The oxygen balance of the Crnojevica river water [Montenegro, Yugoslavia]
2001
Djuraskovic, P. | Tomic, N. (Republicki hidrometeoroloski zavod, Podgorica (Yugoslavia))
The balance of production and respiration processes in water of Crnojevica river (Montenegro, Yugoslavia) has been estimate, over the estimate correlation between significant parameters of water quality (BOD, % saturation of O2, pH). Correlation between these parameters is established. The balances exist in stationary conditions. But, impact of precipitation is disturbing this state. The hydrodynamic conditions at underground flow and wastewater effluent from the town Cetinje area, has been influence for it, too. The data are referring to small and middle water state.

Macic, V. (Institut za biologiju mora, Kotor (Yugoslavia)) | Sekulic, P. (Naucni institut za ratarstvo i povrtarstvo, Novi Sad (Yugoslavia))
In order to determinate the concentration of elements: K, Ca, Na, Mg, Cu, Pb, Cr, and Cd in sea water and seagrasses Posidonia oceanica and Cymodocea nodosa sampling were done in the area of the Boka Kotorska Bay (Adriatic sea, Montenegro (Yugoslavia)). For majority of these elements variability of contents in the samples was great, but in the range of expectations. The concentrations of Pb and Cr in the seagrasses were higher from values in literature. Because of bioaccumulation and biomagnification of these metals, we have to investigate causes of these higher concentrations and possibility of toxic effects on the seagrasses and other organisms.

2001
Stojiljkovic, D. (Poljoprivredni fakultet, Novi Sad (Yugoslavia). Institut za uredjenje voda)
Water quality is a main precondition for use in water supply and bottling. In this paper, a review of Yugoslavian standard referring to maximum allowed concentration of some components, as well as a review of some components contents in prohibited concentrations in Yugoslav and foreign bottling drinking and mineral waters are presented.

2001
Talevski, T. (Hidrobioloski zavod, Ohrid (The Former Yugoslav Republic of Macedonia))
In this paper are presented the length and weight growth of carp (Cyprinus carpio L.) from artificial lake Slatino (The Former Yugoslav Republic of Macedonia). Artificial lake Slatino because some recontruction works was whole emplied in 1993. Than all fish population was leaved in the river Mramorechka. Artificial lake Slatino has been stocking with individuals of carp (Cyprinus carpio L.) catch from Lake Ohrid. They are used for reproduction and in first years were used for reparation of the fish fond in artificial lake.

2001
Stanisavljevic, M. | Krstic, I. (Fakultet zastite na radu, Nis (Yugoslavia). Smer zastite zivotne sredine)
The purpose of this work is finding a solution to the brewery wastewater refining problem. As a result, a preliminary treatment for wastewater emission in the town sewage is given. For huge ecological recipients demands, a possibility of the complete refining is presented. After giving the analysis, conceptions for solutions to recycling plants are displayed. The contribution of this paper is in solving the problem of the treatment of the wastewater generated during technological process of beer production and is based on several years investigation.

Autochthonous and alochthonous fish species in lake Ohrid and its catchement area [The Former Yugoslav Republic of Macedonia]
2001
Talevski, T. (Hidrobioloski zavod, Ohrid (The Former Yugoslav Republic of Macedonia))
In this paper are presented autochthonous and all other alochthonous famous fishes in Lake Ohrid and its catchement area (The Former Yugoslav Republic of Macedonia). Introduction of new species in lakes and rivers in the Former Yugoslav Republic of Macedonia is prohibited, especially in Lake Ohrid and catchement area. The most probable period and possible way of introduction are presented and the reason of that introduction, as well. It is necessary, in the future, more attention to be paid on Lake Ohrid protection from introduction of new species, which may cause big changes in Lake Ohrid dynamics.

Oligochaeta community of "Kapetanski rit" fish pond [Serbia, Yugoslavia]
2001
Mrkic, B. | Dulic, S. (Zavod za zastitu zdravlja, Subotica (Yugoslavia))
During the period May - September 2000, the structure of quality and quantity of Oligochaeta community was investigated on three locations of "Kapetanski rit" fish pond (Serbia, Yugoslavia). At same time were determined some physical and chemical parameters of water temperature, pH value and concentration of dissolved oxygen. In that period of time, the location of Divlje jezero there was no presence of Oligochaeta community. The location of Novo jezero was characterized by 6 species from two families - Naididae and Tubificidae, and the location of Veliko jezero was characterized by only three species. The results from Veliko and Novo jezero show differences in proportional presence and quantity characteristics.
