    In order to investigate the influence of intraspecifc hybridization on the growth rate of fsh, the aquarium fsh Trichogaster trichopterus (Pallas, 1770), namely the Blue and Gold variations, were chosen as the object of study. The research aimed to elucidate the differences regarding the growth rate between the individuals obtained as a result of intraspecifc hybridization and the non-hybridized parental forms. In the descendants obtained by hybridization, a signifcant variation of the parameters can be seen, compared to the non-hybridized specimens. starting from the very frst days, a signifcant increase in weight is observed in the hybrid fsh. already from the initial stage, the hybrid offspring exceed the length of the non-hybrid offspring by about 40 %. Intraspecifc hybridization can be successfully used as a method to enhance the growth rate of the ornamental fsh Trichogaster trichopterus.

    MONITORIZAREA EPIZOOTICĂ A OBIECTIVELOR ACVATICE PISCICOLE

    The theoretical basis of modern ecological and epizootic monitoring technology in fish farms can be the biotic concept, according to which parasitological and microbiological monitoring data are used for ecological and epizootic assessment of a fishing reservoir, and physical and chemical indicators act as potential causes for deviations from structural and functional norms in hydrobiological communities.

    POSIBILE MODIFICĂRI ALE IHTIOPARAZITOFAUNEI ÎN CONDIŢIILE SCHIMBĂRILOR CLIMATICE

    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.

    PRACTICI INTERNAȚIONALE PRIVIND APLICAREA MĂSURILOR ANTIEPIZOOTICE ÎN PISCILCULTURĂ
    (CEP USM, 2023-02-17) Rusu, Vadim; Ciocârlan, Victor; Dumbrăveanu, Dorin; Croitoru, Ion; Budeanu, Mihail; Pîrţu, Igor
    n international practice, the main disease prevention measures in fish farming are: disease monitoring, territorial zoning according to the identified disease and species susceptible to it, information about the identified disease. The application of these measures is a prerequisite for ensuring the epizootic safety of international trade in aquaculture items. From a legislative point of view, this practice was introduced in the early 90s of the 20th century and has proven to be reliable and effective.
