en un sistema a cielo abierto alimentados con acelga y a suplemento alimentario balanceado

O.M. Gonzalez, G. Perez Camargo, M. Membiela, D. Frezza, N. Bartoloni, and C. Vieites. 2008. Effect of population density on snail productivity (Helix aspersa) in an open sky system fed with Swiss chard and a balanced food supplement. Cien. Inv. Agr. 35(3):251- 257. Heliciculture is performed worldwide and has been promoted in Argentina; however, its development and expansion has been limited by several factors that make it impossible to reach the production volumes necessary for a commercial scale. Among other factors, it has been impossible to obtain a high amount of fi nished product according to the initial density determined in the fattening stage; additionally, diffi culty in maintaining an adequate forage supply has limited snail production. In this study, the infl uence of snail density using balanced food supply on the fi nal production was studied in an open sky system. Density had no signifi cant effect on the mean fi nal live weight. For snails cultured at densities higher than 200 snail·m -2 , the average diameter was lower than for snails cultured at 50 snail·m -2
