Females are depicted in black, males in grey. Directed elasmobranch fishing activities were extensive, but artisanal fisheries were diverse and highly opportunistic. Therefore, sites in eastern Baja California Sur that exclusively targeted elasmobranchs were scarce. In addition, survey efforts were insufficient to adequately document the activities of many artisanal fishing sites. Sharks numerically dominated sampled landings during all seasons, and were primarily represented by similar proportions of large (, P. glauca; I. oxyrinchus) and small {R. longurio, S. californica) species. Mobiila mimkiana was the most abundant ray in overall Baja California Sur landings. Large sharks were fished using drift gillnets and assorted longline gear, whereas small demersal sharks and rays were typically fished with bottom set gillnets and longlines. Teleosts (, Lutjanidae, Serranidae) were the primary targets at most camps, with invertebrates (, squids, Teuthoidea) also commonly targeted. Both teleosts and squids were typically fished with handlines. In addition, many fishermen switched from artisanal fishing to sportfishing periodically, especially in tourist areas. Elasmobranch fishing efforts were greatest for large sharks during summer and autumn among surveyed camps. Rays and small sharks (especially S. californica) were fished throughout the year in a relative
