In the structure of herbivorous fish the grass carp is leading with 64,28%, followed by the big head carp with 26.02% and the silver carp with 9.70%. Compared to the previous year the production of the trout and tench has somewhat increased, while the production of all the other species of fish has decreased. Fish catch in open waters has increased by 19.23% in comparison to the previous year. In the production and catch of the total freshwater fish, carp made up 77.46%, the herbivorous fish made up 4.32%, trout 4.32%, sheat fish, pike perch and pike 2.99% and all other fish species 7.36%. As far as the distribution of production and catch is concerned, 46.91% were sold on the market, 39.19% were used for reproduction (stocking the fish farms), mortalities were 6.23%, and for personal use (sports fishing) 7.67% was used. The number of fisheries workers has decreased by 17.75%, and the production per worker has also decreased by 26.62%, compared to the previous year. Average production per worker was 5.87 tons of fish.

The surface area used for production of fish has decreased by 274 ha or 2,51%. The total amount of fish has decreased by 1.263 tons or 14,78%. The highest production of fish was reached by the fish farm Donji Miholjac with 1.231 kg/ha. The feeding coefficient is 3,10 kg. Only on one fish farm was the feeding coefficient less than 2.0 kg (1,40 and on two large farms this coefficient was greater than 5,00 kg. The main fish food is still wheat followed by corn. The amount of fertilizer used was decreased by 14,40%. The fry carp growing ponds make up 0,92% of the surface area of the entire fish farm, the young carp ponds 21,77% and the culturing ponds for consumption fish 76,55%. The total amount of fish in the carp ponds was 660 kg/ha, and in the trout ponds it was 123.4 tons/ha. The carp is the highest produced fish with 80, 35%, then the herbivorous fish with 5,65 and all other fish make up 14% of the total production. In the structure of herbivorous fish the grass carp is leading with 54, 70%, followed by the big head carp with 25,54% and the silver carp with 19,76%. In comparison with the previous year the production of "all other fish- has significantly increased (287%), and sheat fish 18,90%, while the production of trench has decreased (71%).

Hydrogeology of Gradi nica and Ga pinova jama caves in karst aquifer between Planinsko polje and Ljubljanica Springs (Central Slovenia)
Janez turk
Geologija , 2008,
Abstract: Underground karst water is accessible only in two caves near Logatec town (30 km south of Ljubljana, central Slovenia); Gradi nica and Ga pinova jama caves. Water level and water temperature were continuously measured more than one year in both caves. Gradi nica and Ga pinova jama caves belong to the same karst aquifer, therefore fluctuations of water level are almost identical and simultaneous.According to our measurements,fluctuations are significant;they rach at least 50 m.Incontrast,water temperature is significantly different at both locations.Mean difference is 1-2 °C, the highest measured was 5 °C. Relatively high temperature differences are due to recharge characteristics of the aquifer. It is fed by waters which have different surface origin. Water temperature in Gradi nica Cave directly reflects temperatureof the surface Unica River at medium water condition. On the contrary, the Unica River influences on water temperature in Ga pinova jama Cave at the highest floods only.Ithappens when discharge of the surface Unica River at Haasberg exceeds 40 m3/s. Water temperature becomes similarin larger part of the aquifer between both discussed caves, at such high water conditions only. Temperature of underground water tells us much about the origin of the water, which feeds discussed caves.
Identification of depositional hiatuses in karst infillings – Example from Divje babe I cave (Slovenia)
Janez Turk
Geologija , 2011,
Abstract: The Divje babe I cave is world known Paleolithic site in western Slovenia. In this paper, special interest is given to the identification of sedimentary hiatuses in karst infillings. Hiatuses can be the most reliably identified by detailed radiometric dating throughout the profile. However, this method is very expensive from economical point of view. New approach was developed in Divje babe I cave. Study of morphological characteristics of clast, may revealthe position of hiatuses. Four presumable hiatuses were assessed in sedimentary profile ranging from depth - 281 cmto - 481 cm below the contemporary ground floor in Divje babe I cave. Two hiatuses can be confirmed by results of radiometric datings, but another two hiatuses are doubtful. However, the identification of hiatuses by radiometric dating greatly depends on vertical length between two dated levels. Larger the length, greater the probability that hiatus was overlooked. Reliability of two presumable hiatuses can be confirmed by additional radiometric datings or with another analysis, such as measurement of degree of weathering.
Od Taylorja do Druckerja: management in manageriranje = From Taylor to Drucker: Management and Managing
Primoz Turk
Management , 2008,
Abstract: The article discusses the question of management and managing, focusing on the changes which took place in the period from Taylor to Drucker. In this period two turning points dramatically changed the nature of management. Management which started within the organization was at first concerned with the organization’s inner workings. This concern with the organization’s ‘inside’ is gradually projected to the outside, to society as a whole. Simultaneously, changes occur in managing. Managing which was first understood as managing others, i.e. as the activity of the manager managing the worker, changed into managing oneself. This is a shift to the inside, to managing individual’s inner world and thinking processes.

Ackerages used for the fish production have been increased 6 ha or 0,66%. The total fish amount was bigger for 462 tons, or 10,04%. The feeding coefficient is 3,8 kg 46,15% bigger compared to the previous year. The amount of the fertilizer used has decreased by 11,45%. The fry carp growing ponds make up 1,39% of the total fish pond surfaces, the yung carp ponds 19.92%, and the ponds with consumption fish 77,76%. The total amount in the carp ponds with consumption fish 77,76%. The total amount in the carp ponds was 522 kg/ha, and in the trout ponds it was 110,4 tons/ha. The most produced fish species is the carp with 79,04% followed the herbivorous fish with 10,42%, the trout with 5,89%, while all the other fish species make up 4,65% of the entire production. In the structure of herbivorous fish the big head carp with 57,57%, followed by the grass carp with 37,31% and the silver carp with 5,12%. Compared to the previous year the production herbivorous fish, the sheat fish, the pike and young carp, while the production the trout. Fish catch in open waters this year not in the files in statisc. The number of fisheries workers has decreased for 5,77%, and the production per worker is bigger for 16,74% compared to the previous year. Average production per worker was 8,38 tons of fish.

Ribarstvo : Croatian Journal of Fisheries , 1996,
Abstract: The data on the production and catch of fish according to sorts, pond ackerage, fishing means as well as the distribution of production and catch in 1995 have been stated in the paper. Ackerages used for the fish production have been increased by 1710 acres or 6.51%; total fish prinos* is less for 1,252 tons or 17.05%. The highest production of fish was reched by the fish farm Donji Miholjac with 859 kg/ha. A nutritive coefficient is 3.0 kg and it is less by 3.22% compared with the previous year. The nutritive coefficient is less than 2.0 kg in three fish-farms but it is greater than 4.0 kg in five large fish farms. Mostly corn but also wheat dominate in fish nutrition. The fertilizers consumption has been reduced by 14.53%. Of total pond ackerage, growing fish farms occupy 1.25%, new fish farms occupy 17.90% and consumptive fish farms occupy 79.64%. Total fish production in carp ponds is 507 kg/ha and 136.1 ton/ha in trout ponds. With 84.33%, carp is the mostly produced fish sorts, herbivore fish follow it with 3.89% and the production of all other fish makes 11.78% of the total. With 83.97%, grass carp takes the first place in the structure of herbivore fish. It is followed by the big head carp with 9.28% and silver carp with 6.75%. The trout production has been slightly increased by 6. 3%. Pike has appeared again and all other fish sorts has been reduced. Fish catch in open water has been increased by 7.06% compared with the previous year. When we sum up total production and catch of fresh-water fish, we can conclude that carp contributes with 81.08%; herbivore fish with 3.67%; trouts with 5.53%; sheat-fish, pike-perch and pike with 2.74% and all other fish sorts with 6.98%. As to the distribution of production and catch, there has been 49.02% sold on markets, 38.02% has been spent on farm reproduction (set back in ponds), the percentage of mortalities is 7.90%. Sport fishers have spent 5.06% of fish. The number of employees has been reduced by 12.05% and fish production per employee has also been reduced by 1.10% compared with the previous year. It has been produced 8.0 tons of fish per employee. In 1995, the production has been greatest in Dragani i: 15.60 tons of fish per employee.
