Nile Tilapia Oreochromis Niloticus

Tilapia fish farming with the aquaponic is a system of cultivation that can save land use and increase the efficiency of nutrient utilization of residual feed and fish metabolism by the plant. This research aimed to analyze the influence of different plant densities on growth, survival and the comparison of length and weight of tilapia (Oreochromis niloticus) in aquaponic system with dense plant. The experimental design used was Completely Randomized Design in time with three treatments and three replications with the level of density of vetiver (Vetiveria zizanioides) tested in this study was 400 g, 800 g and without vetiver. Nile tilapia (Oreochromis niloticus) was used with weight of 14 g, average length of 8-9 cm, and the experiment lasted for 42 days. The observed parameters was the growth of length and weight, length-weight relationship, and the survival rate. The results showed that the highest increase was in the treatment of 800 g vetiver plants with the growth of 19 g, the length increase of 2.64 cm and the survival rate of 100 ± 0.00 %. The lowest value was in the control. The use of aquaponic system in nile tilapia management with vetiver and control treatment had significant effect (P <0.05) on weight gain, length increase, and survival rate of tilapia. Water quality in all treatments generally reflected a range within tolerable limits and not harmful to tilapia growth.AbstrakBudi daya ikan nila dengan sistem akuaponik merupakan sistem budi daya yang dapat menghemat penggunaan lahan dan meningkatkan efisiensi pemanfaatan hara dari sisa pakan serta metabolisme ikan oleh tanaman. Penelitian ini bertujuan untuk menganalisis pengaruh padat tanaman yang berbeda terhadap pertumbuhan, sintasan dan perbanding-an panjang dan bobot ikan nila (Oreochromis niloticus) pada sistem akuaponik dengan padat tanaman yang berbeda. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan tiga perlakuan dan tiga kali ulangan dengan tingkat kepadatan vetiver yang diuji dalam penelitian ini adalah 400 g, 800 g dan tanpa vetiver. Ikan yang digunakan  adalah ikan nila dengan bobot 14 g, panjang rata-rata 8-9 cm, dan dipelihara selama 42 hari. Parameter yang diamati adalah pertumbuhan bobot, hubungan panjang-bobot, pertambahan panjang dan sintasan. Hasil peneli-tian menunjukkan bahwa peningkatan nilai tertinggi terdapat pada perlakuan tanaman vetiver 800 g dengan pertam-bahan bobot sebesar 19 g, pertambahan panjang sebesar 2,64 cm dan sintasan ikan sebesar 100±0,00 %. Nilai teren-dah terdapat pada kontrol. Penggunaan sistem akuaponik pada pemeliharaan ikan nila dengan perlakuan vetiver dan kontrol berpengaruh nyata (P<0,05) terhadap pertambahan bobot, pertambahan panjang, dan sintasan ikan nila. Kua-litas air pada semua perlakuan secara umum menggambarkan kisaran yang masih berada dalam batas toleransi dan tidak membahayakan bagi pertumbuhan ikan nila.

This study aims to apply vaccination against bacterial disease. The purpose of vaccination is to trigger the immune respone both non-specific and specific of fish against bacteria Motile Aeromonas Septicaemia (MAS) caused by Aeromonas hydrophila. The vaccination for fish with different ages: 2-3 weeks and 5 weeks were done using immersion method. The fish were re-vaccinated (booster) after two weeks of the first vaccination. The survival rate was < 50 % for juveniles 2-3 weeks and > 50% for juveniles 5 weeks. Survival rate for juveniles 5 weeks was higher than juveniles of 2-3 weeks. This shows that organs of juveniles of 5 weeks were more complete than the 2-3 weeks juveniles. The age of fish is one of the important factors for successfully vaccination. Penelitian ini bertujuan untuk melakukan penerapan vaksinasi terhadap penyakit bakterial. Vaksinasi ditujukan untuk merangsang respon kekebalan non- spesifik dan spesifik pada tubuh ikan terhadap penyakit Motile Aeromonas Septicaemia (MAS) yang disebabkan oleh bakteri Aeromonas hydrophila. Vaksin diberikan pada benih ikan nila yang berbeda umur yaitu 2-3 minggu dan 5 minggu dengan menggunakan metode perendaman. Ikan divaksinasi ulang (booster) setelah 2 (dua) minggu dari vaksinasi yang pertama. Prosentase kelangsungan hidup < 50 % untuk benih umur 2-3 minggu dan > 50% untuk benih umur 5 minggu. Jumlah kematian benih umur 2-3 minggu lebih tinggi dari 5 minggu. Hal ini menunjukkan bahwa fungsi organ benih umur 5 minggu telah lebih lengkap dari pada benih umur 2-3 minggu. Umur ikan merupakan salah satu faktor penting penentu keberhasilan suatu kegiatan vaksinasi.

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.

AbstractThe aim of this research was to find out optimum percentage of given fermentation the prawn waste flour in artificial feed on growth of black nile tilapia. The treatment of this research was giving fermentation the prawn waste flour in artificial feed i.e. 0%, 2,5%, 5%, 7,5%, 10%. Each treatment was repeated 4 times. Feed compositon was made of isoprotein. Fishes weight were about 6.1 – 6.8 g. Fishes were cultured with stocking rate 3 fish per 20 liter water and the fishes were reared for 40 days. Feed amount that consumed by fishes was measured every day to calculate feed conversion ratio. The calculation of fishes amount was done in beginning and end of research to count survival rate of fishes. Water quality was measured on beginning, middle and end of research. The design of this research was Completely Randomized Design. Data analysis used Analysis of Variance (ANOVA) to know the effect of the treatment and that difference among the treatment used Duncan's Multiple Range Test (DMRT). The result of the research showed that the highest growrth rate were attained on feed containing 10% of fermented prawn waste flour. The best feed convertion ratio were attained on feed containing 10% of fermented prawn waste flour.

Water Melon

The nutritive potential of water melon (Citrullus lanatus) seed meal as dietary protein source in the diet of Nile tilapia (Oreochromis niloticus) using growth performance and nutrient utilization were evaluated in a 56 day feeding trial. One hundred and fifty tilapia fingerlings of average weight 6.12±0.05g were acclimatized for a week, weighed and allotted into five dietary treatments; containing 0, 15, 30, 45 and 60% Citrullus lanatus replacement levels with soybean meal respectively. The diets (35% crude protein and 10% lipid) were isonitrogenous and isolipidic. Each treatment was replicated three times with ten fish per replicate. Fish were fed 5% body weight on two equal proportions per day to determine weight gain, percentage weight gain, specific growth rate, food conversion ratio, protein efficiency ratio and net protein utilization. The result from the study indicated that there was no significant (p>0.05) differences in the FCR and PER between the fish fed control diets and the fish fed test diets.
