dc.description.abstractThe study investigated how the sources of fish meal and the amount of lipids in the diets of juvenile turbot (Psetta maxima) affected growth, feed utilization, body composition, and nutrient balance. The fish were fed with feed produced using two different fish meals for 50 days: white fish meal (WFM) from Alaska cod, Gadus chalcogrammus and brown fish meal (BFM) from Black Sea anchovy, Engraulis encrasicolus. The diets prepared as BFM-HL (Brown fish meal- high lipid), BFM-LL (Brown fish meal- low lipid), WFM-HL (Whitefish meal-high lipid), WFM LL (Whitefish meal-low lipid) contained 53% protein and 10–14% lipid. Fish meal sources and lipid levels had a substantial (P< 0.05) impact on final weight, specific growth rate (SGR), daily feed intake (FI), feed conversion rate (FCR), protein efficiency rate (PER), nitrogen intake, gain, and loss, and lipid intake, gain, and retention. WFM-HL fed fish showed the best SGR, FCR, and PER results. When compared to the other diets, the WFM-HL diet's better protein utilization led to a considerably higher (P< 0.05) nitrogen retention. The fish-fed WFM-HL and BFM-HL diets had higher lipid retention values. Protein, lipid, and ash levels in the whole fish body were significantly (P< 0.05) influenced by the dietary fish meal source and lipid level. Compared to diets containing BFM, the results suggested that employing WFM in diet would be more promising in terms of higher growth performance and nutrient utilization. Also, with regard to experimental design, dietary lipid levels of 14% could result in greater growth than the diet containing 10% lipid, regardless of fish meal sources and levels.
dc.description.abstractBu çalismada, yavru kalkan baligi yemlerinde bulunan balik unu kaynaklarinin ve lipid düzeylerinin büyüme, yemden yararlanma, vücut kompozisyonu ve besin dengesi üzerine etkileri arastirilmistir. Baliklara 50 gün boyunca iki farkli balik unu kaynagi (Karadeniz hamsisinden (Engraulis encrasicolus) üretilmis kahverengi balik unu, KBU ve Alaska morina baligindan (Gadus chalcogrammus) üretilmis beyaz balik unu, BBU) ve iki farkli lipid seviyesi içeren yemler verilmistir. KBU-YL (Kahverengi balik unu –yüksek lipid), KBU-DL (Kahverengi balik unu –düsük lipid), BBU-YL (Beyaz balik unu –yüksek lipid), BBU- DL (Beyaz balik unu –düsük lipid) seklinde hazirlanan diyetler %53 protein ve %10–14 lipid içeriyordu. Deneme sonunda, final agirlik, spesifik büyüme orani (SBO), günlük yem tüketimi (GYT), yem dönüsüm orani (YDO), protein verimlilik orani (PVO), nitrojen tüketimi, kazanimi, kaybi ve lipid tüketimi, kazanimi, tutulmasi degerlerinin yemdeki protein kaynagi ve lipid seviyesinden önemli ölçüde (P? 0,05) etkilendigi tespit edilmistir. En iyi SBO ve YDO, BBU-YL yemi ile beslenen gruptan elde edilmistir. Nitrojen tutulumu, en iyi protein degerlendirmenin tespit edildigi BBU-YL grubunda diger gruplara kiyasla önemli derecede P
