: Squid samples were randomly selected from fisheries catch taken by Chinese trawler fleets. Thus, the samples are part of the fisheries catch (with specimens being already dead when sampled). The samples were taken with permission from Shanghai Ocean University, which is in charge of oceanic fisheries research in China (Hu et al. CitationRef removed). The sampling protocol had been evaluated and approved by Shanghai Ocean University. The samples were taken strictly following the protocol. The sampled squid catch (dead squid) were frozen and then dissected in the laboratory. We confirm that the fisheries from which the squid were obtained were conducted by a legitimate Chinese company with appropriate permits to fish in the waters described in the paper. We also confirm that none of the squid was collected for the purpose of this study. They were caught as fisheries catch.
