Hi!

Expose the snails (in a water container) to artificial photostimulation

for two hours and after examine them under a stereomicroscope for the

presence of larval trematodes.

You can choose between two alternative methods:

1. Put the snail on water with light

2. Make a dissection of the snail and look for cercaria

Photostimulacion is the best way to get cercaria

Photostimulation

the snails were examined individually and repeatedly for cercarial shedding in multi dishes under artificial light for two hours (stimulant period) and 2 ml dechlorinated tape water / snail.
