Nile Tilapia Oreochromis Niloticus

Although fumonisins are identified as responsible for alterations in weight gain, little information is available on their effects on expression of growth-related genes, especially for Nile tilapia (Oreochromis niloticus) fingerlings. In this study, Nile tilapia fingerlings were treated with increasing levels of fumonisin B1 (FB1) and fumonisin B2 (FB2) (diets of 0, 20, 40, and 60 mg/kg) to evaluate their effects on weight gain (WG), feed intake (FI), feed efficiency (FE), growth hormone receptor (GHR) and insulin growth factor 1 (IGF-1) mRNA expression in liver of this fish. All variables were evaluated at 15 and 30 days of treatment. Diet containing 0 mg fumonisin/kg was used as control treatment. Treatment with 20, 40, and 60 mg fumonisin/kg of diet significantly reduced WG (P<0.0001) and FE (P<0.0001), while GHR and IGF-1 mRNA expression was reduced both at 15 and 30 days of treatment. Feed intake was not affected by diets in any of the evaluated periods. These results indicate that fumonisins (FB1 + FB2) affect the growth of Nile tilapia fingerlings through mechanisms that involve reduction of GHR and IGF-1 expression.

Statistical Results

Silage is prepared by adding the probiotic into the material of bones and flesh of waste from the market.  Silage is used as element substituted with fish meal as feed for tilapia with initial weight of 19.14 to 24.86 grams and a length of 3-5 cm.  There are three types of feed using silage replacing fish meal as much as 10% (treatment A), 20% (treatment B) and 30% (treatment C) and a control used commercial feed (treatment D).  The results obtained are feed in treatment D gives very significant results to the three other feed (A, B and C) in the case of weight, rate of growth and feed efficiency; but in a further test of Duncan, statistical results showed that feed C and D more efficient than feed A.Keywords: low cost artificial feed, silage, growth, tilapia ABSTRAKSilase dipersiapkan melalui penambahan probiotik ke dalam bahan tulang dan daging dari bahan-bahan yang tidak terpakai yang diambil dari pasar.  Silase ini digunakan sebagai elemen yang disubsitusikan dengan tepung ikan untuk diberikan sebagai pakan pada ikan nila dengan berat awal 19,14-24,86 gr dan panjang 3-5 cm.  Ada tiga jenis pakan dengan menggunakan silase menggantikan tepung ikan sebanyak 10 (perlakuan A), 20 (perlakuan B) dan 30% (perlakuan C) dan sebagai kontrol digunakan pakan komersial (perlakuan D). Hasil yang diperoleh adalah pakan uji pada perlakuan D sangat memberikan hasil berbeda yang sangat nyata dengan ketiga pakan lainnya (A, B dan C) dalam hal pertumbuhan berat, laju pertumbuhan dan efisiensi pakan; namun pada uji lanjut Duncan, hasil statistik menunjukkan bahwa pakan C dan pakan D lebih efisien dibandingkan pakan A.Kata kunci: akuakultur, pakan buatan murah, silase, pertumbuhan, ikan nila
