Abstract: Currently, the East China Sea region is implementing the national "Blue Granary" strategic mission. A key compon-
ent of this mission is the scaling up and high-quality development of marine ranching, aiming to gradually replace highly
destructive traditional fishing practices in nearshore and offshore areas. However, a solely conservation-oriented model of mar-
ine ranching is insufficient, as it fails to accommodate the labor absorption and industrial restructuring required for the broader
transformation of the fisheries sector. Therefore, it is necessary to optimize and adjust the attributes of marine ranching in the
East China Sea region and expand and enhance its functions. One of the key steps in this process is the selection and construc-
tion of a target species system for marine ranching in the East China Sea region. To optimize the theoretical framework for mar-
ine ranching construction in the East China Sea region and enhance the targeted management efforts, this study takes the mar-
ine ranching in the northern Zhoushan archipelago waters as an example and employs the Analytic Hierarchy Process (AHP) to
comprehensively screen target species for marine ranching in this area. A hierarchical structure model was constructed, encom-
passing five rule layers: ecosystem status, population regulation function, resource utilization paradigm, economic contribution
intensity, and social impact capability, along with 15 specific indices such as energy flow contribution and ecological niche
width. Based on this model, the weights of the rule layers and index layers were determined through expert scoring. Represent-
ative fishery resource species in the study area were preliminarily screened based on resource abundance and economic value.
A total of 39 core target species for marine ranching were identified, including fish such as S. marmoratus and L. maculatus,
crabs like P. trituberculatus and C. japonica, cephalopods represented by S. maindroni and O. vulgaris, and shellfish including
M. unguiculatus and R. venosa. Based on this, utilization strategies for core target species were refined, establishing a harvest-
ing system centered on sea angling supplemented by gathering and net fishing. This identified sea angling target species like S.
marmoratus and C. myriaster, gathering target species like R. venosa and A. japonica, and net fishing target species like P.
argenteus and P. trituberculatus. The establishment of a target species selection system for marine ranching in the northern
archipelago waters of Zhoushan clarifies the specific objects and priority levels for marine ranch resource production in this
area. It identifies breakthrough strategies for developing marine ranches in the archipelago waters of the East China Sea, provid-
ing practical guidance for the development of marine ranches and fisheries management in the region.
