“…According to Maina et al (2003) and Bahurmiz and Ng (2007), the fatty acid composition of many fish resembles that of their food. This was also proved in many studies in which FM or fish oil was replaced by non-conventional sources of protein or lipid (Bell et al, 2002;Cabellaro et al, 2002;Williams et al, 2003;Francis et al, 2006;Xue et al, 2006;Gümüş and Erdogan, 2010;Hu et al, 2013).…”

“…On the contrary, Nengas et al (1999) reported that PBM can be used without amino acid supplementation to replace 50% of the FM in diets for gilthead seabream. Aydın and Gümüş (2013) also found PBM was able to replace 50% of Numerous studies have shown that fatty acid profiles of fish tissue reflect the dietary fatty acid profiles (Francis et al, 2006;Xue et al, 2006;Bahurmiz and Neg, 2007;Gümüş and Erdogan, 2010;Hu et al, 2013). In the present study, considerable differences were, nevertheless, observed in fatty acid profiles of muscle of fish fed diets progressively replaced of FM with PBM, and some fatty acids inclined to increase or decrease in the muscle of fish (Table 6).…”

The effect of replacement of fish meal (FM) with graded level of poultry by-product meal (PBM) in diets on growth performance and fatty acid composition of carp fry (Cyprinus carpio) was examined in the experiment. Five isonitrogenous (34% crude protein), isolipidic (9% crude lipid) and isoenergetic (15.0 MJ/kg DE) experimental diets replacing 0 (control group), 25, 50, 75 and 100% of FM protein by PBM protein were formulated with lysine, methionine and threonine supplementation in order to balance the amino acid profiles of the experimental diets. Each diet was fed to twice daily to apparent satiation of groups of twenty fry (mean weight 0.39 g fish -1) stocked into 65L glass aquaria to maintain three replicates per treatment. At the end of the experiment, body weight gain, specific growth rate, protein efficiency ratio and feed conversion ratio decreased with increased dietary replacement of FM with graded levels of PBM, while condition factor, hepatosomatic indices, viscerosomatic indices and whole body composition did not exhibit significant differences among the experimental groups (P>0.05). There were significant differences in total fatty acid composition of each experimental group. Values of Σn-3 polyunsaturated fatty acids and Σn-3/Σn-6 ratio in the muscle of fish decreased. No significant differences in saturated fatty acids values were observed in fish, while monounsaturated fatty acids values increased as the PBM level increased in the diet.

However, FM is the most expensive and limited availability (Nguyen et al., 2009). Hence, the aquafeed industry has to search for less expensive alternative protein sources to reduce Sazan (Cyprinus carpio) Yavrusunun Büyüme Performansı ve Yağ Asit Kompozisyonu Üzerine Tavuk Kesim Atıkları Ununun Etkisi ÖzetBu çalışmada, aynalı sazan (Cyprinus carpio) yavru yeminde balık unu proteini yerine tavuk kesim atıkları ununun (TKAU) artan seviyelerde kullanımının balıklarda büyüme performansı ve yağ asidi kompozisyonu üzerine etkisi araştırılmıştır. Protein (%34 ham protein), yağ (%9 ham yağ) ve enerji (15,0 MJ/kg SE) değerleri eşit olmak üzere balık unu proteini yerine TKAU proteini %0 (kontrol grubu), %25, %50, %75 ve %100 oranında ilave edilerek beş farklı deneme yemi hazırlanmıştır. Ayrıca hazırlanan yemlerin amino asit içeriklerini dengelemek için lisin, metiyonin ve tironin ilave edilmiştir.Deneme, 65L'lik 15 cam akvaryumun her birinde 20 balık (ortalama ağırlık 0,39 g) olacak şekilde üç tekrarlı olarak planlanmıştır. Deneme grubu balıkları günde iki kez doyuncaya kadar 13 hafta süre ile beslenmiştir. Deneme sonunda, vücut ağırlık kazancı, spesifik büyüme oranı, protein etkinlik oranı ve yem dönüşüm oranı TKAU'nun artan oranlarını içeren yemlerle beslenen balıklarda azalırken, kondüsyon faktörü, hepatosomatik indeks, visserosomatik indeks ve balık eti kimyasal kompozisyonunda önemli bir farklılık görülmemiştir (P>0,05).

“…Therefore, researchers have recently stated their studies that the monitoring of this organ is important in FM replacement studies (Caballero et al 2004, Rašković et al 2011. Histological changes in liver and intestine of fi sh fed diets containing various levels of alternative protein sources have been previously demonstrated in different fi sh species by several authors (Merrifi eld et al 2009, Nogales Mérida et al 2010, Gai et al 2012, Martínez-Llorens et al 2012, Hu et al 2013, Hlophe and Moyo 2014. Thus, the objective of this study was to investigate fatty acid composition and liver histology of Nile tilapia fry when FM protein is replaced by PBM protein as an alternative protein source.…”

Aydın B., Gümüş E., Balcı B.A. 2015. Effect of dietary fi sh meal replacement by poultry by-product meal on muscle fatty acid composition and liver histology of fry of Nile tilapia, Oreochromis niloticus (Actinopterygii: Perciformes: Cichlidae). Acta Ichthyol. Piscat. 45 (4): 343-351.Background. Poultry by-product meal (PBM) has been used as a potential substitute for fi sh meal (FM) in aquaculture feeds. However, there are concerns that high replacement of FM protein with PBM protein could adversely affect of the fi sh fl esh quality, due to lowered (Σ n-3 PUFA) fatty acids content. While fatty acid composition of fi sh muscle has critical importance in human nutrition, the fi sh liver is a key organ that facilitates digestion of feed and plays an important role in fi sh digestive system. As has been recently demonstrated, the monitoring of this organ is important in FM replacement experiments. The aim of this study was to evaluate the potential use of PBM on the fatty acid composition of the muscles and on the histological structure of the liver of fry of Nile tilapia, Oreochromis niloticus (Linnaeus, 1758). Materials and methods. Five isonitrogenous (34%, crude protein), isolipidic (9%, crude lipid), and isoenergetic (15 MJ · kg -1 , digestible energy) diets were formulated to contain graded levels of PBM, where FM protein was replaced with PBM protein at 0%, 25%, 50%, 75%, and 100% level with lysine-, methionine-, and threonine supplementation. Triplicate groups of 20 fi sh (mean weight 0.879 g) were fed three times daily to apparent satiation for 12 weeks. Results. At the end of the experiment, the fatty acid contents of the fi sh muscle were signifi cantly affected by the experimental diets. As the FM content decreased, there was no reduction of saturated fatty acids; the diet with lowest FM protein percentage having the highest monounsaturated fatty acids and lowest polyunsaturated fatty acids (PUFA) proportions. The replacement of FM by PBM had a profound impact on the fatty acid composition of tilapia muscle with an increase in Σ n-6 PUFA and a decrease in the Σ n-3 and Σ n-3 : Σ n-6 PUFA ratio. The histological examination of liver tissue in all treatments of this study, revealed no histological abnormalities. Conclusion. The replacement of FM with PBM (range 0%-100%) signifi cantly decreases the amount of docosahexaenoic acid (12.2%-1.2%) and eicosapentaenoic acid (4.4%-0.4%) in the muscle of fi sh. Therefore, further study is needed with PBM as a substitute of FM to determine acceptable fatty acid composition for commercial production.
