Abstract To understand status and impact of the nutrient on shellfish culture in the aquaculture area at Yangma Island(N 37.5°—37.7°,E 121.5°—121.9°)(semi-enclosed bay), Yantai, Shandong province, the concentration changes, spatial distribution, and limitation characteristics of dissolved inorganic nitrogen (DIN), reactive phosphate (PO₄-P), and silicate (SiO₃-Si) were analyzed in the seawater at 43 stations arranged in a grid, with a water depth of 10—18 m at this area in summer cruises in August from 2019 to 2024, in accordance with the sites-sampling principle of near-shore density and far-shore sparseness, and combined with the accessibility of raft breeding areas. The results showed that there was the average DIN concentration of (7.92±5.79) μmol/L, with continuous decrease and spatial distribution pattern of gradual decrease from the nearshore to the offshore areas. The average concentration of PO₄-P was found to be (0.174±0.130) μmol/L, continuous decrease and a spatial distribution pattern of lower values in the central area and high values around the periphery, thus forming a "central depression" deficiency zone in the middle of the aquaculture area. The average SiO₃-Si concentration of (11.60±3.58) μmol/L was decreased gradually from the nearshore to the offshore areas. The nutrient structure was characterized by a significant PO₄-P limitation, with median values of N/P ratio of 43.6 and Si/P ratio of 79.5, and the high-value zones primarily located in the central area of the aquaculture zone. Sharp declines in terrigenous nutrient inputs, and coupled with a rapid expansion of high-density farming of Pacific oysters Crassostrea gigas led to persistent nutrient depletion and a concomitant imbalance in phosphorus cycling. This dual mechanism imposes multi-pathway stress on oyster physiology, leading to reduce condition factor and to elevate mortality. The findings indicate that rational stocking-density control and scientifically quantified reductions in nitrogen and phosphorus discharge are essential for restoring the ecological integrity of aquaculture zones and for ensuring the sustainable development of mariculture.
