To explore the effects of different feeding patterns under cyclic starvation conditions in a land-based circular pond on biochemical indicators and aquaculture water quality of Channa argus. This experiment utilized a productive land-based circular pond (with a diameter of 8 meters) as the culture facility, setting up four experimental groups: periodic starvation for 1 day followed by feeding for 3 days (S1F3 group), periodic starvation for 1 day followed by feeding for 6 days (S1F6 group), periodic starvation for 1 day followed by feeding for 9 days (S1F9 group), and normal feeding (S0 group). The initial body weight of the Channa argus used in the experiment was 10.25 ± 0.32 g, and the experimental period was 60 days. The research results indicated that: (1) The TC and TG content in all experimental groups was lower than that in the S0 group, and with the extension of re-feeding time, the TC and TG content gradually increased, with the S1F9 group being the highest, followed by the S1F6 group. (2) From the perspective of liver tissue, the liver cell tissue of the S0 group was relatively complete, and the degree of vacuolation of liver cells in the experimental groups was more severe than that in the S0 group, with the highest vacuolation rate being in the S1F9 group, and the liver tissue of the S1F3 and S1F6 groups was the most severely compressed. (3) From the perspective of water quality, periodic starvation and re-feeding could improve water quality, and based on water quality evaluation, the S1F6 group had the highest water quality rating. In summary, periodic starvation and re-feeding could reduce the level of fat metabolism, leading to structural damage of liver cell tissue, while water quality is improved; among the experimental groups, the S1F6 group had the best water quality, with a smaller decrease in lipid metabolism levels and less liver cell damage.
