“…The synthetic population was formed by crossing Chitralada, Philippines, NIFI, and Singapore tilapia strains and then the best 10% of the population was taken. The results obtained statistically showed that as a result of the selection process there was a 25% decrease in diversity from F-0 to F-4 [4].…”

“…Genetic inheritance is characterized by slow growth, faster gonadal maturation and high mortality due to weak disease and environmental resistance. Alternatives to overcome this problem can be done by breeding, one of which is hybridization [4] There are four types of tilapia based on origin and/or strain used in this study, including nilasa (Cangkringan), red nifi (Sukabumi), pandu (Janti) and tilapia from Sukamandi. Nilasa (Nila strain satria) is a type of red tilapia as a result of individual selection from the Aquaculture Technology Development Center DIY, Cangkringan, which was introduced in 2012 based on the Decree of the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia Number KEP.47/MEN/2012.…”

Breeding red tilapia is one of the solutions to produce the best tillers based on their growth. The strains used are Cangkringan, Janti, Sukabumi, and Sukamandi. Each strain was spawned to produce 16 crosses, both inbreeding and outbreeding. This study aims to determine the results of crosses that have the best growth based on survival rate, growth, and feed conversion ratio. This research lasted for 90 days from 1 September 2022 to 30 March 2023 at the Aquaculture Technology Development Center DIY, Cangkringan, Sleman. Spawning was done by hybridization. The study was conducted in a completely randomized design using a 1×1 meter pond. Feed is given 2 times a day with a 10% biomass ratio. This study was conducted by two nurseries. Observation of the weight and length of individuals was carried out by sampling, as well as water quality every two weeks. Survival rate, growth, and feed conversion ratio data were analyzed by analysis of variance and tested by Tukey’s Multiple Comparison Test. Water qualities were tested descriptively. The results obtained: survival rate ranged from 73-98%, specific weight 1.35-6.451%, and feed conversion ratio 1.11-1.68. From the results of the research, it can be concluded that the Janti-Sukamandi cross breeding has the best quality for the first nursery and the Cangkringan-Sukabumi cross breeding has the best quality for the second nursery. The water quality meets the requirements for cultivating red tilapia.

“…Tilapia became an export commodity in place of red sea bream Chrysophrys major marine fish, favored by the world's consumers because it has an attractive meat color, delicious taste and does not have thorns between muskulars.

Tilapia fish is much in demand because it has several advantages such as its distinctive taste that makes tilapia delicious after being processed in any way. Tilapia has the potential to be used as an export commodity in the form of fish fillets and the price is relatively cheap. The climate situation and the extent of freshwater fishing land are contributing factors in the development of tilapia cultivation in Indonesia. One of the efforts to increase efficiency and productivity in cultivation is fish spawning activities. Spawning activities are important for producing seeds or larvae. Female fish are 300 to 400 g and for males, 400 to 500 g, aged 5 months. Tilapia can colonize weighing 250 g and age 4 to 6 months, meaning the parent used in this study has been following the required. The maintained parent is a healthy, unformed, and complete morphological parent (SNI 01-61412009). The purpose of this study is to improve the quality of Tilapia fish seeds produced by the Mina Ayu Group of Tabanan Regency of Bali Province by a selective breeding method. Male and female tilapia broods are kept separately in hapa measuring 5x5x1m. In shelters, for the acceleration of gonad maturation before the fish are stocked in the spawning pond. The feeding given during maintenance is 2 to 3%. Individual selection methods can improve the quality and survival rate of tilapia fish larvae. The absolute length increased 1.5 cm and weight increased 0.950 mg/day with a survival rate of 80% to 90%.

“…Salah satu upaya yang dapat dilakukan untuk meningkatkan kualitas genetik pada karakter yang diinginkan adalah melalui program pemuliaan dengan metode seleksi. Menurut Nugroho et al (2014), kegiatan seleksi merupakan upa-ya untuk mempersempit atau menurunkan variasi sifat tertentu agar lebih stabil dengan memanfaatkan pengaruh silang dalam. Kegiatan seleksi pada ikan nila merah di Balai Riset Pemuliaan Ikan telah dilakukan dalam rangka pembentukan ikan nila merah toleran salinitas tinggi.…”

Genetic quality improvement can be done through breeding programs. The indicator of success in the selection is the improvement of the character of production. Larval production and growth of NIFI of F1generation red tilapia seeds in the selection and its control parents were evaluated in this study. The research was conducted at the Fish Breeding Research Center for four months. Spawning was carried out on freshwater ponds of cage with size of 1 x 1 m. Tilapia brood stock were stocked with male to female ratio of 1: 1. The larvae rearing were conducted in the cage with size 2x2x1 m3 and stocking density 125 m-2. Pellets with a protein content of 38-40% are given to ad libitum larvae three times a day for first month, and then feeding rate was given 15-20% daily from biomass. Seed production, growth, specific growth rate, and survival rate were observed. The results of the experiment show a difference between fish selected and control. Seed production of selection reached 540 ± 114 and controls 508 ± 142. The growth performance of selected red tilapia juvenile showed higher compared with the control. The mean length of selected population reached 6.33 ± 0.43 cm , weight gain 6.60 ± 0.52 g, specific growth rate 7.33 ± 0% g days-1 and survival rate 81.50 ± 4.46% were respectively and the control population 5.76 ± 0.52 cm ; 4,90 ± 0.58 g; 4.50 ± 0.35% g days-1; and 74.85 ± 3.26%. These values indicate that the growth of red tilapia juvenile NIFI F1 generation was increased 25.76%.AbstrakSalah satu upaya yang dapat dilakukan untuk meningkatkan kualitas genetik yaitu melalui program pemuliaan. Per-baikan karakter reproduksi dan pertumbuhan dapat digunakan sebagai indikator keberhasilan seleksi. Penelitian ini bertujuan untuk mengevaluasi produksi larva dan pertumbuhan benih ikan nila merah NIFI F1 dari induk seleksi dan kontrol. Kegiatan dilaksanakan selama empat bulan di Balai Riset Pemuliaan Ikan. Pemijahan dilakukan di kolam air tawar pada hapa 1 m x1 m. Perbandingan induk ikan nila jantan dan betina 1:1. Larva yang sudah dipanen dimasukkan pada hapa pendederan ukuran 2x2x1 m3 dengan padat tebar 125 ekor m-2 . Selama pendederan , larva diberi pakan (protein 38-42%) secara ad libitum tiga kali sehari pada bulan pertama dan selanjutnya diberi pakan dua kali sehari 15-20% dari biomassa. Pakan yang diberikan selama pendederan mempunyai protein berkisar 38-42%. Parameter yang diamati meliputi produksi larva, pertumbuhan, laju pertumbuhan spesifik, dan sintasan. Hasil penelitian menunjukkan produksi larva ikan nila merah seleksi yaitu 540±114 ekor dan kontrol 508±142 ekor. Performa pertumbuhan benih ikan nila merah seleksi menunjukkan hasil yang lebih tinggi dibanding kontrol dengan nilai pertumbuhan panjang 6,33 ±0,43cm, pertumbuhan bobot 6,60±0,52 g, laju pertumbuhan spesifik 7,33±0% g hari-1 serta sintasan 81,50±4,46%, se-dangkan populasi kontrol masing-masing 5,76±0,52 cm; 4,90±0,58 g; 4,50±0,35% g hari-1; dan 74,85±3,26%. Nilai ini menunjukkan bahwa ada peningkatan pertumbuhan sebesar 25,76% pada benih ikan nila merah NIFI F1.
