LABUST has taken part in many scientific research projects relating to underwater systems and technologies in various roles. This includes numerous international (FP7, H2020, ONRG, INTERREG,...) as well as national projects.
Laboratory for Underwater Systems and Technologies (LABUST), CoE MARBLE, and IEEE OES University of Zagreb Student Branch Chapter invite you to a talk "Research on Freshwater Fish in Deep River Habitats" held by Prof. Marko Ćaleta, Professor at the University of Zagreb Faculty of Teacher Education, and Faculty of Science, as part of the MARBLE project.
The lecture will take place on Friday, November 28th, 2025 at 11:30 a.m. at LABUST lab (Miramarska cesta 20). The lecture will be held in person in English language and is estimated to last 60 minutes, including questions.
A short biography of the lecturer and summary of the lecture can be found below.
Bio:
Marko Ćaleta, born in 1976 in Zagreb, earned his BSc in Biology-Ecology from the University of Zagreb's Faculty of Science in 2000 and his PhD in 2007. From 2000 to 2011 he worked as a research assistant at the Faculty's Division of Zoology on national fish-community projects. Since 2012 he has been a full professor (2022) at the Faculty of Teacher Education, teaching natural sciences and leading the Mammalogy course at the Biology Department. His research centers on Croatia's freshwater fish, especially in the Sava River and Dinaric karst, focusing on ecology, rare and endemic species, and invasives. He has co-authored 5 books, 5 chapters, over 70 peer-reviewed papers, and more than 50 conference presentations. Prof Ćaleta has contributed to three national and numerous international projects, including the Joint Danube Surveys (2007–2025), Water Framework Directive, and NATURA 2000 initiatives. A member of Croatian and European biological and ichthyological societies, he has held key faculty roles: chair of quality management, department head, vice-dean, ethics committee member, and since 2024 vice-chair of the Interdisciplinary Scientific Committee.
Abstract:
Research on Freshwater Fish in Deep River Habitats
Freshwater fish utilize various types of habitats, ranging from still to flowing waters, river and floodplain habitats, upper (upstream) and lower (downstream) river sections, as well as surface and near-bottom habitats. The vertical distribution and abundance of species and individuals within the water column represent one of the greatest challenges in freshwater fish research. Near-bottom habitats of large rivers are highly important and attractive to many fish species and their developmental stages during different times of the day and year. However, due to their isolation and inaccessibility, they are the most difficult to study using standard ichthyological methods and represent the least known river habitats.
