| Lineage | Grouper were biologically sampled in either the EMD laboratory or at the fish processing facility. Fish were individually weighed in Kg with an accuracy of three decimal places, measured by total length (TL) to the nearest cm rounding down. Maturity was assessed using a five stage scale. The gonads were extracted by cutting open the stomach cavity which runs from the anus to the head and removing the internal organs. Gonads were weighed in grams to two decimal places. Otoliths were extracted by cutting into the head or accessed via the gill cover. Data is entered into a excell spreadsheet capturing latitude and longitude and the depth and biological data (length, total weight, sex and maturity, otolith, gonad weight). The entered data is checked by a second member of the EMD staff for quality control. Data collected was used to produce age/ length/ weight charts. Note that this data series links to two other data series (‘fisheries database 2015 and onwards’ and ‘Grouper gonad pictures’). |
