Tagging and Biological data for Grouper fished around St Helena Island collected from March 2019

The dataset is an excel file which compiles data on biological sampling and tagging activities. Biological sampling records: length, weight, sex, maturity, gonad weigth, latitude, longitude and depth caught for grouper (Ephinephelus adscensionis). Tagging records: length, tag ID, latitude, longitude and depth caught, time of release and presence or absence of barotrauma. The grouper were caught from St Helena's inshore waters from March 2019 in order to characterise seasonal reproductive patterns in the grouper ecology and establish a biomass estimate.
