Abstract

U radu su prikazani opći podaci o rakovima iz porodice Astacidae (Crustace/Decapoda), koji su zakonom zaštićeni u Hrvatskoj, njihovoj raznovrsnosti, morfologiji, biologiji i ekologiji. Posebna pažnja je posvećena vrstama Astacus astacus (Linnaeus, 1758) i Austropotamobius pallipes (Lereboullet, 1858) koje su uvrštene u Crveni popis ugroženih svojti Međunarodne unije za očuvanje prirode (International Union for Conservation of Nature – IUCN), a čiji se eksperimentalni uzgoj uspješno obavlja u „Hrvatskom centru za autohtone vrste riba i rakova krških voda – Otočac“ u Ličkom Lešću na izvoru Kostelka.
Centar je još 2009. godine započeo s eksperimentalnim uzgojem riječnog raka Astacus astacus pri čemu su utvrđeni pogodni uvjeti za život i razmnožavanje rakova u vodi. Projekt „Uzgoj i repopulacija riječnog raka Astacus astacus i bjelonogog raka Austropotamobius pallipes“ započeo je 2012. godine i za početak je bio usmjeren samo na riječnog raka, a rezultirao je izvaljivanjem 1509 račića. Novi projekt pod nazivom „Optimiziranje ubrzanog uzgoja ličinki riječnog raka Astacus astacus“ je počeo u 2014. Nakon dobrih rezultata u uzgoju riječnog raka u jesen 2015. godine započeo je projekt „Optimiziranje ubrzanog uzgoja ličinki bjelonogog raka Austropotamobius pallipes“ koji je također bio uspješan i u proljeće 2016. su po prvi puta u Centru izvaljeni i bjelonogi račići.

Abstract (english)

This work presents general information about Astacidae family of crayfish (Crustace/Decapoda), who are protected by law in Croatia, and their diversity, morphology, biology and ecology. Special attention is given to Astacus astacus (Linnaeus, 1758) and Austropotamobius pallipes (Lereboullet, 1858) who are included in the Red List of threatened species of International Union for Conservation of Nature (IUCN) and successfully experimentally cultivated in „Croatian Centre for Local Fish and Crayfish of KarstWater – Otočac“ in Ličko Lešće on the Kostelka spring.
In the year 2009, Centre has begun with the experimental cultivation of noble crayfish Astacus astacus resulting in established suitable conditions for life and reproduction of crayfish in water. The project „Cultivation and repopulation of the noble crayfish Astacus astacus and the white-clawed crayfish Austropotamobius pallipes“ began in 2012 with the aim just to analyse the noble crayfish but in the end the project resulted in reproduction of 1509 crayfish. The new project called „Optimization of accelerated cultivation of the noble crayfish larva Astacus astacus“ began in 2014. As the cultivation of the noble crayfish project showed good results, the new project of „Optimization of accelerated cultivation of the white-clawed crayfish larva Austropotamobius pallipes“ has been established in the fall of 2015 and also proved successful with the outcome of reproducing white-clawed crayfish in the spring of 2016 for the first time ever in the Centre.
