  • Minnesota, USA: A challenging climate for fish

    Icy winters and hot summers resulted in fish kills at this Minnesota farm raising walleyes, muskellunge, black crappies and northern pike. In winter, ice and snow on the pond’s surface caused dissolved oxygen levels to drop below 5 ppm, stressing the fish. Summer heat decreased the pond’s capacity to hold dissolved oxygen and caused excessive algae growth. The farm tried fountain aerators to ...

  • Modifications of macrobenthos assemblages on land–based fish farm phytotreatment basins in the Orbetello lagoon

    In the Orbetello lagoon basin there are some intensive land–based fish–farming facilities which contribute to cause a significant cyclic development of the opportunistic chorophycea Ulva laetevirens, and consequent serious decay events in spring and summer. To minimise the nutrients' impact, fish farming was supplied with phytotreatment system. The purpose of this study was to ...

  • Jamaica: Tilapia pioneer expands

    Since 1983, this red tilapia farm has been using AIRE-O2® aerators in its grow-out ponds, which produce millions of pounds of fish per year for the Jamaican market and for export. In a1990 interview, a manager at the farm said, 'We have AIRE-O2® aerators here that have been running continuously for eight years. For maintenance people, its like a dream come true.' He added, ' these AIRE-O2® ...

  • Use of sea water and hydraulic conditions. Potential cause of Mortality by Metals and Hydrogen Sulfide in Recirculation Fisheries

    The traditional conception in Chile of the toxic effect of metals on cultured fish tends to weigh heavily on incoming freshwater in open flow fish farms as the major responsible for mortality in early stages of development in salmon species. This approach is mainly based on two conditions that refer to freshwater quality in Chile, and to the dilutive effect of recirculation fish stocks when a ...
