Budidaya ikan kakap sering terkendala dengan kurang tersedianya pakan rucah secara kontinyu dan berkelanjutan, karena pakan rucah tersedia secara musiman. Budidaya ikan kakap harus diselingi dengan pemberian pakan pelet, apalagi pakan pelet yang diperkaya dengan hormon pertumbuhan rekombinan dapat menjadi salah satu solusi. Mempercepat laju pertumbuhan ikan dapat dilakukan dengan pemberian hormon pertumbuhan rekombinan. Hormon tersebut dijadikan sebagai sumplemen pakan bagi ikan maupun udang. Tujuan penelitian ini adalah untuk meningkatkan laju pertumbuhan ikan kakap menggunakan hormon pertumbuhan rekombinan yang dibudidayakan dengan sistem keramba jaring apung di Teluk Talengen. Tahapan penelitian terdiri dari persiapan wadah dan ikan uji, pembuatan pakan dan pemeliharaan selama 30 hari. Perlakuan yang dilakukan adalah dosis hormon pertumbuhan rekombinan yang diaplikasikan ke pakan dan diberikan pada ikan kakap. Dosis yang diberikan adalah : 0 mg/kg, 2 mg/kg, 3 mg/kg, dengan tiga kali ulangan. Ikan kakap yang digunakan berukuran 3-5 cm dengan padat tebar 10 ekor per wadah. Dosis hormon pertumbuhan rekombinan akan dicoating menggunakan putih telur dan disemprot ke pakan. Pemberian pakan dilakukan secara at satiation dengan frekuensi pemberian sebanyak 2 kali pada pagi dan sore hari. Hasil penelitian memperlihatkan perlakuan terbaik yaitu dosis 3 mg/kg pakan meningkatkan bobot tubuh (8,8 gr), SGR (3,43%), EP (28,3%) dan SR (100%) dibandingkan perlakuan kontrol. Hal tersebut menunjukkan hormon pertumbuhan rekombinan memberi pengaruh positif meningkatkan laju pertumbuhan dan survival rate ikan kakap selama 30 hari pemeliharaan.   Snapper cultivation is often constrained by the lack of continuous and sustainable feed availability, because trash feed is readily available. The cultivation of snapper fish must be interspersed with providing pellet feed, moreover pellet feed enriched with recombinant growth hormone can be a solution. Accelerating the growth rate of fish can be done by offering recombinant growth hormone. This hormone is used as a supplement to feed for fish and shrimp. The aim of this study was to increase the growth rate of snapper using recombinant growth hormone cultivated with floating net cage system in Talengen Bay. Stages of taking care of research from containers and test fish, making feed and maintaining it for 30 days. The treatment is a recombinant growth hormone which is applied to feed and given to snapper. The doses given were: 0 mg/ kg, 2 mg/kg, 3 mg/kg, with three replications. The snapper used is 3-5 cm in size with a stocking density of 10 fish per container. The dose of recombinant growth hormone will be coated using egg white and sprayed into the feed. Feeding is done occasionally with a frequency of offering 2 times in the morning and evening. The results of the best treatment treatment, namely the dose of 3 mg / kg of feed increased body weight (8.8 gr), SGR (3.43%), EP (28.3%) and SR (100%) compared to control treatment. This shows that the growth of recombinant growth hormone has a positive effect on increasing the growth rate and survival of snapper for 30 days of rearing.

Despite as high price consumption fish, humpback grouper grow out take very long time so its culture considered not efficient. Therefore to accelerate its growth rate and make grow out culture more efficient, recombinant Epinepheluslanceolatus growth hormone (rElGH) was applied by oral route. Daily application of rough rElGH at a dose of 5 mg/100 g commercial diet for 42 days resulted significance increase in growth rate compared to control groups. No specific histological damage on kidney, liver and spleen which was attributable to rElGH administration. These results strongly suggested that growth stimulation following oral administration was due to a specific action of rElGH and recombinant GH as mentioned above save for fish consumption. Keywords: growth, histology, humpback grouper, recombinant growth hormone

<p>Growth of giant gourami is relatively slow. Administration of recombinant growth hormone (rGH) by several<br />times immersion in water containing 0.9% NaCl for one hour can significantly increase the growth. In this<br />study, giant gourami juvenile were immersed in freshwater containing 120 mg/L rGH to determine the long<br />immersion time that provides higher growth and survival. Juvenile at seventh-day-old after egg yolk absorbed<br />was immersed for 0.5, 1.0, 2.0, and 3.0 hours in rGH solution. As controls, fish was immersed in freshwater<br />without rGH (control 1: C1), and water containing 0.9% NaCl, and 120 mg/L rGH (control 2: C2). Fish was<br />kept under controlled conditions in 20 L aquarium for three weeks, then in 50 L aquarium until at end of<br />experiment, and fed at satiation. The results showed that highest growth in body weight, survival, and biomass<br />(p&lt;0.05) were obtained in rGH immersion treatment for 0.5 hour. Biomass of fish immersed by rGH for 0.5<br />hour was about 32% higher compared to control C1, and 13% compared to C2. Survival of the 0.5 hour rGHimmersed<br />fish (100%) was similar to control C1 and C2. Thus, immersion of giant gourami juvenile in<br />freshwater containing rGH for 0.5 hour allowed highest growth rate, and this method is relatively easy to be<br />adopted by fish hatchery.</p><p>Keywords: immersion, hormone, growth, freshwater, giant gourami</p>

Ikan semah (Tor douronensis) termasuk salah satu spesies dari genus Tor yang memiliki nilai ekonomis tinggi. Untuk meningkatkan produktivitas, informasi pertumbuhan benih yang dipelihara pada sistem budidaya karamba jaring apung (KJA) perlu dilakukan karena ikan semah umumnya dibudidayakan pada kolam dengan air yang jernih. Penelitian ini bertujuan untuk mendapatkan informasi laju pertumbuhan benih ikan semah generasi pertama dengan perlakuan padat tebar yang berbeda pada sistem pemeliharaan KJA. Percobaan dilakukan di Waduk Cirata, Cianjur, Jawa Barat selama lima bulan. Ikan uji (panjang total: 7-8 cm; bobot: 5-6 g) dipelihara di KJA (padat tebar 50, 75, dan 100 ekor/m3 dengan tiga kali ulangan). Pakan apung komersial dengan kadar protein 40% diberikan sebesar 6% per biomassa yang diberikan dua kali sehari. Parameter yang diamati yaitu pertumbuhan bobot mutlak, sintasan, laju pertumbuhan spesifik (SGR), dan biomassa. Hasil percobaan menunjukkan bahwa perlakuan padat tebar 50 ekor/m3 menghasilkan pertumbuhan terbaik dengan bobot akhir 15,89 ± 1,43 g; pertambahan mutlak 10,48 ± 1,41 g; sintasan 94,67 ± 4,6%; dan SGR 0,75 ± 0,04%. Dari hasil penelitian ini, padat tebar 50 ekor/m3 merupakan kondisi yang terbaik untuk pemeliharaan benih ikan semah di KJA. Hasil penelitian ini dapat dijadikan informasi awal tentang potensi budidaya ikan semah dengan sistem budidaya KJA perlu dikembangkan di masa yang akan datang.Semah mahseer (Tor douronensis) is a species from the genus Tor and highly valued in local and national markets. Nevertheless, the fish production from net cage is currently limited. In order to increase its productivity, research on the growth of semah mahseer fingerlings reared in floating net cage systems needs to be carried out as this species is predominantly cultured in the clean water ponds. This study was conducted to obtain information on the growth performance of the first generation of semah mahseer fingerlings reared with different stocking densities in a floating net cage system. The experiment was carried out in the floating net cage located at Cirata Reservoir, Cianjur, West Java, for five months. Fingerlings (total length: 7-8 cm; body weight: 5-6 g) were reared in the floating net cage (stocking density of 50, 75, and 100 ind./m3 with three replications). The fish were fed with a commercial diet (protein content of 40%) given at 6% of biomass twice a day. The parameters observed included weight gain, survival rate, specific growth rate (SGR), and biomass. The results showed that the stocking density of 50 ind./m3 had the best performance in terms of final weight of 15.89 ± 1.43 g, weight gain of 10.48 ± 1.41 g, survival rate of 94.67 ± 4.6%, and specific growth rate of 0.75 ± 0.04%. Based to the results of this study, the stocking density of 50 ind./m3 is the best condition for rearing semah mahseer fingerlings in floating net cages. The findings of this research can be used as the basic information for future aquaculture development of semah mahseer in net cages.

The present work was designed to study the influence of therapy with recombinant growth hormone on the oxygen and antioxidant blood status in the children presenting with somatotrophic insufficiency. A total of 11 children (2 girls and 9 boys) at the age from 3 to 9 years with confirmed somatotrophic insufficiency were available for the observation. They had never before been treated with growth hormone preparations. The blood oxyhemoglobin level and superoxide dismutase (SOD) activity increased within 3 months after the onset of therapy. There is direct correlation between oxyhemoglobin levels and SDS for the growth rate (r= 0.64; p<0.05) and negative correlation between mean hemoglobin content in erythrocytes (MHCE) and SDS for the growth rate (r=-0.69), p<0.05). The results of the study suggest the close relationship between the system of growth hormone/growth factors and the morphofunctional state of erythrocytes. It is concluded that the short-term treatment of the children suffering somatotrophic insufficiency with recombinant growth hormone appears to promote the development of adaptive mechanisms.

This study examined the effect of stocking density on growth and survival of tilapia cultured in biofloc technology system. Three different stocking densities cultured in biofloc technology were 6 fish/m3, 8 fish/m3 and 10 fish/m3 for 86 days in triplicate for each treatment. The stocking density of the control lot was 3 fish/m3 cultured without biofloc technology. Initial stocking weight ranged from 2–3 g/fish. The water quality parameters were monitored and regulated in the suitable ranges for biofloc technology and for the growth and development of tilapia. The results showed that specific growth rate of fish cultured at a density of 6 fish/m3 was higher than that in the treatments of 8 fish/m3 and 10 fish/m3 with the average values of 5.72%; 5.62% and 5.43%, respectively, and the specific growth rate of fish in the control treatment was 5.71%. Daily growth rate of fish cultured at a density of 6 fish/m3 was higher than that cultured at densities of 8 fish/m3 and 10 fish/m3 with average values of 3.19 g/day, 2.98 g/day, and 2.55 g/day, respectively; and the daily growth rate of the control treatment was 3.27 g/day. Survival rate of tilapia cultured at densities of 6 fish/m3 and 8 fish/m3 was 100%, whereas survival rate of tilapia cultured at a density of 10 fish/m3 was 95.75%, and it was 88.9% for the control lot. The research results provide a scientific basis to propose tilapia culture technique in biofloc technology in brackish water, with the density of 6–8 fish/m3.
