AB  - The success of production in aquaculture depends on the water quality, the fish fry but also on the skillfulness of the producers in achieving a profitable production while applying the most optimal technology. One of the producer's dilemmas, when applying feed, is the dynamics of supplemental feeding of fish. This was the reason for carrying out an experiment at the laboratory for fish nutrition at the Faculty of Agriculture, University of Belgrade (Serbia). In three experimental groups, during 60 days, carp weight in correlation to the dynamics of feeding was studied. For the first group, feed was available to fish once a day, during 60 min, the second group had feed available twice a day, during 60 min, and the third group had feed available during 12 hours continuously. The results showed that there was a significant difference in the weight between the three experimental groups. The weight of fish from the first group was 41.47%, for the second group was 50.42%, and for the third 87.79%, respectfully, in relation to the stocking ichthyomass. According to the t-test the average weight of the first and second group was not statistically different but they were very significantly lower from the average weight of fish that had feed available 12 hours daily.

AB  - In the era of growing demand for sustainable usage of water, all types of aquaculture systems are under reconsideration. Until recently semi-intensive production was concerned to be one of the least polluting. Nowadays, this fact has been reassessed especially in many countries culturing carp in this way. One of the most significant influences on a fish pond ecosystem in semi-intensive carp production is changing its characteristics by adding low quality supplemental feeding. Therefore, the type of fish feed, its physical and chemical characteristics can considerably change the water quality of a fish pond. Aiming to analyze the effect of commonly used feeds (cereals, pelleted and extruded feed) in semi-intensive production on the water quality, an experiment was carried out at three fish ponds during one production season. Even though the results of physical, chemical and biological parameters showed that there were no statistically significant differences in the water quality between fish ponds with different supplemental feed, looking at the overall picture it could be concluded that the pond that had the lowest quality of feed (row cereals), having high organic mater and chlorophyll a during most of the trial period as well as the specific phytoplankton successions including potentially harmful blue-green alga, had consequently the lowest water quality.

AB  - Fishery in Serbia comprises of aquaculture and fishery. 
Aquaculture in Serbia concerns fish culturing. For production of other aquatic animals, mainly ornamental plants and crayfish, only occasional interest and small scale production in aquarium type of units exists. Fish are produced in carp and trout fish farms (over 95%), to a smaller extent in cages, enclosed or partitioned natural or man made aquatic ecosystems. Aquaria fish culture is mainly low scale, with a small number of specialized breeders and one public aquarium (M a r k o v i ć i M i t r o v i ć T u t u n d ž i ć, 2003, 2005; M a r k o v i ć i P o l e k s i ć, 2007, M a r k o v i ć i sar., 2009).
In Serbia freshwater species cultured are: common carp, white and gray bighead, wells, pike perch, rainbow trout and to a lesser degree Northern pike, tench, brown trout, beluga, Russian starlet.
There is 13 500 – 14 000 ha of fish farms in Serbia, with 99.9% of carp farms and 0.1% of trout farms. The total fish production in recent years is between 10 000 and 15 000 tons with 70 to 75% of consumable fish.
All three types of production systems are present: extensive, semi-intensive and intensive. Extensive production is sporadic and is present only at a few carp production units, mostly not economic for semi-intensive production due to remoteness from other production units or neglect. The principal type of production (75 – 80%) is semi-intensive production of cyprinids, with common carp as the main species. Common carp is present with more than 80% of the total production in warmwater fish farms. The traditional (old) type of feeding is slowly changing. Cereals are more often, at over 50% of production surfaces, totally of partially replaced by complete, peletted and even more extruded feed. This has resulted in an increase of production per surface unit in recent years. Intensive production systems in carp culture are less present, at a small number of earthen ponds with aeration systems, mainly for fish fry production, and in cages. However, rainbow trout, the only salmonid species cultured for consummation, is exclusively produced in intensive systems at trout farms in Serbia.
	The number of people involved full-time in fish production in Serbia is about 1100 and approximately 400 seasonal workers that are hired mainly prior to harvest. 
	With the rising of standard and returning to traditional habits during religious fasting, as well as with a slow increase of “healthy food” supporters, fish consumption has a growing trend. However, although fish production is increasing in recent years, the country’s production and open-water capture fishery barely represent a quarter of the total needs of inhabitants. This results in increase of import, mainly marine and frizzed fish, but also freshwater fish.  
	Open-water capture fishery is performed in Serbia’s fishing waters. They are represented by 66 000 km of water currents (rivers and streams), flood plains, backwaters, 50 lakes, 150 reservoir lakes and around 30 000 km of canal systems, hydromeliorative systems, as well as all other waters with fish. All fishing waters are divided into 6 fishing regions (Serbia – Vojvodina, Serbia – West, Serbia – South West, Srbia - South, Serbia – East, Serbia – Center) since year 2007. Sports fishing is obtainable at all regions but commercial fishery is aloud only at two regions  (Serbia – Vojvodina, Serbia – west), and in rivers Tisa, Sava and Danube. Number of fisherman with purchased license in the last couple of years is between 50 000 and 100 000. Number of commercial fishermen is between 500 and 2000 in the last ten years. The amount of captured fish is between 2000 and 3000 tons in the few past years.

AB  - Selective breeding for growth rate in common carp (Cyprinus carpio L.) has not been actively pursued after some early unsuccessful selection experiments. Prerequisite for successful selective breeding is accurate and objective evaluation of genetic parameters used in the planning and implementation of selection methods. The aim of this work was to assess the possibilities of improving production traits (weight, length and height) that are related to the growth of carp, through selection. Estimated variation and heritabilities were significantly high for all examined characteristics. Based on the obtained results can be expected to improve growth rate of common carp through selective breeding.

Although common carp is a popular experimental fish, contradictory results on protein requirement have been reported by different works. An experiment lasting for 3 months included different protein level in 4 diets: 38.1%, 38.5%, 41.5% and 43.7%. Carp yearlings (body mass 95.5g) were fed in order to investigate effects on growth rate. There were no significant differences in the final individual weights, weight gains, specific growth rates (SGR), feed conversion rate (FCR) and thermal growth coefficient (TGC) among fish fed different diets (P>0.05).

AB  - Assessment of water quality at Radmilovac estate near Belgrade that is used for irrigation of cultures and as a water supply for experimental fish farm and hatchery was performed by using aquatic invertebrates (zooplankton and macrozoobenthos) and fish gill histology as bioindicators. Two open wells and a stream were monitored during a three year investigation. A total of 25 and 31 species of zooplankton were found in open wells and 11 and 12 taxa of macrozoobenthos at two sites of stream Sugavac. The saprobity index (S) was used to evaluate the water quality of these four sites. Statistical analysis showed that site S2 was the most polluted, with Oligochaeta and Chironomidae larvae dominating. Overall, beta mesosaprobic organisms have been prevailing at all four sites indicating that the water was polluted at moderate levels. All analyzed fish gills showed predominantly normal structure. Identified histopathological changes of gill structure indicated mild and reparable alterations. The results obtained imply that these water resources can be used as a supply for carp fish farm. We suggest that the type of biological water assessment depends on waterbodies characteristics.

AB  - During the period from April to October in the production season of the year 2000, seven chemical parameters of the aquatic environment were analyzed twice a month for the amount of natural food (zooplankton and bottom fauna) on pond No. 4 at the Dubica Carp Farm in Banatska Dubica (Vojvodina, Serbia). Correlation between natural food and carp growth was analyzed as well. The investigations revealed negative correlation between the amount of natural food per kilogram of ichthyomass and pH (p  lt  0.001, r = -0.875), electroconductivity (p = 0.0294, r = -0.673), COD (p = 0.0052, r = -0.782), total water hardness (p = 0.0186, r = -0.709), and carbonate water hardness (p = 0.0087, r = -0.758). However, statistically significant positive correlation was found between the biomass of natural food (g/kg of ichthyomass) and concentration of nitrates (p  lt  0.01, r = 0.841) and phosphates (p = 0.0427, r = 0.640). Concerning com­ponents of natural food (zooplankton and bottom fauna), bottom fauna biomass had a very low production and showed no statistically significant correlation (p = 0.137, r = 0.491) with total natural food biomass whereas zooplankton biomass was very significantly correlated (p lt 0.001, r = 0.830) with the total amount of natural food, indicating that zooplankton was the dominant component of natural food at the investigated fish pond. The daily weight gain (%) of cultured fish was greatest at the beginning of the carp farming season, i.e., in April, when it comprised a value of 2.3%. After negative growth at the end of May (-0.2%), a gradual increase of weight gain was recorded until the beginning of September. By comparing the biomass of natural food with the daily weight gain (%) of carp, it was observed that the weight gain had a trend similar to biomass of natural food with a 15 day interval. This relationship was justified by positive statistical correlation (p = 0.006, R = 0.960). As zooplankton was the major component of natural food, fish relayed on it as the main protein source showed by a significant positive correlation (p = 0.034, r = 0.907).
AB  - U toku proizvodne sezone 2000. godine, u periodu od aprila do septembra, dva puta mesečno, vršena je analiza sedam hemijskih činioca vodene sredine u korelaciji sa dinamikom prirodne hrane (zooplanktona i faune dna), kao i korelacija između prirodne hrane i dinamike rasta šarana u ribnjačkom objektu br. 4, šaranskog ribnjaka 'Dubica' iz Banatske Dubice, Srbija. Istraživanja su pokazala negativnu korelaciju između: pH (p lt 0,001, k=-0,875), elektro­provodljivosti (p=0,0294, k=-0,673), HPK (p=0,0052, k=-0,782), ukupne tvrdoće vode (p=0,0186, k=-0,709), karbonatne tvrdoću vode (p=0,0087, k=-0,758) i količine prirodne hrane (zooplanktona i faune dna) iskazane po kilogramu ihtiomase. Statistički značajna pozitivna korelacija konstatovana je između koncentracije nitrata (p lt 0,001, k=0,841) i ortofosfata u vodi (p=0,0427, k=0,640) i količine prirodne hrane po kilogramu ihtiomase. Posmatrajući odnos komponenti prirodne hrane: zooplanktona i faune dna prema ukupnoj količini prirodne hrane, bio­masa faune dna ne pokazuje statističku značajnu korelaciju (p=0,137, k=0,491) sa ukupnom biomasom prirodne hrane po kilogramu ihtiomase, dok biomasa zooplanktona pokazuje značajnu korelaciju (p lt 0,001, k=0,830) sa ukupnom količinom prirodne hrane (izražene po kilogramu ihtio­mase), a što ukazuje na činjenicu da je u ispitivanom ribnjaku dominantna komponenta prirodne hrane zooplankton. Dnevni procentualni prirast gajene ribe bio je najveći početkom sezone gajenja šarana tj. u aprilu -2.3%. Posle negativnog prirasta krajem maja (-0.2%), zabeležen je postepeno povećanje prirasta sve do početka septembra. Komparacijom biomase prirodne hrane (izražene po kilogramu ihtiomase) i procentualnog dnevnog prirasta šarana, konstatovano je da prirast šarana najčešće prati količinu prirodne hrane, tako što se beleži povećanje prirasta 15 dana nakon povećanja bio­mase takve hrane.

AB  - The species Helicopsyche bacescui in Europe has a disjunct area that is mainly situated south of 45 degrees N latitude and east of 22 degrees E longitude with an isolated smaller part in southwestern Hungary. Recent investigations on the territory of Serbia documented the presence of H. bacescui at 39 localities south of the Danube. The known area of the species is thereby enlarged by about 30%, while its western boundary is relocated by about 440 km. H. bacescui is primarily found in lowlands at elevations of less than 200 m above sea level, frequently in streams that periodically run dry. In Serbia, on the other hand, it is found in permanent highland streams at localities with average elevation of 467 +/- 35 m above sea level. The highest locality at which this species has been found is the spring of the Obudojevica (Western Serbia), which lies at an elevation of 1060 m above sea level. H. bacescui belongs to specific benthic communities that differ from typical macrozoobenthos assemblages found in similar habitats in Serbia by the pronounced dominance of Gammaridae, significant presence of Pisidium species, and absence of other groups of Trichoptera (above all, members of the family Hydropsychidae).
