Abstract

Millions of people suffer from infections transmitted by arthropod vectors. Among them, culicidae are undoubtedly those of greatest hygienic-sanitary importance, especially in tropical and subtropical regions, so biological control, as an alternative to confront vector organisms, is becoming increasingly necessary due to the development of resistance to insecticides. With the objective of knowing the fish species that inhabit the fluvial ecosystems of Varadero, Matanzas province, Cuba, the following research was carried out, which covered the health areas of Santa Marta and Varadero, for which eight fluvial ecosystems were sampled, during January 24 and 25, 2020. The sampling unit used was the jamb, with the following dimensions (70x50x50 cm), with 150 cm of handle. Six fish species grouped into six genera and three families were identified. Gambusia puncticulata and Limia vittata turned out to be the best represented and distributed species; in the case of the first species, it was present in all the sampled reservoirs and even in brackish water reservoirs. The best represented family in the study was the Poeciliidae, present in 100% of the river ecosystems sampled, while, of all the fish species identified, those with the best bioregulatory potential on mosquito larvae were G. puncticulata and L. vittata.
