AB  - The recycling of fish which cannot be used for human consumption and fish processing industry wastes into feed raw materials is an environmentally friendly method that ensures the efficient and sustainable use of resources. In this study, fish silage was prepared from twaite shad fish, which could not been utilised as human food, by using formic acid application and the nutrient content and fatty acid composition of the produced silages were investigated. The dry matter values of the silages varied between 26.14% and 26.63%, crude protein values between 73.79% and 78.55%, and fat values between 5.09% and 5.46%. It was determined that the amount of crude protein decreased in silages produced by using low doses of formic acid (p0.05). Especially crude protein and PUFA content of the produced silages showed that twaite shad fish silage can be utilised in fish feed. The use of fish silage with valuable nutrient content as feed raw material will provide both economic gain and contribute to the protection of the environment.

N2  - İnsan tüketimine sunulamamış balıkların ve su ürünleri işleme sanayi atıklarının, balık silajı olarak yem hammaddesine dönüştürülmesi, kaynakların etkin ve sürdürülebilir kullanımını sağlayan çevre dostu bir yöntemdir. Bu çalışmada, insan gıdası olarak değerlendirilememiş tirsi balıklarından, formik asit uygulamasıyla balık silajı üretimi yapılmış ve üretilen silajın besin içeriği ve yağ asidi kompozisyonu incelenmiştir. Silajların kuru madde içeriği %26,14 ile %26,63 arasında, ham protein miktarı %73,79 ile %78.55 arasında, yağ miktarı ise %5,09 ile %5,46 arasında değişim göstermiştir. Düşük dozda formik asit kullanılarak üretilen silajlarda ham protein miktarının düştüğü belirlenmiştir (p0.05). Üretilen silajların özellikle ham protein ve PUFA içeriği, tirsi balığı silajının balık yemlerinde kullanılabileceğini göstermiştir. Değerli besin içeriğine sahip balık silajının yem hammaddesi olarak kullanılması, hem ekonomik kazanç sağlayacak hem de çevrenin korunmasına katkıda bulunacaktır.
