| dc.description | 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 finished product according to the initial density determined in the fattening stage; additionally, difficulty in maintaining an adequate forage supply has limited snail production. In this study, the influence of snail density using balanced food supply on the final production was studied in an open sky system. Density had no significant effect on the mean final 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 (low density); however, the difference between the moderate snail density (100 snail·m-2) and the low density was not significant. The highest productivity per unit of surface was about 510 g·m2 (n = 200), which is similar to the amount that heliciculture producers want to achieve and slightly lower than what has been reported previously. La helicicultura es una actividad practicada en diversas regiones del mundo que ha sido promocionada en Argentina en los últimos años. Sin embargo, su expansión se ha limitado por diversos factores que han impedido lograr una producción adecuada a escala comercial. Entre estos factores se destacan la imposibilidad de obtener una cantidad adecuada de producto terminado y la dificultad de mantener una oferta forrajera acorde con las necesidades. En el presente trabajo se estudió la infl uencia de la densidad de cría (50, 100 y 200 caracoles·m-2) y la suplementación con alimento balanceado en la producción fi nal de caracoles (Helix aspersa), para un sistema abierto y por unidad de superfi cie productiva. El peso vivo promedio fi nal no mostró diferencias significativas para distintas densidades de cría. En la densidad mayor, 200 caracoles·m-1, el diámetro individual fue significativamente menor respecto a 50 caracoles·m-2 (densidad menor). No se encontraron diferencias significativas entre la densidad media (100 caracoles·m-2) y la menor. La máxima productividad por unidad de superfi cie fue de 510 g·m-2 (un grupo original de n = 200), cantidad similar a la que pretenden lograr algunos productores helicícolas argentinos y sensiblemente inferior a la extensamente publicitada (1000 g·m-2). | en-US |
