摘要

The effect of phosphorus from a newly constructed public fish hatchery (known as the Oneida Fish Culture Station or OFCS) on Cladophora abundance in nearshore areas of Oneida Lake, New York, USA, was evaluated. Total phosphorus (TP) and soluble reactive phosphorus (SRP) were monitored above and below the OFCS (on Scriba Creek) and at a reference site (Murray Creek) and Cladophora abundance was indexed at nearshore areas surrounding both streams from late April to early October 1993-1995. The OFCS has a unique particulate disposal system that involves the settling and subsurface leaching of supernatant to minimize phosphorus discharges. The amount of phosphorus entering Scriba Creek annually from the OFCS was estimated at <38 kg. Although concentrations of TP and SRP tended to be higher downstream of the OFCS, these higher levels were associated neither with periods of peak fish food consumption nor peak fish biomass. Although mean annual concentrations of TP and SRP were higher in Scriba Creek than in Murray Creek, abundance of Cladophora was higher at nearshore areas surrounding Murray Creek. The results indicate that phosphorus losses from the OFCS were low, that OFCS phosphorus contributions did not lead to nuisance levels of Cladophora, andthat coupling sound waste management with fish hatchery design was instrumental in minimizing the environmental impact to nearshore areas of Oneida Lake.
