The crayfish were caught by hand made baited traps from October 9nd 2018. until May 31th 2019. A total of 58 crayfish were caught, of which 38 males and 20 females. The eight morphometric characteristics: body weight (W), body length (TBL), claw length (CLL), cephalothorax length (CFL), carapace width (CPW), abdomen length (ABL), rostrum length (ROL) and rostrum width (ROW) were measured, both in males and females. Also, the body condition was determined for all specimens. The results of morphometric characteristics partially matched into the already known range of variations. These data represent first ones for the observed area. The t-test showed that there were significant differences between the sexes in W, TBL, CLL, CFL and CPW which are explained by the emphasized sex dimorphism of the noble crayfish.

The Dubska Pramenka is one of the biggest strains within the Pramenka breed. The wither heights of ewes and rams were 73.37 cm and 79.92 cm respectively, whereas the body lengths were 74.66 cm (ewes) and 80.42 cm (rams), and the rump heights were 73.72 cm (female) and 80.16 cm (male). Based on the data presented, it is evident that the Dubska Pramenka sheep has almost a square body shape with the rump height slightly greater than the wither height. The chest depth and shoulder width of ewes were 34.50 cm and 22.72 cm respectively, whereas those of males were 36.17 cm and 23.75 cm. In both sheep genders, the hip width (ewes 21.92 cm, rams 22.91 cm) was lower than the shoulder width. The chest and shin perimeters of females were 98.72 cm and 9.31 cm respectively, whe...

The paper presents the level of self-sufficiency and import dependence of fish for the period 2014-2020. The source of data was the data of the B&H Agency for Statistics and Indirect Taxation Authority of B&H. The following methods were applied: descriptive statistics, trend data and balance sheet method. On average, 3.161 tons of trout were produced in B&H per year, 82% of total fish production. Carp were produced 510 tons per year. Other freshwater fish are becoming less and less attractive for production. B&H's fish self-sufficiency is low (54%) and the average rate of import dependence is about 76%. The consumption of fish per capita is 2 kilograms. It is necessary to improve the education of the population throughout B&H about the importance of fish nutrition and the health aspects of its consumption.

An analytical calculation of total costs was used to compare the economic results of trout farming. The aim is to compare the achieved production and economic results of Rainbow trout farming in cage farms in Serbia and Bosnia and Herzegovina, and to analyze the influencing factors. The analysis showed minor differences in the natural conditions, production results, and economic results. Both analyzed farms are characterized by strong fluctuations of water temperature during the year. Such natural conditions affect negatively both the production and the economic results of farming. The analysis showed that the production is economically viable on both farms if the value of production is calculated together with subsidies, ie premiums. Without subsidies, the fish farm in BiH is operating at a loss.

Iako je zemlja sa dugom tradicijom proizvodnje ribe, još uvijek proizvodnja i potrošnja su na vrlo niskoj razini. U ovom radu prikazana je proizvodnja ribe u B&H, proizvodnja (morske ribe i vodeni organizama, proizvodnja slatkovodne ribe, šarana i pastrve). Također u radu su obrađeni podaci o B&H uvozu i izvozu ribe, te je procjenjena potrošnja ribe u 2009. god., predstavljena je riblja bilanca. Prelazak na tržišno gospodarstvo u Bosanskohercegovačkoj poljoprivredi (uključujući i ribarsku-akvakulturnu proizvodnju) utjecalo je na pad proizvodnje, smanjenje zaposlenosti, tehnološka zaostalost, zaduženost, pogoršanje bilance trgovinske razmjene i nelikvidnost. Ulaskom B&H u članstvo WTO dodatno je povećana i onako jaka međunarodna konkurencija. Strateški prioriteti se nužno moraju odrediti, te da se redefiniraju prioriteti u svrhu reorganizacije i prenamjene postojećih...

Cilj ovog rada je sagledavanje trgovinske razmjene proizvodima ribarstva (CT 0301-0307) BiH, te najčešćih destinacija u pogledu izvoza i uvoza. Rezultati istraživanja pokazuju da vrijednosti uvoza nadmašuju vrijednosti izvoza čime BiH u okviru glave 3 harmonizovanog sistema carinske tarife bilježi deficit u spoljnotrgovinskoj razmjeni. Analizirajući strukturu navedene glave pojedine carinske tarife i pored toga imaju pozitivne bilanse, ali nedovoljne za pokrivanje ukupnog deficita u okviru ribe i ljuskari, mekušci i ostali vodeni beskičmenjacima. BiH izvozi proizvode ribarstva uglavnom regionalnim partnerima u Srbiju i Hrvatsku, dok je uvoz najvećim dijelom iz zemalja EU

Anketom je obuhvaćeno po 39 ispitanika u BL i PD te 30 ispitanika u BN. Cilj rada je bio analiza kupovnih navika potrošača ribe u tri najveća grada Republike Srpske. Polna struktura ispitanika različita je po gradovima, u BL najviše je anketiranih osoba ženskog pola (56,41%), u PD je više ispitanika muškog pola (51,28%), dok je u BN struktura ispitanika bila podjednaka (50:50%). Dominantan je srednjoškolski nivo obrazovanja ispitanika (BL 53,8%, PD 33,3% i BN 56,7%). U sva tri grada dominantno mjesto kupovine ribe je supermarket, dok se najmanje ribe kupuje od ribolovaca i na ribnjaku. Između gradova postoji razlika u danima najčešće kupovine ribe, što je potvrđeno i 2 testom (p<0,05). U BL se najčešće kupuje riba utorkom, u PD srijedom i petkom, a u BN subotom. Statist...

Parametri eritrocitne i leukocitne loze predstavljaju veoma značajne pokazatelje stanja organizma riba i njihove vrijednosti su specifične za svaku vrstu. Osnovne karakteristike normalne krvne slike zdravih jedinki svake vrste moraju biti dostupne, prije njihovog korištenja u procjeni zdravstvenog stanja riba. Svaka vrsta ima krakterističan broj i veličinu eritrocita, koncentraciju hemoglobina, i hematološke indekse. Pored toga, postoje fiziološke varijacije svih parametara koje su pod uticajem pola, reprodukcije ili se pojavljuju tokom različitih faza životnog ciklusa vrste. Dnevne i sezonske oscilacije su takđe veoma dobro izražene. Sve vrijednosti hematoloških parametara kao i njihove varijacije su specifične za vrstu i/ili rasu i varijetet. Iz tog razloga smo u ovom radu ispitali dužičastu pastrmku porijeklom iz pet ra...

Paralelno sa ovom analizom urađena je i analiza makrozoobentosa kojim su se ribe hranile. Izlovljavanje riba je obavljeno sportskoribolovnom tehnikom, pri čemu je ulovljeno i analizirano ukupno 66 jednki, 33 iz izvora reke Plive i 33 iz reke Vrbanje. Morfometrijska analiza je obuhvatala određivanje: totalne dužine, standardne dužine i mase potočnih pastrmki, kao i dužine i mase digestivnog sistema istih, a ovi paramtri su poslužili za izračunavanje Fultonovog koeficijenta uhranjenosti. Istraživanje je pokazalo promenu u vrednostima parametara potočnih pastrmki sa ova dva lokalitela, kao i promenu istih između polova. Analiza makrozoobentosa koji je služio kao hrana ribama, pokazala je da je najveći udeo u plenu bio iz reda: Ephemeroptera, Trichoptera i Diptera. Larve Diptera iz familije Simuliidae su najčešći plen riba iz rijeke Plive, dok su se ribe iz rijeke Vrbanje najradije hranile larvama Chironomidae. Nije pronadjen ni jedan prazan digestivni sistem potočnih pastrmki u istraživanju. Svi rezultati su statistički obradjeni u programu ANOVA, a razlike izmedju grupa odredjene su stepenom značajnosti pomoću Fiserovog i t-testa.

Total of 205 ewes and rams was measured in order to determine similarities and differences between them. The eight, most important, morphometric trait were determined: wither height, rump height, body length, shoulder width, chest depth, hip width, chest perimeter and shin perimeter. Ewes of Dub Pramenka in relation to Privor and Kupres strains had pronounced morphometric measures, and established differences were statistically significant and highly significant. Statistically significant differences in all measures was observed between rams, expect for hip width. The obtained results show a significant difference in morphometric measures of three autochthonous Pramenka strains from Central Bosnia.

In aquaculture, various agents are used, such as copper, for the purpose of preventive action and prevention of the appearance of pathogens (ectoparasites, etc.). The aim of this study was to determine the effects of substrate-fixed copper microparticles on the growth and survival of juvenile rainbow trout (Oncorhynchus mykiss) up to the age of 5 months. The experiment was conducted in the Laboratory for Aquaculture of the Faculty of Agriculture, University of Banja Luka, for 142 days in flow aquariums with a 65 l/aquarium volume. The experiment was set up in two groups (150 units/group) with three replicates (50 units/replicate), a control group without copper microparticles (K) and a group with copper microparticles (Cu). The initial weight and total body length (mean ? SD) of rainbow trout in group K were 0.199 ? 0.008 g and 2.876 ? 0.036 cm, and in group Cu 0.197 ? 0.009 g and 2.893 ? 0....

Cilj ovog rada je sagledavanje trgovinske razmjene proizvodima ribarstva (CT 0301-0307) BiH, te najčešćih destinacija u pogledu izvoza i uvoza. Rezultati istraživanja pokazuju da vrijednosti uvoza nadmašuju vrijednosti izvoza čime BiH u okviru glave 3 harmonizovanog sistema carinske tarife bilježi deficit u spoljnotrgovinskoj razmjeni. Analizirajući strukturu navedene glave pojedine carinske tarife i pored toga imaju pozitivne bilanse, ali nedovoljne za pokrivanje ukupnog deficita u okviru ribe i ljuskari, mekušci i ostali vodeni beskičmenjacima. BiH izvozi proizvode ribarstva uglavnom regionalnim partnerima u Srbiju i Hrvatsku, dok je uvoz najvećim dijelom iz zemalja EU

Anketom je obuhvaćeno po 39 ispitanika u BL i PD te 30 ispitanika u BN. Cilj rada je bio analiza kupovnih navika potrošača ribe u tri najveća grada Republike Srpske. Polna struktura ispitanika različita je po gradovima, u BL najviše je anketiranih osoba ženskog pola (56,41%), u PD je više ispitanika muškog pola (51,28%), dok je u BN struktura ispitanika bila podjednaka (50:50%). Dominantan je srednjoškolski nivo obrazovanja ispitanika (BL 53,8%, PD 33,3% i BN 56,7%). U sva tri grada dominantno mjesto kupovine ribe je supermarket, dok se najmanje ribe kupuje od ribolovaca i na ribnjaku. Između gradova postoji razlika u danima najčešće kupovine ribe, što je potvrđeno i 2 testom (p<0,05). U BL se najčešće kupuje riba utorkom, u PD srijedom i petkom, a u BN subotom. Statist...

Parametri eritrocitne i leukocitne loze predstavljaju veoma značajne pokazatelje stanja organizma riba i njihove vrijednosti su specifične za svaku vrstu. Osnovne karakteristike normalne krvne slike zdravih jedinki svake vrste moraju biti dostupne, prije njihovog korištenja u procjeni zdravstvenog stanja riba. Svaka vrsta ima krakterističan broj i veličinu eritrocita, koncentraciju hemoglobina, i hematološke indekse. Pored toga, postoje fiziološke varijacije svih parametara koje su pod uticajem pola, reprodukcije ili se pojavljuju tokom različitih faza životnog ciklusa vrste. Dnevne i sezonske oscilacije su takđe veoma dobro izražene. Sve vrijednosti hematoloških parametara kao i njihove varijacije su specifične za vrstu i/ili rasu i varijetet. Iz tog razloga smo u ovom radu ispitali dužičastu pastrmku porijeklom iz pet ra...

Paralelno sa ovom analizom urađena je i analiza makrozoobentosa kojim su se ribe hranile. Izlovljavanje riba je obavljeno sportskoribolovnom tehnikom, pri čemu je ulovljeno i analizirano ukupno 66 jednki, 33 iz izvora reke Plive i 33 iz reke Vrbanje. Morfometrijska analiza je obuhvatala određivanje: totalne dužine, standardne dužine i mase potočnih pastrmki, kao i dužine i mase digestivnog sistema istih, a ovi paramtri su poslužili za izračunavanje Fultonovog koeficijenta uhranjenosti. Istraživanje je pokazalo promenu u vrednostima parametara potočnih pastrmki sa ova dva lokalitela, kao i promenu istih između polova. Analiza makrozoobentosa koji je služio kao hrana ribama, pokazala je da je najveći udeo u plenu bio iz reda: Ephemeroptera, Trichoptera i Diptera. Larve Diptera iz familije Simuliidae su najčešći plen riba iz rijeke Plive, dok su se ribe iz rijeke Vrbanje najradije hranile larvama Chironomidae. Nije pronadjen ni jedan prazan digestivni sistem potočnih pastrmki u istraživanju. Svi rezultati su statistički obradjeni u programu ANOVA, a razlike izmedju grupa odredjene su stepenom značajnosti pomoću Fiserovog i t-testa.

Total of 205 ewes and rams was measured in order to determine similarities and differences between them. The eight, most important, morphometric trait were determined: wither height, rump height, body length, shoulder width, chest depth, hip width, chest perimeter and shin perimeter. Ewes of Dub Pramenka in relation to Privor and Kupres strains had pronounced morphometric measures, and established differences were statistically significant and highly significant. Statistically significant differences in all measures was observed between rams, expect for hip width. The obtained results show a significant difference in morphometric measures of three autochthonous Pramenka strains from Central Bosnia.

In aquaculture, various agents are used, such as copper, for the purpose of preventive action and prevention of the appearance of pathogens (ectoparasites, etc.). The aim of this study was to determine the effects of substrate-fixed copper microparticles on the growth and survival of juvenile rainbow trout (Oncorhynchus mykiss) up to the age of 5 months. The experiment was conducted in the Laboratory for Aquaculture of the Faculty of Agriculture, University of Banja Luka, for 142 days in flow aquariums with a 65 l/aquarium volume. The experiment was set up in two groups (150 units/group) with three replicates (50 units/replicate), a control group without copper microparticles (K) and a group with copper microparticles (Cu). The initial weight and total body length (mean ? SD) of rainbow trout in group K were 0.199 ? 0.008 g and 2.876 ? 0.036 cm, and in group Cu 0.197 ? 0.009 g and 2.893 ? 0....
