Puerto Rico Long-Term Coral Reef Monitoring Program Database Compilation

The Puerto Rico Long-Term Coral Reef Monitoring Program (PRCRMP) database compilation includes raw biological data (by transect) from reef locations around the Puerto Rican archipelago. Substrate cover by sessile-benthic categories and fish, and motile megabenthic invertebrate taxonomic composition and densities have been characterized in these stations, with variable sampling event frequencies between 1999 to 2021. At present, 42 permanent stations are surveyed biannually (21 per year). For the benthic characterization, a set of five 10-meter-long permanent transects are surveyed at each station. Sessile-benthic reef communities are characterized by the continuous intercept chain-link method, following the Caribbean Coastal Marine Productivity (CARICOMP) (1994) protocol. Demersal diurnal non-cryptic reef fish populations and motile megabenthic invertebrates are surveyed by sets of five 10 x 3 meters wide (30 m2) belt-transects centered along the reference line of transects used for sessile-benthic characterizations at each reef station. From 2004-2013, a diver completed an Active Search Census (ASEC) survey for 30 minutes annotating sizes and abundances of fish and macroinvertebrate species of interest. From 2015, the ASEC survey methodology was replaced by 20 x 3 meters (60 m2) band transects to identify commercially and ecologically important fish and megabenthic invertebrate species. Upon completion of the 10 meters belt-transect survey, the diver swims along the same depth and physiographic reef zone for an extra 10 meters to complete the 60 m2 transect. For each fish individual within the ASEC survey (2004-2013) and 60m2 band transects (2015-2021), a visual fork length (FL) estimate in centimeters is recorded. Fish length estimations are provided by the median of 5cm interval size classes. The cephalothorax length (measurement from the tip of the rostrum to end of the thorax), also known as carapace length (CL) in centimeters is used to report the size of lobsters (Panulirus spp., Scyllarides spp.) within belt-transects. Queen conch (Lobatus gigas) length is reported as the total (diagonal) shell length in centimeters. With the length-weight relationship information available in FishBase.org, biomass estimates are calculated for a subset of commercially and ecologically important fish species. The PRCRMP database was made possible with support from the National Oceanic and Atmospheric Administrations Coral Reef Conservation Program.

波多黎各长期珊瑚礁监测计划（PRCRMP）数据库的编纂包括了来自波多黎各群岛周围珊瑚礁地点的原始生物数据（按横断面收集）。在这些监测站中，对固定底栖生物类别、鱼类以及可移动大型底栖无脊椎动物的分类组成和密度进行了描述，采样事件的频率在1999年至2021年之间有所变化。目前，共有42个永久监测站每半年进行一次调查（每年21次）。针对底栖生物特征描述，每个监测站均使用一套五个10米长的永久性横断面进行监测。固定底栖珊瑚群落通过连续截取链环法进行特征描述，遵循加勒比海岸海洋生产力（CARICOMP）协议（1994年）。通过使用一系列五个10 x 3米宽（30平方米）的带状横断面，调查了每个珊瑚站点的底栖生物特征。从2004年到2013年，潜水员进行了为期30分钟的活跃搜索人口普查（ASEC）调查，记录了感兴趣鱼类和大型无脊椎动物物种的大小和丰度。从2015年起，ASEC调查方法被20 x 3米（60平方米）的带状横断面所取代，以识别商业和生态上具有重要意义的鱼类和大型底栖无脊椎动物物种。完成10米带状横断面调查后，潜水员沿着同一深度和地貌礁区再游进额外10米，以完成60平方米的横断面。对于ASEC调查（2004-2013年）和60平方米带状横断面（2015-2021年）中的每条鱼类个体，记录了厘米级的视觉叉长（FL）估计值。鱼类长度估计是通过5厘米间隔大小等级的中值提供的。头胸甲长度（从吻端到胸甲末端的测量），也称为甲壳类（Panulirus spp.，Scyllarides spp.）的甲壳长度（CL），以厘米为单位报告了带状横断面中龙虾的大小。女王螺（Lobatus gigas）的长度报告为总（对角线）壳长，以厘米为单位。利用FishBase.org中可用的长度-重量关系信息，对商业和生态上具有重要意义的鱼类物种进行了生物量估计。PRCRMP数据库的编纂得到了国家海洋和大气管理局珊瑚礁保护计划的资助。
