The transportation of pollutants from impervious surfaces during runoff events to receiving water bodies is a serious environmental problem. Summer runoff is also heated by impervious surfaces, causing thermal enrichment in receiving water body systems and degradation of coldwater aquatic ecosystems. End-of-pipe stormwater management facilities that are open to the environment can result in fur...

Serbian aquaculture is practiced in warmwater (carp) farms, coldwater (trout) cage systems, recirculating systems (RAS) and fish tanks. The total area under carp farms (ponds) registered by the Statistical Office of Republic Serbia (SORS) last fourteen years has varied between 6,192 8,940 ha, while trout was 33,255 m2 81,411 m2. Total production over 5,070 tons, recorded 2017 8,195 tons market ...

Serum and mucosal antibody responses of juvenile rainbow trout, Oncorhynchus mykiss, were characterized by enzyme-linked immunosorbent assay (ELISA) following immunization with various preparations of formalin-killed Flavobacterium psychrophilum cells. The protective nature of these preparations was then determined by immunizing rainbow trout fry and challenging with the bacterium. Juvenile rai...

In general, water cannot be economically pumped through raceways; it must flow through them by gravity. The need for large volumes of good quality water is the principal reason raceways have been limited to sites with large springs. Most raceway culture in the U.S. is with coldwater species such as trout and is based around locations with high volume, cold springs, or creeks. A few raceway syst...

We examined the effects of a commonly used preservation technique on mercury concentration in fish tissue. After fixing fish muscle tissue in formalin followed by preservation in isopropanol, we found that mercury concentration in fish muscle tissue increased by 18%, reaching an asymptote after 40 days. We used formalin-isopropanol-preserved longear sunfish (Lepomis megalotis) from the Sam Nobl...

Headwater streams support vital aquatic habitat yet are vulnerable to changing climate due their high elevation and small size. Coldwater fish especially sensitive the altered streamflow water temperature regimes during summer low flow periods. Though previous studies have provided insights on how changes in alterations stream discharge may affect availability for various native cutthroat trout...
