Stage-structured monitoring data for <i>Coilia nasus </i>in the lower Yangtze River
Listed in figshare
Description
<p dir="ltr">This dataset supports the manuscript “Stage-structured monitoring identifies a tidal freshwater nursery signal for Coilia nasus in the lower Yangtze River”.The dataset contains fixed-station monitoring records, environmental variables and otolith microchemistry data used to evaluate juvenile recruitment, large-bodied occurrence, tidal-range associations and life-history stage structure of long-jaw Coilia nasus in the Jingjiang tidal freshwater reach of the lower Yangtze River, China.
Fish were sampled with a standardised fixed trap net from 2002 to 2017. The monitoring series includes 519 effective surveys, 10,567 counted long-jaw C. nasus and 10,560 individuals with standard-length records.The files include catch and body-length records, sampling dates, monthly and daily environmental variables, otolith Sr/Ca profile data, derived life-history classifications and figure source data used in the revised analyses.

Juvenile Recruitment Index (JRI) was defined as the August–October catch of individuals <120 mm standard length per effective sampling event. Large-bodied CPUE (LBCPUE) was defined as the annual catch of individuals ≥180 mm standard length per effective sampling event. Otolith Sr/Ca profiles were used to distinguish freshwater records to capture from recorded estuarine/marine excursions.These data provide a stage-structured pre-moratorium baseline for assessing juvenile recruitment, large-bodied occurrence and hydrological context in future post-moratorium monitoring of C. nasus in the lower Yangtze River.</p>
