Abstract

Parasites of aquatic organisms are of considerable relevance, especially because of their impact on aquaculture and fisheries systems around the world. In Brazil, aquaculture is important due to the large production of fish for feeding and production of ornamental fish. Some of the agents responsible for fish diseases are myxozoans, which can cause significant economic losses with high mortality rates. Myxozoans are a group of parasitic cnidarians that have a complex life cycle, including a vertebrate host, mainly fish, and an invertebrate host, usually annelids. Many myxozoans are still unknown by the scientific community, and their potential to cause diseases in economically important fish is undetermined. The Tietê river (São Paulo, Brazil) is anthropogenic, has a high diversity of fish species, and there is no other study being done in this river on the diversity of myxozoans. This river offers fish in abundance for human consumption and so it is important to study the diversity of parasites of these fish. The objective of this study is to identify morphologically and molecularly the myxozoans parasites found parasitizing fish from the Tietê River, Brazil, through the partial sequencing of the SSU rDNA gene.
