Achatina fulica snails from two environments (natural and breeding) were subjected to two diets, one based on green fodder and the other in the form of flour concentrate, respectively, in order to assess their impacts on the development of gametes. 50 snails were dissected, with 25 from the natural environment and 25 from the breeding environment. Subsequently, the extraction of gonad (ovotestis) was performed on each of the selected animals. After inclusion, histological sections were made to assess the degree of evolution of gonad according to development scales. This allowed us to identify the different stages of sexual development, sexual maturation per size class according to diets.
