As an important commercial marine fish species for aquaculture in my country, the growth performance and survival rate of the spotted sea bass (Lateolabrax maculatus) depend heavily on the type of culture system and its capacity for environmental control. This paper reviews and compares the mechanisms by which pond culture, net-pen culture, and recirculating aquaculture systems (RAS) influence growth performance and survival rates. The results indicate significant differences among these systems regarding water quality stability, dissolved oxygen supply, ammonia-nitrogen accumulation, and stocking density management, leading to variations in growth rates and feed conversion ratios (FCR). Among them, RAS typically demonstrates superior growth efficiency and lower mortality due to robust water quality control and stable environmental conditions; pond systems are significantly affected by natural environmental fluctuations, resulting in less stable growth and survival; net-pen systems fall between the two but are susceptible to the effects of water exchange and seasonal changes. Comparative analysis further reveals that environmental stability and nutrient utilization efficiency are key determinants of aquaculture performance. Additionally, the incidence of disease and stress responses intensifies under high-density culture conditions. Based on this comparative analysis, the paper proposes optimized culture models and environmental management strategies to enhance the sustainability and productivity of spotted sea bass aquaculture.
