Melita Samoilys participated in a three-day workshop in Grahamstown, South Africa, led by the global IUCN Shark Species Specialist Group (SSSG), to start the process of re-assessing the status of shark and ray populations in the western Indian Ocean. This particular workshop focussed on the endemic and near-endemic species of Sub-Equatorial Africa (Angola-Namibia border around South Africa and north to the Kenya-Somalia border; including Madagascar and SW Indian Ocean islands). The SE coast of South Africa represents one of seven global hotspots for sharks and rays
The SSSG is implementing the Sub-Equatorial Africa Red List Project as part of the Global Shark Trends Project (2018 to 2020). The SSSG has a global remit to re-assess all 1,250 sharks and rays, after the last assessment ~ 17 years ago. The SSSG Project team comprises Nick Dulvy (Global SSSG chair, Simon Fraser University) Pete Kyne (Red List Authority Coordinator, Charles Darwin University), Rima Jabado (Regional Co-Chair, Indian Ocean SSSG, UAE), Dave Ebert (Pacific Shark Research Center, CA, USA) and Riley Pollom (SFU). This first workshop follows the Arabian Seas workshop last year.Read more
Necessarily, since the majority of endemic species occur in South African waters,workshop participants were primarily South Africans
who provided impressive amount of data and biological and taxonomic knowledge, from Stellenbosch University, the South African Department of Agriculture, Forestry and Fisheries, and the South African Shark Conservancy. The broader WIO was represented by Baraka Kuguru from TAFIRI, Tanzania, Stela Fernando from IIP, Mozambique, and Melita Samoilys from Kenya, also as Vice-Chair of the sub-Saharan SSSG. The combination of energy, enthusiasm and love of sharks and rays was palpable and an impressive 102 assessments were completed in the 3 days. Two newsworthy species from our region deserve a mention – Baraka’s whipray – Dr. Kuguru was involved in the description of Maculabata ambigua with Dr. Last from Tasmania; and a range extension for the Halavi guitarfish, 𝘎𝘭𝘢𝘶𝘤𝘰𝘴𝘵𝘦𝘨𝘶𝘴 𝘩𝘢𝘭𝘢𝘷𝘪, into Kenyan waters was confirmed by Rima Jabado, based on photos kindly provided by Dawn Goebbels from Watamu lagoon. This species was assessed as Vulnerable in the recent Persian Gulf workshop and previously was only known from the Red Sea, Persian Gulf and India.
This workshop is the first in the WIO, and will be followed by 1-2 workshops further north later in 2018 to assess the wide-ranging species. The global SSSG intends to develop indices for sharks and rays to meet the 2020 targets set by the Convention on Biological Diversity, which is required to deliver the Strategic Plan for Biodiversity and achieve targets that will ensure sustainable fisheries (Target 6), and that extinctions are avoided (Target 12), of the Sustainable Development Targets, as well as more broadly, SDG 14.
