Ichthyofauna of the lower part of Bliznec stream

Uzorci riba lovljeni su elektroagregatom na donjem toku potoka Blizneca u dva navrata tijekom studenoga 2008. godine. Ukupno je ulovljeno 50 riba. Zabilježene su četiri vrste i to Carassius gibelio, Gobio gobio, Perca fluviatilis i Squalius cephalus, od kojih je S. cephalus najbrojniji. Sve vrste, osim klena imaju negativan alometrijski rast s b vrijednostima nižima od 3. Iako klen ima pozitivnu alometriju, b vrijednost mnogo je niža od hrvatskog prosjeka. I ostale proučavane vrste imaju b vrijednost ispod hrvatskog prosjeka. Faktor kondicije je vrlo nizak i ispod je hrvatskog prosjeka kod klena i grgeča, u prosjeku kod krkuše, a lagano iznad prosjeka kod babuške. Potok Bliznec vrlo je siromašan biotop kako za grgeča tako i ostale proučavane vrste.The fish were sampled in the lower parts of the Bliznec stream using an electroaggregate on two separate occasions in November 2008. A total of 50 fish were sampled. The samples belonged to 4 distinct species: Carassius gibelio, Gobio gobio, Perca fluviatilis and Squalius cephalus. Chub was found to be the most abundant. All species apart from chub were found to exhibit negative allometric growth (b<3), yet all of them exibit a b value lower than the croatian average. CF was found to be very low and below croatian average for chub and perch, average for gudgeon, and slightly above average for prussian carp. The freshwater environment of Bliznec stream was found to be a species poor biotope

Water for all : Proceedings of the 7th international scientific and professional conference Water for all

The 7th International Scientific and Professional Conference Water for all is organized to honour the World Water Day by the Josip Juraj Strossmayer University of Osijek, European Hygienic Engineering & Design Group (EHEDG), Danube Parks, Croatian Food Agency, Croatian Water, Faculty of Food Technology Osijek, Faculty of Agriculture in Osijek, Faculty of Civil Engineering Osijek, Josip Juraj Strossmayer University of Osijek Department of Biology, Josip Juraj Strossmayer University of Osijek Department of Chemistry, Nature Park “Kopački rit”, Osijek- Baranja County, Public Health Institute of the Osijek- Baranja County and „Vodovod-Osijek“ -water supply company in Osijek. The topic of World Water Day 2017 was "Wastewater" emphasizing the importance and influence of wastewater treatments on global environment. The international scientific and professional conference Water for all is a gathering of scientists and experts in the field of water management, including chemists, biologists, civil and agriculture engineers, with a goal to remind people about the significance of fresh water and to promote an interdisciplinary approach and sustainability for fresh water resource management. The Conference has been held since 2011. About 300 scientists and engineers submitted 95 abstracts to the 7th International Scientific and Professional Conference Water for all, out of which 33 was presented orally and 62 as posters. 47 full papers were accepted by the Scientific Committee. 38 full papers became the part of the this Proceedings while 9 papers were accepted for publication in Croatian Journal of Food Science and Technology and Electronic Journal of the Faculty of Civil Engineering Osijek - e-GFOS
