This contribution presents the first record of ornamental shrimp epibiont, Scutariella japonica (Platyhelminthes: Temnocephalida) in European waters. The species lives on freshwater Atyidae shrimp from temperate, subtropical and tropical zones of South-East Asia. In total, 120 individuals of Neocaridina davidi shrimp were caught in thermally polluted canal of Oder river, near the city of Gryfino, in the northwest part of Poland. In that group, 5.83% were infected with scutariellids. Among shrimp, females were mostly infected (85.71%). Since ornamental shrimp released into thermally polluted water bodies have been also noticed in surrounding waters of natural temperature regime in Europe, S. japonica may spread further following potential expansion of the Neocaridina shrimp in Oder river. It is possible that other crustaceans, both native and alien which are present at this location, may also become vectors of this epibiont.
Résumé
Cette contribution présente le premier signalement de l'épibionte des crevettes d'ornement, Scutariella japonica (Platyhelminthes: Temnocephalida) dans les eaux européennes. L'espèce vit sur des crevettes Atyidae d'eau douce provenant des zones tempérées, subtropicales et tropicales de l'Asie du Sud-Est. Au total, 120 individus de crevettes Neocaridina davidi ont été capturés dans un canal thermiquement pollué de la rivière Oder, près de la ville de Gryfino, dans le nord-ouest de la Pologne. Dans ce groupe, 5,83% étaient infectés par des scutariellidés. Parmi les crevettes, les femelles étaient principalement infectées (85,71%). Comme les crevettes d'ornement relâchées dans des plans d'eau thermiquement pollués ont également été remarquées dans les eaux environnantes au régime de température naturel en Europe, S. japonica pourrait se propager davantage suite à l'expansion potentielle des crevettes Neocaridina dans le fleuve Oder. Il est possible que d'autres crustacés, à la fois indigènes et exotiques, présents à cet endroit, deviennent également des vecteurs de cet épibionte.
