    REVIEW OF THE RECENT FINDINGS ON THE ICHTHYOFAUNA OF THE PRUT RIVER, REPUBLIC OF MOLDOVA
    (CEP USM, 2024) Bulat, Dumitru; Bulat, Denis; Zubcov, Elena; Bileţchi, Lucia; Şaptefraţi, Nicolae; Ene, Antoaneta; Patriche, Neculai
    The investigations carried out in 2010-2022 in the Prut River basin within territorial limits of the Republic of Moldova revealed an ichthyofaunistic diversity consisting of 62 species from 13 orders and 22 families, of which 14 species are considered endemic to the Danube basin. A new species was identified in the Prut River in 2010 – Gymnocephalus baloni (Holcík & Hensel, 1974). Later, in 2015, the species Benthophilus nudus (Berg, 1898) was recorded for the first time in the Prut River, and in 2022 – Rutilus virgo (Heckel, 1852). The obvious biological progression of Gobiidae species in last decades is an alarming sign related to the stability of native ichthyocenoses. The analysis of the flow, spatial, trophic and reproductive preferences of fish denoted that most of species are eurytopic, benthic, omnivorous, lithophilous or phytophilous.

    POSIBILE MODIFICĂRI ALE IHTIOPARAZITOFAUNEI ÎN CONDIŢIILE SCHIMBĂRILOR CLIMATICE
    (CEP USM, 2023-02-13) Rusu, Vadim; Ciocârlan, Victor; Dumbrăveanu, Dorin; Croitoru, Ion; Budeanu, Mihail; Pîrţu, Igor
    Under conditions of increased water temperature caused by global warming, the physiology of fish will change, there will be changes in parasite-host relationships, where some fish with a wide ecological valence may experience the negative impact of parasites due to their large numbers, as well as with the emergence to new species, such as Neoichthyophthirius schlotfeldti, with which there is still no equilibrium in the parasite-host system.
