“…In TW, fish inhabit different biotopes with features of marine, freshwater and brackish waters, therefore composing a variety of amphihaline, euryhaline and true estuarine fish assemblages (Ray, 2005; Lowe et al ., 2015). Such high variability is mostly determined by the recruitment of species from the sea and/or from rivers, given the relatively small number of truly estuarine fish species (Snigirov et al ., 2019). This set of assemblages with differential halotolerance capabilities (Schultz and McCormick, 2012) and modes of response to natural and anthropogenic factors are expected to harbour an equivalent variety of parasite assemblages with marine, estuarine and freshwater lineages.…”

“…Interesting examples about the effects of environmental features on the composition of parasite assemblages in TW have focused on the influence of hydrological characteristics (Kesting et al ., 1996; Landsberg et al ., 1998; Snigirov et al ., 2019), mainly of salinity profiles (Zander et al ., 1984; Zander, 1998; Blanar et al ., 2011; Rashnavadi et al ., 2014), whose gradients determine concomitant variations in parasite burdens depending on the parasite guilds. Indeed, ectoparasites, which are generally monoxenous and live in direct contact with the surrounding water, are more sensitive not only to changes in salinity, but also to other factors, such as temperature and dissolved oxygen, e.g.…”

Given the abundance, heterogeneity and ubiquity of parasitic organisms, understanding how they influence biodiversity, evolution, health and ecosystem functionality is crucial, especially currently when anthropogenic pressures are altering host–parasite balances. This review describes the features, roles and impacts of metazoan parasites of fish occurring in transitional waters (TW). These aquatic ecosystems are highly productive and widespread around the globe and represent most favourable theatres for parasitism given the availability of hosts (invertebrates, fishes and birds) and an increased probability of parasite transmission, especially of those having complex life cycles. Fascinating examples of how parasitism can influence different hierarchical levels of biological systems, from host individuals and populations to entire aquatic communities, through effects on food webs come from this kind of ecosystem. Edible fish of commercial value found in TW can harbour some parasite species, significantly reducing host health, marketability and food safety, with possible economic and public health consequences. Many TW are historically exploited by humans as sources of relevant ecosystem services, including fisheries and aquaculture, and they are highly vulnerable ecosystems. Alteration of TW can be revealed through the study of parasite communities, contributing, as bioindicators, for assessing environmental changes, health and restoration. Fish parasites can provide much information about TW, but this potential appears to be not fully exploited. More studies are necessary to quantify the ecological, economic and medical impacts fish parasites can have on these important ecosystems.

“…Changes in abundance or community structure of parasitic organisms can be used as indicators of changes in environmental chemistry [37,38]. The use of Acanthocephalus lucii and cestoda Proteocephalus percae in the host intestine as indicators of heavy metal bioaccumulation has been carried out by Sures and Siddall [39,40].…”

Parasitic infections are often not the direct cause of death of fish but the presence of wounds in the fish's body due to parasitic attacks is a trigger factor for secondary infection. Secondary infections can be caused by fungi, bacteria or viruses, which ultimately cause the death of fish. This study aimed to determine the characteristics of parasites and fungi that infected eel (Anguilla sp.) in the waters of Poso, Buol, Toli-toli and Donggala, Central Sulawesi as an important part of the diagnosis of fish disease in the framework of teraupetic strategies. Eel were taken as many as 30 individuals / location for observation of parasites and fungi. Parasitological examination was carried out for external and internal parasites on the mucous layer of the body, gills, intestines and stomach, while fungal isolations were carried out on muscles, skin and tissues that have abnormalities. After identification, the prevalence and intensity were carried out. The results showed that the highest prevalence of parasites were Camallanus sp (70%), Proteacephalus sp (50%) and Gyrodactylus sp (40%), and the nematode Camallanus sp the tapeworm Proteocephalus sp had the highest intensity of 57.5 and 30.8 respectively. Fungal prevalence were found highest in Saprolegnia sp (36%), and Fusarium sp (32%).

Purpose The aim of this study was the comparative analysis of the parasite communities of new populations of invasive pumpkinseed (Lepomis gibbosus) in western Ukraine with pumpkinseed from Czechia, where populations have rapidly expanded over the last two decades. Methods Sampling took place at three localities in the western part of Ukraine (i.e. Dobrotvir Reservoir (Vistula basin), Burshtyn Reservoir (Dniester basin), Mynai Pond (Danube basin)) and four in Czechia (i.e. Oxbow D2, Heršpický Pond (Danube basin), and Kolín oxbow and Římov Reservoir (Elbe basin). Results In total, 11 parasite taxa were recorded in Ukraine and 17 in Czechia. Four species were co-introduced from North America with their host, i.e. the myxosporean Myxobolus dechtiari, the monogeneans Onchocleidus dispar and Onchocleidus similis, and metacercariae of a trematode Posthodiplostomum centrarchi. High dominance indices were related to a high abundance of co-introduced parasites, i.e. O. similis in Mynai pond and P. centrarchi in Dobrotvir Reservoir. Overall abundance of acquired parasites was generally low. Conclusion This study shows that parasite communities in recently established pumpkinseed populations in the western part of Ukraine and Czechia are less diverse than those established in Europe for decades. The generally low parasite load in these new populations may play an important role in their ability to successfully establish and create strong populations by providing a competitive advantage over local species.
