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 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

ABSTRACT Koi herpes virus (KHV) is one of the most common impetuses for disease on common carp Cyprinus carpio. Generally, viral disease is difficult to cure because virus is intra-cellular parasite, that virus survives, multiplies, and lives only if it on the host cell. Oral vaccine delivery through Artemia sp. is of one alternative way to overcome this problem. This experiment was carried out by analysis DNA vaccine expression encoding of glycoprotein gene (GP-11) on C. carpio. Bacteria containing plasmid Krt-GP-11 as vaccine is served through Artemia sp. as a vector. Artemia sp. was given for one and two times a week to three weeks old common carp. Organs of fish fed by Artemia sp. were analyzed every three days after vaccination. The expression of GP-11 in kidney in each treatment is also observed by the use of RT-PCR method, within ten days after vaccination. The experiment showed that dose of DNA vaccine in whole bacteria could be expressed is 106 cfu/mL in a once or twice provisions a week. DNA vaccine could be detected in three organs. RT-PCR analysis also showed that the expression of GP-11 can be detected in all tested organs. In conclusion, Artemia sp. can be used as a vector to carry plasmid GP-11 vaccine for common carp Cyprinus carpio larvae. Keywords: DNA vaccine, KHV, Artemia sp., common carp ABSTRAK Salah satu penyakit pada ikan mas (Cyprinus carpio) yang disebabkan oleh virus adalah koi herpes virus (KHV). Penyakit yang disebabkan oleh virus umumnya sulit untuk disembuhkan karena virus merupakan parasit intraseluler, yaitu virus hanya dapat hidup, bertahan hidup, dan memperbanyak diri di dalam sel inang. Metode pemberian vaksin DNA secara oral melalui Artemia sp. merupakan salah satu alternatif pengobatan yang diharapkan dapat menangani permasalahan penyakit pada ikan yang disebabkan oleh virus. Pada penelitian ini dilakukan uji ekspresi vaksin DNA yang menyandikan glikoprotein 11 (GP-11) pada ikan mas. Bakteri yang mengandung plasmid Krt-GP-11 sebagai vaksin diberikan melalui Artemia sp. sebagai pembawa vaksin. Pemberian Artemia sp. dilakukan satu dan dua kali seminggu pada ikan mas umur tiga minggu. Keberadaan DNA vaksin di usus, ginjal, dan insang dianalisis menggunakan metode PCR. Organ diambil setiap tiga hari setelah pemberian vaksin. Ekspresi gen GP-11 juga diamati pada organ ginjal di setiap perlakuan dengan menggunakan metode RT-PCR, pada sepuluh hari setelah pemberian vaksin. Hasil penelitian menunjukkan bahwa DNA vaksin yang diberikan dengan dosis 106 cfu/mL pada perlakuan satu dan dua kali seminggu dapat terdeteksi pada ketiga organ. Hasil RT-PCR menunjukkan bahwa ekspresi GP-11 dapat terdeteksi pada semua organ uji di setiap perlakuan. Dengan demikian Artemia sp. dapat digunakan sebagai vektor pembawa vaksin plasmid GP-11 dengan frekuensi pemberian vaksin untuk larva ikan mas. Kata kunci: vaksin DNA, KHV, Artemia sp., ikan mas

Male giant freshwater prawn grows faster than its female. Therefore, male mono sex culture is one of the solutions to improve aquaculture production. The all-male population of giant freshwater prawns can be produced by mating the neo-females (sex-reversed males) with the normal males. This study was aimed to identify the molecular markers related to the giant freshwater prawn sex. Specific primers were designed based on female-specific AFLP marker sequences to distinguish male and female sex on the prawns. Three locations for obtaining the Indonesian prawns in this study were Aceh, Sukabumi, and Solo. Based on the PCR analysis with MrMKn primers, 30 samples of female prawns had 100 % occurred DNA bands, while no DNA bands were obtained in all-male prawns from Solo. Nevertheless, MrMKn primers still detected 10–16 % male prawns from Sukabumi and Aceh. This indicated that MrMKn primers could not yet distinguish the male prawns for all populations. Moreover, the results suggested that the three prawn samples were different based on female-specific gene sequence. The MrMKn primers have the opportunity to be used in the selection of the female ZZ (neo-female) prawns from Solo without progeny test, so that the determination of female ZZ candidates can be identified more quickly. However, the primer still needs to be redesigned to distinguish neo-female prawns from Sukabumi and Aceh. Keyword: giant freshwater prawn, mono sex, neo-female, sex markers ABSTRAK Udang galah jantan lebih cepat tumbuh dibandingkan dengan betinanya sehingga budidaya udang galah monoseks jantan menjadi salah satu solusi untuk meningkatkan produksi budidaya. Populasi monoseks jantan udang galah dapat dihasilkan dengan mengawinkan neofemales (sex-reversed males) dengan jantan normal. Sistem kromosom pada udang galah berbeda dengan ikan. Individu betina bersifat heterogametik (WZ) dan jantan homogametik (ZZ). Dalam perkembangannya, terdapat kendala dalam menentukan individu neofemale yang memiliki kromosom ZZ. Berdasarkan pendekatan sistem kromosom tersebut, maka dapat dijadikan acuan untuk membuat marka molekuler terkait kelamin udang galah. Penelitian ini bertujuan mengidentifikasi marka molekuler terkait jenis kelamin pada udang galah. Primer spesifik didesain berdasarkan sekuen female specific AFLP marker untuk membedakan kelamin jantan dan betina pada udang galah. Tiga sumber udang galah digunakan dalam penelitian ini, yaitu Aceh, Sukabumi, dan Solo. Berdasarkan hasil analisis PCR dengan primer MrKNn, dari 30 sampel pada kelompok udang galah betina diperoleh hasil 100% pita DNA muncul, dan tidak terdapat pita DNA pada semua udang galah jantan asal Solo. Namun demikian, primer MrMKn tersebut masih mendeteksi sebesar 10–16% pada udang galah asal Sukabumi dan Aceh. Hal ini menunjukkan bahwa primer MrMKn belum dapat membedakan udang galah jantan dari semua populasi. Selain itu, dapat dikatakan bahwa ketiga udang galah uji adalah berbeda, khususnya sekuen gen spesifik betina. Primer MrMKn berpeluang digunakan dalam proses seleksi udang galah betina ZZ (neofemale) asal Solo tanpa harus melalui uji progeni sehingga penentuan kandidat betina ZZ lebih cepat teridentifikasi. Akan tetapi, primer masih perlu didesain ulang untuk membedakan neofemale asal Sukabumi dan Aceh. Kata kunci: marka kelamin, monoseks, neo-female, udang galah

This study aimed to evaluate the dietary supplementation of α-lipoic acid (ALA) on the growth performance, antioxidative capacity, and protein-sparring effect of striped catfish (Pangasianodon hypophthalmus) fingerling. The striped catfish (individual weight of 1.4 ± 0.0 g) were stocked in 25 cages at 2x1x1.5 m size in a 200-m pond at 50 fish. Fish were fed formulated diets with ALA supplementation, namely: diet A (27% protein: 390 kcal), diet B (27% protein: 390 kcal +ALA 8 g/kg), diet C (27% protein: 400 kcal), diet D (27% protein: 400 kcal +ALA 8 g/kg), and diet E (30% protein: 390 kcal). Feeding was performed until apparent satiation for 60 days. The ALA supplementation significantly produced higher final individual weight, specific growth rate, and protein efficiency ratio, followed by a lower feed conversion ratio on the 27:390+ALA diet treatment (P<0.05) than other diet treatments. The highest liver performance based on superoxide dismutase enzyme activity and glycogen contents was obtained from the 27:390+ALA diet treatment. The malondialdehyde, triglycerides, and lipid accumulation in the liver on the 27:390+ALA diet treatment were lower than other diet treatments (P<0.05). Therefore, the best growth performance and physiological status in striped catfish was obtained from 27:390+ALA diet treatment.

Nomorhamphus sp. is a freshwater fish that has been traded as an ornamental fish. This fish is unique as an endemic species with a halfbeak-like jaw and orange color on the caudal fin. However, this fish culture information needs a further information. Based on this condition, it is necessary to conduct a study as a basis for ornamental fish breeding and growing-out activities through domestication. A crucial problem in this fish is larval rearing, which can be observed through ontogeny studies. The study was conducted on the newly-born larval behavior, morphological development, andropodium development, growth, and survival rate at the early stages, namely larvae to juvenile. The results showed that the newly-born larvae of Nomorhamphus sp. Lindu had a total length of 1.6-1.8 cm. Larvae could swim four hours 22 minutes after birth and feed artemia nauplii with surface feeding type. The initial juvenile stage occurred 25 days of post-birth period with a total length of 2.0-2.2 cm. The water condition of the rearing during the study could support the larval transformation to juvenile. This study is the first report related to the aquaculture success of the early life stage of Nomorhamphus sp. Lindu at the domestication stage.

This type of research is field research that uses a descriptive qualitative method. This study was conducted by collecting data and then analyzing the research results based on the facts obtained in the field. Data collection uses primary and secondary data sources. Primary data sources are literature sources such as books, journals, and dissertations that serve as supporting references in the research. Secondary data sources come from research obtained in the field through interviews and documentation to obtain clear information regarding the Ethnoastronomy of the Cilellang Fishing Community in Barru Regency from the Perspective of Astronomy. The results of the research indicate that the Cilellang Village Fishing Community still applies some elements of traditional meteorology, which we call ethnoastronomy. They use the sun, moon, and star clusters as guidelines. The movement of the sun and moon is used to determine the condition of the day and weather, whether good or bad, in their daily activities as fishermen, which is recorded in the lontara' manuscripts. Star constellations or "anak uleng" are used as natural signs to determine all directions. In the perspective of astronomy, star constellations can be used to determine the direction of the Qibla, such as the Ursa Major constellation, known as "anak uleng kappalae," which indicates the north direction, and the Orion constellation, known as "anak uleng tellue-tellue," which indicates the west direction. It is recommended that more in-depth research be conducted related to the accuracy of cardinal directions using star constellations. .Keywords: Ethnoastronomy, Fisherman Communities, Astronomy
