Surveys on Neon Flying Squid by Squid Jigging in the High Sea of Northwest Pacific Ocean

Surveys conducted between 2021 and 2024 by R/V Songhang, Shanghai Ocean University's pelagic fishery resources survey vessel, revealed that the predominant squid species in the Northwest Pacific Ocean, which were Neon flying squid, Boreal clubhook squid, Boreopacific armhook squid, Clubhook squid and Luminous flying squid. Except for the neon flying squid, the other four squid species were bycatches for squid jigging. Catch data of R/V Songhang between 2021 and 2024 were mapped in this report to illustrate the fishery status. Basic Biological Characteristics of Neon flying squid, including the mantle length (ML) composition, body weight (BW) composition, ML-BW relationship, sexual maturity composition, and feeding ecology information were also detailed in this report. As China gradually improves and stabilizes the survey for NFS, the R/V Songhang's independent fisheries biology information will be provided as the basis for the NFS stock assessment.
