applied cautiously for cephalopod surveys. The results show that when the station design is well-matched with the spatial
distribution of various groups, survey accuracy can be significantly improved. The optimal station design depended on both
time and the number of stations deployed. When the requirement is to deploy 9 stations, we advise implementing the D4 plan
for conducting fishery resource surveys during the autumn voyage. For the spring season, no specific recommendation is made,
as the optimal station design fluctuates among different species groups. However, when deploying either 12 or 15 stations, the
D6 plan emerges as the preferred option for investigating the resource density of the four species groups in both spring and
autumn, as its design is intended to maximize benefits. This study can provide a valuable reference for optimizing sampling
designs in aquatic germplasm resource conservation areas.
