Technical Sheet of the Breeding Substrate Amendment in Oysters Shells Flour and Meat Yield of the Snails (Archachatina marginata) Produced

This study aims to describe the protocol for making a substrate suitable for the production of snails in a short time with a large amount of consumable flesh. So, snails were raised from the spat stage on different substrates made by soil amendment at different rates (0 %, 5 %, 10 %, 20 %, 30 % et 40 %) out of powder of oyster shells until the end of their growth cycle. On each type of substrate, snails were collected at the end of their growth cycle and their soft tissues were removed from the shell to assess their meat yield. Substrate amended at a rate of 30 % allowed the production of snails with the highest amounts of meat (84.13 31.65g).
