Opis:The objective of this study was to characterize the 2024 lionfish tournament using the freediving and diving techniques as an alternative to mitigate its invasion and fillet yield to promote its consumption in the southern Caribbean, Costa Rica. For this purpose, 116 lionfish (Pterois volitans/miles) were harvested using the Hawaiian hand harpoon fishing method in 4 sites. Total length (LT) ranged from 4.7 to 39.5 cm (24.1 ± 7.6 cm), and body mass (MC) ranged from 1.0 to 669.0 g (232.8 ± 158.8 g), with no significant differences (P > 0.05) found per fishing technique. The distribution of relative frequencies of LT and MC evidenced the presence of three size groups comprised of small, medium, and large fish that could be differentiated with the naked eye. Punta Manzanillo presented the highest catches per unit of effort (CPUE) in number of fish, both with freediving (5.5 fish/h) and diving (7.5 fish/h), and in body mass (1.9 kg/h) with both techniques. The lowest catches with freediving (2.4 fish/h and 0.4 kg/h) and diving (0.2 kg/h) occurred in Punta Mona. Medium fish of 166g gave a better fillet yield (21%) than large fish of 354g (16%) due to the lower proportion of carcasses (72.4% vs. 78.2%, respectively). Low fillet yield and difficulties in catching them have reduced local people’s interest in commercializing them.
