A preliminary study on the utilization of hazelnut meal as a substitute for fish meal in diets of European sea bass (Dicentrarchus labrax L.)

Bioactive, functional and edible film-forming properties of isolated hazelnut (Corylus avellana L.) meal proteins

“…The TPC determined for the hazelnut meal is higher than those of 46.8% determined by Emre et al (2008) for Turkish hazelnut meal and those of 44.8% determined by Dogan and Erdem (2010) for the dry weight of similar meals. These results clearly showed that the protein content of hazelnut meal was comparable with that of soybean meal which could vary between 48.5% and 58.1% in dry weight basis (Thakur & Hurburgh, 2007).…”

“…Due to its nutritive value and high protein content, the hazelnut meal obtained from oil extraction is mostly employed as animal feed (Xu & Hanna, 2011). In fact, recent studies showed that the Turkish hazelnut meal can successfully be used in feeding juvenile rainbow trout (Dogan & Erdem, 2010) and European sea bass (Emre, Sevgili, & Ş anlı, 2008) as alternative to fish meal and soybean meal. There are also studies to use Turkish hazelnut meal in feeding of broiler chickens (Erener, Ak, & Ocak, 2009).…”

“…, Survival rate (SR) (%) =100×(final fish number / initial fish number) in sea bream feeds. Whereas Emre et al (2008b) confirmed that growth performance and body composition are not influenced by HM use up to 30 % in sea bass feeds. On the other hand, Ergun et al (2008) confirmed that HM can be used successfully in place of 20 % of soybean meal without causing growth failure in feeds of turbot.…”

“…There was more growth in these groups with the increase in feed uptake. Emre et al (2008a), in their study with sea bream, Emre et al (2008b), in their study with sea bass, and Bilgin et al (2007), in their study with rainbow trout, confirmed that feed conversion ratio (FCR) was not influenced by the HM rate increase in the feed. Similarly, the present study indicated that FCR was not influenced by the HM rate increase up to 50%.…”

“…In addition, there are studies on the use of HM in mixed fish feed. Mixed fish feed with HM have been tested on trout (Dogan 2005;Bilgin et al 2007), carp (Buyukcapar and Kamalak 2007), sea bream (Emre et al 2008a); sea bass (Emre et al 2008b) and turbot (Ergun et al 2008) respectively. In the aforementioned studies, HM was compared to FM, or the ratio at which it can be substituted for soy meal or FM was investigated.…”
