“…Dewi et al (2017) said performance escalation of the selection result fish was expected to be caused by the improving genes inside of its body organs which controlled the growth and the feed conversion rate from the fish itself. Parenrengi et al (2013) showed that the RNA/DNA ratio value which had been gained from the selection results giant tiger prawn at the higher growth character compared to the control shrimp. Although it is still precisely unknown which genes that was responsible for the growth of the giant tiger prawn, the selection results were expected for possessing higher capability at forming the protein synthesis which is related to the increased growth rate of the giant tiger prawn itself.…”

Perkasa pangasiid (Pangasianodon hypophthalmus) is a superior catfish selected by the family that has been released by the Minister of Marine and Fisheries as aquaculture fish which has a selection response of 38.86 %. Genetic quality improvement to accelerate growth can be done through selection activities. The performance test of the Siamese catfish from the selection (Perkasa strain) compared to the non-selection strain (local strain) originating from the farmer. The purpose of this study was to compare the productivity of selection and non-selection Siamese catfish cultivation maintained in a net pond. The initial seeds of the test fish were 3.76 g to 3.79 g with a total length of 2 inches to 3 inches kept in a net pond measuring 3 × 5 × 1.25 m. The water level was around 100 cm with a density of 175 fish/net. Maintenance was carried out for six months. Test parameters observed included: weight gain, specific growth rate, biomass harvest, productivity and cost of production. The results showed that Siamese catfish which were selected for six months of maintenance had a final weight of 698.40 ± 164.54 g and non-selection strains of 595.77 ± 103.41 g. As well as having a higher specific growth rate (3.51 %), higher harvest biomass (11.44 %), and higher productivity (18.71 %) than non-selection Siamese catfish. Based on the bioeconomic analysis, the selection of enlarged Siamese catfish cultivation can reduce production costs up to Rp 390 /kg. The use of Perkasa Pangasiid superior seeds can increase harvest biomass higher than the non-selection seeds.

This study aimed to evaluate the growth of stunted elver Anguilla bicolor from three different periods of stunting process. Prior to experiment, the stunting process of elver was carried out by limiting the feeding rate at 2% of the fish biomass and temperature media with 24 oC for 2, 4, and 6 months period. The study used a completely randomized design with three different sources of stunted elvers (i.e., A = 2 months; B = 4 months; C = 6 months) as treatments with three replications. Measurement of RNA:DNA ratio, protein content, profile blood description and elver otolith growth was carried out at the beginning and end of rearing process. Post-stunting elvers were reared on artificial media designed according to elver habitat and controlled. Elver was stocked with 15 individuals in the artificial semi-natural media with a temperature of 28 oC and fed with 1 kg media-1 day-1 tubifex worm for three months. The results showed that the compensatory growth of stunted elvers increased two to three times with 100% of survival rate after three months of rearing process. Stunting has a significant effect on treatment B, indicated by the value of weight specific growth rates, RNA : DNA ratio, protein content, blood glucose levels and otolith growth of elvers. This study revealed that the growth performance of stunted elver reared in semi-natural media for four months is better than other treatments.

“…Panjang dan bobot ikan patin siam memiliki korelasi yang erat (R>0,5) dengan rasio RNA/DNA. Menurut Parenrengi et al (2013), pertambahan bobot memiliki hubungan erat dengan meningkatnya rasio RNA/DNA. Haryanti et al (2006) melaporkan bahwa performa (nilai morfologi) larva udang windu memiliki korelasi dengan rasio RNA/ DNA, dan ada indikasi bahwa semakin baik nilai morfologi larva semakin tinggi nilai rasio RNA/DNA udang windu tersebut.…”

“…Haryanti et al (2006) melaporkan bahwa performa (nilai morfologi) larva udang windu memiliki korelasi dengan rasio RNA/ DNA, dan ada indikasi bahwa semakin baik nilai morfologi larva semakin tinggi nilai rasio RNA/DNA udang windu tersebut. Penelitian yang dilakukan oleh Parenrengi et al (2013) menunjukkan bahwa nilai rasio RNA/DNA yang didapatkan pada udang windu hasil seleksi pada karakter pertumbuhan lebih tinggi dibandingkan dengan udang kontrol. Walaupun belum diketahui secara pasti gen yang berperan dalam pertumbuhan udang windu, hasil seleksi diduga memiliki kemampuan yang lebih tinggi dalam pembentukan sintesis protein yang terkait dengan peningkatan laju pertumbuhan udang windu.…”

ABSTRAKPeningkatan produksi ikan lele perlu didukung oleh ketersediaan benih berkualitas baik. Pada penelitian ini dilakukan pengujian penggunaan benih unggul ikan lele hasil seleksi (strain Mutiara) dengan tujuan untuk mendapatkan informasi mengenai performa hasil seleksi terhadap pertumbuhan, sintasan, konversi pakan, rasio RNA/DNA, dan nilai bioekonominya. Pengujian dilakukan di sentra budidaya ikan lele di Kabupaten Sleman. Hasil pengujian pertumbuhan pada kolam tembok berukuran 12,5 m 2 menunjukkan bahwa strain Mutiara menunjukkan bobot akhir, sintasan, dan biomassa panen yang lebih tinggi (P<0,1) dibandingkan strain lokal. Strain Mutiara lebih efisien dalam memanfaatkan pakan dibandingkan strain lokal yang ditunjukkan dengan nilai FCR yang lebih rendah. Pertumbuhan strain Mutiara yang lebih cepat didukung oleh peningkatan rasio RNA/DNA yang lebih tinggi dibandingkan strain lokal. Berdasarkan analisis nilai bioekonomi, biaya yang dikeluarkan untuk menghasilkan 1 kg ikan lele strain Mutiara lebih murah (Rp 12.576,-) dibandingkan strain lokal (Rp 15.105,-). Nilai BCR pada budidaya ikan lele strain Mutiara (1,3) lebih tinggi dibandingkan strain lokal (1,1), yang menunjukkan bahwa budidaya ikan lele strain Mutiara lebih menguntungkan dibandingkan strain lokal. Keuntungan yang diperoleh pada budidaya ikan lele strain Mutiara (31,2) mencapai tiga kali lebih tinggi dibandingkan strain lokal (9,9), berdasarkan nilai pengembalian modal (ROI). Masa pengembalian modal (PP) pada budidaya ikan lele strain Mutiara (3,2 siklus) adalah 3 kali lebih singkat daripada strain lokal (9,9 siklus). (IDR 12,576) was lower than that of local strain (IDR 15,105). The BCR value for Mutiara strain farming (1.3) was higher than that of local strain (1.1), indicated that Mutiara strain farming was more beneficial than that of local strain. The value of return of investment (ROI) for Mutiara strain (31.2) was three times higher than that of local strain (9.9). The payback period (PP) on the Mutiara strain farming (3.2 cycles) was shorter than that of local strain (9.9 cycles). KATA KUNCI:
