Because of problems with insecticide resistance, alternative malaria control methods were necessary. These methods include the use of biological control agents, such as larvivorous fish. This study aimed to study the larval eating capacity of three indigenous larvivorous fishes in malaria control in laboratory conditions in Dogbo district in south-western Republic of Benin, West Africa. Larvae of Anopheles gambiae sensu lato mosquitoes were collected from breeding sites using the dipping method in July 2020 during the rainy season in Dogbo district. Alive Hemichromis fasciatus, Clarias gariepinus and Oreochromis niloticus fishes were bought immediately once catched by fishers of Ganvié location in So-Ava district and carried by car from Ganvié location to the Laboratory. Laboratory evaluation for larvivorous efficacy was conducted. The results obtained in the current study showed that the larval eating capacity of Hemichromis fasciatus fish when this fish was fed was the highest among those of the three tested indigenous larvivorous fishes in the laboratory conditions. Similar results were obtained when theses different fishes were unfed. In a context of environmental crisis and global changes, environmentally friendly methods should be encouraged. The use of indigenous larvivorous fishes as predators to control malaria mosquitoes is obviously insufficient in the current study.
