In each system is good if there are enough species with diferentes trophic categories, in your case, gastropods may indicate any change in the environment, i can recommend some diversity indices such as Pielou's evenness index, simpson index, shannon-wiener index, numbers Hill. A comparison of one or all of these measures of biodiversity can illustrate changes in water quality conditions within a local community. Water quality parameters like light penetration, dissolved oxygen and salinity can have dramatic impacts on levels of biodiversity. Association routines you can use as BIOENV or BIOSTEP to link all components (biotic and abiotic).
