The work described here employs a new combination of methods to identify parasite species and study parasite succession in fry of perch (<jats:italic>Perca fluviatilis<\/jats:italic>) from Lake Constance, Germany. Classical morphological diagnostics are combined with sequence comparisons between parasite life-stages collected from various hosts within the same ecosystem. In perch fry at different stages of development, 13 different parasite species were found. Incomplete morphological identifications of cestodes of the order Proteocephalidea, and trematodes of the family Diplostomatidae were complemented with sequences of mitochondrial DNA (cytochrome oxidase 1) and\/or nuclear (28\u00a0s rDNA) genes. Sequences were compared to published data and used to link the parasites in perch to stages from molluscs, arthropods and more easily identifiable developmental stages from other fishes collected in Lake Constance, which both aided parasite identification and clarified transmission pathways. There were distinct changes in parasite community composition and abundance associated with perch fry age and habitat shifts. Some parasites became more abundant in older fish, whereas the composition of parasite communities was more strongly affected by the ontogenetic shifts from the pelagic to the littoral zone.<\/jats:p>","DOI":"10.1017\/s0031182012001989","type":"journal-article","created":{"date-parts":[[2013,1,2]],"date-time":"2013-01-02T04:52:53Z","timestamp":1357102373000},"page":"509-520","source":"Crossref","is-referenced-by-count":50,"title":["Parasite
