Ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI) can provide more information about the internal organs and pathognomic lesions. The authors used diagnostic imaging techniques to evaluate and describe the neoplastic malformation in a 3‐year‐old female rainbow trout ( Oncorhynchus mykiss ). The fish was examined with Siemens Somatom Definition AS + CT scanner and Siemens Biograph mMR scanner. The animal was lethargic and showed anorectic signs and muscular dystrophy. During the post‐mortem investigation, histopathology and immunohistochemistry were also performed allowing us to identify the neoplasms. The results showed a large soft tissue mass in the first mid‐intestine segment, which proved to be an adenocarcinoma. This subsequently led to digestion problems and absorption disorders. Immunohistochemically, neoplastic cells of carcinoma revealed E‐cadherin and pancytokeratin positivity.

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:34760913, title = {Scale morphology is a promising, additional tool for exploring the taxonomy and ecology of freshwater fishes}, url = {https://m2.mtmt.hu/api/publication/34760913}, author = {Bánó, Bálint and Bolotovskiy, Aleksey and Levin, Boris and Mattox, George M.

Although there are some notes on the relationship between scale morphology and ecological needs, in the absence of a sufficiently large and detailed database, the morphological variability of fish scales and the factors responsible for this variability have not yet been explored in detail. For this reason, a database—which contains the shape and relative size data of 193 freshwater fish taxa of 14 orders, originated from five biogeographic realms—has been built. Database analyses showed that both the scale shape and relative size are proper taxonomic indicators. They can be used to separate higher taxonomic categories (e.g., orders), and by the simultaneous analysis of shape and size scale morphology, we showed increased sensitivity for species‐level detachments. Our results suggest that while both the shape and the size of the fish scales are genetically determined, they are also useful descriptors of the niche segregation (habitat use, flow preference) of close relative species. Scale morphology is a promising additional tool to specify the environmental preferences of lesser known or close relative recent and extinct fish species. And also can be of great help in such cases when only the scales are available for taxonomic identification, for example, in the research field of archaeology and palaeontology.}, year = {2024}, eissn = {1467-2979}, pages = {1-20}, orcid-numbers = {Bolotovskiy, Aleksey/0000-0003-2262-6808; Levin, Boris/0000-0002-4044-2036; Mattox, George M.

Our results show that the fish harbour intestinal digesta microbiota that are distinct from that of the surrounding water and that location, domestication status, and host intrinsic factors are strongly associated with the microbiota composition. Furthermore, we show that the vast majority (~97%) of the fish-associated microorganisms do not have any cultured representative.

It is also one of the most famous fish species of Lake Balaton (Hungary), where a unique (genetically separated) pikeperch stock lives. However, until now, no detailed information was available about the pikeperch population genetic structure in Lake Balaton. In the present study, the population genetic structure of the pikeperch assemblages in the lake was revealed by using microsatellite markers. Commercial fishery and angler catch data going back more than 100 years verified that the pikeperch has always been a key element of Lake Balaton’s fish stock utilization. Results of genetic data analyses showed that the pikeperch in the Lake Balaton forms a metapopulation system, in which only the westward stocks show certain separation. Moreover, it seems that the exploitation and mass fish kills that happened in the 1960s and 1970s may have had only a slight impact on the population genetic structure of Balaton pikeperch stocks. The information about genetic features and utilization changes of pikeperch stocks can help to develop area-specific management plans and ensure the long-term survival of this carnivore fish species characteristic of Lake Balaton.}, keywords = {MICROSATELLITE; genetic bottleneck; exploitation; stocking; migration; Angling}, year = {2024}, eissn = {1573-5117}, pages = {559-571}, orcid-numbers = {Zsolnai, Attila/0000-0002-8382-1503; Takács, Péter/0000-0001-5247-7597; Molnár, Tamás Gergely/0000-0003-1752-4268} } @misc{MTMT:34668819, title = {The reference genome of paradise fish (Macropodus opercularis)}, url = {https://m2.mtmt.hu/api/publication/34668819}, author = {Erika, Fodor and Javan, Okendo and Nóra, Szabó and Kata, Szabó and Dávid, Czimer and Anita, Tarján-Rácz and Ildikó, Szeverényi and Bi, Wei Low and Jia, Huan Liew and Sergey, Koren and Arang, Rhie and Orbán, László and Ádám, Miklósi and Máté, Varga and Shawn, M.
