영문초록

This study was conducted to examine preference of abalone according to artificial reef shapes, materials and change of water temperatures for seeking artificial reef shape and characteristics of abalone movement. Physical factors were restricted to artificial reef shapes (rectangle, circle and triangle), materials (porus cement mortar, cement mortar), water temperatures (10, 15 and 20℃) and focused on the characteristics of abalone movement when they seek the suitable artificial reef shapes and materials. A series of experiments were conducted in a recirculation aquaculture system with dimensions of 2100×1000×1100 mm. 30 abalones (sizes: 3.3 ± 5.1 g) were used for each experiment. The experiments were replicated 3 times at (10, 15 and 20℃) The preference artificial reef shapes, materials and characteristics of abalone movement were observed using video (24 hours) and naked eye (12 hours three times Am09:00, Pm13:30, Pm18:00) a day) The data were evaluated by an analysis of variance (ANOVA). Behavior analysis was analyzed through observation log and video. It was observed that The numbers of abalones attracted porus cement mortar than cement mortar. At 10°C, they clustered in cement by a margin of 0.8 times, but at 15°C they clustered in porous cement by a margin of 2.8 times and a difference of 4.2 times at 20°C. also attracted triangle hole shape than circle and rectangle hole shape. The moving distance (avg. 1.35 m) and speed (avg. 0.033 10-3 m/s) of abalone showed highest activity at water temperature at 15℃.
