Abstract

The reproduction study of the snail Archachatina ventricosa took place at the National Center of Floristic (NCF) from January 2017 to December 2018 for two years. All the different plots of the NCF were searched monthly according to a chronogram to look for snails in mating. In addition, dissections were carried out each month on 15 snails to detect ovigerous snails and the average number of eggs per snail. Then histological sections were made on 180 individuals of this same species for the study of gametic maturation. The results of this study made it possible to locate the reproduction period of this snail in a natural environment. This period extends from March to December with high mating frequencies between the months of July and August. a total of five ovigerous snails were harvested with 33 eggs, an average of 6.6 ± 1.52 eggs per snail. Mating is for individuals larger than 6 cm. The study of gametic maturation revealed that gametogenesis begins at 6 cm by spermatogenesis and has five stages of maturation. Sexual maturity is reached from 7 cm in length, which corresponds to 22 months of age.From the results of this study, it can be suggested that the collect of these snails when they measure more than 9 cm.
