| Understanding distribution ranges and the daily movement patterns of pelagic fishes are key aspects for the establishment and planning of protected areas for their conservation. In this study the vertical and horizontal movements of scalloped hammerhead sharks, Sphyrna lewini, were recorded in Malpelo and Cocos Island using satellite telemetry. Nine sharks were tagged with satellite transmitters during March 2006, 2007 and 2008 at Malpelo Island, and three hammerhead sharks were tagged at Cocos Island in June 2008. The sharks moved between islands in the Tropical Eastern Pacific and made regional movements from Malpelo to the south of Cocos and around the Malpelo ridge. When away from the island, sharks made infrequent nocturnal short dives down to 1000 m... |

| ABSTRACT The species and sizes of sea turtles present in the Bahía Málaga Conservation Mosaic, Valle del Cauca, were characterized between 2016-2020 through aquatic monitoring and voluntary delivery by native fishermen. The registry of individuals was determined by aquatic monitoring, which was divided into three phases: exploratory sampling, continuous sampling, standardized sampling, plus voluntary deliveries by fishermen in their fishing tasks. A total of 107 hours of effort were used to detect 51 individuals of hawksbill (Eretmochelys imbricata) and black (Chelonia mydas) turtles. These results contribute as a baseline for the knowledge of sea turtles as an effective strategy for research and conservation in Bahía Málaga. |
