ABTSRAKPemuliaan ikan nila di Indonesia merupakan kegiatan perekayasaan yang sangat penting dilakukan untuk menigkatkan mutu genetik ikan nila yang ada di masyarakat. Metode Seleksi Famili telah digunakan sebagai satu metode efektif untuk mendapatkan strain induk nila yang lebih unggul. Pada tahun 2005 telah berhasil membuat generasi pertama seleksi famili sebanyak 35 famili, tahun 2006 telah menghasilkan 49 famili dan tahun 2007 menghasilkan 39 famili. Masing-masing famili terdiri dari dua sub populasi yaitu induk jantan dan induk betina. Jumlah populasi hasil seleksi pada sub populasi jantan dan betina masing-masing dapat memenuhi jumlah top grad minimal 15 ekor jantan dan 15 ekor betina. Jumlah famili yang memijah 39 famili. Hasil cut off pada masing-masing sub famili mempunyai bobot rataan 120,14+7,3 g pada sub populasi jantan dan 97,36 + 2,6 g pada sub populasi betina. Mutu genetik yang diperoleh pada generasi F3 menghasilkan nilai heritabiliti sebesar 0,142 dengan respon seleksi 25,4 g. Proses seleksi masih perlu dilanjutkan kepada generasi ke-4 untuk memperoleh generasi yang lebih unggul.Kata Kunci: Tilapia, program pemijahan, seleksi familiABSTRACTGenetic improvement of tilapia in Indonesia is very important in order to improve the tilapia quality. Family selection method was known as an effective method to get higher quality brood stock. In 2005, 35 first generation of families selection were successfully done, in 2006, 49 families were produced and in 2007, 39 families were produced. Each family consisted of two sub population, i.e. male and female brood stocks. The number of male and female sub population selection could fulfill the top grade minimal number of 15 males and 15 females. 39 families spawned. The cut off results of each sub family had average body weight of 120.14 ± 7.3 g for male sub population and 97.36 ± 2.6 g for female sub population. The genetic quality which was obtained on F3 generation had a heritability value of 0.142 with selection respond 25.4 g.

ABSTRAKBudidaya ikan nila (Oreochromis niloticus) terus dikembangkan hingga saat ini. Berbagai teknologi dalam bidang perikanan telah diterapkan, salah satunya yaitu sex reversal dalam hal ini jantanisasi. Ikan nila jantan lebih cepat pertumbuhannya dari pada ikan nila betina sehingga dapat meningkatkan hasil produksi. Tujuan penelitian ini yaitu untuk mengetahui pengaruh pemberian tepung testis sapi dan dosis terbaik tepung testis sapi dalam pakan yang mengandung rGH terhadap rasio jenis kelamin, pertumbuhan dan kelulushidupan ikan nila. Bahan uji yang digunakan adalah larva ikan nila dengan stadia larva yang berumur 7 hari setelah lepas kuning telur dan memiliki bobot rata-rata 0,07 gram/ekor. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap 4 perlakuan dan 3 kali ulangan. Perlakuan dalam penelitian ini yaitu dengan menambahkan tepung testis sapi dengan dosis pada perlakuan A (0%/kg pakan), perlakuan B (3%/kg pakan), perlakuan C (6%/kg pakan) dan, perlakuan D (9%/kg pakan). Pakan pada setiap perlakuan dalam penelitian ini telah ditambahkan rGH dengan dosis 2 mg/kg pakan. Data yang diamati meliputi rasio jenis kelamin, laju pertumbuhan spesifik (SGR), dan tingkat kelulushidupan (SR) ikan nila. Hasil penelitian menunjukan bahwa perlakuan C (6% tepung testis sapi/kg pakan) memberikan hasil terbaik dimana nilai rasio jenis kelamin jantan sebesar 74,44±5,09% dan laju pertumbuhan spesifik sebesar 9,48±0,10% bobot/hari. Kesimpulan yang diperoleh dalam penelitian ini yaitu adanya pengaruh nyata terhadap rasio jenis kelamin dan tingkat pertumbuhan spesifik, namun tidak berpengaruh nyata terhadap tingkat kelulushidupan ikan nila dengan pemberian dosis tepung testis sapi terbaik adalah 6% tepung testis sapi/kg pakan.Kata kunci: Sex reversal; Tepung testis sapi; Pertumbuhan, rGH; NilaABSTRACTTilapia fish (Oreochromis niloticus)cultivation still continue to be developed until nowdays. Many fisheries technology had been applied, and one of them is sex reversal which is masculinization. Male tilapia fish grows faster than the female one, so this can boost the produce of the fish. This research aims to know the effect of cow testicle flour addition and determine the best dosage on the fish feed which contains rGH towards the male-sex ratio, growth, and survival rate of tilapia fish. The material which used in this research was tilapia fish (O. niloticus) which under the larvae phase 7 days post the separated egg yolk which have average weight of 0,07 grams/each. This research used experimental methods with Completely Randomized Design of 4 treatments and 3 times of repetitions. The treatments in this research was addition of different dosage of bull testicle which treatment A (0%/kg fish feed),treatment B (3%/kg fish feed), treatment C (6%/kg fish feed) and, treatment D (9%/kg fish feed). The fish feed in every treatment had been added with 2mg rGH/kg fish feed. Data observation during this research were male-sex ratio, specific growth rate (SGR), and survival rate (SR) of tilapia fish. Results of the research showed that treatment C (6%/kg fish feed) gave the best result as male-sex ratio by 74,44±5,09% and specific growth rate by 9,48±0,10% weight/day. Conclusion obtained from this research was: there was different result towards the male-sex ratio and specific growth rate, but there was no difference between the treatments towards the survival rate, the best bull testicle flour dosage was 6%/kg fish feed.

Lisin merupakan asam amino pembatas dalam pakan dikarenakan sumber protein nabati yang digunakan sebagai bahan penyusun pakan defisiensi lisin. Kekurangan asam amino menyebabkan penurunan efisiensi pemanfaatan pakan dan pertumbuhan. Tujuan penelitian ini adalah mengkaji penambahan lisin pada pakan buatan terhadap kecernaan protein, efisiensi pemanfaatan pakan, pertumbuhan, dan kelulushidupan benih lele Sangkuriang. Ikan uji yang digunakan dalam penelitian ini adalah lele Sangkuriang stadia pembesaran memiliki bobot rata-rata 6,48±0,22 g/ekor. Pakan uji yang digunakan dalam penelitian ini berupa pakan buatan berbentuk pellet dengan kandungan protein 31% yang ditambahkan lisin yaitu perlakuan A (0 %/kg pakan), B (0,5 %/kg pakan), C (1,0/kg pakan) dan D (1,5 %/kg pakan). Parameter yang diamati meliputi kecernaan protein (ADCp), efisiensi pemanfaatan pakan (EPP), rasio konversi pakan (FCR), protein efisiensi rasio (PER), laju pertumbuhan relatif (RGR), kelulushidupan (SR) dan kualitas air. Hasil penelitian menunjukkan bahwa penambahan lisin pada pakan dapat meningkatkan ADCp, EPP, FCR, PER, dan RGR. Parameter kualitas air selama penelitian menurut literatur masih layak untuk budidaya lele Sangkuriang. Dosis lisin 1,0 %/kg pakan merupakan dosis terbaik penambahan lisin pada pakan menghasilkan nilai ADCp, EPP, FCR, PER, dan RGR tertinggi sebesar 70,18±0,28, 71,02±0,15, 1,32±0,10, 3,06±0,13 dan 2,87±016%/hari.
