Elasmobranch microbiomes: emerging patterns and implications for host health and ecology

Animal Microbiome, 2021
Elasmobranchs (sharks, skates and rays) are of broad ecological, economic, and societal value. These globally important fishes are experiencing sharp population declines as a result of human activity in the oceans.

Mitigation of Elasmobranch Bycatch in Trawlers: A Case Study in Indian Fisheries

Frontiers in Marine Science, 2020
Bycatch poses a significant threat to marine megafauna, such as elasmobranchs. India has one of the highest elasmobranch landings globally, through both targeted catch and bycatch.

Development of Sperm Cryopreservation Protocols for Sharks and Rays: New Tools for Elasmobranch Conservation

Frontiers in Marine Science, 2021
Elasmobranchs are one of the most endangered vertebrate groups on the planet, but despite this situation the use of reproductive techniques in elasmobranch conservation strategies has been scarce. Among these techniques, sperm preservation is a potential

Fish and coral communities shape elasmobranch reef use in southern Mozambique [PDF]

Scientific Reports
Few studies have explored whether a reef’s bioecological structure affects the presence of elasmobranchs. To examine if the structure of a reef’s fish and coral community influences the likelihood of observing certain elasmobranch species, we deployed a ...

Elasmobranch bycatch distributions and mortality: Insights from the European tropical tuna purse-seine fishery

Global Ecology and Conservation, 2020
Despite bycatch of elasmobranch (sharks and rays) being a major concern in most fisheries worldwide, there is a lack of knowledge on their spatio-temporal species distribution, biology (life stage and sex-ratios), as well as their at-haulback mortality ...

An integrated multi-source dataset of elasmobranchs in the Red Sea following the Red Sea Decade Expedition [PDF]

Scientific Data
Red Sea elasmobranch populations are facing alarming declines. Effective conservation efforts require management strategies informed by extensive datasets and by developing an understanding of distribution patterns within the basin, which is currently ...

Predictive habitat suitability models to aid conservation of elasmobranch diversity in the central Mediterranean Sea [PDF]

Scientific Reports, 2015
Commercial fisheries have dramatically impacted elasmobranch populations worldwide. With high capture and bycatch rates, the abundance of many species is rapidly declining and around a quarter of the world’s sharks and rays are threatened with extinction.
