ABSTRACT The present study is a preliminary research for producing mullet fry to aquaculture. The research aimed to evaluate stimulation of gonad maturation in mullet (Mugil dussumieri) using hormones. The method used for research was completely randomized design consisting of three treatments and each individual replication was repeated three times. Two experiments were conducted separately with different treatments. First experiment used 9-14.7 cm body length of fish treated with different hormone injections i.e. 4 mg/kg 17α-methyltestosterone (MT), 0.07 mg/kg estradiol-17β (E2), and 0.5 ml/kg 0.9% physiological solution as control. Second experiment used 10-31 cm body length fish treated with 750 IU/kg chorionic gonadotropin (hCG), 0.5 ml/kg Ovaprim, and 0.9% physiological solution as control. Gonadosomatic index (GSI) value of the first experiment on day 60 showed that GSI of E2 treatment (1.31±0.94%) was higher than both MT treatment (1.00±0.51%) and control (0.54±0.20%). On the other hand, the second experiment on day 60 showed that GSI of hCG treatment (7.18±0.59%) was higher than both Ovaprim treatment (3.29±2.66%) and control (6.72±0.32%). Egg diameter frequency distribution for control in the first experiment on day 30 showed that egg size ranged from 9−144 µm. Egg diameter for E2 and MT treatments on day 60 showed that egg size ranged from 9−243 µm and were higher than control. In the second experiment, egg diameter on day 30 for control showed that egg size ranged from 9-144 µm, hCG treatment showed egg size ranged from 9−441 µm, while Ovaprim egg size ranged from 9-111 µm. Blood glucose, blood cholesterol, testosterone and estradiol hormone level in the first and second experiment showed no significant difference. The results showed that estradiol-17β and 17α-methyltestosterone induction in 9-14.7 cm body length mullet increase gonad maturity to stage II while hCG induction in 10-31 cm body length mullet increase gonad maturity to stage III.

Penelitian dilakukan menggunakan rancangan acak lengkap yang terdiri dari tiga perlakuan dan tiga kali ulangan individu. Terdapat dua percobaan dengan perlakuan berbeda dan dilakukan secara terpisah. Percobaan pertama menggunakan ikan berukuran 9−14.7 cm dengan hormon 17α-metiltestosteron (MT) 4 mg/kg, estradiol-17β (E2) 0.07 mg/kg dan kontrol larutan fisiologis 0.9% 0.5 ml/kg. Percobaan kedua menggunakan ikan berukuran 10−31 cm dengan human chorionic gonadotropin (hCG) 750 IU/kg, Ovaprim 0.5 ml/kg dan kontrol larutan fisiologis 0.9 % 0.5 ml/kg. Nilai gonadosomatic index (GSI) percobaan pertama pada hari ke-60 menunjukkan bahwa pemberian estradiol-17β (1.31±0.94%) lebih tinggi dibandingkan 17α-metiltestosteron (1.00±0.51%) dan kontrol (0.54±0.20%). Hasil percobaan kedua pada hari ke-60 nilai GSI menunjukkan bahwa pemberian hCG (7.18±0.59%) lebih tinggi dibandingkan Ovaprim (3.29±2.66%) dan kontrol (6.72±0.32%). Sebaran frekuensi diameter telur pada percobaan pertama untuk kontrol hari ke-30 menunjukkan kisaran 9−144 µm. Sebaran frekuensi diameter telur untuk estradiol-17β dan 17α-metiltestosteron hari ke-60 menunjukkan kisaran 9−243 µm lebih banyak dibandingkan kontrol. Sebaran frekuensi diameter telur pada percobaan kedua untuk kontrol hari ke-30 menunjukkan kisaran 9−144 µm, hCG 9−441 µm sedangkan Ovaprim hanya 9−111 µm. Kadar glukosa darah, kolesterol darah, hormon testosteron dan estradiol pada percobaan pertama dan percobaan kedua menunjukkan tidak terdapat perbedaan yang nyata. Hasil penelitian menunjukkan bahwa induksi hormon estradiol-17β dan 17α-metiltestosteron pada ikan berukuran 9−14.7 cm dapat meningkatkan kematangan gonad mencapai TKG II sedangkan induksi hormon hCG pada ikan berukuran 10−31 cm dapat meningkatkan kematangan gonad mencapai TKG III.

ABSTRACT Carotenoids were known as pigment sources, the precursor of vitamin A, potential antioxidant and can improve the health status of fish. Furthermore, there are also studies that reveal the role of carotenoids in bone formation and metabolism. This study was conducted to determine the effect of different carotenoids at two different doses in the feed on growth, pigmentation, vitamin A conversion, blood profile, antioxidant activity, and calcium bone of the rainbow fish. Twenty-one aquariums with a volume of 20 L each stocked with 20 fish (1.08 ± 0.03 g of body weight and 4.56 ± 0.07 cm of body length). The experiment applied seven experimental diets (in triplicates) consisted of three types of carotenoids were astaxanthin (AS), canthaxanthin (CS), and lutein (LS) and two doses (130 and 260 mg/kg), i.e. AS-130, AS-260, CS-130, CS-260, LS-130, LS-260 and basal (without carotenoids) as the control. The fish were fed for 56 days of experimental period. The results showed that carotenoid diets were able to increase growth, total carotenoids, percentages of chromatophores, vitamin A conversion, erythrocyte, leukocytes, packed cell volume (PCV), neutrophils, and hemoglobin (Hb) compared to the control. Fish fed dietary astaxanthin at a level of 260 mg/kg was superior compared to other diets. Dietary carotenoids were also capable of decreasing the endogenous antioxidant activity of superoxide dismutase (SOD) and malonyl dialdehyde (MDA) and increased the calcium level in fish bone than basal diet. Keywords: carotenoids, growth, health status, Melanotaenia parva, pigmentation ABSTRAK Karotenoid diketahui sebagai sumber pigmen, prekursor vitamin A, antioksidan potensial dan dapat meningkatkan status kesehatan ikan. Selain itu, karotenoid juga memiliki peran dalam formasi dan metabolism tulang. Penelitian ini dilakukan untuk mengevaluasi pengaruh jenis dan dosis karotenoid yang berbeda terhadap pertumbuhan, pigmentasi, konversi vitamin A, gambaran darah, aktifitas antioksidan dan kalsium tulang ikan rainbow Kurumoi. Sebanyak 20 ekor ikan (bobot tubuh rata-rata 1,08 ± 0,03 g dan panjang total rata-rata 4,56 ± 0,07 cm) dan diberi makan pakan yang mengandung karotenoid. Pakan uji terdiri atas tiga jenis karotenoid dengan tiga ulangan yaitu astaksantin (AS), cantaksantin (CS), dan lutein (LS) dan dua dosis (130 dan 260 mg/kg) dikodekan dengan AS-130, AS-260, CS-130, CS-260, LS-130, LS-260 dan basal (tanpa karotenoid) sebagai kontrol. Ikan diberi makan selama 56 hari pemeliharaan. Hasil penelitian menunjukkan bahwa karotenoid dapat meningkatkan pertumbuhan, total karotenoid, persentase kromatofora, konversi vitamin A, eritrosit, leukosit, hematokrit, neutrofil, dan hemoglobin dibandingkan dengan kontrol. Ikan yang diberi pakan mengandung astaksantin 200 mg/kg lebih baik dibandingkan denga pakan uji lainnya. Pakan yang mengandung karotenoid juga mampu menurunkan antioksidan endogenus superoxide dismutase (SOD) dan malonyl dialdehyde (MDA), serta meningkatkan kalsium tulang ikan dibandingkan pakan kontrol.

ABSTRACTLysozymes play an important role in the first line of defense in fish and potentially used as an immunity status biomarker and immune responses evaluation in fish, which often found in two types, i.e. chicken-type and goose-type (c- and g-type, respectively). To recent, the information related to the sequences and the expression analysis of the c- and g-type lysozyme genes in African catfish is still limited. In the present study, we report a partial cloning and mRNA expression analysis of c-type and g-type lysozymes in African catfish Clarias gariepinus. We have successfully cloned and partially identify the c-type, and g-type lysozyme genes of C. gariepinus, which consist of 594 and 560 of coding sequences, respectively. Catalytic and other conserved residues were identified by multiple sequences alignment and they showed high similarity with other teleost fish species. mRNA levels of the genes were analyzed by using qPCR method and their expressions in the spleen, liver, and head kidney were rapidly modulated after Aeromonas hydrophila injection, with different patterns were observed in each organ. These results confirmed that c- and g-type lysozymes played an important role in non-specific immunity against A. hydrophila infection. This study provided valuable information that can be used to understand the African catfish immune systems for better disease and stress management in C. gariepinus culture.Keywords: lysozymes, gene identification, gene expression, bacterial infection, African catfish ABSTRAKLisozim berperan dalam sistem pertahanan dini pada ikan dan sangat potensial digunakan sebagai marka status imunitas dalam evaluasi respons imun. Lisozim umum ditemukan dalam dua tipe pada ikan: tipe-ayam (tipe-c) dan tipe-angsa (tipe-g). Informasi terkait sekuens gen dan ekspresi gen kedua tipe lisozim pada ikan lele dumbo sangat terbatas. Pada penelitian ini, kami melaporkan kloning gen secara parsial, dan analisis ekspresi gen dari kedua tipe lisozim pada ikan lele dumbo C. gariepinus. Sekuens parsial gen lisozim tipe-c dan tipe-g yang berhasil diidentifikasi adalah sepanjang 594 dan 560 pasang basa. Situs katalitik dan residu khas memiliki tingkat kesamaan yang tinggi dengan spesies ikan yang lain. Analisis mRNA dilakukan dengan metode quantitative PCR (qPCR). Ekspresi kedua gen di jaringan ginjal depan, limpa, dan hati dengan cepat terinduksi pasca infeksi bakteri A. hydrophila dengan pola yang berbeda. Hasil ini menunjukkan bahwa lisozim tipe-c dan tipe-g memiliki peran yang sangat penting dalam sistem imun ikan lele dumbo terhadap infeksi A. hydrophila. Penelitian ini menghasilkan informasi penting yang dapat digunakan untuk mempelajari sistem imun ikan lele dumbo dan sebagai acuan dalam penanganan dan manajemen penyakit pada budidaya ikan lele dumbo.Kata kunci: lisozim, identifikasi gen, ekspresi gen, infeksi bakteri, ikan lele dumbo

ABSTRACT This study was conducted to evaluate the profile of 17ß-estradiol (E2) and vitellogenin (Vtg) in plasma and egg diameter during gonad maturity process of striped catfish Pangasianodon hypophthalmus. Blood samples were collected from immature striped catfish, male and female with different stage of gonad maturity (stage I, II, III, and IV) to measure the concentrations of E2 and Vtg. Gonad maturity development of striped catfish was observed based on egg diameter. Result showed that E2 concentrations were the highest (843.65 pg/mL) on female with maturity stage III, the lowest on the male (26.34 pg/mL), and immature female fish (29.37 pg/mL). The protein band of Vtg was obtained on the plasma of the mature female (stage I, II, III and IV) with a molecular weight (MW) between 140−180 kDa, but it was not obtained on immature female dan male striped catfish. The highest concentration of Vtg was found in the plasma of the female fish with maturity stage III (87.34 mg/mL), then on the stage II (74.83 mg/mL), I (68.58 mg/mL), and IV (33.45 mg/mL). It showed that egg yolk formation occurred in the female mature. The average egg diameter was 0.107 ± 0.052 mm, 0.318 ± 0.086 mm, 0.864 ± 0.099 mm, and 1.041 ± 0.058 mm on the maturity stage I, II, III, and IV respectively. The increase of egg diameter along with development of gonad maturity stage indicated that egg development occurred due to the process of vitellogenesis and the addition of egg yolk on oocyte. Keywords : egg diameter, gonad maturity, striped catfish , 17ß–estradiol, vitellogenin ABSTRAK Penelitian dilakukan untuk mengevaluasi profil estradiol-17β (E2), vitelogenin (Vtg) dalam plasma dan diameter telur pada proses pematangan gonad ikan patin siam (Pangasianodon hypophthalmus). Sampel darah untuk pengukuran konsentrasi E2 dan Vtg plasma diperoleh dari ikan patin siam betina yang belum matang gonad, ikan jantan, ikan betina dengan tahap kematangan gonad yang berbeda (tahap I, II, III dan IV). Perkembangan kematangan gonad ikan patin siam diamati berdasarkan diameter telur. Hasil penelitian menunjukkan bahwa konsentrasi E2 tertinggi (843,65 pg/mL) pada ikan betina dengan kematangan tahap III, terendah pada ikan jantan (26,34 pg/mL), dan ikan betina tidak matang gonad (29,37 pg/mL). Pita protein Vtg pada sampel plasma diperoleh dari betina matang gonad (tahap I, II, III dan IV) dengan berat molekul antara 140-180 kDa, tetapi tidak diperoleh pada ikan patin siam betina yang belum dewasa dan jantan. Nilai konsentrasi tertinggi Vtg ditemukan dalam plasma darah ikan betina dengan tingkat kematangan III (87,34 mg/mL) kemudian pada tahap II (74,83 mg/mL), I (68,58 mg/mL) dan IV (33,45 mg/mL). Hal ini menunjukkan bahwa pada ikan betina dewasa terjadi proses pembentukan kuning telur (vitelogenesis). Rata-rata diameter telur adalah 0,107 ± 0,052 mm, 0,318 ± 0,086 mm, 0,864 ± 0,099 mm dan 1,041 ± 0,058 mm pada tingkat kematangan I, II, III dan IV secara berurutan. Peningkatan nilai diameter telur seiring dengan perkembangan tahap kematangan gonad menunjukkan bahwa perkembangan telur terjadi karena proses vitelogenesis dan penambahan bahan kuning telur pada oosit.

ABSTRACT This study aimed to evaluate the effect of 17α-methyltestosterone hormone (MT) injecting to female broodstocks and stocking densities on the aggressive and cannibalistic behavior of African catfish larvae. Two-day-old post-hatching larvae were used in this experiment. Larval rearing was started at three-day-old post-hatching (body weight 0.004 ± 0.003 g and total length 0.2 ± 0.05 cm) in a 40 cm×30 cm× 25 cm rearing aquaria. This study used a completed randomized factorial design which consisted of two factors. The first factor were the larvae from females broodstocks without MT injection (0 μg/g body weight) (A), injected with MT (1 μg/g body weight) (B), and injected with MT (2 μg/g body weight) (C), while the second factor were larval stocking densities of 3.000/m2 (V1) and 6.000/m2 (V2), with three replications. The results showed that the larvae from female broodstocks injected with MT 2 μg/g body weight (C) and stocking densities 6.000/m2 (V2) increased the aggressiveness of swim and decreased cannibalism. The highest cannibalistic behavior occurred from 00.00‒06.00.Keyword: aggressiveness, cannibalism, Clarias gariepinus, methyltestosterone ABSTRAKPenelitian ini bertujuan untuk mengevaluasi pengaruh hormon 17α-metiltestosteron (MT) yang diinjeksikan pada induk betina dan padat tebar terhadap tingkat agresivitas dan kanibalisme larva ikan lele.

Hatchery managers and maintaining genetic diversity and fitness population in endangered and threatened species in pond is a important and difficult thing to do. But is must to do for conservation biology. Fitness and structure population depends on effective breeding number (Ne) and population connectivity between each other. The second most important thing is gene flow and genetic drift. Ne is major role in the maintenance of genetic diversity as indicator for inbreeding depresion and genetic drift. We sampled 6 hatchery in Jakarta and Bekasi Indonesia region and used 12 polymorphic microsatellite loci to quantify population genetic structure. Result in this study are, each farm have different methode. The old farmers is bapak Gusi and bapak Hasan (+30 years). Ne in bapak Hasan and bapak Gusi hatchery is 66,667 and F value is 0,00749 and loosing allele (P) is 0,26183. Compared with younger farmers bapak Yahya (5 years) have Ne = 133,333, F = 0,00375 and P = 0,06855. Even though hatchery bapak Hasan and bapak Gusi have the same value Ne, F and P but the result in population structure they are different founder populations. Hatchery bapak Hasan have unique structure and alleles composition compared with other hatchery.Keywords: breeding, management, Melanotaenia boesemani, hatchery, population.

In the last decade, the research community has devoted significant attention to wireless sensor networks (WSNs) because they contribute positively to some critical issues encountered in nature and even in industry. On the other hand, localization is one of the most important parts of WSN. Hence, the conception of an efficient method of localization has become a hot research topic. Lastly, it has been invented, a set of optimal positioning methods that make locate a node with low cost and give precise results. In our contribution, we investigate the source of imprecision in the distance vectorhop (DVHOP) localization algorithm. However, we found the last step of DVHOP caused an imprecision in the calculation. Consequently, our work was to replace this step, aiming to reach satisfactory precision. For that purpose, we created three improved versions of this algorithm by adopting two meta-heuristic (simulated annealing, particle swarm optimization) and Fmincon solver dedicated to optimization in the field of WSN node localization. The experimental results obtained in this work prove the efficiency of simulated annealing (SA)-DVHOP in terms of accuracy. Furthermore, the enhanced algorithm outperforms its opponents by varying the percentage of anchors and the number of nodes.

This study aimed to track maternal testosterone hormone in catfish (Clarias gariepinus) eggs as an endogenous factor causing cannibalism. The fish used were female catfish broodstocks that had never been spawned before, with an average weight of 450.0±62.00 g and a total length of 35.4±3.53 cm. The male broodstock had an average weight of 810.0±85.00 g and a total length of 46.1±5.83 cm. The broodstock were maintained separately by sex in 3×1×1 m3 hapa nets, with a stocking density of two females and one male (2:1 ratio). The study employed a completely randomized design (CRD) with treatments consisting of females injected with propylene glycol (0 µg/L body weight) (A), females injected with the hormone 17α-MT (1 µg/L body weight) (B), and females injected with the hormone 17α-MT (2 µg/L body weight) (C), each treatment replicated three times. For the observation of hormone derivatives, egg samples were collected during the pre-spawning (day 90) and post-spawning (day 91) periods. The results indicated that the testosterone levels in the catfish eggs were higher during the pre-spawning period (A: 0.6±0.03 ng/mL; B: 0.7±0.07 ng/mL; C: 1.2±0.01 ng/mL) compared to the post-spawning period (A: 0.3±0.03 ng/mL; B: 0.1±0.00 ng/mL; C: not detected). This finding suggests that, even without the injection of the 17α-MT hormone, testosterone is present in catfish eggs, albeit in small amounts.Keywords: Aggressiveness, cannibalism, inherited hormones.

Perilaku kanibal pada benih ikan baung (Hemibagrus nemurus) menjadi permasalahan pada pembenihannya. Salah satu pendekatan yang sudah dilakukan untuk mengendalikan kanibalisme pada ikan adalah pemberian triptofan. Penelitian ini bertujuan untuk mengetahui pengaruh triptofan terhadap kejadian kanibalisme dan kandungan konsentrasi hormon steroid pada benih ikan baung. Panjang awal benih yang digunakan adalah 4,98±0,1 cm yang dipelihara di dalam akuarium berkapasitas 20 L dengan kepadatan 3 ekor per L. Selama penelitian, benih ikan baung diberi pakan komersial (40% protein) yang disuplementasi triptofan dengan konsentrasi berbeda, yaitu tanpa suplementasi triptofan (A), suplementasi triptofan 0,25% (B), suplementasi triptofan 0,50% (C), suplementasi triptofan 0,75% (D), dan suplementasi triptofan 1% (E). Setiap perlakuan terdiri dari tiga kali ulangan. Pakan diberikan empat kali sehari secara satiasi. Parameter yang diamati adalah tipe kanibal, indeks kanibal, kematian normal, sintasan, performa pertumbuhan serta konsentrasi hormon (estradiol, testosteron, dan kortisol). Hasil penelitian menunjukkan bahwa pemberian pakan yang diperkaya triptofan memberikan penurunan kejadian kanibal dan peningkatan sintasan benih ikan baung. Pemberian triptofan juga menurunkan kandungan estradiol tubuh, dan penurunan ini ada kaitannya dengan penurunan kejadian kanibalisme. Performa pertumbuhan benih ikan baung meningkat dengan pemberian pakan yang ditambahkan triptofan. Hasil penelitian ini menunjukkan bahwa suplementasi 0,50–0,75% triptofan pada pakan efektif menurunkan kejadian kanibalisme pada benih ikan baung.The cannibal behavior of Asian redtail catfish (Hemibagrus nemurus) is a problem in the hatchery. One approach that has been used to control cannibalism in fish is the use of tryptophan. This study aimed to determine the effect of tryptophan on the incidence of cannibalism and the content of steroid hormones in Asian redtail catfish juveniles. The study was conducted using the fish with a body length of 4.98±0.14 cm reared in aquariums with a water volume of 20 L with a density of 3 fish per L. Fish were given commercial feed (40% protein) supplemented with tryptophan with different concentrations, namely without tryptophan supplementation (A), tryptophan supplementation 0.25% (B), tryptophan supplementation 0.5% (C), tryptophan supplementation 0.75% (D), and tryptophan supplementation 1% (E). Each treatment consisted of three replications. Feed were given four times a day at satiation level. Parameters observed were cannibal type, cannibal index, normal mortality, survival rate, growth performance, and hormone concentration (estradiol, testosterone, and cortisol). The results showed that giving tryptophan through feed decreased the incidence of cannibalism and increased the survival of Asian redtail catfish juveniles. The addition of tryptophan to the feed decreased the concentration of estradiol in the body of fish and it is associated with a decrease in the incidence of cannibalism, thereby improving survival. Furthermore, the supplementation of tryptophan also increased growth performance. The results of this study showed that supplementation of 0.50-0.75% tryptophan in feed was effective in reducing the incidence of cannibals in Asian redtail catfish juveniles.

Insulin merupakan hormon peptida yang berperan sangat penting dalam proses metabolisme. Percobaan ini bertujuan untuk mengukur pengaruh pemberian insulin terhadap kondisi, metabolisme dan konsumsi oksigen ikan mas koki melalui penghitungan frekuensi gerakan sirip dada, mulut dan operkulum. Ikan uji yang digunakan adalah ikan mas koki dengan bobot rata-rata 5,26 ± 0,27 g dan panjang rata-rata 8,11 ± 1,45 cm. Penelitian terdiri dari tiga percobaan yang meliputi (1) pergerakan pada ikan yang diberi insulin dilanjutkan dengan penambahan larutan gula, (2) pergerakan pada ikan yang diberi larutan gula kemudian diinjeksi dengan atau tanpa insulin, (3) pergerakan pada ikan pada suhu rendah diikuti dengan diinjeksi insulin lalu pemberian larutan gula. Pemberian insulin baik yang pada media pemeliharaan maupun melalui injeksi meningkatkan frekuensi gerakan mulut dan operkulum yang mengindikasikan bahwa insulin meningkatkan laju metabolisme dan konsumsi oksigen ikan. Suhu media yang rendah menurunkan semua pergerakan ikan, namun pemberian insulin dapat mengembalikan aktivitas ikan menjadi seperti pada suhu normal. Dari hasil penelitian ini dapat disimpulkan bahwa pemberian insulin dan larutan gula berpengaruh secara nyata pada tingkah laku ikan, laju metabolisme dan konsumsi oksigen pada ikan mas koki.
