Larimichthys polyactis is a transboundary migratory fish species targeted intensively by fisheries in China, Japan and South Korea, and it is currently subjected to substantial fishing pressure. Clarifying population delineation is critical for the sustainable management of overexploited fish stocks such as this species. For skeletal phenotypic analysis, we collected 30 adult specimens from each of six sampling stations in the...

Otolith Sr/Ca profiles are widely used to investigate early life migration and habitat use in both diadromous and oceanodromous fishes. This study focuses on Larimichthys polyactis , an oceanodromous species of significant ecological and commercial importance in East Asian waters. This study investigates the influence of environmental factors on the otolith Sr/Ca ratios during its early life stages (ELS). In Experiment A, we a...

Introduction The implementation of the 10-year fishing ban in the Yangtze River has provided a crucial opportunity for the recovery of rare and endangered diadromous species, such as Coilia nasus . Methods In this study, we utilized electronic length–frequency analysis (ELEFAN) and length-based Bayesian biomass estimation (LBB) method to fit the body length data of C. nasus from the Yangtze River Estuary and its adjacent sea a...

Small yellow croaker ( Larimichthys polyactis ), a commercially essential fish commonly caught in China and South Korea, is now facing a severe decline in resources. The recruitment and surplus of L. polyactis depend selecting a suitable marine environment for overwintering. However, the international overwintering migration habit of L. polyactis limits the investigation of its overwintering environment preferences and suitabl...

Larimichthys polyactis, a typically oceanodromous species found across the East China, Yellow, and Bohai Seas, is one of the most ecologically and commercially important species in East Asian countries. Moreover, over the past decades, L. polyactis has experienced significant changes in its biological characteristics under long-term intensive fishing pressure, suggesting a need for urgent protection. A robust understanding of...

Small yellow croaker Larimichthys polyactis is an important commercial fish species; however, industrial-scale fishing has largely contributed to the changes in its biological characteristics, such as individual miniaturization, faster growth, and younger average age. Robust understanding of the pivotal life history of L. polyactis , a typical oceanodromous species, is needed for its conservation and restoration. However, L. p...
