New location, food composition, and parasitic fauna of the invasive fish Pseudorasbora parva (Temminck & Schlegel, 1846) (Cyprinidae) in Poland

Abstract

The species' rapid dispersal has been facilitated by growing international aquaculture logistics; however, the fish owes it to itself that invading water bodies outside its endemic range may be so successful, as its life history traits allow adaptation and survival in new environments. These mainly include a strong reproductive capability, parental care, and a wide spectrum of tolerated food (Pollux et al., 2006). The dynamic spreading process of the invader has been under scrutiny of a number of authors, including Witkowski (2009), Gozlan et al. Kırankaya (2006). Recently, the knowledge on the species has been enriched with new facts discovered about the behavior, age structure, and growth rates of some novel

Fish Assemblage Shift after Japanese Smelt (Hypomesus nipponensis McAllister, 1963) Invasion in Lake Erhai, a Subtropical Plateau Lake in China

“…Previous studies showed that the accidental introduction of non-native fish produced a sharp, rapid expansion into the ecological niche occupied by native fish, leading to a sharp decline in native fish resources and their eventual extinction [19,20]. Furthermore, the time of Japanese smelt reproduction (January-April) [47] precedes that of the icefish [18] and other species like the sharpbelly [51] and the topmouth gudgeon, an omnivorous fish [52][53][54] that feeds on zooplankton and benthic animals. The result led to food shortages during the early stages of the icefish [55,56], thus causing its decline.…”

“…Our results also showed that the CPUE of topmouth gudgeon decreased significantly after the invasion of Japanese smelt, as well as the changes in CPUE of Japanese smelt and topmouth gudgeon CPUE were significantly negatively correlated. Topmouth gudgeon is an omnivorous fish [52][53][54], which feeds mainly on zooplankton and benthic animals in Lake Erhai [61]. The reproduction of the Japanese smelt population in Lake Erhai occurs mainly from January to April [47], which is earlier than that of the topmouth gudgeon [62].…”

Detection of Ectoparasite Lernaea cyprinacea (Copepoda: Lernaeidae) on some Cypriniformes Fish from the Mediterranean Region of Turkey

“…In the inland waters of Turkey, this order is represented by 278 species according to Çiçek, Sungur, and Fricke (2020). Ecology of parasites of the order Cypriniformes has been the center of an increasing attention for two decades (Dorovskikh & Stepanov, 2009;Soylu, Uzmanoğlu, Çolak, & Soylu, 2017;Gabagambi & Skorping, 2018;Czerniejewski, Rybczyk, Linowska, & Sobecka, 2019).…”
