Project Manta Ray aims to investigate impacts of divers on cleaning stations utilised by Manta Rays aswell as on pristine reefs. Diving tourism is a growing industry, and is highly dependent on the healthy condition of its natural resource base.
There is, however, strong concern that intensive use of marine ecosystem for SCUBA diving has resulted in a loss of biodiversity and the non-sustainability of eco-tourism sectors. In Mozambique this concern is real, particularly in the marine mega fauna diving industry, such as with manta rays, which are one of the main marine attractions to southern Mozambique. Project manta ray aims to address shortfalls in the current understanding of the impact that commercial eco-tourism has on the integrity of marine ecosystems.
Zavora Marine Lab will only conduct research with required permit approval from relevant Mozambican authorities.
The project is headed by, Brazilian marine scientist Yara Tibirica at Zavora Marine Lab, Mozambique.
Use of underwater photo-identification, parallel lasers to establish population estimates and composition data on manta rays utilising Zavora Bay.
Collaborative research with the foundation for the Protection of Marine Megafauna (particularly manta rays and whale sharks) using photo-identification techniques to enhance understanding of species distribution, regionally and globally.
Direct estimation of the total abundance of humpback whale population using the Zavora area falls outside the scope of this study. Daily visual estimates of cetacean group sizes (the number of individuals and relative location within the bay) will show patterns in relative abundance throughout the year.
Additionally, the lab has complementary studies on fish and nudibranchs diversity. One of the major interest is the presence/absence description throughout the year of the biggest and rarest ray in the world: the small eyed stingray which has been filmed alive only in Inhambane province. Besides new species of Nudibranchs have been discovered at the Zavora bay.
No Behavioural research projects active at present
No physiological research projects active at present
Using standardised coral reef monitoring protocols (Reef Check Moçambique) which include video transect survey, the project aimes at monitoring the long term impact of diver presence on reef structure and create baseline information to future management
Use of direct observation and standardized techniques to collect divers impacts in the presence and absence of manta rays.
A creative educational project at the local school combining filming, open arena cinema and environmental activities for villagers to encourage the engagement of local community on marine conservation and foster the education of young children in remote areas such as Zavora.
No past research projects.
