New insights into the reproductive physiology and culture approaches of Paratilapia sp., a Malagasy cichlid with potential interest for sustainable aquaculture

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.
Abstract One of the primary objectives in freshwater aquaculture is the search for sustainable systems based on agroecological intensification. In this context, the cultivation of local species is decisive, although requiring the identification of new candidates. Malagasy aquaculture is an example of the development of such an approach.
