Clarias gariepinus Balıklarının Yemlerine Farklı Düzeylerde Fermente Mango Çekirdeği ile Beslemenin Yavruların Büyüme Performansına Etkisi

Bu araştırmanın amacı, meyve işleme ve tüketiminden kaynaklanan tarımsal atıkların değerlendirilmesidir. Bu atıklar çevresel rahatsızlıklara yol açmaktadır ve bu ürünlerin su ürünleri yemlerine enerji kaynağı olarak katılması düşünülmüştür. Meyve işlemeden kaynaklanan atıkların kullanımı üç tekerrürlü olarak tanklarda yürütülmüştür. Ortalama Ağırlık Kazancı (MWG) en yüksek T1 (756.37 ± 13.61g) grubunda tespit edilmiş ve diğer gruplarla önemli derecede farklı bulunmuştur (P <0.05). Yem Dönüşüm Oranı (FCR) en yüksek T4 (1.46 ± 0.18 g) ve en düşük T1 (0.99 ± 0.01 g) grubundan elde edilmiştir. Spesifik Büyüme oranı (SGR) T4 grubunda diğer gruplara göre önemli ölçüde farklı bulunmuştur. Yem alımı ve yem maliyeti, MSKM'nin dahil edilme seviyesi ile azalırken, net kar T1 ve T3 grubunda benzerdi(P> 0.05). Deneme yemleri, balıkların hayatta kalması üzerinde hiçbir etki göstermedi. Sonuç olarak, yayın balıklar üzerinde herhangi bir etki yapmadan MSKM'nin% 50 seviyesinde ikame edilmesi büyüme performansını iyileştirilebilir.

Effect on growth Performance of Clarias gariepinus Juveniles Fed Fermented Mango Seed Kernel Diet at Different Inclusion Level

The main objective of this research was in the utilization of agro-wastes from fruit processing and consumption. This waste has resulted to environmental nuisance and the need for incorporation into aquaculture feed as energy source is inevitable. The utilization of waste from fruit processing can be used to reduce the cost of feed production. This research utilized fermented Mango Seed Kernel Meal (MSKM) as a replacement for maize in the diets of Clarias gariepinus juveniles. A 40% isonitrogenous diet was formulated ât inclusion levels of T1 (0%), T2 (25%), T3 (50%), T4 (75%), and T5 (100%) MSKM and fed at 3% body weight. One hundred and fifty (150) Clarias geriepinus juveniles average, the weight of 10.00g±0.14 were randomly allocated to Treatments in plastic tanks (49x33.5x33.5cm) at 10 fish per treatment/tank in triplicate. Mean Weight Gain (MWG) was highest in T1 (756.37±13.61g) and significantly differs (P<0.05) from other treatments. Feed Conversion Ratio (FCR) was highest in T4 (1.46±0.18g) and lowest in T1 (0.99±0.01g). Specific Growth Rate (SGR) was significantly different in T4 when compared to other treatments. Feed intake and feed cost decreased with the inclusion level of MSKM while net profit was not significantly different (P>0.05) in T1 and T3. Profit index and net profit were significantly compared in T2, T3, and T5. The diet showed no implication on fish survival. In conclusion, the growth performance of Catfish could be improved by substituting MSKM at 50% level without implication on cultured fish.
