Paretroplus menarambo is an endemic Malagasy cichlid presumed extinct in 2004, was rediscovered in 2008 within lake Tseny ( 641 hectares). This lake is situated at Tsaratanana municipality in the Port-Bergé district, SOFIA Region. The species is classified as Critically Endangered on the IUCN Red list, indicating an extremely high risk of extinction. Adult individuals exhibit prominent reddish-browns margins on their fins. Their ecological niches are characterized by dense macrophyte cover areas ( Nymphaea sp; and Phragmites) as well as submerged root systems and decaying woody debris. Damba faces significant threats from local consummation, invasive species, unregulated fishing practices and habitat destruction. Ecological monitoring conducted from 2017 to 2021 has provided critical insights into species’ distribution. Data confirms that the population is now concentrated within a highly restricted refuge in the western part of the lake. Continuation of such monitoring is essential to capture long-term trends, validate adaptive management strategies, and guide community-led conservation initiatives. This project aims to build local capacity through the training of community lake patrollers and technicians in standardized monitoring methods and integrating scientific data with community decision-making, ensuring a sustainable path toward the recovery of Damba and the overall improvement of Lake Tseny’s ecological integrity.
