Field observations were conducted to analyze microhabitat use by damselfishes on a shallow coral moat (<3m, about 6ha) of Shiraho reef, Ishigaki Island, Okinawa, using digitalized aerial photographs processed with image analysis software as field maps. The color same as the benthic landscapes that were identical to exact microhabitats of a damselfish (anemonefish) were extracted from the photographs, which were recognized as the potential habitats of the fish. Geometrical features of the potential habitats were analyzed on a computer related to population density data of the fish. Similarly, all benthic landscapes used by damselfishes were extracted from the photographs, and features of their microhabitats with higher species richness and diversity of all damselfish species in study sites were analyzed.The potential habitats for the anemonefish were 3 dimensional reefs that could be recognized on the aerial photographs, and population density of the fish in a quadrat was correlated with total aria and total perimeter of the potential habitats in the quadrat. This suggests that the anemonefish are abundant in a place where 3 D reefs are aggregated. Damselfish species richness and abundance in a quadrat were also correlated to the total area of 3 D reefs in the quadrat. Total area of aggregated 3 D reefs that can be recognized on aerial photographs may be an effective indicator of high species richness and abundance in a shallow coral reef moat.

利用经图像分析软件处理的数字化航空照片作为野外地图，在冲绳石垣岛白穗礁的浅珊瑚护城河（<3 m，约6公顷）上进行了野外观察，分析了豆娘鱼对微栖息地的利用。从照片中提取出与雀鲷（海葵鱼）的确切微生境相同的底栖景观相同的颜色，这些照片被认为是鱼类的潜在栖息地。在计算机上分析了潜在栖息地的几何特征与鱼类种群密度数据。同样，从照片中提取了所有的底栖景观，并分析了研究地点所有雀鲷物种的物种丰富度和多样性较高的微生境特征，海葵鱼的潜在生境是三维礁，可以在航空照片上识别。样方内鱼类种群密度与样方内潜在生境的总面积和总周长相关。这表明，在三维珊瑚礁聚集的地方，海葵鱼是很丰富的.样方中雀鲷的物种丰富度和丰度也与样方中三维礁的总面积相关。可以在航空照片上识别的聚集的3D珊瑚礁的总面积可能是浅珊瑚礁护城河中高物种丰富度和丰度的有效指示器。
