Growth of giant gourami is relatively slow. Administration of recombinant growth hormone (rGH) by severaltimes immersion in water containing 0.9% NaCl for one hour can significantly increase the growth. In thisstudy, giant gourami juvenile were immersed in freshwater containing 120 mg/L rGH to determine the longimmersion time that provides higher growth and survival. Juvenile at seventh-day-old after egg yolk absorbedwas immersed for 0.5, 1.0, 2.0, and 3.0 hours in rGH solution. As controls, fish was immersed in freshwaterwithout rGH (control 1: C1), and water containing 0.9% NaCl, and 120 mg/L rGH (control 2: C2). Fish waskept under controlled conditions in 20 L aquarium for three weeks, then in 50 L aquarium until at end ofexperiment, and fed at satiation. The results showed that highest growth in body weight, survival, and biomass(p<0.05) were obtained in rGH immersion treatment for 0.5 hour. Biomass of fish immersed by rGH for 0.5hour was about 32% higher compared to control C1, and 13% compared to C2. Survival of the 0.5 hour rGHimmersedfish (100%) was similar to control C1 and C2. Thus, immersion of giant gourami juvenile infreshwater containing rGH for 0.5 hour allowed highest growth rate, and this method is relatively easy to beadopted by fish hatchery.Keywords: immersion, hormone, growth, freshwater, giant gourami

ABSTRACT Transplantation technology can be applied to generate fish surrogate broodstock. A donor germinal cells that was used in transplantation are labeled to distinguish it with endogenous cells. Donor cells are generally derived from transgenic fish carrying a marker or cells labeled by PKH-26. This study was performed to obtain an alternative method of cell labelling using electroporation. Testicular cells were taken from 4-months old Nile tilapia as a model. Electroporation was performed with testicular cell density of 104 cells/µL, pJfKer-GFP concentration of 50 ng/µL, and a pulse length of 20 ms at 0, 100, 200, and 300 volts. At amount of 5x103 cells/0.5µL electroporated testicular cells were then injected into the intraperitoneal cavity of 3-day-old Nile tilapia larva. The results showed that survival of the electroporated cells of 100 and 200 volt-treatments was similar (P>0.05), and higher than 300 volt (P<0.05). Number of fluorescent cells was not significantly different among treatments. The highest cell colonization in transplanted fish was obtained in 200-volt treatment (66.67%). As conclusion, 200-volt electroporation with was a suitable tool to label testicular cells for transplantation. Keyword: electroporation, GFP, label, Nile tilapia, transplantation ABSTRAK Teknologi transplantasi merupakan suatu teknologi yang dapat menghasilkan induk pengganti. Sel donor berupa sel germinal yang akan digunakan dalam transplantasi diberi label agar dapat dibedakan dengan sel resipien. Umumnya sel donor diperoleh dari ikan transgenik yang membawa marka atau diwarnai dengan PKH-26. Penelitian ini bertujuan untuk mencari metode alternatif dalam pemberian label pada sel dengan elektroporasi. Sel testikular diperoleh dari ikan nila berumur empat bulan sebagai model. Elektroporasi dilakukan dengan kepadatan sel 104 sel/µL, konsentrasi pJfKer-GFP 50 ng/µL, dan panjang kejut 20 ms pada 0, 100, 200, dan 300 volt. Sebanyak 5x103 sel dalam 0,5 µL larutan hasil elektroporasi disuntikkan ke dalam rongga intraperitoneal larva berumur tiga hari setelah menetas. Hasil penelitian menunjukkan bahwa kelangsungan hidup sel pada kejut 100 dan 200 volt tidak signifikan (P<0,05), akan tetapi lebih tinggi bila dibandingkan dengan perlakuan 300 volt (P<0,05). Jumlah sel yang berpendar tidak berbeda antara perlakuan. Persentase kolonisasi sel pada ikan hasil transplan tertinggi pada perlakuan 200 volt (66,67%). Kesimpulan yang diperoleh dari hasil penelitian adalah perlakuan elektroporasi dengan kejut listrik 200 volt dapat digunakan untuk memberi label pada sel testikular yang akan ditransplantasikan.

ABSTRACT Artificial reproduction of eel Anguilla bicolor is not yet well-established because of insufficient broodstock number. In this research, induction of Indonesian eel gonad maturation was performed by hormonal with a combination of pregnant mare serum gonadotropin (PMSG), human chorionic gonadotropin (HCG) antidopamin and recombinant growth hormone (rGH). This research consisted of five treatments namely: control (NaCl 0,9%), PMSG 20 IU/ kg, PMSG 20 IU/kg + antidopamin 10 ppm/kg, PMSG 20 IU/kg + antidopamin 10 ppm/kg + rGH 10 μg/kg dan PMSG 20 IU/kg + HCG 10 IU/kg. Each treatment contained 10 fishes. Hormonal induction was conducted by intramuscular injections, as much as five times at intervals of seven days. Furthermore observations on gonadal development were performed after injection for 21 days. The results showed that the treatment generated pregnancy level of 100%, while control was 0%. The best treatment was PMSG 20 IU/kg + antidopamin 10 ppm/kg+ rGH 10 μg/kg, seen from a more mature phase of the gametes, spermatocytes in male and oocytes with perinukleolar phase in female fish. Eel at the body weight of 120.4 to 207.8 g and at the body length of 40.9 to 43.1 cm was male, at the body weight of 274.8 g and at the body length of 47 cm was in intersexual phase, and at the body weight of 323.4 g and at the body length of 53 cm was female.
