Nuclear power plants utilize great quantities of seawater to cool down, resulting in substantial warm water discharges that may affect nearby fisheries and marine ecosystems. This study focused on Crassostrea (Magallana) ariakensis, a commercially farmed oyster species along the southern coast China. To evaluate thermal impacts from nuclear plants, indoor simulations replicated seasonal temperature conditions near coastal facilities (26 °C spring autumn, 16 winter, 30 summer). We conducted tolerance static dynamic experiments, with 51-day long-term experiment suitable growth under different acclimation temperatures. The effects C. ariakensis were systematically assessed through survival, growth, digestibility, nutritional quality. results showed discomfort range was (48.6 ± 1.2)~(58.9 3.0) °C, critical maxima (CTM) value (51.6 1.4)~(61.2 2.2) incipient lethal (ILT50) 45.61 53.71 55.90 respectively; all these values increased gradually rise temperature. After increase 1 2 4 did not soft tissue wet weight, condition index, moisture content, fat content but amylase activity digestive gland decreased experimental groups. show influence physiological metabolism is limited. However, based normal habitat summer, caused by need be paid attention to.
