Distribution of Blacktip Reef Sharks (Carcharinus melanopterus) Based on Habitat Characteristics by the Baited Remote Underwater Video (BRUV) Method in Morotai Waters of North Maluku

, 2020
Morotai has abundant marine biological resources, sharks being one of them. The blacktip reef shark is one of the dominant types of coral reef sharks in Morotai waters.

Drone-Based High-Resolution Tracking of Aquatic Vertebrates

Drones, 2018
Determining the small-scale movement patterns of marine vertebrates usually requires invasive active acoustic tagging or in-water monitoring, with the inherent behavioural impacts of those techniques.

Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing

Animal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT Assessing genetic structure across ocean basins is essential to understand connectivity and guide conservation in data‐deficient open‐water sharks. In this study, we examined the population genomics of Squalus cf. mitsukurii by analyzing tissue samples collected from two distant regions: California, USA (Pacific Ocean) and Pernambuco, Brazil ...

Compilation of information on the interaction of reef sharks with the reef line fishery in the Great Barrier Reef Marine Park: final report to the Great Barrier Reef Marine Park Authority [PDF]

, 2008
[Extract] Three data sets were examined to define the level of interaction of reef associated sharks with the commercial Coral Reef Fin Fish Fishery (CRFFF) within the Great Barrier Reef. Data were examined from; 1) fishery logbooks from 1989-2006; 2) an

Diversity, Abundance and Distribution of Sharks in a Multispecies Nursery Area in the Eastern Central Atlantic

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 4, April 2026.
ABSTRACT Shark nursery habitats are priority targets for area‐based conservation as they protect key age classes that exhibit restricted area use. However, the lack of detailed, species‐specific biological and ecological data often undermines the efficacy of coastal management strategies. This study employed complementary Baited Remote Underwater Video

Anthropogenic disturbance modifies spatial patterns of reef sharks

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Species‐specific sensitivities mean that non‐extractive human presence can strongly reshape reef predator distributions even where fishing pressure is limited. Integrating tourism intensity and coastal development into marine spatial planning is therefore essential for reef shark conservation, and combining ecological surveys with open‐source social ...

Home range of newborn blacktip reef sharks (Carcharhinus melanopterus), as estimated using mark-recapture and acoustic telemetry

, 2020
Sharks play important functional roles in coral reef ecosystems. Studying reef shark populations' spatial ecology also contributes important data for effective conservation planning.
