Son yıllarda önemi giderek artan su ürünleri yetiştiriciliğinde özellikle balık kültürü ön plana çıkmıştır. Özellikle entansif yetiştiricilik konusunda araştırmalar yapılmasını gerektirmektedir. Entansif üretimde, balıkların besin madde ihtiyaçlarının optimal şekilde karşılaşması şarttır. Diğer bir deyişle besin ve besin maddelerinin daha dikkatli ele alınması gerekmektedir. Besin madde ihtiyaçlarının tam olarak karşılanmadığı koşullarda, balıkların bağışıklık sistemlerinin bozulması sonucu patojenlere karşı direncin azalmasından kaynaklanan hastalıkların yanında besinsel kaynaklı hastalıklar da ortaya çıkabilmektedir. Bu durum dikkate alındığında, çalışmada besinsel kaynaklı hastalıklar ve bu hastalıklara karşı alınması gerekli önlemler üzerinde durulmuştur. Bu araştırma, konuyla ilgili ön çalışma niteliğinde olup, önerilerde bulunulmuştur. Fish diseases related with feeding. Importance of aquaculture is going over everyyear. Fish culture has priority in aquaculture with its flesh quality, culture ability and nutritionaly qualty. In order to deplish feeding and nutrition, immune system of fishes would be broken down and pathogenic diseases with nutritional diseases would be sees. In this case, nutritional diseases and preventation of the fishes against this matter is hold. This study is including first knowledge for general.
Besinsel Katki Maddesi Olarak Kullanılan Mannanoligosakkaritin Çipura Balığının (Sparas aarata) Büyüme, Yem Degerlendirme ve Yasama Gücü Üzerine Etkisiu

Bu çalismada; çipura (Sparus aurata) beslemede mannanoligosakkaritlerin kullanilabilme imkani ve besin maddesi sindirimi üzerine etkileri arastinlmistir. Mannanoligosakkarit olarak, ekmek mayasinin (Saccharomyces cerevisiae) hücre duvarindan elde edilen Bio-Mos® kullanilmistir. In,I1±13,19 g ortalama agirligindaki baliklar 20.000±2io adet olacak sekilde 9 adet sekizgen agkafese stoklanmis ve her grup üç tekrarli olacak sekilde; 0/00 O,0/00 2 ve 0/00 4 oraninda Bio-Mos® katilarak hazirlanan yemlerle beslenmistir. Deneme sonunda Bio-Mos®'un 0/00 2 oraninda kullanilabilecegi ve gruplar arasinda; ham protein, ham yag, ham selüloz, ham karbonhidrat sindirimleri, agirlik artislari, yem dönüsüm oranlari ve ölüm oranlari bakimindan önemli fark bulunmustur. In this study, usage possibility of mannanoligosaccharide in gilthead sea bream (Sparus aurata) and its effects on digestibility of nutrients were investigated. BioMos derived from the cell wall of bread yearst was used as mannanoligosaccharide. Fish with in.ll ± i3. 19 g average weight were stocked to 9 octagonal cages each of which was included 20,000 ±2io fish in three replicates. 00/00, 20/00 and 40/00 of Bio-Mos were added to fish feeds. At the end of the study it was found that Bio-Mos can be used successfully at 20/00 rate in feeds. Significant differences were observed between groups with respect to crude protein, crude fat, crude cellulose, crude carbohydrate digestion, weight gains, feed conversation rate and mortalitiy rates
Preliminary Assessment of Dietary Mannanoligosaccharides on Growth Performance and Health Status of Gilthead Seabream Sparus auratus

A feeding trial was performed to assess the potential beneficial effect of two levels of mannanoligosaccarides (MOS) on the growth performance, feed utilization, hematological parameters, and liver histopathology of gilthead seabream Sparus auratus (also known as gilthead bream). Mannanoligosaccarides were added at the rates of 2 and 4 g/kg to a fish-meal-based control diet, and each diet was given (twice daily [midmorning and midafternoon] to apparent satiation) to triplicate groups of gilthead seabream growers (mean weight = approximately 170 g) in sea cages. The trial lasted 12 weeks, and the average ambient water temperature ranged from 19.6◦C to 24.7◦C during the experimental period. At the end of the experiment, fish attained market size (350–450 g) and their health status was evaluated by blood analysis and liver histology. There were no differences in survival rates among fish fed experimental diets. However, there were significant improvements in both growth and feed utilization among fish fed diets supplemented with MOS. Hemoglobin (Hb) and hematocrit (Ht) levels and erythrocyte, leukocyte, and thrombocyte (Thr) counts were unaffected by any dietary MOS. The levels of Hb (g/dL; mean ± SD) and Ht (%; mean ± SD) were 11.0 ± 2.5 and 45.6 ± 6.7 for the control group, 11.1 ± 1.7 and 39.3 ± 8.0 for the 2-g/kg group, and 11.2 ± 1.9 and 40.2 ± 8.4 for the 4-g/kg group. Themean Thr count ranged from 47.6 to 53.8 × 103/mm3. Despite the apparently higher Thr counts for fish fed diets supplemented with MOS, these differences were not significant. Moreover, no histopathological differences were observed in liver tissue cross sections between control and treatment groups. These results suggest that supplementation of diets withMOS had no significant effects on general fish health.
