Pacific Reef Assessment and Monitoring Program: Rapid Ecological Assessments of Fish Belt Transect Surveys (BLT) at Coral Reef Sites across the Pacific Ocean from 2000 to 2009

Belt transects (BLT) is one of the non-invasive underwater-survey methods to enumerate the diverse components of diurnally active shallow-water reef fish assemblages. At each REA survey sites, BLT fish surveys are conducted along 3 consecutively-placed, 25m transect lines to quantify relatively small-bodied and abundant fishes. A pair of scuba diver-observers conducts parallel swims along the t...

Belt横断面（BLT）是评估日间活跃的浅水珊瑚礁鱼类群多样性的非侵入性水下调查方法之一。在每次REA调查站点，通过沿放置连续的25米横断面线进行Belt鱼类调查，以量化相对体型较小且数量众多的鱼类。一对潜水观察员并行游泳于横断面线，进行同步观测。
