Abstract

Seleksi ikan mas berdasarkan marka ketahanan terhadap penyakit (MHC-II) telah menghasilkan ikan mas ?Mustika? sebagai ikan unggul tahan KHV (koi herpes virus). Adanya fenomena trade-off antar karakter menyebabkan laju pertumbuhan ikan mas Mustika relatif lebih rendah. Penelitian ini bertujuan memperbaiki performa ikan mas Mustika khususnya pada karakter pertumbuhan melalui seleksi. Pembentukan populasi F-1 hingga F-3 dilakukan menggunakan metode ?back-cross?, yaitu betina F-0><jantan F-1, betina F-1><jantan F-2 dan betina F-2><jantan F-3. Evaluasi pertumbuhan populasi ikan mas Mustika dari F-1, F-2, dan F-3 dilakukan pada karamba jaring apung selama tiga bulan. Pada evaluasi penampilan fenotipik populasi F-3 ikan mas Mustika pada kegiatan budidaya, digunakan populasi ikan mas Majalaya dari unit pembenihan rakyat (UPR) sebagai populasi kontrol eksternal. Hasil penelitian menunjukkan bahwa nilai respons seleksi karakter bobot ikan mas Mustika F-1, F-2, dan F-3 secara berturut-turut sebesar 7,29%; 34,51%; dan 8,12%; sehingga total respons seleksi yang diperoleh sebesar 49,72%. Pada kegiatan budidaya, populasi ikan mas Mustika mempunyai pertumbuhan, bobot individu panen, biomassa panen, konversi rasio pakan, dan produktivitas lebih baik dibandingkan dengan populasi ikan mas Majalaya dari UPR, masing-masing sebesar 5,99%; 11,60%; 13,32%; 39,59%; dan 11,19%.Marker-assisted selection (MAS) using MHC-II has successfully formed ?Mustika? as a resistant common carp strain against KHV. However, the trade-off among characters to form the KHV resistant carp strain has suppressed the growth trait of the species. This study was aimed to improve the growth character of Mustika common carp based on the selection of growth performance. The F-1, F-2, and F-3 populations were formed using the ?walk-back? method by crossing females of F-0 ><males of F-1, females of F-1 ><males of F-2, and females of F-2 ><males of F-3. Growth evaluation of each generation was based on body weight gain during the three months experiment. The growth evaluation of the F-3 Majalaya strain from a local breeder (UPR) was used as the external control. The results showed that the response to the selection of F-1, F-2, and F-3 of Mustika common carp were 7.29%, 34.51%, and 8.12%, respectively, with a total response to selection of 49.72%. In culture condition, the Mustika common carp has a better specific growth rate, individual weight, biomass at harvest, food conversion ratio, and productivity than the Majalaya common carp of 5.99%, 11.60%, 13.32%, 39.59%, and 11.19%, respectively.

Abstract

Ikan mas Mustika merupakan varietas unggul ikan mas hasil seleksi tahan penyakit Koi Herpes Virus (KHV). Secara laboratoris, uji tantang ikan mas Mustika dengan KHV menghasilkan sintasan lebih dari 90%. Namun demikian, performa ikan mas Mustika di lingkungan budidaya terkait pertumbuhan dan tingkat produktivitasnya belum banyak dikaji. Penelitian ini bertujuan mengevaluasi performa ikan mas Mustika sebagai varietas unggul tahan KHV di beberapa lokasi sentra budidaya. Penelitian dilakukan di kolam air deras (KAD) di Tanjungsiang, Subang; serta karamba jaring apung (KJA) di Waduk Jatiluhur, Purwakarta; Waduk Cirata, Cianjur; dan Waduk Darma, Kuningan. Sebagai pembanding digunakan ikan mas Majalaya yang berasal dari unit pembenihan rakyat (UPR) setempat. Penelitian dilakukan dengan tiga kali ulangan selama 90 hari. Hasil penelitian menunjukkan bahwa performa ikan mas lebih dipengaruhi oleh faktor lingkungan daripada faktor genetik, serta interaksi kedua faktor tersebut. Hasil penelitian juga menunjukkan bahwa kualitas perairan di Waduk Darma lebih rendah dibanding lokasi lainnya. Di lokasi tersebut, ikan mas Mustika mempunyai pertumbuhan, produktivitas, dan rasio konversi pakan sebesar 2,81%/hari; 13,42 kg/m2; dan 1,43 secara nyata lebih baik daripada varietas pembanding, sebesar 2,21%/hari; 8,16 kg/m2; dan 2,54. Di lokasi lainnya, performa ikan mas Mustika tidak berbeda nyata dengan varietas pembanding. Hal ini mengindikasikan bahwa ikan mas Mustika mempunyai toleransi yang lebih baik terhadap kondisi lingkungan perairan yang buruk, daripada varietas pembanding.Mustika is the newly produced superior variety of common carp strains resistant to Koi Herpes Virus (KHV). The challenge test of Mustika common carp against KHV resulted in a survival rate of more than 90%. However, the information on the growth and productivity of Mustika common carp in culture conditions is not yet available to supplement its superior resistance to KHV. This study was aimed to evaluate the performance of Mustika as a superior variety of common carp resistant to KHV resistance through multi-location tests which were in: running water ponds (KAD) in Tanjungsiang, Subang; floating net cages (KJA) in Jatiluhur Reservoir, Purwakarta; Cirata Reservoir, Cianjur; and Darma Reservoir, Kuningan. In all trial locations, Majalaya carp from the local hatchery (UPR) were used as the comparison population. The study was conducted for 90 days with three replications. The result showed that the performance of the carp was more affected by the environmental factor than both genetic and interaction of genetic >< environment factors. In Darma reservoir which has poorer water quality conditions, Mustika common carp had better growth, productivity and food conversion ratio of 2.81%/day, 13.42 kg/m2, and 1.43, respectively, compared to that of the comparison population of 2.21%/day, 8.16 kg/m2, and 2.54. Among the locations used in the multi-location test, the performances of Mustika common carp and the comparison population were not significantly different. These results indicate that Mustika common carp is more tolerant of being cultured in poorer water quality conditions

Abstract

One of the most popular techniques in mass production of all or nearly all male tilapia population is through sex reversal. However, cross mating of YY super male with regular brood-stock is gaining popularity and has been practiced by aqua-culturists. This study was conducted to evaluate the performance of 2 populations of sex reversed tilapia (sex reversed with dietary application of 17-α methyl testosterone, SRT-1, and sex reversed with dietary administration of imidazole, SRT-2) and 1 population of genetically male tilapia (GMT) derived from YY super male until the end of fingerling rearing period. Mixed sex tilapia (MST) derived from normal mating was used as the control population. The results showed that the daily growth rates of SRT-1, SRT-2, GMT, and MST were 0.12, 0.11, 0.20, and 0.07 g/day, with survival rates were 57.83%, 64.67%, 39.67%, and 68.78%, respectively. The GMT has higher harvest yield than the other populations; SRT-1 (+15.73%), SRT-2 (+6.37%), and MST (+20.82%).

Abstract

Timbulnya wabah penyakit KHV (Koi herpesvirus) pada budidaya ikan mas telah menurunkan produksi ikan mas nasional secara signifikan. Beberapa langkah dilakukan untuk mengatasi penyakit tersebut, salah satunya pembentukan ikan mas Rajadanu tahan KHV melalui seleksi. Dalam rangka memperoleh varietas unggul ikan mas tahan KHV pada tahun 2014 telah dilakukan pembentukan populasi F-3 melalui program selective breeding dengan metode walkback selection. Tujuan penelitian ini adalah menganalisis performa pertumbuhan ikan mas Rajadanu generasi ketiga hasil seleksi melalui uji skala lapang pada fase pembesaran, serta kegiatan uji tantang pada skala laboratorium. Benih F-3 merupakan hasil pemijahan F-1 betina dan F-2 jantan hasil seleksi positif MHC (Major Histocompatibility Complex), sedangkan kontrol berupa benih ikan mas Majalaya dari pembudidaya, masing-masing tiga ulangan. Uji tantang KHV dilakukan di akuarium berukuran 60 cm x 40 cm x 40 cm di hatchery ikan mas dengan suhu permissive 21°C melalui metode kohabitasi. Hasil penelitian menunjukkan bahwa populasi F-3 ikan mas Rajadanu hasil seleksi memiliki performa pertumbuhan relatif lebih baik 6,20% dibandingkan dengan kontrol pada karakter panjang total (18,14±4,90 cm), 5,80% lebih baik pada karakter panjang standar (14,76 ± 4,39 cm); 38,39% lebih baik pada karakter bobot rata-rata (393,98 ± 3,53 g); 16,83% pada karakter laju pertumbuhan spesifik (2,29 ± 0,04%); dan 3,80% pada karakter sintasan (49,13 ± 6,88%). Hasil uji tantang KHV menunjukkan sintasan populasi F-3 lebih tinggi (96,6 ± 3,3%) dibandingkan dengan kontrol (51,1 ± 8,3%).The outbreaks of KHV (Koi herpesvirus) disease in carp culture have significantly reduced Indonesia’s national carp production. Several strategies have been devised to combat the outbreaks including the development of KHV resistant carp varieties such as selective carp breeding program in 2014. The purpose of this study was to analyze the growth performance of the third generation (F-3) Rajadanu through field-scale test (grow out) and challenge test (laboratory-scale). The study was designed in a completely randomized design with two treatments (F-3 populations) and carp seed from the local small-scale fish farmers as control, each with three replicates. F-3 seed was produced from spawning between F-1 females and F-2 males which had a Major Histocompatibility Complex positive selection. The challenge test was carried out in the aquarium sized 60 cm x 40 cm x 40 cm at the hatchery with the permissive temperature of 21°C. The results showed that F-3 Rajadanu population had relatively higher total length (18.14 ± 4.90 cm) of 6.20%, standard length (14.76 ± 4.39 cm) of 5.80%, weight average (393.98 ± 3.53 g) of 38.39%, specific growth rate (2.29 ± 0.04%) of 16.83%, and survival rate (49.13 ± 6.88%) of 3.80% than that of control population. The result of the challenge test on KHV in the laboratory showed that F-3 population had higher survival rate (96.6 ± 3.3%) compared to that of control (51.1 ± 8.3%).

Abstract

Balai Penelitian Pemuliaan Ikan (BPPI) telah membentuk ikan mas Rajadanu tahan infeksi koi herpesvirus (KHV) dan tumbuh cepat melalui program seleksi. Ikan mas Rajadanu dihasilkan dari kegiatan seleksi bersamaan pada karakter ketahanan terhadap KHV dan pertumbuhan. Seleksi karakter ketahanan terhadap KHV dilakukan dengan menggunakan marka Cyca-DAB1*05 dan seleksi karakter pertumbuhan cepat dilakukan dengan metode seleksi individu. Penelitian ini bertujuan untuk mengevaluasi pewarisan marka Cyca-DAB1*05 dan keragaman genotipe ikan mas varietas Rajadanu tahan infeksi KHV dan tumbuh cepat generasi ketiga (F3). Sebanyak 44 individu ikan mas Rajadanu F3 digunakan pada penelitian ini. Evaluasi marka Cyca-DAB1*05 dilakukan dengan metode PCR menggunakan primer spesifik marka Cyca-DAB1*05. Analisis keragaman genotipe dilakukan menggunakan tiga lokus mikrosatelit (MFW6, MFW7, dan MFW9). Data alel mikrosatelit dianalisis menggunakan program Fstat dan Arlequin. Hasil penelitian menunjukkan bahwa semua individu pada populasi ikan mas Rajadanu F3 membawa marka Cyca-DAB1*05. Ikan mas Rajadanu F3 memiliki keragaman genotipe yang relatif rendah. Nilai rata-rata heterozigositas teramati (0,31) lebih kecil daripada rata-rata heterozigositas harapan (0,46). Nilai positif pada indeks fiksasi (0,32) menunjukkan status inbreeding pada populasi tersebut. Hasil penelitian ini dapat menjadi acuan, baik dalam kegiatan manajemen induk maupun dalam program seleksi selanjutnya dengan tujuan untuk mempertahankan keragaman genetik dan meminimasi tekanan inbreeding ikan mas Rajadanu tahan infeksi KHV dan tumbuh cepat.Research Institute for Fish Breeding (RIFB) has created Rajadanu common carp resistant to koi herpesvirus (KHV) infection and fast growth through selection program. Rajadanu common carp has been produced by independent culling selection on resistant to KHV and fast growth characters. Selection on resistant to KHV and fast growth character was conducted using Cyca-DAB1*05 marker and mass-selection method respectively. The aim of this study was to evaluate the inheritance of Cyca-DAB1*05 as a marker and the genotype variation of Rajadanu common carp resistant to KHV infection and fast growth. A total of 44 fish were used for this study. Evaluation of Cyca-DAB1*05 marker was conducted by PCR method using specific primer to Cyca-DAB1*05 marker. Analysis of genotype variation was conducted using three microsatellite loci (MFW6, MFW7, and MFW9). Microsatellite allele data was analyzed using Fstat and Arlequin software. The result showed that all of F3 Rajadanu common carp were positive carrying Cyca-DAB1*05 marker. Genetic variation of this population was relatively low. The average observed heterozygosity (Ho=0.31) was lower than the average expected heterozygosity (He=0.46). Positive value of fixation index (0.32) showed inbreeding status in this population. The result of this study can be use as reference for broodstock management and next selection program to maintain the genetic diversity and to minimize inbreeding depression level of Rajadanu common carp resistant to KHV infection and fast growth.

Abstract

Pembentukan ikan mas transgenik merupakan salah satu program penelitian di Balai Penelitian Pemuliaan Ikan, Sukamandi dalam rangka menghasilkan varietas unggul ikan mas tahan infeksi KHV (Koi herpesvirus). Pada tahun 2015 telah dilakukan pembentukan ikan mas transgenik tahan KHV generasi F-2. Penelitian ini bertujuan untuk mengevaluasi transmisi gen krt-GP11, ketahanan ikan mas transgenik F-2 terhadap infeksi KHV, keberadaan marka Cyca-DAB1*05 tahan KHV pada populasi ikan mas transgenik F-2. Ikan mas transgenik F-2 dihasilkan dengan memijahkan ikan mas transgenik F-1 jantan dengan betina non-transgenik. Pengujian transmisi transgen dan deteksi marka ketahanan KHV pada transgenik F-2 dilakukan dengan metode PCR menggunakan primer spesifik untuk transgen krt-GP11 dan gen Cyca-DAB1*05. Evaluasi ketahanan ikan mas transgenik F-2 terhadap infeksi KHV dilakukan dengan uji tantang secara kohabitasi. Hasil penelitian menunjukkan bahwa transmisi gen krt-GP11 pada keturunan F-2 memiliki persentase yang relatif rendah yaitu sebesar 0%-2%. Ikan mas transgenik F-2 memiliki ketahanan relatif baik terhadap KHV dengan sintasan uji tantang sebesar 90% dan tidak berbeda nyata dengan ikan mas pembanding atau non-transgenik (P>0,05). Tingginya pesentase keberadaan marka Cyca-DAB1*05 pada populasi transgenik berperan pada ketahanan ikan mas transgenik terhadap infeksi KHV.Creating of transgenic common carp is one of the breeding programs in Research Institute for Fish Breeding for producing a superior strain of common carp resistant to KHV(Koi herpesvirus). Since 2015, the creation of common carp transgenic has been conducted to produce F2 population resistant to KHV. This study was aimed to evaluate the transmission of krt-GP11 gen,the resistantce of F2 transgenic common carp against to KHV infection, and the existence of Cyca-DAB1*05 marker resistant to KHV in F2 transgenic population. F2 transgenic population has been produced by mating F1 transgenic male with non transgenic female. Transgene transmission and the existence of marker resistant to KHV in F2 transgenic population were evaluated by PCR method using specific primer to krt-GP11 gene and Cyca-DAB1*05 gene, respectively. The resistance of F2 transgenic population againstto KHV infection was evaluated by challenge test using cohabitation method. The result showed that transmission of krt-GP11 gene in F2transgenic population was relatively low with percentage of 0-2%. The resistance of F2 transgenic common carp against to KHV was relatively high with survival rate of 90% and was not significantly different from non transgenic (p>0.05). High percentage of transgenic population having Cyca-DAB1*05 marker had a role in resistance of transgenic population against KHV infection.

Abstract

Ikan mas (Cyprinus carpio) merupakan komoditas budidaya yang mudah beradaptasi dengan berbagai kondisi lingkungan. Penelitian ini bertujuan mempelajari pengaruh genotipe, lingkungan, dan interaksi antara genotipe dengan lingkungan terhadap stabilitas penampilan fenotipik ikan mas dalam kegiatan budidaya. Rancangan percobaan menggunakan rancangan faktorial 3 x 5 dengan lima ulangan. Lima strain ikan mas, yaitu Rajadanu, Sutisna, Majalaya, Wildan, dan Sinyonya dipelihara secara komunal di dalam tiga model wadah budidaya, yaitu kolam beton, kolam jaring, dan kolam tanah, selama 90 hari. Hasil penelitian menunjukkan bahwa penampilan fenotipik ikan mas dipengaruhi oleh genotipe, lingkungan dan interaksi kedua faktor tersebut. Strain Sutisna dan Wildan mempunyai nilai sintasan yang paling baik di semua lingkungan dibanding tiga strain lainnya. Strain Sutisna mempunyai pertumbuhan terbaik di kolam tanah sedangkan strain Wildan di kolam jaring. Hal ini menyebabkan kedua strain tersebut menghasilkan biomassa panen terbaik pada lingkungan yang berbeda. Hasil analisis stabilitas menunjukkan bahwa kelima strain ikan mas dalam penelitian ini relatif tidak stabil dan mempunyai respons yang berbeda jika dipelihara pada lingkungan yang berbeda. Strain Wildan dan Rajadanu merupakan strain ikan mas yang mempunyai respons terhadap perbedaan lingkungan paling tinggi. Strain dengan karakteristik tersebut akan mempunyai performa terbaik pada lokasi dan kondisi pemeliharan yang sesuai dengan kebutuhannya, tetapi mempunyai penampilan fenotipik yang rendah jika kondisi lingkungan budidayanya tidak sesuai. Strain Sutisna, Sinyonya, dan Majalaya merupakan strain ikan mas dengan daya responsi terhadap lingkungan lebih rendah. Karakteristik ini menyebabkan penampilan fenotipik ketiga strain tersebut relatif stabil pada semua lokasi dan kondisi budidaya, meskipun tidak bisa mencapai hasil yang maksimal.Common carp (Cyprinus carpio) is known as fish species highly adaptable to various environmental conditions. This study aimed to evaluate the effect of genotype, environment, and their interaction in phenotypic performance stability of common carp. The experimental design used a 3 x 5 factorial design with five repetitions. Five strains of common carp, namely Rajadanu, Sutisna, Majalaya, Wildan, and Sinyonya were stocked communally for 90 days in three culture systems: concrete pond, net cage pond, and earthen pond. The result showed that the phenotypic performance of common carp was influenced by genotype, environment, and their interaction. Sutisna and Wildan strains have a higher survival rate compared to other strains in all culture systems. Sutisna and Wildan strains have the best growth performance in the earthen pond and net cage pond, respectively. Both strains also have the highest biomass production at harvest in all culture systems. Based on the stability performance analysis, Wildan and Rajadanu have the highest response to the different environmental conditions. Strains with this characteristic perform best in different locations or culture systems as long as the environmental conditions are suitable. However, these fish will likely perform poor in the unsuitable culture environment. Sutisna, Sinyonya, and Majalaya are carp strains with lower responsiveness to environmental change. Such characteristic causes the phenotypic performance of these three strains cannot achieve the maximum results, yet it is relatively stable in all locations.
