Siargao Island Protected Landscape and Seascape (SIPLAS) has an extensive mangrove area that supports marine biodiversity. This study documented mangrove fishes in three selected sites using a fishery-dependent survey approach, with samples taken by commissioned fishing or landed catch by local fishermen. A total of 129 species belonging to 38 families were documented and identified in the study. Dapa had the highest species richness with 70 species (54.26%), followed by Santa Monica with 63 species (48.84%), and San Benito with 28 species (21.71%). Eighty-four species (65.11%) were recorded as 'target' or economically significant, 39 (30.23%) were 'major species' or fishes that are not commercially valuable, while six (4.65%) were identified as 'indicator species' or species with ecological importance. The high fish species richness recorded for commercially important families, i.e., Haemulidae, Acanthuridae, Serranidae, Lethrinidae, Lutjanidae, and other target species indicate mangrove resilience to support these species. Six species (Balistoides viridescens, Chaetodon auriga, Chaetodon kleinii, Chaetodon lunulatus, Chaetodon octofasciatus, and Chaetodon ulietensis) were identified as ecologically important and native in the area. Juvenile fishes of coral reef species were recorded, such as Naso spp., C. auriga, Hemigymnus melapterus, Arothron spp., Naso vlamingi, Hemigymnus melapterus and Scolopsis margaritifera. Apart from these juveniles, the rest of the species observed are usually found on coral reefs, such as commercially significant threadfins, trevallies, queenfish, snappers, and groupers, which are all considered major migratory species. Findings of this study will undoubtedly supplement important data of SIPLAS for more conservation efforts (e.g. designation as Ramsar Site).

锡亚高岛受保护的景观和海景 (SIPLAS) 拥有广阔的红树林区，支持海洋生物多样性。这项研究使用依赖渔业的调查方法记录了三个选定地点的红树林鱼类，样本由委托捕鱼或当地渔民上岸捕获。该研究共记录和鉴定了属于 38 个科的 129 个物种。达帕物种丰富度最高，有70种（54.26%），其次是圣莫尼卡，有63种（48.84%），圣贝尼托有28种（21.71%）。84 个物种（65.11%）被记录为“目标”或具有经济意义，39 个（30.23%）是“主要物种”或没有商业价值的鱼类，而 6 个（4.65%）被确定为“指标物种”或具有生态重要性的物种。商业上重要的科，即 Haemulidae、Acanthuridae、Serranidae、Lethrinidae、Lutjanidae 和其他目标物种记录的高鱼类物种丰富度表明红树林具有支持这些物种的复原力。六种（Balistoides viridescens、Chaetodon auriga、Chaetodon kleinii、Chaetodon lunulatus、Chaetodon octofasciatus和Chaetodon ulietensis）被确定为该地区的生态重要和原生动物。记录了珊瑚礁物种的幼鱼，例如Naso spp.、C. auriga、Hemigymnus melapterus、Arothron spp.、Naso vlamingi、Hemigymnus melapterus和Scolopsis margaritifera. 除了这些幼鱼外，观察到的其他物种通常在珊瑚礁上发现，例如具有商业价值的鲹鱼、鲹鱼、皇后鱼、鲷鱼和石斑鱼，它们都被认为是主要的迁徙物种。这项研究的结果无疑将补充 SIPLAS 的重要数据，以进行更多的保护工作（例如指定为拉姆萨尔遗址）。
