Silver Fern Farms Manawatu River macroinvertebrate caging study

In March 2010, Aquanet conducted a caging study upstream and downstream of the discharge of treated effluent from the Silver Fern Farms Shannon fellmongery to the Manawatu River. The setup involved out-of-river containers, continuously fed with pumped river water, with smaller enclosures containing Potamopyrgus snail and Paratya curvirostris freshwater shrimp.
