Predavanje je odr\u017eao dr. sc. Davor Zanella, profesor na Prirodoslovno-matemati\u010dkom fakultetu Sveu\u010dili\u0161ta u Zagrebu, voditelj istra\u017eivanja rasprostranjenosti i stanja populacija ciljanih vrsta slatkovodnih riba u NP \u201eKrka\u201c provedenog 2021. i 2022. godine. Trenutno se provodi projekt utvr\u0111ivanja stanja invazivnih vrsta riba na \u0161irem podru\u010dju NP \u201eKrka\u201c.<\/p>\n
Tijek i rezultati navedenih istra\u017eivanja predstavljeni su lokalnom stanovni\u0161tvu, kao va\u017enom partneru kada je rije\u010d o za\u0161titi autohtonog ribljeg fonda i izlovu invazivnih vrsta koje ga ugro\u017eavaju.<\/p>\n
Rijeka Krka spada u vodotoke jadranskog slijeva s najve\u0107im brojem zabilje\u017eenih slatkovodnih vrsta, zbog \u010dega spada u najzanimljivija ihtiolo\u0161ka podru\u010dja Hrvatske, ali i Europe. Istra\u017eivanje je provedeno s ciljem prikupljanja novih podataka o zajednici slatkovodnih riba s obzirom na stani\u0161ta i rasprostranjenost ciljanih vrsta, na temelju kojih \u0107e se izraditi osnova za zoniranje podru\u010dja Ekolo\u0161ke mre\u017ee Natura 2000, a rezultati istra\u017eivanja poslu\u017eit \u0107e i za dono\u0161enje specifi\u010dnih mjera za o\u010duvanje ciljanih vrsta. U istra\u017eivanjima su zabilje\u017eene ukupno dvadeset \u010detiri vrste riba s 12 279 jedinki raspore\u0111enih u \u0161esnaest porodica. Od ukupnog broja zabilje\u017eenih vrsta \u0161est je strano, a osam vrsta jesu zavi\u010dajne endemske vrste: o\u0161trulja, mren, visova\u010dki glavo\u010di\u0107, dalmatinska pijurica, drlja, ilirski klen i turskijev klen. Endemi\u010dne i rijetke slatkovodne ribe, koje su rezultat geolo\u0161ke pro\u0161losti rijeke, uvr\u0161tavaju Krku, u ihtiolo\u0161kom pogledu, u prirodni spomenik najve\u0107e nacionalne i internacionalne vrijednosti. Pra\u0107enje stanja zajednica riba, zavi\u010dajnih i unesenih vrsta, nastavit \u0107e se kako bi se moglo pravovremeno reagirati na promjene stanja i restaurirati pogodna stani\u0161ta.<\/p>\n
Neki od uzroka ugro\u017eenosti slatkovodnih riba jesu pregradnja i regulacija vodotoka, degradacija stani\u0161ta, one\u010di\u0161\u0107enje voda, klimatske promjene i strane i prenesene vrste. Posljednjih godina do\u0161lo je do promjena u ribljem fondu i pojave invazivnih vrsta unesenih iz dunavskog slijeva. NP \u201eKrka\u201c intenzivno radi na njihovu izlovu u suradnji s lokalnim stanovni\u0161tvom.<\/p>\n

[en] The lecture was held by Dr. Davor Zanella, professor at the Faculty of Science, University of Zagreb, head of the project to research the distribution and state of the population of target species of freshwater fishes in Krka National Park conducted during 2021-2022. A second project is currently underway to determine the state of invasive species of fish throughout Krka National Park.<\/p>\n The course of the project and its results were presented to the local population, as an important partner in protecting the indigenous fish fauna, and eradicating the invasive species that threaten them. The Krka River is a watercourse in the Adriatic Basin and contains the highest number of freshwater fish species, making it an interesting ichthyological area in both Croatia and Europe. The research was conducted with the aim of collecting new data on the community of freshwater fish, particularly the habitats and distribution of target species, and these data will be used to develop the basis for zoning areas of Natura 2000 Ecological network, and the results will also serve in adopting specific measures to protect these target species. During the research, a total of 24 fish species with 12,279 individuals belonging to 16 families were recorded. Six alien species were recorded, and eight species are indigenous and endemic: Dalmatian barbel-gudgeon, barbel, Visovac goby, Dalmatian minnow, rudd, Illyrian chub, and Turskyi dace. The endemic and rare freshwater fish species are the result of the river\u2019s geological past, making the Krka a true monument of ichthyology of the highest national and international importance. Monitoring the state of fish communities, indigenous and introduced species, will continue so as to promptly react to changes in the communities and to restore suitable habitats.<\/p>\n Some of the causes of threat to freshwater fish are watercourse regulation and barriers, habitat degradation, water pollution, climate change and alien and translocated species. In recent years, there have been changes to the fish community and the appearance of invasive species introduced from the Danube Basin. Krka National Park is working intensively with the local population to remove these alien species.<\/p>\n <\/p> Javna ustanova \u201eNacionalni park Krka\u201c ju\u010der je u Ispostavi u Skradinu organizirala predavanje za lokalno stanovni\u0161tvo o stanju ihtiofaune na podru\u010dju Nacionalnog parka \u201eKrka\u201c i projektima koji se s tim u vezi provode<\/p>\n","protected":false},"author":3,"featured_media":6742,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[],"class_list":["post-6739","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-novosti"],"_links":{"self":[{"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/posts\/6739","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/comments?post=6739"}],"version-history":[{"count":4,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/posts\/6739\/revisions"}],"predecessor-version":[{"id":13972,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/posts\/6739\/revisions\/13972"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/media\/6742"}],"wp:attachment":[{"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/media?parent=6739"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/categories?post=6739"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/npkrka.hr\/hr\/wp-json\/wp\/v2\/tags?post=6739"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
