Abstract

This study was conducted to examine activity of medaka (Oryzias latipes) â-actin promoter (mBP) in common carp(Cyprinus carpio) as the first step towards development of common carp transgenic in country. Gene constructpmBP-hrGFP that consists of mBA promoter and humanized Renilla reniformis green fluorescent protein gene(hrGFP) was injected into cytoplasm of one cell stage of common carp by using microinjector. PmBP-hrGFPconcentration used for microinjection was 50 μg/mL aquabides. Parameters observed were survival rate of embryo(SRe), hatching rate (HR) and expression of hrGFP gene. SRe was calculated before eggs hacthed, while hatchingrate (HR) was after all of eggs hatched. The activity of mBA promoter was analyzed by observation of hrGFP genetransient expression using a fluorescence microscope. The results of experiment showed that SRe (87,5%) andHR (79.2%) of control was respectevily higher than that of injected treatment (75.0% & 61.7%). Expression of hrGFPwas observed firstly at blastula (12 hours after fertilization) to 1-day-old larval stages (24 hours after hatching)with higher gene expression at blastula to late gastrula stages. Percentage of micronjected larvae expressinghrGFP at 6 hours after hatching reached 71.6 ± 6.7%. Conclusion was that mBA promoter could drove hrGFPexpression in common carp, hence it can be used to produce common carp transgenic by changing hrGFP withgenes correlated with important traits in aquaculture.

Abstract

Deoxyribonucleic acid (DNA) vaccine has recently been developed as an alternative vaccine against virus infection.This study was the first step of DNA vaccine development to protect cyprinids including common carp (Cyprinuscarpio) and fancy koi (Cyprinus carpio) from KHV (koi herpesvirus) infection in Indonesia. One of KHV glycoproteingenes, i.e. glycoprotein (GP) was ligated with Japanese medaka (Oryzias latipes) â-actin promoter to generatepAct/GP as a DNA vaccine. Fourty fish in body weight of 10-15 g/fish were individually injected by pAct/GP intomuscle in different dosage of 2.5 μg, 7.5 μg and 12.5 μg/100 μl phosphate buffer saline. Total RNA was extractedfrom the 12.5 μg of pAct/GP-injected fish muscle at 24, 48 and 67 hours post-injection to analyze GP expression byRT-PCR method. Potential of pAct/GP as DNA vaccine was examined by injecting KHV into the 30-days-vaccinatedfish. Both of possitive and negative control fish group were not vaccinated. Possitive control fish group wereinjected with KHV, but negative control fish group were not. KHV-challenged fish were reared for 1 month, and thedeath fish were calculated daily. Result of RT-PCR analysis showed that GP gene expression were detected at 3 dpost-injection. Expression of GP in the vaccinated fish groups helped to improve their survival rate after challengedby KHV. All of fish without DNA vaccination had dead 17 days after KHV injection. The results demonstrated thatpAct/GP had high potency to be used as a DNA vaccine against KHV infection in cyprinids.

Abstract

The studywas conductedtodetermine thedose of recombinant common carp growth hormone (rCcGH) supplemented in the commercial diet that generates the best performanceonbodyweight, biomass, andfeed conversion rate of juvenile tilapia.The dose of rCcGH administered was10, 20, and30mg/kg of commercial feed, andnorGH supplementation as control. Eachtreatment was designed in triplicates. Juveniles at average bodylengthof about2cm(average body weight of 0.7 g) were reared in a density of25fish/m2, for three weeks in hapa net at a size of 2×2×1 m3. Fish were fed diet containing rCcGH twicea week with an interval ofthreedays. The juvenile were fed with the rCcGH supplemented diet three times daily at satiation. The results showedthat average body weight andbiomass of fish treated by rCcGH with the doses of 20 and 30 mg/kg feed was higher (p<0.05) than that of 10 mg/kg and control. In addition, feed conversionrate of 20 and 30 mg/kg feed treatments was lower (p<0.05) than that of 10 mg/kg and control. RT-PCR analysisshowedthat expression level of IGF-1 gene in juvenile liver was increased in parallel with the increasing of rCcGH dosages supplemented in diet.This suggestedthatIGF-1 plays an important rolein the induction ofgrowth,andfeed conversionefficiencyof tilapiafed diet containing rCcGH. The bestperformance of juvenile can be obtainedby feeding with diet containingrCcGH20‒30mg/kgof feed. Keywords: rCcGH, IGF-I, recombinant growthhormone,performance, Nile tilapia.

Abstract

This study was aimed to determine the immersion frequency of recombinant growth hormone (rGH) in the growth stimulation of giant gourami juvenile. A total of 50 larvae at second day after first feeding, was immersed in 30 ppt salt water for 2 minutes, and then transferred into 200 mL of 9 ppt salt water containing 30 mg/L rGH in inclusion bodies form. Immersion was performed for 60 minutes and repeated once a week for two, three, four, and five weeks. As the control, fish was immersed with inclusion bodies without rGH (control-1), bovine serum albumin (control-2), 9ppt saline water without rGH (control-3) and in freshwater (control-4). Fish were kept in 7L aquaria during the first four weeks, transferred into 50L aquaria for two weeks, and then in hapa (2×1×1 m3 in size) for two weeks. The results showed that the highest (p<0.05) average body weight of giant gourami juvenile (2.23±0.19 g) was obtained at four times (four weeks) immersion treatment. Similar body weight of fish in two times (1.72±0.29 g), three times (1.68±0.34 g), and five times (1.81±0.17 g) immersion was obtained. Fish body weight of all controls was lower than the rGH-immersed fish. Average body weight of four time rGH-immersed fish (4.01 g) remained higher than other treatment and control (1.96 to 2.36 g) on 8th week of fish rearing. Survival of four times (96.67±1.15%), and five times rGH-immersion fish (95.33±4.16%) was similar, and higher than other treatments and controls (77.33 to 89.33%). Thus, higher growth rate and survival of giant gourami juvenile could be achieved by four times rGH immersion. Keywords: recombinant protein, growth hormone, immersion frequency, giant gourami

Abstract

ABSTRACT The neon tetra Paracheirodon innesi is one of the most popular ornamental fishes in the world. Its productivity seemed low because of the relatively low fecundity and hard to maintain the spawning condition. Transplantation of neon tetra testicular cells to common carp as surrogate broodstock, is a potential breakthrough for mass production of juvenile. We developed testicular cell transplantation by optimizing the size of donor that have highest spermatogonia proportion and testicular cell colonization level. The neon tetras divided into three groups of size based on the total body length (TL), namely: small (TL<18.00 mm), medium (TL=18.00–23.00 mm), and large (TL>23.00 mm). Then, we defined histomorphological characteristic of neon tetra testicular cells including diameter and volume of cell. Gonado somatic index (GSI) and proportion of spermatogonia from each group were also measured to determine group with highest spermatogonia proportion. Neon tetra testicular cells from each group that contain spermatogonial cells, were then injected into common carp larvae to examine it’s colonization level. The results of testicular cells histomorphological characteristic analysis showed that spermatogonia mean diameter and cell volume were 6.75±1.30 µm and 1,420.50±768.20 µm3, respectively. Medium-size fish group showed the highest spermatogonia proportion (20.95±1.29%) and also testicular cells colonization level (85.00±7.07%). In conclusion, as donor for testicular cells transplantation, medium-size neon tetra was better than large and small size. Keywords: testicular cells, transplantation, colonization, common carp, neon tetra  ABSTRAK Ikan neon tetra Paracheirodon innesi merupakan salah satu ikan hias paling populer di dunia. Produktivitas ikan ini rendah karena memiliki fekunditas yang relatif sedikit dan kondisi pemijahan yang sulit dipenuhi. Transplantasi sel testikular ikan neon tetra kepada ikan mas sebagai induk semang merupakan terobosan potensial untuk produksi benih secara massal. Pada penelitian ini, transplantasi sel testikular dikembangkan melalui optimasi ukuran donor yang memiliki proporsi spermatogonia dan kolonisasi sel testikular tertinggi. Ikan neon tetra dibagi ke dalam tiga kelompok berdasarkan panjang total badan (PT), yaitu small (PT<18,00 mm), medium (PT=18,00–23,00 mm), dan large (PT>23,00 mm). Selanjutnya, ditentukan karakteristik histomorfologi dari sel testikular ikan neon tetra yang meliputi diameter dan volume sel. Indeks kematangan gonad (IKG) dan proporsi spermatogonia dari setiap kelompok juga diukur untuk menentukan kelompok dengan proporsi spermatogonia tertinggi. Sel testikular ikan neon tetra dari setiap kelompok ukuran yang mengandung sel spermatogonia selanjutnya diinjeksikan kepada larva ikan mas untuk mengevaluasi tingkat kolonisasinya. Hasil dari analisis karakteristik histomorfologi sel testikular menunjukkan bahwa rerata diameter dan rerata volume sel spermatogonia berturut–turut adalah 6,75±1,30 µm dan 1.420,50±768,20 µm3. Kelompok ikan ukuran medium memperlihatkan proporsi spermatogonia (20,95±1,29%) dan sekaligus tingkat kolonisasi sel testikular (85,00±7,07%) tertinggi. Dapat disimpulkan bahwa sebagai donor untuk transplantasi sel testikular, kelompok ikan neon tetra ukuran medium lebih baik dibandingkan dengan ukuran large dan small. Kata kunci: sel testikular, transplantasi, kolonisasi, ikan mas, ikan neon tetra
