: Specimens were collected as dead squids from the commercial jigging fisheries landings, during the fishing season between 2017 and 2020. The specimens were analyzed in the laboratory using methods that are in line with current Chinese national standards, namely Laboratory Animals-General Requirements for Animal Experiment (GB/T 35823–2018). As all material sampled in this work was obtained from commercial jigging fisheries landings and already dead, there was no requirement for ethical approval of sampling protocols as it did not include live organisms.
