Abstract

Dip treatment on pearl oysters (Pinctada maxima) was conducted in different concentrations of saline water to eliminate boring polychaetes. Results shows that polychaetes leave the oysters which treated on saline water at 0 ppt, 45 ppt, and 60 ppt as long as 15 minutes each. It also shows that the oysters got high survival rate 7 days after the treatment. Key words: Pearl oyster, Pinctada maxima, polychaetes, salt, dipping, survival rate

Abstract

This study was done to discover the effect of addition of chromosome number on phenotype F1 hybrid of females kohaku (white-red) and sanke (white-red-black) koi with males white and red koi. The white and red males koi were the F1 of gynogenesis. Spawning of koi was done by hormonal (ovaprim 0,5 ml/kg body weight) and fertilization was done artificially. Triploidization was done by heat shock at 40°C during 1,0-1,5 minutes after 2-3 minute from egg fertilization. Colour analysis was done on 4 months old fish. Triplodization was succeeding on 86,67%.  Addition of chromosome number on koi due to triploidization was suppressed the percentage of koi with combination color (kohaku, shiro-bekko, hi-utsuri, and sanke). It was seen on hybridization of sanke vs white koi as much as 5,55%, while on sanke vs red koi reached 45,02%. Hybridization of kohaku vs white koi as well as kohaku vs red koi produced higher percentages of kohaku compared to kohaku vs kohaku. Key words: Phenotype, diploid, triploid, koi fish, hybrid, chromosome   Abstrak Studi ini dilakukan untuk mengetahui pengaruh penambahan jumlah set kromosom terhadap fenotipe keturunan persilangan ikan koi kohaku (putih-merah) dan sanke (putih-merah-hitam) betina dengan jantan putih dan merah. Ikan koi jantan putih dan merah merupakan hasil ginogenesis generasi pertama. Pemijahan ikan koi dilakukan dengan rangsangan hormonal ovaprim 0,5 ml/kg induk dengan sistim pembuahan buatan. Triploidisasi dilakukan dengan memberikan kejutan panas 400C selama 1,0-1,5 menit pada saat 2,0-3,0 menit setelah pembuahan telur. Analisis warna dilakukan setelah ikan berumur 4 bulan. Tingkat keberhasilan triploidisasi yang diperoleh cukup tinggi, yaitu sebesar 86,67%. Penambahan jumlah set kromosom ikan koi akibat triploidisasi menurunkan persentase ikan koi yang berwarna kombinasi (putih-merah, putih-hitam, merah-hitam dan putih-merah-hitam) sebesar 5,55% untuk persilangan sanke vs putih, dan 45,02% untuk persilangan sanke vs merah. Tingginya penurunan koi warna kombinasi diduga disebabkan adanya dominansi warna tertentu, misalnya dominansi warna hitam yang persentasenya meningkat sebesar 31,7% pada persilangan sanke vs merah. Pada persilangan kohaku dengan koi putih dan dengan koi merah, persentase kohaku lebih besar daripada perkawinan normal kohaku yang diperoleh pada tahap pertama. Persentase kohaku dari perkawinan normal kohaku hanya sebesar 18,6%, sedangkan kohaku vs putih atau dengan merah adalah sekitar 27% untuk triploidisasi dan 33% untuk persilangan  normal. Tingkat kelangsungan hidup ikan normal lebih besar daripada ikan hasil triploidisasi, kecuali persilangan sanke vs putih. Kata kunci : Fenotipe, diploid, triploid, ikan koi, hibrid dan kromosom

Abstract

This study was aimed to identify fauna parasite of juvenile tiger grouper (Epinephelus fuscoguttatus) on the two locations of floating net at Floating Net Sea Farming Center, Pulau Seribu Jakarta. A total of five tiger grouper fry from each location, checked every two weeks during the nursery period in August-September 2008 and June-August 2009. Parasites of young tiger grouper found were protozoa (Trichodina and myxosporea), monogenea Diplectanum, metaserkaria digenea, and isopods Alitropus. Diplectanum infestation was dominant with prevalence reached 100% and the average intensity of 2,87-72,8. Fish nursed in the Perairan Pulau Semak Daun was more susceptible compared to the fish nursed in Pulau Karang Congkak. Keywords: tiger grouper, parasite, infestation, Seribu Island. ABSTRAKPenelitian ini bertujuan untuk mengidentifikasi penyakit yang menyerang benih kerapu macan pada masa pendederan dalam karamba jaring apung di dua lokasi Karamba Jaring Apung Balai Sea Farming, Kepulauan Seribu, yaitu di Perairan Pulau Semak Daun dan Perairan Pulau Karang Congkak. Sebanyak 5 ekor benih kerapu macan dari masing-masing lokasi, diperiksa setiap minggu selama dua periode pendederan pada bulan Agustus-September 2008 dan bulan Juni-Agustus 2009. Fauna parasit benih kerapu macan pada masa pendederan dalam jaring apung tersebut meliputi protozoa (Trichodina dan myxosporea), monogenea Diplectanum, metaserkaria digenea, dan isopoda Alitropus. Diplectanum merupakan parasit yang mendominasi dengan prevalensi mencapai 100% dan intensitas rerata 2.87–72,8.

Abstract

This experiment was conducted to study phenotype of F1 koi that were obtained from hybridization. Females koi that was used for this experiment were white-red koi, red-black koi, and white-black koi; whereas males used white-red koi, red-black koi, white-black koi and white-red-black. Spawning for hybridization was done using hormonal stimulation with 0.5 ml ovaprim/kg body weight, and fertilization were artificially performed. Analysis on body coloration was carried out at three months old fish. Normal F1 of white-red koi as well red-black koi produced three kind of koi, while white-black koi produced seven kind of koi, i.e. white koi, red koi, black koi, white-red koi, white-black koi, red-black koi and white-red-black koi. Hybridization of those koi produced seven kind of koi such as normal F1 of white-black koi.

Ikan koi betina yang dipakai adalah ikan koi putih-merah, merah-hitam dan putih-hitam, sedangkan jantannya adalah putih-merah, merah-hitam, putih-hitam dan putih-merah-hitam. Ikan-ikan tersebut diperoleh dari teknik ginogenesis. Pemijahan untuk persilangan antar jenis ikan koi dilakukan dengan rangsangan hormonal ovaprim 0,5 ml/kg, dan pembuahan dilakukan secara buatan. Analisis warna pada ikan dilakukan setelah ikan berumur 3 bulan. Hasil penelitian menunjukkan bahwa perkawinan normal koi putih-merah maupun merah hitam masing-masing menghasilkan tiga tipe warna (dua warna polos dan satu warna kombinasi) sedangkan koi putih-hitam menghasilkan tujuh tipe warna. Perkawinan silang antara ketiga ikan tersebut menghasilkan tujuh warna yang sama dengan keturunan normal merah-hitam, yaitu putih, merah, hitam, putih-merah, putih-hitam, merah-hitam dan putih-merah-hitam.

Abstract

This experiment was conducted to study phenotype of F1 koi that obtained from gynogenesis at the Laboratory of Fish Genetic and Breeding, Department of Aquaculture, Faculty of Fisheries and Marine Sciences, Bogor Agricultural University (IPB). Females koi used for this experiment were kohaku (white-red), hi-utsuri (red-black), and shiro-bekko (white-black); whereas males used kohaku, hi-utsuri, and shiro-bekko. Analysis on body coloration of fish was carried out at three months old. Results showed that gynogenesis from kohaku produced three types of koi, those were white koi, red koi and kohaku, and hi-utsuri produced red koi, black koi and hi-utsuri. Meanwhile, shiro-bekko by gynogenetic technique produce seven types of koi; those were white, red, black, kohaku, shiro-bekko, hi-utsuri and sanke (white-red-black koi). Survival rate of gynogenetic koi was lower then normal might be due to inbreeding stress.

Hasil penelitian menunjukkan bahwa ginogenesis pada ikan kohaku menghasilkan tiga jenis ikan koi, yaitu koi putih, koi merah dan kohaku; pada ikan hi-utsuri dihasilkan ikan koi merah, koi hitam dan hi-utsuri. Sementara itu, teknik ginogenesis untuk ikan koi putih-hitam dihasilkan tujuh macam jenis ikan koi, yaitu koi putih, koi merah, koi hitam, kohaku, hi-utsuri, siro-bekko dan sanke (putih-merah-hitam).

Penicillin G and streptomycin sulphate were administered for 18 days of rearing of sand goby larvae. 7wo-days larvae (3,37-3,41 mm) were reared in 160 1 aerated water at stocking density of 50 fish/1.  Until 17 days of rearing period, the larvae were fed plankton (50-300 gm) at stocking density of 20-30 individual/mi, and at day 13-I8, were fed Artemia sp. (1-2 individual/ml).  During first seven days, penicillin G and streptomycin sulphate (1.000 IU/1 and 10 mg/1, respectively) were applied daily, and there after once every three days.  The fry which reared in media containing antibiotics exhibited higher survival rate (28,09%, compared to 3,3 1 %), than the control, whereas their growth was similar (1,09-1,53 mm).
