摘要

It is well-established that aquatic organisms are constantly being invaded, which threatens biodiversity. Even so, knowledge about the role of parasites in such invasion events remains insufficient and often overlooked in most ecological studies. We conducted a systematic review to gain a deeper understanding of the mechanisms that sustain these invasions by tracing the origins of the pathogens, identifying the factors that facilitate their invasions, determining the hosts and parasite groups most frequently impacted, and identifying which regions harbor the most invasion reports. To this end, a literature search was carried out using the PRISMA Protocol and network analyses to detect patterns of parasite-host interactions. In total, 870 invasion records were compiled for 262 fish species and 186 parasite species, with 305 spillback or dilution effects and 565 spillover records. Invasion events were primarily associated with fish farming, and Asia is the largest disperser of invasive parasite species, probably due to the extensive and global production of fish from this continent. The interaction networks, despite visually nested, exhibited low nestedness and high modularity, which may be related to parasite specificity, the likelihood of parasites and hosts encounters, and the presence of unique interactions registered in this review. This study reinforces the importance of monitoring fish farms to prevent escapes and the co-introduction of parasites and hosts, which can contribute to the biotic homogenization of both the ichthyofauna and the parasite fauna.
