Regarded as a protected species on the IUCN list of endangered species, and classified as data deficient species, the stone crayfish (Austropotamobius torrentium) is one of the five European species from the Astacidae family that lives in freshwater ecosystems across Bosnia and Herzegovina. The aim of this study was to investigate the variability of selected morphometric characteristics of male and female crayfish of the A. torrentium species from the upper reaches of the Mlinska River. The crayfish were sampled in June 2021 when 62 individuals (22 males and 40 females) were caught. They were analyzed fresh in the field and in the laboratory. The treatment included the measurement of 12 morphometric features: total body length (TBL), weight (W), claw length (CLL), claw width (CLW), carapace length (CPL), carapace width (CPW), rostrum length (ROL), rostrum width (ROW), abdominal length and width (ABL, ABW) and telson length and width (TEL, TEW). The mean body length ± SD was 79.05 ± 7.35 in males and 60.54 ± 10.03 mm in females. The mean recorded body weight ± SD was 17.51 ± 8.3 g in males and 7.02 ± 4.41 g in females. Using the linear regression method, a positive correlation was found between body length and weight (♂ R2=0.7644; ♀ R2=0.8222), body weight and claws length (♂ R2=0.876; ♀ R2=0.9661), as well as carapace width and body length (♂ R2=0.7216; ♀ R2=0.8411). Using the T-test, a statistically significant difference of the analyzed morphometric parameters was found between the sexes, which is explained by the pronounced sexual dimorphism of stone crayfish. The calculated values for Condition factor and the Crayfish constant indicate that the males are of better fitness, which is in line with the results of previous research in Europe. Data presented in this paper can serve as a basis for further research of A. torrentium in this area.
In these times of aggressive and enormous anthropogenic alterations of freshwater aquatic habitats throughout the Western Balkans, including drying out, pollution or the introduction of invasive species, the value of small water bodies
Kratak sadržajIhtioparazitološkim istraživanjem 177 jedinki crnog somića (Ameiurus melas) iz hidroakumulacije Modrac (Bosna i Hercegovina) utvrđeno je prisustvo pet vrsta ektoparazita. Paraziti pripadnici Subregnuma Protozoa nađeni su kod 107 jedinki ili 60,45% od ukupnog broja analiziranih jedinki crnog somića. Rezultati sprovedenog istraživanja pokazali su da je najveći broj infestiranih jedinki crnog somića tokom ljeta (48 jedinki -44,85%), dok je zastupljenost parazita u jesen najmanja (18 jedinki -16,82%). Najvišu prevalencu infestacije ostvaruje Trichodina sp., dok je Ceratium spp. zastupljen u najmanjem procentu. U odnosu na ukupni ihtiouzorak sve determinirane vrste ektoparazita pokazuju slab intenzitet infestacije.Ključne riječi: Protozoa, paraziti, crni somić, hidroakumulacija Modrac, Bosna i Hercegovina.Isat Skenderović, Avdul Adrović, Edina Hajdarević, Elvira Hadžiahmetović Jurida, Adnan Jažić, Stjepan Krčmar Original paper FREQUENCY OF EMERGENCE OF PARASITIC PROTOZOA ON AMEIURUS MELAS IN LAKE MODRAC (BOSNIA AND HERZEGOVINA) AbstractThe ichtyological study of 177 specimens of the Ameiurus melas from Lake Modrac (Bosnia and Herzegovina) proved the presence of ive types of ectoparasites.
The role of the renin-angiotensin aldosterone system in the genesis of hypertension between nonhunting dogs and hunting dogs of various breeds was comparatively studied in the city of Tuzla (Bosnia and Herzegovina). Sixty dogs were divided into four subgroups based on different age categories. Hypertension was recorded in 21 dogs or in 35% of examined dogs. Fourteen dogs had mild (23.3%), 5 dogs had moderate (8.3%), and 2 dogs had severe hypertension (3.3%). The most cases of hypertension (n = 9) were recorded in hunting dogs aged from 9 to 12 years. In subgroups of nonhunting and hunting dogs aged from 1 to 3 years, a high correlation was recorded between systolic and diastolic pressures (P < 0.0001). A certain degree of correlation was recorded between systolic pressure and renin (P = 0.037) and between heart rate and renin (P = 0.024). In subgroups of nonhunting and hunting dogs aged from 9 to 12 years, a high correlation was recorded between systolic and diastolic pressures (P = 0.006) and between diastolic pressure and heart rate (P = 0.002). A certain degree of correlation existed between systolic pressure and heart rate (P = 0.041), systolic pressure and aldosterone (P = 0.035), and heart rate and renin (P = 0.038). Increased values of renin were mostly recorded in dogs with hypertension. This research indicates the importance of routine blood pressure measurement during every examination, which can thus serve as a screening for undertaking further steps in processing the patient.
Danas je poznato da su u svijetu upravo bolesti kardiovaskularnog sistema vodećiuzrok mortaliteta. Jedan od kapitalnih parametara koji nam na jednostavan način i ukratkom vremenu daje mnogo vrijednih pokazatelja zdravlja pacijenata je mjerenjekrvnog pritiska. To je jedan od načina da se dobije objektivan uvid u zdravstvenostanje pacijenta i stanje njegovog kardiovaskularnog sistema. Općenito, hipertenzijase može defi nisati kao hronično povećanje sistolnog i dijastolnog krvnog pritiska, uznapomenu da je hipertenzija nerazdvojivo povezana sa funkcionalnim i strukturnimpromjenama u zidovima krvnih sudova. Fiziološke vrijednosti krvnog pritiska kod pasakreću se u rasponu od 118 do 149 mmHg, sistolni, i 66–88 mmHg, dijastolni. Uzimajućiu obzir dob, rasu i spol, ustanovljeni su kriterijumi, odnosno protokol, koji suprihvaćeni od Svjetskog udruženja veterinara (World Veterinary Association, WVA).Našim istraživanjem je obuhvaćeno i ispitano ukupno 60 pasa različitih pasminana prostoru općine Tuzla. Tretirani psi označeni su kao grupa A, a čine je nelovačkipsi različitih pasmina koji su podijeljeni u četiri podgrupe sa po 15 pasa, označenesa A1–A4, na bazi različite dobne kategorije.Tokom rutinske pretrage, kao parametri pomoću kojih je izvršena detekcija hipertenzije,uzeti su sistolni, dijastolni krvni pritisak, frekvencija pulsa te starosnadob psa, kao i procedura neophodna za mjerenje koncentracije renina i aldosterona.Kod svih grupa pasa, detektovani su blagi, srednji i teški tip hipertenzije. Kod ispitivanihpasa, blaga hipertenzija je zastupljena kod 14 pasa (23,3%), srednja kod 10(16,6%), i teška kod samo tri psa (5%). Kod 33 psa (55%) nije registrovan niti jedantip hipertenzije.Naša istraživanja su ukazala i na činjenicu koliko je bitno, prilikom svakoga pregledapacijenta, provesti rutinsko mjerenje krvnog pritiska koje nam služi kao screeningza poduzimanje sljedećeg koraka, bilo dijagnostičkog ili terapeutskog.
