To ensure the international fin trade does not threaten their populations, several species have been listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix II. However, the lack of data on fin\u2010to\u2010body weight ratios makes it difficult to accurately estimate the biomass of harvested sharks based on their traded fins and weakens CITES enforcement. This study determines species\u2010specific fin\u2010to\u2010body weight ratios for shark species caught by the artisanal fishery in the southern Gulf of Mexico. Wet fin weights of primary fins from 479 individuals, belonging to 19 species and six families, indicated that\n                    <jats:italic>Carcharhinus leucas<\/jats:italic>\n                    (43.6%),\n                    <jats:italic>C.\u2009plumbeus<\/jats:italic>\n                    (18.8%),\n                    <jats:italic>C.\u2009obscurus<\/jats:italic>\n                    (15.0%) and\n                    <jats:italic>Sphyrna lewini<\/jats:italic>\n                    (6.6%) were the most significant large\u2010bodied species involved in the international shark fin trade from the southern Gulf of Mexico. The species\u2010specific mean wet fin weight to total body weight ratios ranged from 1.22% to 3.44%, while wet fin weight to trunk weight ratios varied between 1.40% and 5.73%. Furthermore, the dry fin weight\u2010to\u2010trunk weight ratios oscillated from 0.52% to 1.71%, and the dry fin weight\u2010to\u2010trunk weight ratios ranged from 0.58% to 2.86%. The mean dry\u2010to\u2010wet fin conversion factor was estimated at 42.9%.\n                    <jats:italic>Alopias superciliosus<\/jats:italic>\n                    ,\n                    <jats:italic>C.\u2009altimus<\/jats:italic>\n                    ,\n                    <jats:italic>C.\u2009leucas<\/jats:italic>\n                    ,\n                    <jats:italic>C.\u2009obscurus<\/jats:italic>\n                    ,\n                    <jats:italic>C.\u2009plumbeus<\/jats:italic>\n                    and\n                    <jats:italic>Isurus paucus<\/jats:italic>\n                    exhibited the highest fin\u2010to\u2010body weight ratios.
