To analyze the reef-tending behavior and spatial distribution of rocky reef fishes under different aperture shapes and sizes, the behavioral effects of artificial reefs with different aperture shapes (diamond, circle, square) and sizes (2.5, 5, 7.5, 10 cm) on juvenile Acanthopagrus latus were observed and analyzed. LoliTtrack Version 5 was used to analyze the mean velocity, mean acceleration, mean turning speed, percentage of activity time, and mean distribution coordinate position of juvenile A. latus. The results showed that there was a significant increase in the mean distribution rate of juvenile A. latus in the reef area after being placed in the artificial reef, and the juveniles had the highest mean distribution rate at (27.32±4.93)% in the artificial reef area in the diamond opening experimental group, followed by the square and circular opening experimental groups, which had rates of (25.48±3.41)% and (19.83±5.59)%, respectively. In addition, the highest mean distribution rate of A. latus juveniles in Zone VI was found in the experimental group with 7.50 cm openings at (29.18±4.75)%; the second highest mean distribution rate in Zone VI was found in the experimental groups with 2.50 cm and 5.00 cm openings at (23.45±3.86)% and (23.04±5.51)%, respectively; and the lowest mean distribution rate was found in the group with 10.00 cm openings at (21.17±4.93)%; followed by square and round openings at (25.48±3.41)% and (19.83±5.59)%, respectively. was the lowest with (21.17±5.14)%. In terms of locomotor ability, the mean speed, mean acceleration and percentage of activity time of juvenile A. latus showed highly significant differences between the experimental group of the artificial reef model and the blank control group, with the mean speed increasing from (1.12±0.34) m/s in the blank control group to (1.53±0.64) m/s; mean acceleration increasing from (29.54±9.51) m/s in the control group to (40.47±17.53) m/s; and percentage of active time increasing from (77.13±12.66)% in the blank control group to (83.36±12.40)%. The mean speed, mean acceleration, mean turning speed, and percentage of activity time of juvenile A. latus differed significantly among the reef model treatment groups. The lowest mean velocity, mean acceleration, and percentage of active time were (0.81±0.31) m/s, (20.85±8.38) m/s² , and (67.44±17.45)%, respectively, for the reef model with a diamond-shaped opening and 7.5 cm opening size, which was the least active; whereas the highest mean turning speed was found in (56.79±22.80) deg/s. No significant difference was found in the mean distribution coordinate positions. The study showed that after adding the artificial reef model, the A. latus larvae had the greatest mean distribution rate as well as the lowest degree of activity for the reef model with a diamond-shaped opening and an opening size of 7.50 cm and that this artificial reef model was the most effective in attracting A. latus larvae. This preliminary study investigated changes in the reefing behavior of juvenile A. latus on different types of reefs. The results of this study can provide a theoretical basis and reference for the selection and design of species-specific proliferating artificial reefs.
