During August and September 2018 we collected the macroinvertebrate fauna in the Leqinat Lake, Kosovo. The Leqinat lake (great lake) is a mountain lake found in the National Park “Bjeshkët e Nemuna” in western Kosovo, shared between Kosovo and Montenegro. Macrozoobenthos specimens were collected with D-frame net of 30×20 cm (600 cm2) diameter. Samples were taken from all available habitats represented with more than 5% of total habitat area on the sampling stretch (multi-habitat sampling procedure). Sampling in riffle section of the lake was done by identifying the riffle segments, disturbing the substratum with the feet while holding the net downstream with the mouth facing upstream. The macrozoobenthos structure during this investigation includes: 2 classes (Bivalvia and Gastropoda), 2 subclasses (Hirudinea and Oligochaeta), 6 orders (Ephemeroptera, Plecoptera, Trichoptera, Diptera, Coleoptera and Odonata), 15 families, 6 genera and 86 specimens. The larger numer of families and individuals belongs to the Odonata order (4 families and 47 specimens) followed by Tirchoptera (2 families and 10 specimens), Plecoptera (2 families and 6 specimens), Bivalvia (2 families with 5 specimens) Diptera (1 family with 12 specimens), Ephemeroptera and Hirudinea (1 family with 3 specimens) and Oligochaeta (1 family with only 1 specimens). This investigation is a contribution in knowing the macroinvertebrate fauna and their ecological patterns in alpine lakes in Kosovo.
The present study aimed to study the diversity and density of the benthic fauna along the Inaouene wadi in relation to the variation of physicochemical parameters and heavy metals at six sampling stations representing the major part of the studied watercourses. The samples were taken during March and April 2019. The fauna recorded in this work consists of 2029 individuals corresponding to 39 families and 10 orders. The benthic population size showed that Oligochaetes, Diptera, Heteroptera, Trichoptera and Ephemeroptera are dominant. The diversity indices of Shannon and Weaver, and Piélou show that station S6 favors a better development of macroinvertebrates. This is confirmed by the values of physicochemical parameters and studied noble metals lord which shows that the stations S1, S3, S4 have poor water quality, compared to S6 and S5, the waters of which are of good quality, reflecting the self-purifying action of the watercourses between Wadi Amlil and Idriss I dam.
In this paper, the results of the analyses of selected chemical water quality parameters and taxonomic composition of macroinvcrtebrates of the Liwiec River and its chosen tributaries (central-eastern Poland) arc presented. Chemical and biological water quality assessment was performed, and four biotic indices were tested: Belgian BB1, French IBGN, British BMWP/OQR, and biotic index BMWP-PL developed for Polish rivers. Correlations between the values of the latter and chemical water parameters show that BMWP-PL is a useful tool for the assessment of water quality of lowland rivers in Poland (similar to the Liwiec).

W pracy przedstawiono wyniki badań wybranych parametrów chemicznych wody i składu taksonomicznego makrobczkręgowców rzeki Liwiec i jej wybranych dopływów (środkowo-wschodnia Polska). Dokonano chemicznej i biologicznej klasyfikacji badanych wód. Przetestowano cztery indeksy biotyczne: belgijski BB1, francuski 1BGN, opracowany w Wielkiej Brytanii BMWP/OQR oraz opracowany na potrzeby biologicznej klasyfikacji rzek w Polsce indeks biotyczny BMWP-PL. Korelacja pomiędzy wartościami indeksu BMWP-PL a parametrami chemicznymi wody wskazuje na przydatność indeksu BMWP-PL do oceny jakości nizinnych rzek (typu Liwiec) w Polsce.
Considering the fact that water quality monitoring programs in Poland are mostly based on physicochemical variables and saprobic systems, it is important to evaluate also the possibility of applying biotic index methods for water quality assessment. The investigation was carried out at the Ścinawa Niemodlińska river (Opole Voivodeship). Benthic macroinvertebrates from seven sampling sites were sampled twice in 1999. Belgian Biotic Index values were calculated on the basis of the results of qualitative and quantitative analyses of the macroinvertebrate community, as the example of the biotic index application. BBI values indicated a low, but different in particular sites, pollution level of the studied ecosystem.

Biorąc pod uwagę fakt, iż programy monitoringu jakości wód w Polsce oparte są w większości na parametrach fizyczno-chemicznych i systemie saprobów, istotnym jest oszacowanie możliwości zastosowania metody indeksu biotycznego w ocenie jakości wód. Badania prowadzono na rzece Ścinawa Niemodlińska (woj. opolskie). Próbki makrobezkręgowców bentosu pobierano z siedmiu stanowisk dwukrotnie w roku 1999: Na podstawie wyników analizy jakościowej i ilościowej zespołu makrobezkręgowców obliczano Belgijski Indeks Biotyczny, jako przykład zastosowania indeksu biotycznego. Wartości BBI wskazywały na niski, lecz zróżnicowany pomiędzy poszczególnymi stanowiskami, poziom zanieczyszczenia badanego akwenu.
