Red Nile Tilapia  of Larasati strain (Oreochromis niloticus)have capability to digest feed quite efficient, able to grow faster and diseases resistant.  They are also tolerant to high salinity and more resilent to environmental change, therefore very prospecytive to be cultivated in tambaks (brackishwater pond).  The objective of present work was to determine the effect of larvae stocking density and feed ration on the growth and survival rate of Nile Tilapia in brackishwater pond. The larvae was hacthed in freshwater and acclimatized gradually in brackishwater media and then reared ini cage size of 1x1x1,5meter3with different food ration (3, 5 and 7% body weight)andstocking density of 10, 15, 20 indv./m2).The result showed that the more food ration gave the better growth rate of larvae in stocking density of 10 and 15 indv./m2, the best food ration in 20 indv./m2 was 5% body weight. Upon that result it is recommended to  stock the alvae at level of 20 indv./meter and gave food of 5% per body weight.  The treatments was not influenced the survival rate of fish cultured.  Keywords :Fish Nila Larasati , growth, feed ration, stocking density  Ikan Nila Larasati memiliki kemampuan mencerna makanan secara efisien, memiliki pertumbuhan yang cepat serta lebih resisten terhadap penyakit, daya adaptasi luas dan toleransinya yang tinggi terhadap berbagai kondisi lingkungan sehingga prospektif dibudidaya di tambak.  Penelitian ini bertujuan untuk melakukan kajian tentang pengaruh padat tebar dan ransum pakan terhadap pertumbuhan dan kelulushidupan ikan Nila Larasati yang dipelihara pada tambak air payau.  Ikan Nila Larasati dibenihkan di lingkungan air tawar dan diaklimatisasi secara bertahap di media air payau sebelum digunakan dalam penelitian ini. Percobaan pemeliharaan ikan Nila Larasati dilakukan pada karamba berukuran 1x1x1,5meter3dengan ransum pakan(3, 5 dan 7% bobot biomasa ikan) dan padat penebaran yang berbeda (10, 15, 20 ekor/m2).Hasil penelitian menunjukkan pemberian ransum pakan harian baik 3, 5 dan 7% perhari pada ikan nila dengan kepadatan 5, 10 dan 20 ekor/meter menunjukkan hasil pertumbuhan berat mutlak yang relatif baik, namun untuk efisiensi pakan disarankan untuk melakukan penebaran 20 ekor/meter dengan ransum 5% berat biomasa ikan perhari. Kelulushidupan ikan Nila Larasati tidak dipengaruhi oleh perlakuan.  Kata Kunci : Ikan Nila Larasati , pertumbuhan, pakan, padat penebaran

This study aimed to evaluate the effect of probiotic on growth and survival of tilapia (Oreochromis niloticus) against Streptococcus agalactiae infection. The test materials used were commercial probiotic bacteria and Streptococcus agalactiae. The probiotic bacteria were administered by mixing into the feed with a dose of 0 mL (without probiotics), 10 mL / kg of feed, 15 mL / kg of feed and 20 mL / kg of feed.  Feed was given 3 times a day at 08.00, 12.00 and 16.00 for 21 days. After that, the challenge test was done with Streptococcus  agalactiae bacteria by cohabitation. Bacteria with a density of 107 cells / mL were mixed into the water and allowed for 2 hours. The result showed that B treatment (10 mL / kg of feed) gave the best result with 93,33 percent of  survival rate. Statistical analysis showed that the survival of fish in treatments B, C and D was significantly different from treatment A (P <0.1). However, there was no significant difference between treatments B, C, and D. It was also found that the addition of probiotic in feed did not affect the growth of Nile tilapia (Orechromis niloticus). Keywords : Probiotic bacteria,  nile tilapia,  Streptococcus  agalactiae, growth,  infection

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.

Laju pertumbuhan dan tingkat reproduksi yang tinggi merupakan karakteristik unggul yang dimiliki ikan nila sebagai komoditi budidaya. Tingkat reproduksi yang tinggi menyebabkan terjadinya pematangan gonad sebelum mencapai ukuran produksi dimana hal tersebut dapat merugikan pembudidaya, karena saat ikan mengalami matang gonad energi hasil asimilasi pakan sebagain besar akan dialokasikan untuk perkembangan gonad dan menghambat pertumbuhan somatik. Pemanfaatan senyawa aktif dari bahan alami biji pepaya dapat menjadi solusi untuk meningkatkan pertumbuhan ikan yang dibudidayakan sekaligus menjaga keamanan pangan dan konsumen. Penelitian ini bertujuan untuk mengetahui pemanfaatan tepung biji pepaya terhadap respons pertumbuhan dan tingkat kelangsungan hidup ikan nila. Ikan nila diberi perlakuan dengan lima dosis tepung biji pepaya berbeda (0, 1, 3, 5 dan 7 g/kg pakan) secara oral berdasarkan feeding rate 5% dengan tiga ulangan selama 30 hari pemeliharaan. Hasil penelitian menunjukkan dosis 5 g/kg meningkatkan pertumbuhan bobot tubuh tertinggi sebesar 547 g dibandingkan kontrol sebesar 406 g. Sejalan dengan pertumbuhan bobot tubuh, dosis 5 g/kg menghasilkan tingkat kelangsungan hidup ikan nila sebesar 100% dibandingkan kontrol sebesar 66%. Dari hasil yang diperoleh dapat disimpulkan bahwa tepung biji pepaya dengan dosis 5 g/kg pakan dapat meningkatkan pertumbuhan dan tingkat kelangsungan hidup ikan nila selama 30 hariHigh growth rate and high reproductive cycle are some economical triats on nile tilapia. This is a setback for nile tilapia culture because when the fish reach gonad maturity before reach market size, all the energy demand will flow to reproduction and can cause stunt growth. The utilization of natural compound from papaya seeds can be a solution to enhance growth of farmed nile tilapia and for consumer and food safety. This research aim to know how papaya seed powder can enhance growth and survival rate of nile tilapia. This research conducted into five groups of 5 papaya seeds powder dosage (0, 1, 3, 5 and 7 g/kg) that feed orally to the treatment fishes. Result showed the fishes feed with 5 g/kg papaya seed experienced highest growth performance 547 g compare to control which is 406 g. Same as growth performance, survival rate shown that group feed with 5 g/kg papaya seed had 100% survival rate compare with control which is 66% during treatment periods. Base on this result, we can make conclusion that fish feed with 5 g/kg of papaya seed have a better growth performance and survival rate compare with control group for 30 days treatment periods

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.
