International or regional conventions
Ghana is a member/signatory to the following international and regional Conventions related to cetacean conservation:
- International Whaling Commission (since 2009)
- Convention on Migratory Species (since 1988)
- The Abidjan convention
- Memorandum of Understanding Concerning the Conservation of the Manatee and Small Cetaceans of Western Africa and Macaronesia
There are no known records of Sousa teuszii from Ghana. Limited cetacean surveys and extensive studies on the cetaceans found in fisheries bycatch indicate that the lack of observations is probably a true reflection of the species absence in this country’s waters.
Threats and trends
Given the high levels of cetacean bycatch recorded in Ghana’s fisheries (Debrah et al. 2010), it is possible that Sousa teuszii has been locally extirpated.
