Oysters followed a similar growth pattern, with their shell growth rate increasing from 0.0616 \(\pm\) 0.0115 mm/day under limited food conditions to 0.2548 \(\pm\) 0.0279 mm/day when food was plentiful. The specific growth rate for oysters also showed a substantial rise, ranging from 0.5608 \(\pm\) 0.0856 mm/day at low food levels to 2.2855 \(\pm\) 0.2169 mm/day under the optimal feeding conditions. These findings highlight the crucial role of food availability in enhancing the growth rates of mussels and oysters. Moreover, these findings underscore the importance of food availability in mediating the impact of temperature on the growth of these bivalves, with higher food levels significantly enhancing the growth rates in both species. Additionally, the highest condition index and meat yield in the queen scallops were observed under an increased temperature, indicating an overall improvement in their physiological condition and tissue development despite the reduced weight gain. The elevated adductor, gonadosomatic, and hepatosomatic indices further suggest that thermal conditions favor the development of key tissues, such as muscle and reproductive organs. This may be due to enhanced metabolic activity at higher temperatures, which can accelerate physiological processes and promote energy allocation to critical functions like reproduction and muscle maintenance [17; 33; 36; 49]. However, the long-term sustainability of these benefits under continued thermal stress requires further investigation, as prolonged exposure to elevated temperatures may lead to metabolic imbalances or exhaustion of energy reserves [23; 31; 32]. These findings are consistent with prior research showing that moderate temperature increases can enhance physiological performance in marine bivalves within a certain thermal threshold. Conversely, in another study conducted on two species of mussels (_Mytilus edulis_ and _M. galloprovincialis_) and oysters (_Crassostrea gigas_ and _Ostrea edulis_), it was noticed that the condition index was higher when the food concentrations were increased and decreased with increasing temperature [23]. Furthermore, [PERSON]'s 2022 study demonstrated that mussels and oysters exhibited high survival rates when they were exposed to elevated temperatures ranging from 3 to 19 \({}^{\circ}\)C, with survival rates from 93 to 100%. Additionally, [PERSON] et al. [18] conducted a notable study investigating how a rise in temperature may have contributed to the dramatic decline in bay scallop (_Argopecten irradians_) harvests in the Cape Cod region of northeastern USA, where catchesplummed by 98% between 2019 and 2021. This comprehensive study utilized a combination of fishery data, environmental monitoring, and both field and laboratory experiments to uncover the effects of climate-driven coastal warming in Nantucket Harbour and Nantucket Sound, where temperatures increased by 2.48 and 3.42 \({}^{\circ}\)C between 2003 and 2020, respectively. These researchers found that the interaction of warming and hypoxia, rather than hypoxia alone, led to significant scallop mortality. Laboratory simulations mimicking these environmental conditions confirmed the field data, revealing that a combination of warming and low oxygen was 9.4 times more lethal to scallops than hypoxia, 57.4 times more lethal than elevated temperatures, and 119.7 times more deadly than conditions with normal oxygen levels and no warming. Overall, these results underscore the severe biological impacts of warming and hypoxia on marine molluscs, as both factors disrupt the energy availability necessary for growth and reproduction, ultimately leading to high mortality rates [31]. Considering these findings, queen scallops emerge as a promising alternative for aquaculture under climate change pressures given their faster growth rates and broader environmental tolerance compared to mussels and oysters. Queen scallops can adapt to warmer and cooler waters, thus being more resilient to the temperature fluctuations associated with global warming [31].
