High-throughput discrimination of bacteria isolated from Astacus astacus and Astacus leptodactylus

2013
Bacterial diseases and pathogens of crayfish are common, widespread, and occasionally causing serious mortalities. In order to take rapid measures for correct treatment of crayfish diseases, the turnover time and accuracy in bacterial identification is an issue. Bacteria isolated from tissues of apparently healthy Astacus astacus and A.

Aquaculture of juvenile Astacus astacus in a greenhouse

2013
Our recent research revealed more than 36% decline in the number of Croatian populations of noble crayfish when compared to historical data. Such alarming negative trend requires immediate conservation activities where restocking and stocking of the available freshwater ecosystems with noble crayfish from remaining populations is an important part. For

Mogućnosti uzgoja potočnog raka (Astacus astacus)

2004
Predavanje na temu očuvanja autohtone vrste riječnog raka, koji sve brže nestaje iz naših vodotoka zbog porasta zagađenja, pojave bolesti (račja kuga) i neprirodne kompeticije s alohtonim vrstama. Najučinkovitija metoda zaštite je uzgoj u kontroliranim uvjetima te repopulacija uzgojenih jedinki u prirodna staništa.

RIJEČNI RAK (Astacus astacus L.) NA PODRUČJU NP PAKLENICA

2002
Imajući u vidu činjenicu da se ne zna mnogo o biologiji i ekologiji rakova u našim vodenim ekosustavima te da je nalazište vrste A. astacus u potoku Velika Paklenica neočekivano (zna se da je u rijekama Jadranskog sliva rasprostranjena vrsta A. pallipes), glavna svrha ovog projekta je bila istražiti dinamiku populacije (veličina i gustoća populacije ...
