Insights into the Ecology and Movements of the Blacktip Reef Shark (Carcharhinus melanopterus)

open access: yes
A challenge in studying the natural behaviour of wild animals is the need for detailed observations spanning extended periods of time, which are particularly difficult to obtain in the case of sharks. As a result, tagging and remote sensing technologies are usually employed.

First photographic inland record of blacktip reef sharks Carcharhinus melanopterus (Carcharhiniformes: Carcharhinidae) in Indonesian waters

open access: yesEcologica Montenegrina, 2019
Blacktip reef sharks Carcharhinus melanopterus were caught and photographed by local people on 6 March 2019 during a flash flood in Sentani, Jayapura district, Papua province, Indonesia. The presence of C. melanopterus in Sentani represents the first inland record (c. 20 km) for this species in Indonesia.

Steroid hormones as a non-lethal assessment of the reproductive biology in male and female blacktip reef sharks

open access: yesFrontiers in Fish Science
IntroductionOverexploitation of sharks and the destruction of their habitat has led to severe population declines and the need for conservation and management actions. Effective conservation management requires knowledge of the size at which a shark matures and an understanding of their breeding season, fundamental information to maintain appropriate ...

Ethological Insights into the Ecology and Movements of the Blacktip Reef Shark (Carcharhinus melanopterus) in an Undisturbed Reef Community

open access: yes
A challenge in the ethological study of wild animals is the need for detailed, long-term observations, which work is particularly difficult in the case of sharks. Consequently, most research relies on tagging and remote sensing technologies to provide presence-absence data in which the behavioural and social context is lacking.

Quantifying changes in umbilicus size to estimate the relative age of neonatal blacktip reef sharks (Carcharhinus melanopterus)

open access: yes, 2022
This dataset contains one file with the umbilicus sizes (area and perimeter) of the individuals used in the construction of the temporal regression relationships and one file containing the precaudal length (PCL, in cm), mass (in kg), and body condition (Fulton's K) to assess transitions in morphometrics with age.

The biology and ecology of the blacktip reef shark Carcharhinus melanopterus (Quoy & Gaimard, 1824) and implications for management

open access: yes, 2013
[Extract] This project aimed to provide new information on the biology and ecology of the blacktip reef shark to address key knowledge gaps and provide information that informs the conservation and management of the blacktip reef shark. This thesis uses a vulnerability assessment approach that has been applied in a variety of fisheries and natural ...
