Abstract: In 1991, substantial mortality was observed among sterlet fry cultured in the hatchery of TEHAG. The mortality was caused by the oligochaete Chaetogaster limnaei known as a commensalist of snails. Physa acuta, a snail infected by this worm was found in a great number in water-conduits. The commensalist sparely-bristled worms actively moving in the gill and oral cavities and on the body surface prevented the first breath-taking and food intake of immature larvae. As a result, occasionally the entire culture died out. Medication attempts with different doses of formaldehyde, trichlorphon and mebendazole were also made to control the problem.
