The aim of this research paper is to present available data on the distribution of freshwater crayfish in Bosnia and Herzegovina, including data from the literature and those of our own ...investigations. According to historical data, the existence of four native European species were reported within the territory of Bosnia and Herzegovina: Astacus astacus (Linnaeus, 1758), A. leptodactylus (Eschscholtz, 1823), Austropotamobius torrentium (Schrank, 1803) and A. pallipes (Lereboullet, 1858). Our recent research has confirmed the presence of these four species. A. torrentium has been found in the tributaries of the rivers Bosna and Una, in ecologically similar habitats, that is, in relatively clean waters with a small amount of organic material (water quality category I or II). A. pallipes is predominantly present in the Neretva River basin, partly in the Una River basin and in the Cetina River basin, forming both river and lake populations (in the Boracko Lake are present in particularly large numbers) – waters with oxygen concentrations greater than 9 mg·L-1 and BOD5 values less than 2 mg·L-1. A. astacus is present in a dense population in waters of the Drina River basin (as river and lake populations), but occurs also in the tributaries of the rivers Bosna (midstream) and Sava. So far, A. leptodactylus was found only at the two localities: Sava River (Brčko area) and Miljacka River (upstream of Sarajevo), in the waters quality of category II (beta-mesosaprobic). Allochthonous species have not been yet recorded in the freshwater habitats of Bosnia and Herzegovina.
Le but de cet article est de synthétiser les données disponibles sur la distribution des écrevisses d’eau douce en Bosnie-Herzégovine, en regroupant les données de la littérature et celles de nos propres investigations. Selon les données historiques, l’existence de quatre espèces indigènes est rapportée sur le territoire de Bosnie-Herzégovine : Astacus astacus (Linnaeus, 1758), A. leptodactylus (Eschscholtz, 1823), Austropotamobius torrentium (Schrank, 1803) et A. pallipes (Lereboullet, 1858). Nos travaux ont confirmé la présence de ces quatre espèces. A. torrentium a été trouvée dans les tributaires des rivières Bosna et Una, dans des habitats semblables, c’est-à-dire dans des eaux claires avec peu de charge en matière organique (classe de qualité d’eau I ou II). A. pallipes est surtout présente dans le bassin de la rivière Neretva, en partie dans le bassin de la rivière Una, et dans celui de la rivière Cetina, avec des populations en rivière et en lac (particulièrement abondante dans le lac Boracko) aux eaux à des concentrations supérieures à 9 mg·L-1 et des valeurs de BOD5 inférieures à 2 mg·L-1. A. astacus est présente en populations abondantes dans le basin de la rivière Drina (en lac et en rivière), et également dans les tributaires des rivières Bosna (partie médiane) et Sava. Pour l’instant A. leptodactylus a été trouvée dans seulement deux localités : rivière Sava (région de Brčko) et Miljacka (amont de Sarajevo), dans des eaux de qualité II (beta-mésosaprobique). Aucune espèce introduite n’a pour l’instant été inventoriée dans les habitats d’eau douce de Bosnie-Herzégovine.
The analysis of content of a pikeperch Stizostedion lucioperca gastro-intestine system was done on the basis of examination of contents of gastro-intestine systems of 27 specimens captured in the ...accumulations of the river Neretva system. The fish capture was done using the nets set by the members of Ichthyology and Fishing Center at the Faculty of Science Sarajevo, in the period between 17. 07 - 24. 09. 2002. The dissection and fixation of gastro-intestine systems using the 4 % formaldehyde were done on the terrain. The examination of their contents was done in the laboratory of the Faculty of Science Sarajevo. The appearance of a pikeperch in the river Neretva system is result of an accident introduction in the lake Rama (S k r i j e l j, 1995; S k r i j e l j and Ma s o v i c, 2001). The analysis results of the contents of a pikeperch gastrointestine system have indicated very various way of its nutrition caused by capacity of a water ecosystem and a specimen size. Its tendency to the nutrition with the other fish species is expressive in the lakes with the bigger competition with the other fish species and its tendency to cannibalism is expressive in the hydro-accumulations (Salakovac and Mostar). The cannibalism has characterized a pikeperch specimens larger than 30 cm. The specimens in the lake Grabovica (4), shorter than 30 cm, ate the specimens of the zoobenthos settlement. The algae are registered in stomach of one specimen. The survival of important autochthonous species of salmonoids and cyprinids has been endangered because of the established expressive greed of a pikeperch (the larger size specimens). This fact has caused larger negative ecological changes in the central water current of the river Neretva system. These conditions require the measures of control of a pikeperch population density and introduction in general. Comparison of the nutrition of this fish species with the others in the river Neretva accumulations (K a c a n s k i et al., 1976; T r o z i c - B o r o v a c, 2002a), it could be concluded that a pikeperch has no competitor. The other fish species have fed on the invertebrates and plants of benthos, accept a rare lake trout Salmo trutta m. lacustris Linnaeus, 1758 specimens which have shown tendency to the greedy way of the nutrition. This paper is the contribution to the knowledge of a pikeperch nutrition in the river Neretva accumulations that is, beside the reproduction, the important character of population growth control of this greedy animal, and in the aim of the survival of the autochthonous ichthyopopulations in the river Neretva system.
An analysis of the contents of gastric-intestine system of a brown trout (Salmo trutta morfo fario) was carried out on 103 individuals in order to describe the feeding behaviour. The capture were ...made in the Una River (Bihac, Bosnia-Herzegovina), using generating sets and sacks. The dissection of specimens, the extraction of gastric-intestine contents and the fixation in 4% formaldehyde was carried out in loco. Further treatments and the microscope examination were carried out at the laboratory of Ichthyology and Fishing Center of the Faculty of Science, University of Sarajevo. The results obtained are very similar with the literature data. The brown trout dominantly fed on benthonic macro-invertebrate. A large percentage of fish fed on larvae stages of the two-winged insects (45,45%) and caddisflies (42, 42%). A small number of individuals fed on bullhead (7,07%) and on algae (1.01%). A strong dependence was found between the prey-species and the composition in species of the benthos. According to these results it is possible to define a zoophagous behaviour. The specimens with empty stomach, but very good developed gastric-intestine system, were also registered (4.04%). The data are related to the time of capture (the reproduction season when the brown trout feed less). The condition factor was calculated and varies from 1.00 to 1.59. According the average weight 21.77 g and average length (133.37 cm) the estimated condition factor is 1.09.
Analize sadržaja probavnoga trakta smuđa provedene su na osnovi pregleda 27 jedinki iz akumulacija slijeva Neretve. Izlov ribe obavili su postavljanjem mreža članovi Centra za ihtiologiju ...Prirodoslovno–matematskog fakulteta Sveučilišta u Sarajevu od 17. srpnja do 24. rujna 2002. Disekcija i fiksacija probavnoga trakta u 4 %–tnom formaldehidu izvršena je na terenu, a pregled sadržaja probavnoga trakta u Laboratoriju Prirodoslovno–matematskog fakulteta Sveučilišta u Sarajevu. Pojava smuđa u slijevu Neretve rezultat je slučajnog unosa u Ramsko jezero u (Š k r i j e l j, 1995; Š k r i j e l j i Ma š o v i ć, 2001). Rezultati analize sadržaja probavnoga trakta smuđa upućuju na veoma raznovrstan način prehrane uvjetovan kapacitetom vodnog ekosustava i veličinom jedinki. Sklonost prehrani drugim ribama izražena je u jezerima gdje je veća kompeticija s drugim vrstama riba, a u akumulacijskim jezerima (Salakovac, Mostar) izražena je sklonost kanibalizmu. Kanibalizam je karakterističan za jedinke smuđa koje su dulje od 30 cm. Sve jedinke iz jezera Grabovica (4) čija je dužina manja od 30 cm hranile su se zoobentosom, a u želucu jedne jedinke registrirane su i alge. Zbog utvrđene velike grabljivosti (kod većih jedinki) ove ribe dovodi se u pitanje opstanak važnih autohtonih vrsta riba (Salmonidae i Cyprinidae), što nedvojbeno uzrokuje veće ekološke promjene u srednjem toku slijeva Neretve u negativnome smislu. Ovakvo stanje nameće obvezu poduzimanja mjera u kontroli gustoće populacije smuđa i introdukcije uopće. Uspoređujući prehranu spomenute vrste ribe s drugim vrstama riba u neretvanskim akumulacijama (K a ć a n s k i i sur., 1976; T r o ž i ć – B o r o v a c, 2002a), možemo zaključiti da nema nikakva konkurenta, jer se sve se ribe hrane avertebratima i bentosnim biljkama, a samo su rijetki primjerci jezerske pastrve Salmo trutta m. lacustris Linnaeus, 1758 skloni grabljivom načinu prehrane. Rad pridonosi upoznavanju prehrane smuđa u neretvanskim akumulacijama, koja, uz reprodukciju, označuje bitan karakter u pronalaženju načina kontrole rasta populacije ove grabljivice i na taj način omogućivanje opstanka autohtonih ihtipopulacija u slijevu Neretve.
Na osnovi izlova 103 jedinke potočne pastrve (Salmo trutta m. fario Linnaeus, 1758) na 15 lokaliteta u slijevu rijeke Une u općini Bihać provedena je analiza želučano–crijevnog trakta u svrhu ...upoznavanja njezine prehrane. Izlov ribe obavljen je električnim agregatom i ručnim sakom. Disekcija potočne pastrve, izdvajanje digestivnoga trakta i pregled sastava ovog dijela probavnog sustava izvedeni su u laboratoriju Centra za ihtiologiju i ribarstvo Prirodno–matematskog fakulteta Univerziteta u Sarajevu. Dobiveni rezultati analize prehrane potočne pastrve donekle se poklapaju s podacima iz literature (Mc C o rma c , 1962; E l l i o t , 1967; Š e n k i A g a n o v i ć , 1968; T u š a , 1968; K a ć a n s k I i K o s o r i ć , 1970; P o p o v s k a — S t a n k o v i ć i G e o r g i e v , 1973; K a - ć a n s k i i sur., 1988). Dominantno su se jedinke potočne pastrve u istraživanim lokalitetima hranile makroinvertebratima bentosa (dna). Najveći postotak riba u svojoj prehrani upotrebljava preimaginalne stadije dvokrilnih insekata (45,45 %) i tulara (42,42 %). Utvrđen je mali broj riba koje su se hranile pešom (7,07%). Utvrđena je također velika ovisnost prehrane potočne pastrve o kvalitativno–kvantitativnom sastavu bentosa (T r o ž i ć – B o r o v a c , 2001). Vrlo mali broj riba hranio se algama (1,01 %). Prema ovim rezultatima može se uvjetno govoriti o zoofagu. Registrirane su i jedinke s praznim želucem, ali dobro razvijenim digestivnim traktom (4,04 %). Ovaj podatak u vezi je sa sezonom izlova, kada je potočna pastrva u rijeci Uni bila pred mrijestom pa se manje hranila. Za sve jedinke potočne pastrve izračunan je faktor kondicije (CF) koji se kreće od 1,00 do 1,59. Prema prosječnoj masi od 21,77 g i prosječnoj duljini od 133,37 cm taj faktor za analizirane ribe iz slijeva Une iznosi 1,09.

Conference Proceeding
The results of this study can be summarized in a few conclusions: 1) 75 species and subspecies have been found in the investigated catchments. Analyzing the data obtained by specifying materials for ...watershed Plecoptera, 51 species and one subspecies are related to the Bosna River Basin, at the confluence of the Drina (Maglić mountain resort, and Volujak Zelengora) 42 species and one subspecies, the upper basin of the river Drina 52 species and one subspecies , at the confluence of the Vrbas River, 33 species and one subspecies, the Neretva River basin belongs to 28 species and one subspecies, the basin Lasva 5 species and one type of basin drainage area. It can be concluded that in Bosnia and Herzegovina, there is a very wide degree of biological species diversity of Plecoptera order, which incorporates Bosnia and Herzegovina into the richer areas in Europe. 2) So far in the villages of Bosnia and Herzegovina 13 Plecoptera species and subspecies have been recorded that are endemic to the Balkans. Leuctra aptera is designated as endemic to the Dinaric Alps, but as Leuctra signifer jahorinensis is considered as an endemo of Bosnia and Herzegovina. Nine species and two subspecies Brachyptera beale, Brachyptera helenica, Brachyptera graeca, Brachyptera tristis, Leuctra hippopoides, Leuctra olympia, Leuctra procera, Isoperla albanians, Isoperla triparitia obliqa, Siphonoperla neglecta graeca and Chloroperla russevi, according to today understanding of their distribution only inhabited the Balkan Peninsula, and are now considered endemic to this area. It is important to emphasize the site of Isoperla intermis species, endemic to the Dinarides, which can be treated as a characteristic species for sources in the Bosnian-Herzegovinian holokarsta, where in some places reaches a high density population. Perla pallida has also been recorded known in the Caucasus, the Carpathians and Asia Minor. Glogovka the first and so far the only site of its kind in Bosnia and Herzegovina has been recorded, too. Type Taenopteryx kultreiberi in Bosnia and Herzegovina has been recorded so far only in the Lasva basin. 3) It is necessary to re-collect Plecoptera in the territory of Bosnia and Herzegovina, to make the determination, and then form a modern database of images, with emphasis on diagnostic characteristics of the studied taxa. Various aspects of human activity, such as for example deforestation, and various pollution greatly endanger the natural habitat types of the order Plecoptera. As a result of these and similar phenomena in some localities there is impoverishment of the population or even disappearance of Plecoptera including endemic species. Thus keeping the natural habitat is the most important measures to protect gene pool of these insects.
Austropotamobius torrentium (Schrank, 1803) lives in two watercourses, namely Subotica (Sana) and Toplik (Tilava). The influence of the ecological conditions of these rivers on individuals of this ...species is analyzed based on 22 morphometric parameters. The assessment of abiotic conditions was done through the measurement of physical and chemical water parameters and the analysis of the composition of phytobenthos and macrozoobenthos. Sampling was carried out in June, September, and October 2021. Water quality at the investigated localities (on the basis of abiotic and biotic parameters) is oligo to betamesosaprobic. A total of 37 crayfish were analyzed (20 from Subotica and 17 from Toplik). Female crayfish have shown significant differences in the head width (HEW) and abdominal thickness (ABH). Males differed significantly in a number of parameters, including the weight (W), head shape (HEL and HEW), rostrum length (ROL), carapace width (CPW), and abdominal shape (ABH and ABL). Higher values of the indicated parameters have been found in the males from the Subotica River. The obtained results are influenced by different ecological conditions of their habitats. The Subotica River is a larger watercourse in the lowland belt with a large number of microhabitats, and the Toplik is a small river in the mountain belt, with uniform sediment and a small number of ecological niches of the analyzed species. The general ecological conditions in the water of both watercourses are also affected by aquaculture facilities, where wastewater has a direct influence on the distribution of Austropotamobius torrentium individuals in the watercourses of the Subotica and Toplik Rivers. For more detailed and complete data, it is necessary to analyze a larger number of individuals in both populations, and to include additional morphometric-meristic parameters and molecular-genetic analyses.
This paper is a result of the research of the river Neretva benthos at sites Zitomislici and Visici (downstream of Mostar) from 2005. to 2010. The sampling was done once a year, and kick-sampling ...sampling was used for macrointervertebrates, while the samples for the analysis of the phytobenthos composition were scraped from the sediment with a scalpel or run-off from the sediment (standard EN 13946: 2003 Water quality – Guidance). Results of the analysis point to 62 algae taxa at site Zitomislici and 69 at site Visici. Macrointervertebrates benthos composition points on dominance of snails and sensible groups of larvae stages of the EPT insect groups. Saprobic values of both biological factors are relatively balanced and for the river Neretva, at site Zitomislici, point to oligo/betamesosaprobe level, while at site Visici they point to betamesosaprobe level of quality.

In this paper new data on diversity of wood ants in Bosnia and Herzegovina arepresented. First record of Formica truncorum Fabricius, 1804 from Duboštica isreported for Bosnia and ...Herzegovina. With this new finding total number of speciesfrom subgenus Formica s. str. known in Bosnia and Herzegovina is raised on five.Analysis of wood ants in central Bosnia indicated presence of Formica rufa Linnaeus,1761 on mountains Trebevic, Ozren, Perun while Formica polyctena Förster, 1850was collected only on Mt. Čemerska.Morphometrical and ethological intermediary indicate different Formica rufaphenotypes or hybrid Formica rufa x polyctena in investigated area. Polydomy wasobserved in Formica polyctena and F. rufa. On the mountain Perun 30 colonies ofFormica rufa in one kilometer transect were found, which represents the highestknown density in Bosnia-Herzegovina.
A study was carried out on the changes in content and abundance of local juvenile stonefly communities species at the sites Garež, Delijaš and Balbašići during autumn of 2009 and spring and summer of ...2010. A total of 1585 specimens were collected using a mash for zoobentos, out of which 541 were collected at the site Garež, 486 at the site Delijaš and 558 at the site Balbašići. The specimens were categorized into five families and 20 species. The most abundant species out of the total number at the site Garež was Leuctra nigra (73,94%), at the site Delijaš Perla marginata (19,96%), and at the site Balbašići Leuctra nigra (25,63%). The highest diversity indeces were at the site Delijaš, and the highest eveness was at site Balbašići. Key words: Crna Rijeka River, communities of juvenile stoneflies, Plecoptera
