Modified north west shelf fish traps were used to sample reef fishes at 40-45 m depth along the northern slope (flat habitat) and north-eastern slope (broken habitat) of Rib Reef and in two habitats of different rugosity on the back reef at Davies Reef. Sampling was carried out at Rib Reef between 23 April and 1 May, 1992 and at Davies Reef between 23 and 30 May, 1992.At both reefs, echo-sounding profiles (perpendicular to the reef crest) were run from shallow water (
本研究采用改良型西北大陆架渔笼（Modified north west shelf fish traps），于40~45米水深处，在里布礁（Rib Reef）北坡（平坦生境）、东北坡（破碎生境），以及戴维斯礁（Davies Reef）礁后区两种不同粗糙度的生境中开展礁区鱼类采样。采样工作分别于1992年4月23日至5月1日在里布礁实施，1992年5月23日至30日在戴维斯礁完成。两处礁体均布设了垂直于礁脊（reef crest）的回声测深剖面（echo-sounding profiles），测线起点为浅水区（
