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...
