Climate change has significant implications for raceway aquaculture, particularly through altered water temperatures and availability, making this the most relevant choice. As global temperatures rise, the water temperatures in raceways can also increase, which may lead to several consequences for fish health and growth. Fish are ectothermic organisms, meaning their metabolism is directly influenced by the surrounding water temperature. Elevated temperatures can enhance metabolic rates but may also lead to stress, reduced oxygen levels, and increased vulnerability to diseases.

Changes in precipitation patterns due to climate change can also affect water availability in raceways. Droughts may reduce water levels, while heavy rains can lead to runoff that may introduce pollutants or sediments, adversely impacting water quality. Both factors—temperature and availability—are crucial in maintaining optimal conditions for aquaculture species, affecting their growth rates, reproduction, and overall health.

In contrast, the other options do not reflect the realities of raceway aquaculture in relation to climate change. For instance, the idea that there would be an elimination of water management systems is misleading; in fact, effective water management becomes increasingly critical as climate-related changes occur. The notion of uniform water temperatures for all species fails to recognize the specific temperature preferences and tolerances of different aquaculture species, which can
