Abstract

Metamorfosis pada larva teripang diikuti dengan perubahan tingkah lakunya. Stadia auricularia bersifat planktonic sedangkan stadia akhir doliolaria dan awal pentactula bersifat bentik dan memerlukan substrat untuk menempel. Perubahan ini merupakan saat kritis dalam pembenihan teripang sehingga substrat yang sesuai perlu diberikan pada media pemeliharaan larva. Penelitian ini bertujuan untuk mengetahui kesuakaan penempelan larva teripang putih (H. scabra) pada substrat asbes, kasa plastik dan kaca. Penghitungan densitas larva yang menempel pada tiap substrat dilakukan sejak larva mulai menempel pada hari ke-25 hingga larva mencapai stadia juvenil-umur 35 hari. Hasil penelitian menunjukkan bahwa substrat memberikan pengaruh yang berbeda nyata (P>0.05) terhadap jumlah larva yang menempel. Larva lebih banyak menempel pada substrat asbes (rata-rata 425,28 individu.m2 dengan kelulushidupan 9,96 % tetapi substrat kaca paling sedikit ditempeli larva (85,18 individu.m2 dengan kelulushidupan 3,98%). Perbedaan jumlah larva yang menempel pada perlakuan substrat diduga berkaitan dengan kekasaran permukaan substrat.Kata kunci: larva teripang putih; penempelen; substrat??The metamorphoses of seacucumber larvae indicate changing in their behaviour. Auricularia stage is planktonic but late doliolaria and early pentactula are benthic and need suitable substrate. It is a critical period in development and culture of seacucumber larvae since the biggest mortality happened during metamorphosis and settlement therefore the suitable substrata need to be provided. The aims of the experiment was to determine larvae's preference on substrate made of asbestos, plastic screen and glass. Density of larvae settled on the substare were counted on day 25 up to juvenile stage of 35 days old. The results showed that the treatment gave significant differences on larvae settlement on the substrate. The larvae found attached on asbestos was highest (425,28 ind.m2 and survival rate 9.96 %) and lowest number larvae settled on glass (85,18 ind.m2 and survival rate 3,98 %). It seemed due to difference roughness of surface.Keywords: larvae seacucurnber; settlement; substrats

Abstract

In fish grouper escpecially humpback grouper culture, seed and broodstock quality and availability determine the production success. Main supply of wild broodstock still dominates grouper hatchery activities, therefore, the exploitation of the wild broodstock is very high. Efforts to use the supply of cultured broodstock through selection and breeding processes will greatly determine their culture success. The purpose of this experiment was to get seeds from the cross breeding between F-2 and F-0. The research used two (2) concrete tanks with volume of 75 m3 each. Each tank was filled with 20  fishes consisting of 10 fishes of F-2 and 10 fishes of F-0. The experiment was conducted the Institute of Mariculture Research and Development, Gondol, Bali. The result showed a good gonadal development and natural spawning of cross breeding between F-2 and F-0. Total number of eggs (1.320.000) was found the highest in May in tank A, while the highest fertilized eggs of 385.000 were found in June.  The SSCP analyses showed no difference in genetic characters of broodstock from cross-breeding between the female parent F-2 and F-0 male parent.

Abstract

Genetic variations of marble groupers, Epinephelus polypekhadion were evaluated to know genetic performance of fish to support fish seed production. Fifty fish samples from three locations i.e. West Nusa Tenggara, South Sulawesi and East Java were collected for analysis. Genetic analysis has been examined through allozyme electrophoresis by using 11 enzymes (ADH, GPI, SDH, IDH, LDH, ME, PGM, 6PGD, MPI, SP, EST). The result showed that 16 loci were detected, and three of them were polymorphism enzymes namely Isocitric dehydrogenase (IDH*), Glucose Phosphate Isomerase (GPI-1*) and Esterase (EST-2*). One locus (EST-2) was polymorphic in the East Java and West Nusa Tenggara populations and three loci (EST-2, GPI-1 and IDH) were polymorphic in the South Sulawesi population. The heterozygosity ranged from 0.007 to 0.034. Rogers genetic distance between population pairs were ranged from 0.005 to 0.012 (average = 0.009). Differences between genetic populations were significant (P<0.05). East Java and West Nusa Tenggara populations have same gene pool.

Abstract

Samples of yellowfin tuna (Thunnus albacares) were taken from three locations Bali, North Sulawesi and North Maluku. The glucose-6-phosphate isomerase (GPI) was analyzed from liver using allozyme electrophoresis method. Polymorphism of GPI enzyme was observed and four alleles (A, B ,C, D) were found in Bali population, three alleles (A,B,C) were found in North Maluku and North Sulawesi populations. Heterozygosity values, from Bali, North Maluku and North Sulawesi were 0.419; 0.417; 0.143 respectively. Genetic distance between North Sulawesi and North Maluku were 0.029, and with Bali population was 0.353. These results indicated that North Maluku and North Sulawesi population were not separate by geographic barrier, therefore genetic distance of both populations was closed. However, those populations were genetically separated to the Bali population might be due to major hydrological barrier.

Abstract

Variasi mitokondria DNA pada ikan tuna sirip kuning, Thunnus albacares menggunakan analisis RFLP (restriction fragment length polymorphism) dapat menyediakan data yang akurat dan memberikan bukti tentang profil pemijahan ikan tuna dalam bak terkontrol. Genotipe mt-DNA yang berasal dari induk dibandingkan dengan genotipe yang ada pada telur untuk memonitor dan mengetahui profil dari pemijahan ikan tuna dalam bak terkontrol. Telur dikumpulkan setiap pemijahan dari tahun 2004-2006. Profil pemijahan dari induk betina diamati dari jumlah genotipe yang ditemukan pada telur. Hasil dari penelitian ini adalah 49 induk yang dianalisis ditemukan 42 genotipe, 6 genotipe yang teramati ditemukan pada telur dan 4 diantaranya memiliki genotipe tunggal sedangkan satu genotipe (DABEA) dimiliki oleh dua induk. Prakiraan panjang cagak dan bobot induk pada saat memijah adalah 82,2-164 cm and 9,183-28,142 kg. Genotipe yang sama ditemukan hampir setiap hari pada saat sampling selama setahun. Hasil ini mengindikasikan bahwa ikan tuna sirip kuning dapat bertelur sepanjang tahun tergantung kepada suhu air dan kondisi pakan.Study of mitochondrial (mt-DNA) variations of yellowfin tuna, Thunnus albacares using (RFLP) restriction fragment length polymorphisms can provide evidence of spawning profile of the species in captivity. Mt-DNA genotypes of broodstock were compared with their eggs in order to monitor spawning profile. Spawned eggs were collected on every spawning from 2004 to 2006. The spawning profiles of these females were determined from the genotypes of the eggs. The result showed that from 49  broodstock individuals, 42 genotypes were observed, in which 6 genotypes were observed in their eggs and 4 of them established a single female’s identity and one type (DABEA) was shared by two females. Fork length and weight of broodstock female when spawning were ranging from 82.2–164 cm and 9.183-28.142 kg. The same genotypes were observed in almost every sampling session for one year period. The results indicate that the females are able to spawn at any time depending on optimum water temperature and food availability.

Abstract

Upaya seleksi pada benih udang windu dengan mengutamakan karakter toleran terhadap WSSV menjadi prioritas, agar diperoleh calon induk udang windu dengan karakter genotip yang lebih baik. Tujuan riset adalah mendapatkan profil genotip benih udang windu hasil seleksi dengan karakter toleran terhadap WSSV. Metode untuk mendapatkan benih udang terseleksi, diawali melalui pembenihan dengan menggunakan induk udang windu berasal dari alam (F-0), mengaplikasikan probiotik dalam pemeliharaan larva, biosecurity dan pemantauan infeksi virus. Uji tantang virus WSSV (LD-50) dilakukan dengan perendaman dan pemberian pakan (oral). Hasil yang diperoleh menunjukkan bahwa benih udang F-1 memberikan keragaan fenotip yang bervariasi (ukuran besar, sedang dan kecil). Benih udang F-1 berukuran besar, diperoleh 20,18%-35,04%, sedangkan ukuran sedang dan kecil masing-masing sebesar 43,28%0,49% dan 9,47%-21,66% dari populasi benih udang yang dihasilkan. Keragaan genotip benih F-1 menunjukkan keragaman genetik yang berbeda. Nilai heterozigositas pada benih F-1 pada udang dengan ukuran besar adalah 0,51, sedangkan ukuran sedang dan kecil masing-masing 0,45 dan 0,22. Hasil uji tantang dengan WSSV melalui perendaman maupun pemberian pakan (oral) terlihat ada perbedaan toleransi pada benih udang F-1. Dengan LD-50 menunjukkan bahwa pada udang ukuran kecil, mortalitas terjadi dalam waktu 48 jam (oral). Sementara, pada udang ukuran besar dan sedang, mengalami mortalitas dalam waktu 72 jam. Profil genotip benih udang yang toleran terhadap infeksi WSSV mengekspresikan pola gen yang lebih bervariasi
