Abstract: ABSTRACT The blackspotted croaker ( Protonibea diacanthus ) is among the highest‐valued commercial marine fish species in Bangladesh. Therefore, we assessed the stock status, economic significance, and market status of blackspotted croaker in the Bay of Bengal, Bangladesh. We estimated life history parameters and sustainability indicators to determine if the stock was being sustainably managed. Size of blackspotted croaker was significantly differ temporally. Blackspotted croaker increased in weight allometrically in relation to length. Length‐age life history parameters were L ∞ = 161.16 cm, k = 0.39 year −1 . Natural mortality M was 0.39 year −1 and fishing mortality F was 0.35 year −1 . Catch composition and sustainably indicators revealed that the stock was prone to recruitment and growth overfishing. Medium to large sized blackspotted croaker (> 85 cm) fetched the highest price in commercial markets for the swim bladders that was worth many times more than the value of fillets. The highest demand of swim bladders in export commerce termed this species as marine gold to the fishers. Therefore, fishers were increasingly motivated to target the species. Ununiformed landing of blackspotted croaker, for domestic and international trade of swim bladder of blackspotted croaker, and poorly documented trading supply chains make this fishing industry luck‐driven. Management interventions are needed to sustain the fishery and economic value.
