A. aquaticus were introduced into experimental setups of dead eggs, viable eggs and hatched larvae of zebrafish ( Danio rerio ), a commonly used model organism. The amount of A. aquaticus and the duration of their exposure to the eggs significantly affected the proportion of consumed dead eggs in each experimental cycle. A. aquaticus belongs to the group of aquatic detritivores, and no predatory behavior was observed during the experiments. These crustaceans could distinguish between the dead eggs and those containing living embryos. Furthermore, zebrafish larvae remained unharmed by A. aquaticus , even in the absence of alternative food source. These findings underscore the potential sanitary role of these crustaceans in natural waters and offer new perspectives on their possible use as biological control organisms in aquaculture hatcheries. Additionally, our results suggest a potential application of A. aquaticus in combating pathogens by reducing the growth substrates for bacteria and fungi.}, year = {2024}, eissn = {2045-2322}, orcid-numbers = {Quyen, Nguyen Ngoc/0000-0001-5741-590X; Griffitts, Jeffrey/0000-0002-1518-0054} } @article{MTMT:34762462, title = {Cryopreservation of European flat oyster (Ostrea edulis) larvae using a controlled-rate freezer}, url = {https://m2.mtmt.hu/api/publication/34762462}, author = {Horváth, Ákos and Jug-Dujaković, Jurica and Radočaj, Tena and Barić, Oliver and Špelić, Ivan and Balogh, Réka Enikő and Lefler, Kinga Katalin and Kitanović, Nevena and Marinović, Zoran and Urbányi, Béla and Gavrilović, Ana}, doi = {10.1016/j.aquaculture.2024.740887}, journal-iso = {AQUACULTURE}, journal = {AQUACULTURE}, volume = {587}, unique-id = {34762462}, issn = {0044-8486}, year = {2024}, eissn = {1873-5622}, pages = {740887}, orcid-numbers = {Horváth, Ákos/0000-0001-9760-2478; Kitanović, Nevena/0000-0003-4090-1260} } @article{MTMT:34753948, title = {Biological Parameters and Spermatogenesis in Razorfish (Pelecus cultratus) Population Inhabiting the Largest Shallow Lake of Central Europe (Lake Balaton): Studies for In Vitro Conservation Purposes}, url = {https://m2.mtmt.hu/api/publication/34753948}, author = {Bokor, Zoltán and Fodor, Ferenc and Várkonyi, Levente and Nagy, Borbála and Láng, Zete Levente and Ferincz, Árpád and Staszny, Ádám and Molnár, József and Lefler, Kinga Katalin and Csorbai, Balázs and Vancsura, Zoltán and Szári, Zsolt and Urbányi, Béla and Bernáth, Gergely}, doi = {10.1155/2024/6695280}, journal-iso = {AQUAC RES}, journal = {AQUACULTURE RESEARCH}, volume = {2024}, unique-id = {34753948}, issn = {1355-557X}, abstract = {The study aimed to investigate body parameters and the process of spermatogenesis from April to September. In addition, it sought to test the applicability of sperm cryopreservation for conservation purposes in a razorfish (Pelecus cultratus) population of Lake Balaton, the largest shallow lake in Central Europe. During the aforementioned period, measurements were taken for the standard length (SL, cm) and body weight (BW, g), and the sex of specimens was determined. Cells at different stages of spermatogenesis (spermatogonia-SG, spermatocytes-SC, spermatids-ST, and spermatozoa-SZ) were quantified monthly for each male sample. Sperm samples collected at the end of May were cryopreserved using a method designed for common carp. No significant differences were found between males (SL: 25 ± 2 cm and BW: 146 ± 38 g) and females (SL: 26 ± 3 cm and BW: 168 ± 53 g) in terms of measured body parameters. No significant correlations were found between the sex, SL, and BW. High standard deviations were observed for all mean values in all sampling periods, possibly due to the low number of individual samples per month. A significantly higher proportion of SC compared to SZ was found in April. In May, no differences were observed between the four groups. Significantly more SG and SZ than SC and ST were observed in June. In August and September, a slight dominance in the number of SG was recorded, with no differences measured among the cells in different developmental stages. The males studied exhibited a low gonadosomatic index (0.92% ± 0.27%). A significant reduction was recorded in motility (MOT), progressive motility (pMOT), and in most of the kinetic parameters (distance curved line-DCL, curvilinear velocity-VCL, straight line velocity-VSL, and beat cross frequency-BCF). The spermiation of males could have started in May and conceivably lasted until the end of June. It is recommended to increase sperm quality and quantity before cryopreservation.}, year = {2024}, eissn = {1365-2109} } @article{MTMT:34681423, title = {Educational and training innovation opportunities in the aquaculture and fisheries sector of Hungarian secondary agricultural education}, url = {https://m2.mtmt.hu/api/publication/34681423}, author = {Khademi-Vidra, Anikó and Urbányi, Béla and Bakos, Izabella Mária}, doi = {10.1007/s10499-024-01432-4}, journal-iso = {AQUACULT INT}, journal = {AQUACULTURE INTERNATIONAL}, unique-id = {34681423}, issn = {0967-6120}, abstract = {Among the challenges of the aquaculture sector, the present study tries to focus on the necessary modernisation and innovation of the Hungarian sector education by strategically outlining the possibility of a niche secondary-level fisheries PILOT (experimental) training. It is obvious that the “launching” of such a shortage training level is a very complex and long-term task, but in our opinion not unfeasible. To this end, we are considering the development of a multi-stage action plan, the first milestone of which will be a thorough situation survey of the aquaculture education community. The study applies a deductive approach to specific areas of education and training within the general trends in aquaculture, covering the main traces of PILOT training in fisheries as a niche discipline. Our first paper, targeted at educators, focuses on the results of a questionnaire survey of 94 educators. Our main objective was to assess the presence of aquaculture-related knowledge content and associated methodologies in the classroom and the general digital literacy of educators. Our objectives also focus on the general digital readiness of vocational trainers and on the patterns of “professional marketing” opportunities that aquaculture professionals can express.}, year = {2024}, eissn = {1573-143X}, orcid-numbers = {Khademi-Vidra, Anikó/0000-0002-5666-9833; Bakos, Izabella Mária/0000-0001-6626-9481} } @article{MTMT:34535965, title = {Growth of two invasive Cichlids (Perciformes: Cichlidae) in a natural thermal water habitat of temperate Central Europe (Lake Hévíz, Hungary)}, url = {https://m2.mtmt.hu/api/publication/34535965}, author = {Lente, Vera and Staszny, Ádám and Hegedűs, Anna and Bányai, M.
