“…Chemical fish waste silage can be prepared by direct acidification with organic acid, inorganic acid, or mixture of both (Copes et al, 2006;Fagbenro & Jauncey, 1993;Gullu et al, 2015;Toledo Pérez & Llanes Iglesias, 2006). While the cost of organic acids is higher than mineral acids such as hydrochloric acid and sulfuric acid, handling inorganic acids requires trained operator and safety equipment.…”

Introduction. Different fishing activities generate a waste volume related to the processing species (viscera, heads and bones), the discards of the companion fauna, species of low commercial value and the losses related to handling problems. Fish meal production is the most common process for recovery nutrients from these fish processing byproducts. However, those places with reduced infrastructure or where the volume of wastes produced do not justified the economic equation for conversion into fish meal or oil, the biological silage could be the technology of choice to promote a sustainable waste management. Objective. To compilate, organize and summarize literature related to biological fermentation of fish waste and its applications. Development. A bibliographic review was carried out (January 1994 - December 2020) referring to the comprehensive use of fishing residues mainly focused on the use of lactic acid bacteria in fish waste fermentation. The information was organized in different sections: fish silage, lactic acid bacteria and carbohydrate sources for biological silage. Conclusions. The studies analyzed in this review highlight the possibility of using a wide variety of carbohydrate sources, biological starters and fish waste fermentation conditions. The satisfactory results show the potential use of fish waste in different applications. This work could contribute to the fisheries that decide to adopt this kind technology in order to provide an innovative and viable recycling bioeconomy.

The evaluation of seafood processing wastes is an important issue in terms of both preventing environmental pollution and adding value to these wastes economically. The most practical method that can convert seafood processing waste into a valuable feed source and plant fertilizer is to make silage. In this study, the ripening times and nutritional components of fish silages prepared with direct addition of lactic acid bacteria culture (Streptococcus thermophilus), acidifying chemicals (formic acid) and yogurt, which is a fermented food, were compared. In the research, sardine fish (Sardina pilchardus) wastes (head, skin, bones, internal organs, etc.) were used in fish silage production. It was observed that all fish silages completed the ripening phase within a maximum of 10 days. It was determined that the moisture, ash, protein and lipid contents of the groups prepared with acid, bacteria and yoghurt ranged between 63-66%, 5.6-5.7%, 11.3-11.8% and 12.18-13.65%, respectively. As a result of the research, it was observed that fish silages made with the addition of yoghurt as an alternative to silages made with direct addition of pure bacterial culture or acid addition met the expectations in terms of both ripening time and nutrient components.

Çalışmada, kültür deniz balıkları işleme endüstrisi artıklarından formik asit hidrolizi ile balık silajı ve balık yağı üretilmesi, elde edilen ürünlerin kimyasal ve mikrobiyolojik kalitesinin tespiti ve balık yağının yağ asit kompozisyonun belirlenmesi amaçlanmıştır. Bu kapsamda yapılan çalışmalar sonucunda elde edilen balık silajının nem içeriği %80,40, tüm aşamalarda ürün kalitesinin önemli göstergelerinden birisi olan pH değerinin de 3,62 ile 3,89 arasında değişim gösterdiği tespit edilmiştir. Balık silajının kuru ağırlıktaki kuru madde, ham protein, ham yağ ve ham kül değerleri sırasıyla %19,60, %48,26, %15,17 ve 17,01 olarak bulunmuştur. Ayrıca ürünün toplam mezofilik aerob bakteri, toplam psikrofilik aerob bakteri ve toplam koliform bakteri bakımından güvenli olduğu, üretilen balık yağının toplam doymuş yağ asidi miktarı %20,64, doymamış yağ asidi miktarı ise %70,49 olarak belirlenmiştir. Toplam n-3 yağ asidi miktarı %12,15, toplam n-6 yağ asidi miktarı %19,87 ve n-3/n-6 oranı da 0,61 olarak saptanmıştır.
