Metadata 1) Title : Thalassoma surveys 2) Abstract : Thalassoma surveys were conducted from 2003200 7, 2009 and again in 2012. These surveys were conducted at each of the 192 reefs, and in 2012 on 198 reefs at the 12 sites that are sampled every year to every few years These reefs are characterized in the reef morphology section. Thalassoma surveys are meant to characterize size structure of Thalassoma and other fish species thought to affect Thalassoma dynamics. We ultimately hope to use the data on size structure and numbers of Thalassoma to infer settlement rates, growth rates and survival.

Updated 5/2/12 9:19 AM LabridScarid Surveys on the Long Term Reefs Title: Thalassoma Surveys on Long Term Reefs Overview : Characterize size structure of Thalassoma hardwicke and other fish species dominant around the reefs We ultimately hope to use the data on size structure and numbers of T halassoma to infer settlement rates, growth rates and survival. General Procedure: A single snorkeler approaches one of the 22 patch reefs ( for size of reef, see LTR_PhysicalChar file s, each are ~ 18 m2 in aerial extent ) swam around it and attempted to recognize and estimate the size of all the Thalassoma on the reef. L arge adults that were clearly attracted by the arrival of the snorkeler were ignored. We also estimated the number and size of resident Gomphosus varius P seudocheilinus lineatus all arou nd the reef. Counts of small recruits of labrids and scarids were combined, excluding those three species. We also counted and identified species that we considered potential predators that were within ~ 3 m eters of the reef for each patch reef. In 2012 settler counts were not completed Materials: Data slate with photographs of Th alassoma of different size classes to help with the visual estimates at each site. Solutions/Reagents (if applicable): NA Procedure: See above Calculations: Note: data were entered into excel and then restructured with a macro to create the final data set. Because of this data entry method there maybe two similar entries. ( e.g., if there were two fish of species or type X that were the same size (Y), they would each be on the final data sheet as Fish X, Size Y, count: 1, instead of Fish X and Y size count: 2) Author: Primary Author : Anya Brown September 2013
