Corrigendum: Use of Synthetic Salmon GnRH and Domperidone (Ovaprim®) in Sharks: Preparation for ex situ Conservation

Frontiers in Marine Science, 2021
In the original article, there was an error. We have used the whitetip reef shark (Triaenodon obesus) for this study but wrote the species name incorrectly as the Oceanic whitetip shark (Carcharhinus longimanus).

Abundance, demography and population structure of the grey reef shark (Carcharhinus amblyrhynchos) and the white tip reef shark (Triaenodon obesus) (Fam. Charcharhinidae) [PDF]

, 2006
Reef sharks (fam. Carcharhinidae) are high-order predators, found throughout the Indo- Pacific. I examined the abundance, growth, reproduction and demography of two species of reef carcharhinid; the grey reef shark (Carcharhinus amblyrhynchos) and the whitetip reef shark (Triaenodon obesus), and investigated the genetic stock structure of T.

Defining ecological roles of sharks on coral reefs. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Sharks have often been perceived to play a critical role in the dynamics of coral reef ecosystems globally. Yet, there is relatively little evidence to support this idea across all but a limited set of species and contexts. Research on the roles and importance of reef sharks has been complicated by logistical challenges in collecting data on ...

The Phenomenon of Piebaldism in Sharks: A Review of Global Sightings and Patterns. [PDF]

Ecol Evol
Chromatic disorders like piebaldism—a rare form of leucism causing partial pigment loss—have been documented in 25 wild shark cases across 17 species and 11 families, with varying anatomical distribution. This study compiles published and unpublished records to better understand the taxonomic and geographical spread of piebaldism and its potential ...

Summarising 40 years of gastric lavage studies to evaluate efficiency and survival in sharks and rays. [PDF]

J Fish Biol
Abstract Traditionally, lethal stomach dissection has been used to study the diets of sharks and rays, but conservation and animal welfare concerns necessitate non‐lethal alternatives, such as gastric lavage (stomach or gut flushing). In this study, we summarised gastric lavage studies on elasmobranchs to identify which species/groups it has been ...

Use of Synthetic Salmon GnRH and Domperidone (Ovaprim®) in Sharks: Preparation for ex situ Conservation

Frontiers in Marine Science, 2020
Shark populations are constantly decreasing owing to environmental destruction and overfishing; thus, sharks are now at a risk of extinction, with 27.9% of shark species classified as endangered on the International Union for Conservation of Nature’s Red
