Dr. Gordian R. Mataba is an aquatic scientist and lecturer at the Nelson Mandela African Institution of Science and Technology (NM-AIST) in Tanzania. His expertise lies in aquatic ecology and ecotoxicology, focusing on the study and conservation of freshwater and marine ecosystems. Dr. Mataba’s research includes limnology, water quality assessment, fisheries management, and controlling waterborne disease vectors like mosquito larvae. He is also actively involved in conservation projects, including efforts to protect the endangered Manyara Tilapia in Lake Manyara. Currently, he is pursuing a Ph.D. focusing on ecological and ecotoxicological approaches to mosquito larvae control.

• He is involved in the O.R. Tambo Africa Research Chair Initiative, which focuses on nanoscience and nanotechnology to address development challenges in health, agriculture, and food security. Dr. Mataba has participated in conservation efforts, such as the project aimed at protecting the endangered Manyara Tilapia in Lake Manyara, Tanzania. This initiative reflects his commitment to environmental conservation and sustainable resource management.

Rufford Small Grant (Number 34455-1) for his project titled "Upscaling Conservation Awareness and Compliance Campaign for Conservation of the Endangered Manyara Tilapia (Oreochromis amphimelas) in Lake Manyara, Tanzania." This grant supported his efforts to promote conservation awareness and sustainable practices among local communities to protect the endangered species and its habitat.

🐟 1. Conservation Awareness and Compliance Campaigns for the Endangered Manyara Tilapia

This project, supported by the Rufford Small Grant, aims to:

• Assess the current stock size and ecological habitat of the endangered Manyara Tilapia (Oreochromis amphimelas) in Lake Manyara.
• Restore the population and habitat through fisheries management and dissemination of conservation education.
• Train communities on alternative income-generating activities, such as tree nurseries and poultry farming, to reduce overfishing pressures.

The project addresses threats like overfishing, habitat degradation, and lack of conservation awareness among local communities.

🦟 2. PhD Research on Mosquito Larvae Control in the Lake Manyara Basin

Dr. Mataba's PhD research focuses on integrated strategies to control mosquito oviposition and larval development in northern Tanzania. His studies explore the role of aquatic predators and biocides in regulating mosquito populations, aiming to reduce the spread of waterborne diseases.

🌊 3. Impact of Anthropogenic Pollution and Artisanal Fishing on Tilapia Populations

In collaboration with colleagues, Dr. Mataba co-authored a study examining the effects of anthropogenic pollution and artisanal fishing on the populations of Tilapia species, including Oreochromis niloticus and Oreochromis amphimelas, in Lake Manyara. The research highlights the challenges posed by pollution and unsustainable fishing practices on fish stocks and local livelihoods.
