text: In experiments which compared the amount of live seagrass, epiphytes and macroalgae in cages with or without conch at natural densities (1.2 animals per square meter), researchers found that none of these were significantly affected by the presence of the conch (the relative amount of each within the cages remained unchanged from that outside where the conch had free access), but the amount of detritus in cages without conch was as much as 97 times higher than the amount of detritus in cages with conch.
