Reef fish visual surveys at La Parguera, and Mona Island Puerto Rico, 2004-2017

Data collected during two sampling periods, 2004-2006, and 2017 via underwater 10min, 30 x 2m transects on SCUBA at resampled locations in La Parguera, Puerto Rico and Mona Island, Puerto Rico. During these surveys, all reef fish except <i>Gobiidae</i>, <i>Blenniidae, </i>and <i>Stegastes partitus </i>were sampled. Column definitions are as follows:<br><b>ID</b> - Identifier column with transect, survey method, sampling time, year<b>Transect - </b>Transect number<b>Lat</b> - Latitude<b>Long - Longitude</b><b>Method - Sampling method (i.e. roving / belt transect)</b><b>Site - Experimental sampling site</b><b>Depth - Depth in meters</b><b>Zone - Experimental sampling zone (geomorphological)</b><b>Date - Date of sampling</b><b>Time</b> - sampling bout within each year<b>Season</b> - Numerical seaon (eg. Winter = 1, Spring = 2, etc)<b>_Period</b>- Experimental sampling period ( La parguera: Before = 2004-2006, After = 2017. Mona: 2005, 2010, 2017)<b>Surveyor</b> - Diver who collected data<b>Family</b> - Taxonomic family<b>Genus</b> - Taxonomic genus<b>Species</b>- species<b>Trophic</b> - Trophic abbrevation (eg. P = piscivore, H = Herbivore, SI = Sessile invertivore, MI = Mobile invertivore, Z = Zooplanktivore)<b>Code</b> - First letter of genus, first 3 letters of species<b>rov_spp_shared_2005</b> - species shared in roving counts conducted at Mona in 2005and 2017. S- Shared , NS - notshared, tran_shared - transect (ie notapplicable)<b>a</b> - species-specific length-weight parameter<b>b</b> - species-specific length-weight parameter<b>code_size</b> - species code + size class (ie. S1 = 0-5cm, S2 = 5-10cm, S3 = 10-15cm,S4 = 15-20cm, S5 = 20-25cm, S6 = 25-30cm, S7 = 30-35cm, S8 &gt; 35cm)<b>n</b> - number of fish (counts summed by species)<b>size_class</b> - fork length in cm<b>weight_g </b>- weight of individual fish in grams<b>m2</b> - area of belt transect (eg. 60m² in 2017 + 2005 at Mona, 100m² in 2004-2006 LP)<b>ind_m2</b> - density of fish standardized per meter-squared (relevant for LP comparisons)<b>biomass_m2</b> - biomass (g) standardized per-meter-squared<b>total_n</b> - total number of fish summed by survey ID (per transect, method, time, year)<b>total_bm </b>- total grams of fish biomass summed by survey ID<b>total_ind_m2</b> - total density of all fish per meter-squared
