In the rice fields can be found several species of snails. One of them is Pila scutata which can be used as a source of protein. There is not much research on the snails, especially in rice fields in Bali. Research was conducted to determine the density, egg number, and nutritional content of the snail in rice fields of the subak Uma Desa, Duda Village, Karangasem Regency, Bali. Snail were collected from three plots of rice fields which already planted with rice plant. At each rice field plots are placed a quadrate made of pipes measuring 1 x 1 m, then the snails with all the sizes contained in the quadrate are taken. Sampling of snail eggs was also carried out in three rice fields where the snail samples were collected, namely by searching the entire area. Measurement of environmental factors were carried out every sampling. The samples of snails and their eggs were brought to the laboratory to be counted, observed for morphology and morphometry and counted the eggs in a eggs group. Furthermore, the snail samples were analyzed for their nutritional content. The results showed that the density of the snails was 4.67 ind/m², frequency of presence was absolute, and distribution pattern was regular. The snails was mostly found in sheltered places. Egg groups are white, found in sheltered areas and above the waterline. The protein content of the snails was 52.57%.
