Sakaryabaşı Batı Göletinin Ötrofikasyon Derecesinin Araştırılması

Bu çal ışmada Sakaryabaşı Bal ı k Üretim ve Araştı rma Istasyon ıfna su sağlayan Batı Göleti'nin dtrofikasyon derecesinin belirlenmesi amaçlanm ışt ı r. Golet suyunda başta fosfor fraksiyonlan toplam fosfor, toplam ortofosfat, toplam filtre edilebilir ortofosfat, partiküler inc ı rganik fosfor olmak üzere azot fraksiyonlan amonyak azotu, nitrit azotu, nitrat azotu , klorofil-a konsantrasyonu ile baz ı fiziko-kimyasal özellikler su s ı caklığı , çözünmü ş oksijen, pH, ışı k geçirgenliğ i, elektrik iletkenliği, toplarn sertlik, kalsiyum ve magnezyum sertli ğ i, organik madde, bikarbonat alkalinitesi dikkate al ı nm ıştı r. Toplam fosfor konsantrasyonu baz al ı nd ığı nda, goletin bask ı düzeyi aç ı s ı ndan hiperdtrofik oldu ğ u ve özellikle amonyak-azotu değerinin bütün deneme periyodu boyunca alabal ı k yetiştiricili ğ i yap ı lan sular için izin verilen değerden yüksek olduğ u saptanmıştı r. Elde edilen veriler doğ rultusunda gölet yönetimine ili şkin önerilerde de bulunulmuştur

A Research on the Eutrophication Level of the Sakaryaba ş: West Pond

In this study, determination of the eutrophication state of the pond which supply water to the Sakaryabaşı Fish Culture and Research Station was aimed. In pond water. primarily phosphorus fractions total phosphorus, total orthophosphate,. total filtrable orthophosphate, particular inorganic phosphorus , and also nitrogen fractions ammonia-nitrogen, nitrite-nitrogen, nitrate-nitrogen , chlorophyll-a concentration and some phsico-chemical characteristics water temperature, dissolved oxygen, pH, transparency, electrical conductivity, total hardness, calcium and magnesium hardness, organic matter, bicarbonate alkalinity were undertaken. Regarding the total phosphorus concentration, it was detected that trophic state of the pond was hypereutrophic, and especially the values of ammonianitrogen, are higher than the acceptable values for rainbow trout production. The management strategies ware recommended depending on the data obtained.
