%) than in the liver (36.3-37.6%). These
results suggest that Nov. to Jan. is the best time to extract lipids from the liver, whereas there was no difference in
the efficacy of lipid extraction from the gonads between the two seasons.
