The status of fishery resources in the Yangtze estuary and its adjacent waters is still unclear for effective implementation management strategies. To help address this gap, a new method especially data-limited fish stocks (LBB) was applied to assess seven commercially ecotrophically important stocks. Fish specimens were collected by bottom trawling quarterly from May 2018 February 2019. Two historical datasets with same area Indian perch ( Jaydia lineata ) sickle pomfret Pampus echinogaster ). explore growth features resilience stocks, auximetric plots performance indices (Φ′) used.
