Abstract： This study investigates the structure，assembly，economic benefits and associated challenges of the multi-anchor roped stow net utilized around Ant Island，in the Putuo District， Zhoushan. The following conclusions were drawn：（1） The Multi-anchor roped stow net，an improvement on the traditional single-piece stow net，utilizes floating sinkers for vertical expansion and multiple anchors for horizontal stability，with four cod-ends in each panel. This structural innovation classifies it as a multi-anchor roped stow net. （2） The primary， species caught includes Parapenaeopsis hardwickii， Oratosquilla oratoria ， Collichthys lucidus Coilia m ystus， Harpodon nehereus，and Portunus trituberculatus. （3） The fishing gear and method is distinguished by its operational simplicity，high catch freshness due to proximity to shore，and compatibility with family-oriented fishing practices，allowing fishers to balance economic returns with familial responsibilities by returning every 2～3 days.（4） The fishing gear primarily relies on water currents to guide fish into the net，minimizing disturbance to the seabed and thereby promoting environmental sustainability.（5） Nonetheless，incidental capture of juvenile fish of commercially valuable species presents a potential challenge to resource sustainability. To mitigate this，it is recommended to increase the cod-end mesh size to 35mm ，reducing bycatch of juvenile fish and supporting long-term sustainable fishery management. This study offers insights for optimizing fishing gear design to enhance economic eficiency while promoting environmental stewardship in coastal fisheries.
