Molecular identification of sharks and rays species from Aceh waters, Indonesia

Depik Jurnal, 2023
Shark is a cartilaginous fish that is widely hunted because it has high economic value. The waters of Aceh are directly adjacent to the Indian Ocean and the Malacca Strait making it a preferred habitat for pelagic fish, especially sharks.

Residency and spatial use by reef sharks of an isolated seamount and its implications for conservation. [PDF]

PLoS ONE, 2012
Although marine protected areas (MPAs) are a common conservation strategy, these areas are often designed with little prior knowledge of the spatial behaviour of the species they are designed to protect.

Vulnerability of tropical fish communities across depth in the central Indian Ocean. [PDF]

Conserv Biol
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

Comparative Space Use of Sympatric Sharks at a Remote Island in the South Pacific Ocean. [PDF]

Ecol Evol
The space use of 34 dusky (Carcharhinus obscurus), 32 Galapagos (C. galapagensis), 47 tiger (Galeocerdo cuvier), and 20 sandbar (C. plumbeus) sharks was monitored with acoustic telemetry between 2021 and 2024 in coastal waters around Norfolk Island, Australia, a remote small island in the southwestern Pacific Ocean.

Quantifying shark distribution patterns and species-habitat associations: implications of marine park zoning. [PDF]

PLoS ONE, 2014
Quantifying shark distribution patterns and species-specific habitat associations in response to geographic and environmental drivers is critical to assessing risk of exposure to fishing, habitat degradation, and the effects of climate change.

Evaluation of Shifts in the Potential Future Distributions of Carcharhinid Sharks Under Different Climate Change Scenarios

Frontiers in Marine Science, 2022
Climate change is currently considered one of the main phenomena affecting marine species through expansion or contraction of their distribution. Being ectothermic organisms, sharks of the family Carcharhinidae could be highly susceptible to the effects ...

Long-term changes in species composition and relative abundances of sharks at a provisioning site. [PDF]

PLoS ONE, 2014
Diving with sharks, often in combination with food baiting/provisioning, has become an important product of today's recreational dive industry. Whereas the effects baiting/provisioning has on the behaviour and abundance of individual shark species are ...

Low diversity and abundance of predatory fishes in a peripheral coral reef ecosystem. [PDF]

Ecol Evol
Our findings provide insights into the structuring of coral reef fish communities, demonstrating that distinct assemblages can occur within semi‐enclosed seas at smaller spatial scales than previously documented. We also report a low abundance of threatened fish species in an area of rapid, large‐scale coastal development, which identifies an urgent ...

Tubbataha Reefs Natural Park: the first comprehensive elasmobranch assessment reveals global hotspot for reef sharks

Journal of Asia-Pacific Biodiversity, 2019
Elasmobranchs are experiencing population declines worldwide because of anthropogenic stressors. Marine protected areas (MPAs) have been shown to benefit mesopredatory species of shark.

The Overlooked Threat of Global Warming on Elasmobranch Fertility

Fish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.
ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.
