Reef shark prey abundances from 46 sites in the Solomon Islands (2015)

Stereo diver operated video (stereo-DOV) were deployed at 46 sites occurring between October 17 and November 1, 2015, in four main locations: western Kolombangara Island (Kolombangara), north-western Parara and Gizo islands (Parara/Gizo), southern Vangunu Island (Vangunu), and eastern Gatokae and adjacent smaller islands Gatokae) in the Western Province, Solomon Islands. At each site six 5 m by 50 m belt transects separated by 10 m were completed at depths between 8 and 12 m
To calculate prey biomass, fish families that were known to be the prey of reef sharks were extracted from the stereo-DOV data and included: Acanthuridae, Balistidae, Carangidae, Chaetodontidae, Haemulidae, Holocentridae, Labridae, Lethrinidae, Monacanthidae, Mullidae, Pomacentridae, Scaridae, Scombridae and Zanclidae [4447]. Fishes of all sizes were included in calculations of prey biomass, as 99.5% were below 50 cm in length and therefore likely to be predated upon
These surveys were conducted in the customary waters of tribes on Kolombangara, Parara, Gatokae and Vangunu islands. The authors of the cited publication acknowledge the authority of leaders at each site who approved this work and thank them for their support

立体潜水员操作视频系统（stereo-DOV）于2015年10月17日至11月1日期间，在46个调查站点开展部署，站点分布于所罗门群岛西部省的四个主要区域：科隆班加拉岛西侧（科隆班加拉）、帕拉拉与吉佐群岛西北侧（帕拉拉/吉佐）、万努努岛南侧（万努努），以及加托卡埃岛东侧及毗邻小型岛屿（加托卡埃）。每个站点均设置6条间隔10米的5米×50米带形样带，作业水深介于8至12米之间。
为计算猎物生物量，研究人员从stereo-DOV采集的数据中提取了已知为礁鲨猎物的鱼类类群，涵盖刺尾鱼科（Acanthuridae）、鳞鲀科（Balistidae）、鲹科（Carangidae）、蝴蝶鱼科（Chaetodontidae）、石鲈科（Haemulidae）、金鳞鱼科（Holocentridae）、隆头鱼科（Labridae）、裸颊鲷科（Lethrinidae）、单角鲀科（Monacanthidae）、羊鱼科（Mullidae）、雀鲷科（Pomacentridae）、鹦嘴鱼科（Scaridae）、鲭科（Scombridae）以及镰鱼科（Zanclidae）[4447]。所有体型规格的鱼类均被纳入猎物生物量计算范畴，因其中99.5%的个体体长不足50厘米，大概率会成为礁鲨的捕食对象。
本次调查在科隆班加拉、帕拉拉、加托卡埃及万努努岛各部落的传统海域开展。相关研究论文的作者对各站点批准本次工作的部落首领致以敬意，并感谢其提供的支持。
