ABSTRACT The growth rate between male and female red tilapia Oreochromis sp. is different. Generally, the male red tilapia grows faster than the female. Furthermore, the maturation process of red tilapia is relatively fast which causes slower growth rate. One of solutions to this problem is by rearing all male population or mono-sex culture. The method used in this study was commercial feed enrichment with 17α-methyltestosterone at different dosages and water temperature manipulation. The purpose of this research was to examine the effects of commercial feed enrichment with different dosages of 17α-methyltestosterone and water temperature manipulation on success rate of sex reversal of red tilapia into all male population. This research consisted of different temperature treatments (with and without water heating) and 17α- methyltestosterone dosages (0, 10, 20 mg/kg of commercial feed). The best dosage of 17α-methyltestosterone was 20 mg/kg of commercial feed with male to female sex ratio of 86.31%, daily growth rate of 8.18%, and feed conversion ratio of 1.53. In this study, the best treatment to produce the male seeds was the 17α-methyltestosterone treatment. Keywords: 17α-methyltestosterone, sex reversal, red tilapia, temperature ABSTRAK Ikan nila merah Oreochromis sp. memiliki laju pertumbuhan yang berbeda antara ikan jantan dan betina. Umumnya ikan nila merah jantan lebih cepat tumbuh dibandingkan betinanya. Selain itu, ikan nila memiliki sifat cepat matang gonad dan mudah memijah sehingga akan menghambat pertumbuhan ikan. Salah satu cara untuk mengurangi masalah yang terjadi yakni dengan memelihara populasi ikan nila merah tunggal kelamin atau monoseks jantan. Metode yang dilakukan adalah pemberian hormon 17α-metiltestosteron dengan dosis berbeda melalui pakan buatan dan peningkatan suhu air. Penelitian ini bertujuan untuk mengetahui pengaruh dosis hormon 17α-metiltestosteron melalui pakan buatan dan peningkatan suhu air terhadap keberhasilan alih kelamin jantan pada ikan nila merah. Penelitian ini terdiri atas perlakuan suhu (dengan dan tanpa pemanasan air) dan dosis 17α-metiltestosteron (0, 10, 20 mg/kg pakan). Dosis hormon 17α-metiltestosteron terbaik yang didapatkan adalah 20 mg/kg pakan dengan nisbah kelamin jantan 86,31%, laju pertumbuhan harian 8,18%, dan rasio konversi pakan 1,53. Pada penelitian ini perlakuan terbaik untuk menghasilkan benih jantan adalah perlakuan dosis 17α-metiltestosteron. Kata kunci: 17α-metiltestosteron, alih kelamin, ikan nila merah, suhu

ABSTRACT This study was conducted to evaluate reproduction of broodstock and intraspecific hybrid juvenile performance of Egyptian (M) and sangkuriang (S) strain African catfish Clarias gariepinus at nursery phase. Intraspecific hybridization of African catfish was carried out reciprocally (SM and MS) and purebreed (SS and MM), each was with three replicates. Fish spawning was conducted by artificial fertilization, and larvae were reared at 1st, 2nd and 3rd nursery phases, subsequently. The results showed that broodstock performance (male and female) of both strains were not significantly different (P>0.05) on all reproduction traits, except female’s gonadosomatic index. Fertilization and hatching rates of all hybrids were not significantly different (P>0.05). MM juvenile had higher growth performances than other juvenile hybrids. Heterosis of total length, standard length, and body weight were varied, whereas the survival showed positive heterosis. SM juvenile showed positive growth heterosis in 3rd nursery phase (total length, standard length, and body weight were 2.61%; 2.16%, and 4.79% respectively). Survival heterosis of MS juvenile (24.20% for total length; 103.13% for standard length and 11.62% body weight) was higher than SM juvenile (6.86%; 48.57%, and 3.09%) on all nursery phases Keywords: African catfish, intraspecific hybridization, growth, survival, heterosis ABSTRAK Penelitian ini dilakukan untuk menguji performa reproduksi induk dan benih hasil hibridisasi intraspesifik ikan lele Afrika Clarias gariepinus strain Sangkuriang (S) dan Mesir (M) pada fase pendederan.

Tilapia fish farming using monosex male population has been reported to have 10% higher productivity compared to mix-sex culture. This study aimed to determine immersion dose of 17α-metiltestosterone (MT) that allowed higher male percentage, growth, survival, and measure testosterone level in fish body. The experiment was designed as three immersion doses, namely: 0; 1.8; and 5.4 mg/L MT, each with three replications. Immersion was conducted to 14-day-old larvae for four hours, with density of 100 fish/L of water. Testosterone levels in fish was measured using ELISA method, and sex identification was performed by histology method. The result showed that percentage of male fish was the same in the treatment of 1.8 mg/L and 5.4 mg/L, and 53–65% higher than the control without MT treatment (54% male). Growth and survival of fish until day 56 post immersion were the same. By ELISA analysis, the levels of testosterone in larvae just after immersion was similar in 1.8 mg/L and 5.4 mg/L treatments, decreased drastically on day 14 after immersion, and then the levels of testosterone to be similar with the control on day 28, i.e. about 2 ng/g. By PCR method with specific primer, sex reversed and normal males could be distinguished, and on day 71 the testosterone levels in sex reversed and normal males fish was also the same, 0.3 ng/g (P>0.05). Thus, sex reversal by immersion at a dose of 1.8 mg/L can be consider as a standard protocol for monosex tilapia production. Testosterone level in the body of MT-treated fish becomes the same to the control of less than one month post immersion

ABSTRACT Immersion of undifferentiated larval tilapia in high temperature and 17α-methyltestosterone (MT) cab increase the male ratio. However, the effectiveness of immersion in high temperature of water containing MT remains to be evaluated. The purposes of this study were: 1) evaluate the male ratio, growth, and survival of tilapia, and 2) analyze the aromatase brain-type gene expression level in tilapia after immersing in high temperature (36 °C) containing MT at 2 mg/L for four hour with single and double immersion. Aromatase gene expression was analyzed by semi-quantitative RT-PCR (sqRT-PCR) method. The result showed that higher monosex male ratio was obtained by single immersion of MT at 36 °C at room temperature. Gene expression level of aromatase brain-type was lower on single immersion and increased significantly at second immersion compared to control (immersion at room temperature without MT). Immersion using MT and high temperature had no significant effect on fish survival. However the specific growth rate and fish biomass were higher than control. Thus, monosex male tilapia can be produced by single immersion of undifferentiated larvae at 36 °C temperature containing MT. Keywords: male ratio, aromatase, Oreochromis niloticus, temperature, 17α-methyltestosterone ABSTRAK Perendaman larva ikan nila yang belum terdeferensiasi kelaminnya dengan suhu tinggi dan hormon 17α-metiltestosteron (MT) dapat meningkatkan nisbah kelamin jantan. Tetapi, efektivitas perendaman menggunakan MT pada suhu tinggi belum diteliti. Tujuan dari penelitian ini adalah 1) mengevaluasi nisbah kelamin jantan, pertumbuhan, dan kelangsungan hidup ikan nila, dan 2) menganalisis ekspresi gen aromatase tipe-otak pada ikan direndam menggunakan MT dengan dosis 2 mg/L selama empat jam sebanyak satu dan dua kali perendaman pada suhu 36 °C. Ekspresi gen aromatase dianalisis menggunakan metode RT-PCR semi-kuantitatif (sqRT-PCR). Hasil penelitian menunjukkan bahwa kombinasi perendaman MT satu kali pada suhu 36 °C lebih tinggi menghasilkan ikan nila jantan monoseks dibandingkan perendaman MT satu kali pada suhu ruang. Tingkat ekspresi gen aromatase tipe otak pada perendaman satu kali lebih rendah, dan meningkat secara signifikan pada perendaman kedua dibandingkan dengan kontrol (perendaman pada suhu ruang tanpa MT). Perendaman larva menggunakan MT dan suhu 36 °C tidak berpengaruh nyata terhadap kelangsungan hidup, tetapi laju pertumbuhan spesifik dan biomassa ikan perlakuan tersebut lebih tinggi daripada kontrol. Dengan demikian, ikan nila jantan monoseks dapat diproduksi dengan perendaman satu kali pada larva yang belum terdeferensiasi jenis kelaminnya menggunakan MT pada suhu 36 °C.

ABSTRACTThis study was conducted to evaluate stress responses of transportation on red tilapia Oreochromis sp. which given feed containing chromium. Three isonitrogenous and isocaloric experimental feeds were prepared, these diets were control (without chromium), CrPic 1 mg/kg, and CrYst 2 mg/kg supplementation in feed, all group were arranged triplicate. Satiation feeding was done three times a day. After a 60-day feeding experiment, the experimental fishes were fasted and distributed in polyethylene bags (N=60 fish/bag) containing 3 L of water, subjected to condition of transport simulation for 13 hours. Survival rate, levels of plasma cortisol, blood glucose, superoxide dismutase (SOD), and malondialdehyde (MDA) enzyme were observed at before transportation, after transportation, one day, and two days after transportation. The result showed that chromium supplementation reduced the levels of plasma cortisol before and after transportation, one day, and two days after transportation. Also, it decreased blood glucose compared with control significantly before transportation and one day after transportation. The SOD enzyme concentration increased significantly after fish was fed with feed containing chromium for 30 days, while the MDA enzyme concentration increased significantly after two days of transportation. However, there was no significant difference in the survival of red tilapia between treatments. The best result was obtained in the treatment of fish which fed with feed containing chromium. CrPic supplementation 1 mg/kg and CrYst 2 mg/kg increased the body resistance in red tilapia by decreasing the negative effect of stress while transportation. Keywords: stress, transportation, red tilapia, chromium ABSTRAKPenelitian dilakukan untuk mengevaluasi respons stres transportasi ikan nila merah Oreochromis sp. yang diberikan pakan yang mengandung kromium. Pada penelitian ini digunakan tiga jenis pakan, terdiri atas pakan tanpa suplementasi kromium (kontrol), pakan bersuplementasi kromium pikolinat (CrPic 1 mg/kg), dan kromium yeast (CrYst 2 mg/kg), semua perlakuan diulang sebanyak tiga ulangan. Pemberian pakan sebanyak tiga kali sehari dan dilakukan secara at satiation. Setelah 30 hari pemeliharaan, ikan uji dipuasakan dan didistribusikan dalam plastik polietilen (N=60 ekor ikan/kantong plastik) yang berisi 3 L air, dilakukan dengan simulasi transportasi selama 13 jam. Parameter yang diamati pada penelitian ini adalah kelangsungan hidup, kortisol, glukosa darah, enzim superoksida dismustase (SOD), dan malondialdehida (MDA) saat sebelum transportasi, sesaat setelah transportasi, sehari, dan dua hari setelah transportasi. Hasil yang didapatkan adalah suplementasi kromium menurunkan konsentrasi kortisol secara signifikan sebelum transportasi, sesaat, sehari, dan dua hari setelah transportasi. Suplementasi kromium menurunkan glukosa darah secara signifikan pada saat sebelum transportasi dan sehari setelah transportasi. Konsentrasi enzim SOD meningkat secara signifikan setelah pemberian pakan bersuplementasi kromium selama 30 hari, sedangkan konsentrasi enzim MDA meningkat secara signifikan setelah dua hari transportasi pada ikan yang diberi pakan bersuplementasi kromium. Namun, tidak ada perbedaan yang signifikan pada kelangsungan hidup ikan nila merah antarperlakuan. Hasil terbaik diperoleh pada perlakuan ikan dengan suplementasi kromium. Suplementasi 1 mg/kg CrPic dan 2 mg/kg CrYst dapat meningkatkan daya tahan tubuh pada budidaya ikan nila merah dengan menurunkan pengaruh negatif stres akibat transportasi.
