One of methods could be applied to continuously meet the need of fish fry including catfish (Clarias sp.) is artificial propagation by inducing ovulation and spawning. As an alternative of existing method, in this study, ginger extract was intramuscularly injected to induce development of catfish eggs. Ginger is known as an important regulator of the balance of arachidonat cycle. The dose of ginger extract injected was 0, 0.5, 1.0 and 1.5 mL/kg broodstock. The results of study showed that injection 100% of ginger extracts in all doses was insignificantly inducing development of egg diameter and its nucleus position of catfish. Other chemicals exist in ginger extract might be functions as an obstacle for egg development of catfish. Keywords: catfish, Clarias sp., ginger, ovulation, egg ABSTRAK Salah satu cara untuk memenuhi kebutuhan benih ikan termasuk lele (Clarias sp.) secara kontinyu adalah penggunaan teknologi pembiakan buatan melalui perangsangan ovulasi dan pemijahan. Sebagai alternatif teknik yang sudah ada, dicobakan perangsangan perkembangan telur ikan lele menggunakan bahan ekstrak jahe yang dilakukan melalui penyuntikan secara intramuskular. Jahe telah dikenal sebagai suatu pengatur penting atas keseimbangan siklus arakidonat. Dosis ekstrak jahe yang disuntikkan adalah 0, 0,5, 1 dan 1,5 mL/kg induk. Penyuntikan 100% ekstrak jahe pada semua dosis perlakuan belum dapat merangsang perkembangan diameter dan posisi inti sel telur ikan lele sangkuriang. Adanya bahan lain yang terdapat pada jahe diduga sebagai penghambat bagi perkembangan telur ikan lele. Kata kunci: Ikan lele, Clarias sp., jahe, ovulasi, sel telur

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

Cholesterol is known to play an important role in nutrition of crustacean and function as a precursor for steroids synthesis, while neurohormone of serotonin could induce ovarian maturation in crustacean. Ovarian development of adult females Scylla serrata was induced by adding cholesterol in the diet and serotonin injection. This research was designed to study the effectiveness of cholesterol supplementation and serotonin injection in ovarian development. Broodstocks were stocked in nine experimental units in three fiber tanks. The fiber tank was equipped with sands substrate and flow through seawater system. The experimental crabs were assigned into a completely randomized design with a 3 x 3 factorial arrangement. The first factor was cholesterol supplementation in the diet with 3 levels (0, 0,5 and 1,0%). The second factor was serotonin injection with 3 levels (0, 5 and 10 μg/g BW). Samples of broodstock were taken every four days to evaluate the stages of ovarian maturity and parameters were used to evaluate the ovarian maturation stage are gonad index (GI) and oocyte diameter, concentration of estradiol 17β, yolk protein concentrations, and fecundity. Results showed that female crabs supplemented with 0,5% cholesterol and a combination of cholesterol 0,5% supplementation and injection serotonin with a dose of 10 μg/g BW had better reproduction development. It is concluded that ovarian development of Scylla serrata could be improved by cholesterol supplementation and serotonin injection. Key words: Cholesterol, serotonin, ovarian development, Scylla serrata ABSTRAK Kolesterol diketahui merupakan nutrien spesifik yang berperan dalam sisntesis hormon steroid dan mengontrol reproduksi, sementara serotonin merupakan salah satu neurohormon yang dilaporkan dapat merangsang pematangan ovari dan pemijahan pada krustase.

Seahorse, (Hippocampus barbouri) is one of marine living resources having high commercial values and has commonly been traded especially as live ornamental aquarium fish, raw material of traditional medicine and as souvenirs. This expriment was conducted to determine the succces of spawning rate by replacing the broodstock pair of seahorse. This study was done experimentally with treatment of replacement of broodstock pair after spawning under control condition. The experiment was designed to apply completely randomize design by using the following treatments: Treatment A, without replacement neither male nor female. Treatment B, spawned female broodstock was being mated with her unpaired male broodstock. Treatment C, a male broodstock that still brood was being mated with his unpaired female broodstock. Treatment D, a spawned male broodstock that has released larva was being mated with his unpaired female broodstock. Results showed that under control condition the replacement of broodstock pairs of seahorse had significantly influenced the spawning interval, number of eggs released and number of juveniles produced (P0,05). It can be concluded that seahorse is not monogamous, either male or female after being spawned may accept other pair for the next spawning. Key words: pair replacement, broodstock, success spawning, Hippocampus barbouri ABSTRAK Kuda laut, (Hippocampus barbouri) merupakan salah satu sumberdaya hayati laut yang memiliki nilai komersial dan telah banyak diperdagangkan terutama sebagai ikan hias, bahan baku obat tradisional dan juga sebagai suvenir. Penelitian ini dilakukan dengan tujuan untuk mengkaji tingkat keberhasilan pemijahan dengan penggantian pasangan induk kuda laut pada wadah budidaya. Percobaan ini dilakukan secara ekperimental dengan perlakuan penggantian pasangan induk setelah pemijahan dalam wadah budidaya. Percobaan dirancang dengan menggunakan rancangan acak lengkap (RAL) dengan perlakuan sebagai berikut: Perlakuan A, pemijahan sepasang induk kuda laut (tanpa pergantian). Perlakuan B, pemijahan induk betina yang telah memijah dengan induk jantan bukan pasangannya. Perlakuan C, pemijahan induk jantan yang telah memijah (mengerami telur) dengan induk betina bukan pasangannya. Perlakuan D, pemijahan induk jantan yang telah melahirkan dengan induk betina bukan pasangannya. Hasil penelitian menunjukan bahwa penggantian pasangan induk pada wadah budidaya sangat berpengaruh terhadap interval pemijahan, jumlah telur yang dikeluarkan dan jumlah juwana yang dihasilkan (P0,05).
