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 Gobiidae, Blenniidae, and Stegastes partitus were sampled. Column definitions are as follows: ID - Identifier column with transect, survey method, sampling time, yearTransect - Transect numberLat - LatitudeLong - LongitudeMethod - Sampling method (i.e. roving / belt transect)Site - Experimental sampling siteDepth - Depth in metersZone - Experimental sampling zone (geomorphological)Date - Date of samplingTime - sampling bout within each yearSeason - Numerical seaon (eg. Winter = 1, Spring = 2, etc)Period - Experimental sampling period ( La parguera: Before = 2004-2006, After = 2017. Mona: 2005, 2010, 2017)Surveyor - Diver who collected dataFamily - Taxonomic familyGenus - Taxonomic genusSpecies- speciesTrophic - Trophic abbrevation (eg. P = piscivore, H = Herbivore, SI = Sessile invertivore, MI = Mobile invertivore, Z = Zooplanktivore)Code - First letter of genus, first 3 letters of speciesrov_spp_shared_2005 - species shared in roving counts conducted at Mona in 2005and 2017. S- Shared , NS - notshared, tran_shared - transect (ie notapplicable)a - species-specific length-weight parameterb - species-specific length-weight parametercode_size - 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 > 35cm)n - number of fish (counts summed by species)size_class - fork length in cmweight_g - weight of individual fish in gramsm2 - area of belt transect (eg. 60m2 in 2017 + 2005 at Mona, 100m2 in 2004-2006 LP)ind_m2 - density of fish standardized per meter-squared (relevant for LP comparisons)biomass_m2 - biomass (g) standardized per-meter-squaredtotal_n - total number of fish summed by survey ID (per transect, method, time, year)total_bm - total grams of fish biomass summed by survey IDtotal_ind_m2 - total density of all fish per meter-squared
