According to the earlier Symposia, the topics addressed at this conference will focus on anything that can improve the knowledge of aquatic oligochaetes in the broadest sense, i.e. including Branchiobdellida, Acanthobdellida, and Hirudinida. Among these, we can cite the following: Applied ecology (assessment, rarity, conservation value): Marine ecology (biology); Ecotoxicology (bioassays, laboratory culture); Biology (population dynamics, reproduction); Morphology (internal and external structures); Taxonomy (phylogeny and systematics); Biogeography (biodiversity and distribution mechanisms); Application in management (sludge ecology); New methods and techniques.

Both oral and poster presentations are welcome.
