Abstract
Kisik je plin neophodan za održavanje i razvoj gotovo svih živih organizama jer sudjeluje u mnogim biokemijskim procesima. U more dolazi difuzijom iz zraka i fotosintezom vodenih algi i viših biljaka, a oba procesa ograničena su na površinske slojeve pa su oni i najbogatiji kisikom.U kaveznom uzgoju, koncentracija kisika u samom kavezu može pasti, zbog procesa disanja riba, ukoliko morsko strujanje ne osigurava prinos dovoljne količine svježe vode sa dovoljno otopljenog kisika. Istraživanje je... More provedeno monitoringom na uzgajalištu „Kali Tuna“ pod Mrđinom, a rezultati istraživanja dobiveni su laboratorijskim određivanjem koncentracije otopljenog kisika metodom po Winkleru. Cilj ovoga rada bio je analiza režima kisika u kaveznom uzgoju monitoringom uzgajališta „Kali Tuna“ pod Mrđinom. Rezultati istraživanja su pokazali da je najveća koncentracija kisika prisutna na dubinama od 10 i 20 metara, te da se koncentracija kisika postepeno povećava od morskog dna do 20 metara dubine, a poviše 10 metara dubine počinje lagani pad koncentracije kisika.

Abstract (english)
Oxygen is gas essential for maintenance and development of almost all living organisms because it participates in many biochemical processes. It comes with diffusion from the air into the sea by photosynthesis of water algae and higher plants. Both processes are limited to surface layers, so they are the richest in oxygen. In the cage fish farming oxygen concentration may fall due to the breathing of fish if the sea current does not provide yield a sufficient amount of fresh water with enough... More dissolved oxygen. The survey was conducted by monitoring on the fish farm „Kali Tuna“ under Mrđina, and the results of the research were obtained by laboratory determination of the dissolved oxygen concentration, method by Winkler. The results of this research have shown that the highest oxygen concentration is present at depths of 10 and 20 meters depth, and the oxygen concentration gradually increases from the sea bottom to 20 meters in depth, and under 10 meters deepth begins a lower oxygen concentration.
