Abstract (2. Language): 
The growing demand in fish meal leads to increase in its price. This increase results in the search of raw materials that can be an alternative to fish meal. It is highly important to produce fish silage out of wastes of processing industry and use it in fish feed industry as an alternative stuff to some of fish meal. This study aims to analyse the chemical and microbiological properties of fish silage produced out of wastes of processing industry. This study puts forward that protein content of the silage is lower than that of fish meal. However, its amino acids profile revealed that fish silage have high quality protein content. Following its storage, the fish silage lipid content reached to 32.71% with a level of 25% PUFA and having 9% omega 3 fatty acid and 3.7% omega 6 fatty acid rates. It was seen that there is no microbiologically problem, like an increase in the number of bacteria or another negative change in microbiological quality parameters, to use the produced silage immediately after its maturity or storage. This study brings forward that the fish silage produced out of wastes of processing industry can be used as an alternative substance to fish meal if its protein deficit is met by protein concentrators.

Abstract (Original Language): 
Balık ununa olan talebin her geçen gün artması balık unu fiyatlarında artışa sebep olmaktadır. Bu artış, balık ununa alternatif olabilecek hammaddelerin aranmasına neden olmaktadır. İşleme sanayi atıklarından silaj yapılması ve yem sanayinde balık ununun bir kısmı yerine alternatif hammadde olarak kullanılması oldukça önemlidir. İşleme sanayi atıklarından üretilen silajın kimyasal ve mikrobiyolojik özelliklerinin incelenmesi bu çalışmanın amacıdır. Yapılan çalışmada üretilen silajın protein değeri balık ununa göre düşük bulunmuştur. Ancak aminoasit dağılımına bakıldığında yüksek kalitede protein içerdiği tespit edilmiştir. İşleme atığı silajının depolama sonucunda ham yağ değeri %32,71, PUFA değeri %25, omega 3 yağ asidi miktarı %9 ve omega 6 yağ asidi miktarı %3,7 olarak belirlenmiştir. Üretilen silajın olgunlaşmasından hemen sonra veya depolamadan sonra kullanılmasında bakteri sayısında artma veya mikrobiyolojik kalite parametrelerinde olumsuz bir değişim olmadığı için mikrobiyolojik açıdan bir problem olmadığı görülmüştür. Bu çalışmada işleme sanayi atıklarından üretilen silajın protein açığının protein zenginleştiricilerle giderilmesi durumunda balık ununa alternatif bir hammadde olabileceği ortaya konulmuştur.
