Mantle length composition and length-weight relationships of neon flying squid by Chinese squid jigging vessels between 2011 and 2025

This study analyzes the biological data of 10,061 neon flying squid (Ommastrephes bartramii) specimens collected by Chinese jigging vessels in the North Pacific Ocean from 2011 to 2025. The report focused on mantle length (ML) composition and length-weight (ML-BW) relationships to discern differences between regional cohorts and their long-term growth trajectories. The biological data of neon flying squid provided by Chinese squid fishing vessels are expected to provide complementary information for NFS stock assessment.
