SPC PROCFish/C Fish Observations Tuvalu 2004-2005

Coastal fish species of commercial interest observed on Underwater Visual Census transects in Tuvalu during the PROCFish/C surveys (2004-2005) in 4 sites Funafuti, Niutao, Nukufetau and Vaitupu. The individual counts correspond to the observations by a single diver (one side) on the 50 m transect, from the transect line up to visibility (distance sampling).本数据集收录了2004-2005年PROCFish/C调查期间，在图瓦卢富纳富提、纽陶、努库费陶与瓦伊图普4个站点的水下视觉普查（Underwater Visual Census）样带上观测到的具有商业价值的沿岸鱼类物种。个体计数结果对应于单次潜水员单侧开展观测时，在50米样带上从样带线至可视范围内的观测数据，该观测采用距离抽样（distance sampling）法。
