eShark Project




eOceans and eShark is a collaborative scientific initiative, headquartered at Dalhousie University, focused on informing ocean conservation efforts with “crowd-sourced” data. Marine citizen scientists, ocean industry professionals and others who actively explore our blue planet make important observations every day. We’re collecting these data and combining it with traditional and expert datasets to build a comprehensive ecological baseline of marine environments all over the world.

What is eShark?

eOceans_GreeneShark now falls under the umbrella project called eOceans. eShark provides a simple way for divers, snorkelers, paddle boarders, beach waters and even fishermen to report the sharks, rays and sawfish they observe for conservation. These observations or lack of observations are used to assess and monitor populations, communities and ecosystems. Most importantly the data is used to assess the need for marine sanctuaries, and monitor marine management initiatives already in place.

eShark and Shark Guardian Partnership

Shark Guardian has been instrumental in the success of eShark in Thailand. Shark Guardian regularly tours Thailand giving science-based talks to various audiences about the value of sharks to their ecosystem and describing their conservation concerns. While delivering these presentations they also encourage divers and fishers to participate and contribute their observations to eShark. Shark Guardian requests (almost) monthly progress reports from eShark which they use to target their efforts, celebrate the successes of the participants, and encourage regular participation to this concentrated count. Thanks to the efforts of Shark Guardian, eShark now has >13,000 records submitted from Thailand – one of the largest concentrated censuses in the eShark database!

eShark was developed from the Global Shark Assessment, which was an ambitious and successful project started by the late Dr. Ransom Myers and colleagues. The Global Shark Assessment was launched in October of 2003 to assess how global shark populations have changed since the beginning of industrial scale fishing, and to make predictions about how these populations will respond to global climate change and to different methods of fishing.

Previous eShark survey results have been used for several publications to assist with shark conservation. Results if eShark has been used to assist the IUCN data of sharks for the Convention of International Trade of Endangered Species (CITES). list of articles and publications by Christine Ward-Paige
