The methods for hormonal control of shrimp reproduction are very limited, and only eyestalk ablation is used to induce ovarian development and spawning in shrimp farming. The occurrence of vertebrate-type steroid hormones in crustaceans have been reported, however, their physiological role are not sufficiently understood. The present study analyzed the effect of estradiol-17β injection on gonad development of white shrimp, Litopenaeus vannamei. The estradiol-17β dose 0.10 μg/g body weight were used. The treatments consisted of control, single injection (day 0) and double injection (day 0 and 6). The females broodstock were cultured for 12 days. The result showed that estradiol-17β had positive effect on gonad development. The gonado somatic index (GSI) and oocytes diameter in treatment larger than the control. Double injection had highest effect with ∆GSI and oocytes diameter was 0.453 and 23.97 µm, respectively. The only oocytes previtelogenesis was found in gonad. It indicated that estradiol-17β important to induce endogenous vitellogenesis. Gonad development probably affected by gonad inhibiting hormone in the eyestalk. It was inhibited oocyte maturation. The polypeptide sub unit was observed in vitellin of ovari by SDS-PAGE. The molecular weights of approximately 95, 98, 109 and two units higher than 118 kDa of protein marker. Keywords: Gonad, estradiol-17β, oocyte, Litopenaeus vannamei ABSTRAK Teknologi reproduksi dalam pembenihan udang belum mengalami perkembangan yang signifikan. Pada umumnya untuk mempercepat kematangan gonad induk udang digunakan teknik ablasi. Mekanisme dan peranan hormon pada proses reproduksi udang belum banyak diketahui. Keberadaan hormon steroid pada krustase telah dikemukaan oleh beberapa peneliti, tetapi peranannya belum banyak diketahui. Pada penelitian ini dikaji pengaruh penyuntikan hormon estradiol-17β pada perkembangan gonad induk udang putih (Litopenaeus vannamei). Penelitian ini menggunakan dosis 0,10 μg/g bobot tubuh dengan perlakuan penyuntikan tunggal (hari ke-0) dan ganda (hari ke-0 dan ke-6). Sebagai pembanding dilakukan uji tanpa perlakuan (kontrol). Untuk melihat respon perkembangan gonad, pemeliharaan induk dilakukan selama 12 hari. Hasil penelitian menunjukkan bahwa estradiol-17β berpengaruh positif pada perkembangan gonad. Gonado somatic index (GSI) dan rata-rata diameter oosit pada perlakuan relative lebih tinggi dibandingkan kontrol. Penyuntikan ganda memberikan pengaruh paling besar dengan peningkatan GSI sebesar 0,453 dan rata-rata diameter oosit 23,97 µm. Oosit pada gonad hanya mampu berkembang hingga tahap previtelogenesis. Hal ini menunjukkan bahwa estradiol-17β berperang dalam vitelogenesis endogenous. Keberadaan hormon penghambat perkembangan yang dihasilkan tangkai mata diduga menyebabkan oosit tidak dapat mencapai matang. Analisis SDS-PAGE menunjukkan bahwa protein kuning telur pada gonad terdapat 5 sub unit dengan perkiraan bobot 95, 98, 109 kDa dan dua unit >118 kDa. Kata kunci: Gonad, estradiol-17β, oosit, Litopenaeus vannamei

In developing fish cultivation, it is better to make an effort to support a sustainable larva availability with the high quality and quantity. This is due that the larva stadium is a susceptible phase and the most critical condition in a whole fish life cycle. Hence, in obtaining a life cycle sequence and high quality of the fish, the most important thing to do is providing natural foods of the fish. One of them is Chlorella sp, this species has the size which is suitable to the orifice of the larva and it contains high nutrient such as protein. This research aims to investigate the effect of adding a growth regulator substance in cultural PHM media on the protein content of Chlorella sp. The method used in this research was experimental laboratory using a completely random design which comprised of five treatments with triplicates per treatment. Treatments A (PHM + PSB 0.005 mL/L), B (PHM + PSB 0.01 mL/L), C (PHM + PSB 0.015 mL/L), D (PHM + PSB 0.02 mL/L), and K (PHM without PSB). Parameters observed and analysed were growth and protein content of Chlorella sp. During the study, parameters of the water quality measured were temperature (0C), pH, ammoniak, nitrit, and nitrat. The results of the study showed that adding a growth regulator Penshibao (PSB) in the media with various doses gave significant effects (P

Highly unsaturated fatty acids (HUFA), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have long been recognized for its beneficial effect for human health and development. The D6 fatty acid desaturase is generally considered to be the rate-limiting factor in HUFA biosynthesis. Here, as the first step of study, we conducted experiment to select an appropriate construct that allows higher expression levels of masu salmon (Oncorhynchus masou) D6-desaturase gene in zebrafish (Danio rerio) in order to increase its activity for synthesizing EPA/DHA. Salmon D6-desaturase cDNA (sD6) was separately ligated with human cytomegalovirus (hCMV), medaka elongation factor 1a (mEF1a) and medaka b-actin (mAct) promoters. The resulted construct was designated as hCMV-sD6, mEF1a-sD6 and mAct-sD6, respectively. Each of the constructs in circular DNA form was microinjected into 1-cell stage embryos at a concentration of 30mg/ml. Transgenic individuals were identified by polymerase chain reaction (PCR) and their expression levels were analyzed by reverse transcription PCR. The first (F1) and second (F2) generation was produced by crossing the transgenic founder F0 and F1, respectively, with wild-type fish. The results showed that the highest transient gene expression level was obtained from the mAct-D6 construct, followed respectively by EF1a-D6 and hCMV-D6 construct. The transmission rate of transgene into F1 generation was 4.2%-44.1%, and into F2 was followed the Mendellian segregation pattern. Expression of transgene in F2 generation was varied between strains regarding as the mosaics of F0 fish. Now, a transgenic system to study the modification of fatty acid biosynthesis pathways in fish was established. Further investigations are to produce fish containing higher levels of EPA and DHA. Keywords: desaturase, nutraceutical fatty acid, transgenic, zebrafish, masu salmon Abstrak Promoter merupakan regulator yang menentukan tempat, waktu dan tingkat ekspresi gen. Pada penelitian ini, kami melakukan seleksi kontruksi plasmid yang tepat yang menghasilkan tingkat ekspresi yang tinggi dari gen D6-desaturase-like ikan masu salmon (Oncorhynchus masou) yang ditransfer ke ikan zebra (Danio rerio) untuk meningkatkan kemampuannya dalam mensintesa EPA/DHA. cDNA D6-desaturase-like (OmD6FAD) dari ikan salmon masu diligasi secara terpisah dengan promoter dari cytomegalovirus manusia (hCMV), elongation factor 1a (mEF1a) dan b-actin (mbAct) dari ikan medaka, untuk membuat konstruksi plasmid yang berturut-turut disebut sebagai hCMV-OmD6FAD, mEF1a- OmD6FAD dan mbAct-OmD6FAD. Konstruksi tersebut dengan konsentrasi 30mg/ml disuntikkan ke embrio pada saat fase satu sel. Individu transgenik diidentifikasi menggunakan PCR dan tingkat ekspresi transgen dianalisa dengan RT-PCR. Hasil menunjukkan bahwa tingkat ekspresi sementara yang tertinggi dari gen asing adalah diperoleh dari konstruksi mbAct-OmD6FAD, diikuti selanjutnya oleh EF1a-OmD6FAD dan hCMV- OmD6FAD. Transgen telah ditransmisikan ke ikan generasi F2 dengan mengikuti pola segregasi Mendel. Tingkat ekspresi transgen yang tinggi pada jaringan ikan F2 yang diperiksa telah diperoleh. Dengan demikian, sebuah sistem transgenik untuk memodifikasi biosistesa asam lemak pada ikan telah dikembangkan. Kata kunci: promoter, desaturase asam lemak, transgenik, ikan zebra, ikan salmon masu

This experiment was conducted to evaluate the effect of catfish body fat in the diet on the growth of tilapia Oreochromis niloticus. Twenty fishes with an initial body weight of 5.0±0.03 g were cultured in 100-ℓ rectangular aquaria for 58 days. The fishes were fed on the diet contained lipid from catfish at a dosage of either 0, 1.5, 3, 4.5 or 6%. The results showed that lipid dosage in the diet insignificantly affected feed efficiency, (73.25-81.96%), protein retention (45.57-51.56%), daily growth rate (4.05-4.29%), and survival rate of fish (98.33-100%). However, n-3 fatty acids of fish muscle elevated as the dosage of body fat of catfish in the diet increased. Therefore, it can be concluded that lipid from catfish can be used as a fat source in the diet of tilapia. Keywords: lipid, tilapia, Oreochromis niloticus Abstrak Penelitian ini bertujuan untuk mengetahui pengaruh tingkat penggunaan lemak patin dalam pakan buatan terhadap pertumbuhan ikan nila Oreochromis niloticus. Dua puluh ekor ikan nila dengan bobot rata-rata 5±0,03 g ditebar ke dalam akuarium 60x50x40 cm. Ikan dipelihara selama 58 hari. Selama masa budidaya, ikan diberi lima jenis pakan berkadar protein 28% yang mengandung lemak patin pada kadar 0, 1,5, 3, 4,5 atau 6%. Hasil penelitian menunjukkan bahwa penambahan lemak patin pada pakan tidak memberikan pengaruh yang berbeda terhadap nilai efisiensi pakan (73,25-81,96%), retensi protein (45,57-51,56%), laju pertumbuhan harian (4,05-4,29%) dan kelangsungan hidup ikan (98,33-100%). Namun, semakin meningkatnya kandungan lemak patin di dalam pakan berakibat pada semakin tingginya kandungan asam lemak n-3 di dalam daging ikan. Dari hasil penelitian ini dapat disimpulkan bahwa lemak patin dapat digunakan sebagai sumber lemak tambahan dalam pakan buatan ikan nila. Kata kunci: lemak, ikan nila, Oreochromis niloticus
