Sakaryabaşi Alabal ı k Çiftliği Giri ş ve Çı kış Suyunun Kalite Özellikleri

Bu araşt ı rma, Bat ı Göleti'nin giriş suyu alabal ı k üretimi için su kalite kriterleri aç ı s ı ndan uygun olup olmad ı 'g ı n ı belirlemek ve alabal ı k yetiştiricili ği ç ı kış suyunun Sakarya nehri üzerindeki etkisini değerlendirmek için yap ı lm ışt ı r. Bu amaçla, bir alabal ı k çiftliğinin kara-isletmesi giri ş ve çik ış sular ı nda 12 ay süreyle, baz ı su kalite parametreleri tespit edilmi ştir. Sonuçlar, literatür verileriyle karşilaşt ı rı lmişt ı r. Toplam amonyak azotu 0.487 ± 0,15 mg/L ve toplam fosfor de ğerleri 461.1 ± 81.34 gg/L d ışı nda giriş suyunda ölçülen baz ı fiziksel ve kimyasal özellikler su s ı cakl ığı , çözünmüş oksijen, pH, kondüktivite, organik madde, toplam sertlik, bikarbonat alkalinitesi alabal ı k üretimi için kabul edilebilir standart s ı n ı rlar içerisinde bulunmuştur. Çı kış suyunda ise, toplam amonyak azotu, nitrit-azotu, nitrat-azotu, çözünmü ş ortofosfat değerleri standart ç ı k ış suyu s ı n ı r değerleri içerisindedir. Ancak, çal ışma periyodu boyunca ç ı kış suyu toplam fosfor konsantrasyonu ortalama 518.5 ± 90.1 ji.g/L olarak tespit edilmi ş, en yüksek olarak May ı s ay ı nda 994.64 ± 4.44 pg/L bulunmu ştur. Giriş suyunda da belirlenen yüksek toplam fosfor de ğeri, giriş suyunun su kalitesinin kontrol ve yönetiminin üzerinde durulmas ı gereken esas konu oldu ğunu ortaya koymuştur.

Water Quality Parameters in Inflow and Outflow of Sakaryaba şı Trout Farm

This research was conducted to determine the suitability of the Bat ı Pond inflow in terms of water quality standards for trout production and to evaluate its impact on the River Sakarya. For this purpose, several water quality parameters were measured in inflow and outflow of a land-based trout farm over a 12-month period. The results were compared with the literature data. With the exception of total ammonia nitrogen 0.487±0.15 mg/L and total phosphorus 461 .1±81.34 1.ıg/L. values, the measured some physical and chemical parameters water temperature, dissolved oxygen, pH, conductivity, organic matter, total hardness, bicarbonate alkalinity of inflow were within the acceptable standard limits for trout production. In the outflow, total ammonia nitrogen, nitrite-nitrogen, nitrate-nitrogen, dissolved reactive phosphorus were within the standard effluent limits. The mean of total phosphorus concentration at the outflow was during the study period averaged 518.5±90.1 ug/L and the highest total phosphorus concentration was found in May 994.64±4.44 1. ıg/L . High value of total phosphorus was also observed in the inflow, suggesting that water quality control and management of inflow becomes an essential concern.
