“…These results match previous studies, as it is known that A. anatina, U. pictorum, and U. tumidus are hosts for the European bitterling (Balon, 1962;Wiepkema, 1961;Reynolds et al, 1997). Furthermore, it is also known to date that among co-occurring mussel species U. crassus (Tatoj et al, 2017), A. cygnea (Linnaeus, 1758) (Reynolds et al, 1997), Pseudunio auricularius (Spengler, 1793) (Soler et al, 1999), Microcondylaea bonellii (Férussac, 1827) (Sousa et al, 2020), U. mancus Lamarck, 1819, and Potomida litoralis (Cuvier, 1798) are suitable native European hosts for the European bitterling (Prié, 2017).…”

“…The presence of developing bitterling embryos in the gills may also adversely affect host growth (Reichard et al, 2006). Therefore, the European bitterling should be regarded as a mussel parasite (Sousa et al, 2020;Brian et al, 2022). As such, the degree of historical coexistence between bitterling and mussel populations in Europe is crucial to the understanding of their relationship from an evolutionary viewpoint (Van Damme et al, 2007).…”

“…This study reinforces the hypothesis of Soler et al (2019), stating that Rhodeus amarus can utilise all European unionid species within its current range, including rare European species as occasional hosts, including Unio crassus (Tatoj et al, 2017;Lewisch et al, 2023) and Pseudanodonta complanata (Smith et al, 2004; this study). However, despite their capacity for using a wide range of hosts, field and laboratory studies show that European bitterling are choosy about which species of freshwater mussel they use for oviposition (Balon, 1962;Aldridge, 1997;Kondo et al, 1984;Smith et al, 2000;Reichard et al, 2010Reichard et al, , 2015Soler et al, 2019;Sousa et al, 2020). It has been demonstrated that both the number of previously laid eggs and mussel species affect oviposition decisions, although not the number of eggs laid by the female bitterling when oviposition occurs (Smith et al, 2000).…”

This study explores the utilisation of European freshwater mussels as hosts by the European bitterling (Rhodeus amarus) at their current sympatric occurrence range. Our study confirms Pseudanodonta complanata as a suitable, occasional host for bitterling. The spawning relationship of R. amarus with freshwater mussels has physiological costs for the hosts, leading to resource competition and potential negative effects on host fertility. Further research is needed to assess the dynamics of host-parasite interactions, mussel adaptations to prevent parasitism, and the consequences of the bitterling recent and possible future expansion in Europe for mussel populations.

Taxonomic Reassessment of Freshwater Mussels from the Western Balkans Reveals an Overlooked but Critical Refugium and Defines Conservation Priorities

et al. 2022

Freshwater mussels are an endangered group of animals, especially in the water bodies of Central and Western Europe. Conservation priorities were established for many endangered freshwater mussel species in the last decade. Here, we present new data on a cryptic refugium of freshwater mussels in the Western Balkans. Two species, Anodonta exulcerata Porro, 1838 and Unio elongatulus Pfeiffer, 1825, were discovered in Montenegro for the first time. The phylogenetic position and taxonomic status of freshwater mussel species from Montenegro were studied by means of an integrative approach, combining morphological data and COI gene sequences. Unio carneus Küster, 1854 stat. rev. represents a species with a restricted range, which is endemic to the Western Balkans. A viable population of Microcondylaea bonellii (Férussac, 1827) was discovered in the Zeta River. This species was not mentioned in Montenegro since the 1900s. A significant level of genetic diversity was revealed for the studied species. In the Skadar Lake basin, freshwater mussels from diverse ecological groups were discovered. Rheophilic species of freshwater mussels may represent ancient lineages, which need special conservation planning. Conservation priorities should be aimed at the protection of freshwater mussel habitats on the Balkan Peninsula.

“…The high conservation status of the bitterling has sometimes been questioned (Van Damme et al, 2007), even though current population trends within its historical distribution remain unknown (Freyhof & Kottelat, 2008). There are indications that the species is increasing its range in the east and south of Europe, with potentially harmful effects on endangered mussel populations (Kozhara et al 2007;Prié, 2017;Soler, Wantzen & Araujo, 2019;Sousa et al, 2020). As parasitism by bitterling can indeed have some adverse effects on infested mussels (Methling, Douda & Reichard, 2019), its introduction to new areas should be prevented.…”

1. Local extinctions break species interactions and have cascading effects throughout ecosystems; parasites are often severely affected. The European bitterling, Rhodeus amarus, is a cyprinid fish that parasitizes unionid mussels by laying eggs into the mussel gill cavity, where embryos develop and emerge as active juveniles; this relationship is obligatory for the bitterling.2. This article describes a field experiment aimed at averting the secondary extinction of the European bitterling after a complete die-off of a freshwater mussel community, as a result of habitat destruction.3. Approximately 5,000 unionid mussels were reintroduced within the short time frame in which the remnant bitterling population was still present at the site.Mussel survival was high, and bitterling resumed reproduction, with vigorous courtship observed within 24 hours of mussel release. Recruitment was successful, as evidenced by increased occupancy, densities, and relative frequencies in the fish assemblage. The frequency of sub-adults and young-of-the-year changed from 0% before mussel reintroduction to 80% a year later, and 50% 2 years later, when young-of-the-year contributed to about half of the young fish. No bitterling were observed at two control sites where mussels were not reintroduced.4. This study exemplifies how the timely restitution of affiliate species can avert co-extinction. It also shows how the conservation of the bitterling within its historical distribution range can serve mussel conservation, including species that although not legally protected, are important keystone species and ecosystem engineers, shaping the structure and function of a broad range of freshwater habitats.
