The mean length of the highest relative growth in treatment A(30.56%), and the lowest was in treatment C(30.44%). The highest feed conversion intreatment B (1,55%), and the lowest was intreatment A(0,59%). The highest survival rate in treatment A (93.33%), followed bytreatment B(91.52%), andthe lowest was intreatment C(86.67%). The average opening mouth highest in treatment A(58.849), followed involves theB(54.922), andthe lowest was intreatment C(51.413). Long arowana depleted egg yolksfrom the eggs pots(TBK) toegga bigbody(TBB) is 13days, from TBB to swim egg (TBR) 15 days, and from plain eggs to TBR 14 days, so the totalis 42 days. Water quality during the study ranged between temperature 30-32° C, pH73.77, salinity 0.10 - 0.18 ppt, and ammonia from 0.13 - 0.18mg/l.Based on the analysis of variance (ANOVA) on all treatments only on survival and feed conversion were significantly different, followed by HSD test for survival and Duncan test for feed conversion. Judging from the data is the best overall treatment A with variations of mosquito larvae-bloodworms-mosquito larvae.

Abstract-This

Research aimed to evaluate the reproduction status of snakehead in concrete tank  and in natural swamp aquatic. Seven indicators can be made by knowing the snakehead status indicator reproduction so that breeding manipulation in concrete tank can be done. The seven indicators were gonadosomatic indexs, hevatosomatic indexs, body weight, liver weight, gonade weight, egg diameter, fecundity and estradiol-17β concentrations. Result measurement of the gonadosomatic indexs of the snakehead in natural swamp aquatic show in Agust month was 3,3 ± 0.09 and hevatosomatic indexs was 1,1 ± 0.05 in Agust month. For gonadosomatic indexs and  hevatosomatic indexs in concrete tank in April month was 3.6 ± 0.09 and Januari month was 1.0 ± 0.08, respectively. Result of measurement the fecundity and egg diameter of the snakehead in concrete tank in Pebruary month was 2978.3 ± 7.64 and 1.3 ± 0.00 mm respectively, The fecundity and egg diameter of the snakehead in natural swamp aquatic in Januari month was 3080.0 ± 7.91 and Nopember and December was 1.5 ± 0.04 mm respectively. The estradiol-17β concentration of the snakehead in swamp aquatic show the higest concentration in natural aquatic. Average concentration estradiol-17β in natural aquatic in Juni month was 85.3 ± 9.37 pg/ml until December was 169.2 ± 6.22 pg/ml. In concrete tank from 80.5 ± 5.17 pg/ml in Juli until  118.3 ± 6.78 pg/ml in April. In general it is concluded that the reproduction status of snakehead was similar  between in concrete tank and natural swamp aquatic. Enviroment ”trigger” was the limited factor in finally gonade maturation.

Permasalahan dalam pengelolaan induk ikan sepat siam adalah kurang maksimalnya derajat penetasan telur yang hanya mencapai 80,03 %. Salah satu cara yang dapat dilakukan adalah dengan memperbaiki kualitas telur melalui perbaikan kualitas pakan yang diberikan kepada calon induk ikan sepat dengan penambahan bahan suplemen dan imbuhan pakan. Penelitian ini bertujuan untuk mengetahui respon reproduksi induk betina sepat siam terhadap penambahan bahan suplemen dan imbuhan pakan, seperti: minyak ikan, vitamin E serta ekstrak temulawak. Ikan uji adalah induk betina sepat siam dengan usia minimal 8 bulan dan berada pada tingkat kematangan TKG I atau TKG II. Pakan penelitian yang digunakan ada 3 macam yaitu pakan komersial dengan penambahan minyak sayur (FCO), pakan dengan penambahan minyak ikan dan vitamin E (FOT) dan pakan dengan penambahan minyak ikan, vitamin E serta ekstrak temulawak (FOTG).Hasil menunjukkan bahwa pakan FOT dan FOTG dapat mengasilkan indeks gonadosomatik (IGS), fekunditas, diameter telur, derajat penetasan telur dan survival rate yang lebih baik daripada pakan FCO. Hal ini terjadi diduga karena pengaruh dari penambahan vitamin E yang berfungsi mencegah oksidasi dari asam lemak, sehingga lemak yang ada dapat digunakan sepenuhnya. Akibatnya, kualitas dan kuantitas telur jadi meningkat. Nilai IGS pada semua perlakuan berkisar antara 3,07 – 3,57 %, fekunditas berkisar antara 3.875 – 5.355 butir, diameter telur berkisar antara 0,70 – 0,93 mm, derajat penetasan berkisar antara 78,12 – 89,58 % dan survival rate berkisar antara 51 – 83 % pada semua perlakuan. Pakan dengan penambahan minyak ikan dan vitamin E dapat menghasilkan diameter telur dan survival rate yang lebih baik, sedangkan pakan dengan penambahan minyak ikan, vitamin E serta ekstrak temulawak dapat menghasilkan nilai indeks gonadosomatik (IGS), fekunditas dan derajat penetasan telur yang lebih tinggi.

<p>Penelitian ini dimaksudkan sebagai upaya domestikasi Ikan Betok melalui pemijahan dalam wadah budidaya. Penelitian ini dilakukan di Laboratorium Basah Program Studi Budidaya Perairan Universitas Lambung Mangkurat . Tiga poin utama dalam mendukung keberhasilan pemijahan ikan, yaitu : perkembangan gonad , ovulasi dan pemijahan . Tentu perkembangan panjat bertengger gonad ikan terjadi pada awal musim kemarau puncak musim dan di awal musim hujan atau saat musim hujan , pemijahan terjadi . Keadaan alami ini mencoba untuk diadopsi dalam budidaya kontainer , dengan fashting selama 1 , 2 dan 3 hari dengan tingkat air , 10 , 15 dan 20 cm . Hasilnya adalah waktu yang laten dari 11,7 jam sampai 39 jam , fekunditas antara 5310-7376 butir , diameter telur 0,5 hingga 0,8 mm , tingkat fertilisasi antara 88,2-93,2 persen dan tingkat menetas antara 87 , 0-91,6 persen.</p><p>The study is intended as an attempt domestication through climbing perch spawning in the container cultivation. The research was conducted at the Laboratory of Wetlands Program University Faculty of Fisheries Aquaculture Lambung Mangkurat. Three main points in support of the spawning success of fish, namely: gonadal development, ovulation and spawning. Naturally development climbing perch fish gonads occurred in the early dry season to peak season and at the beginning of the rainy season or during the rainy season, spawning occurred. This natural state is trying to be adopted in the cultivation of container, with fashting for 1, 2 and 3 days with water levels, 10, 15 and 20 cm. The result is a latent time of 11.7 hours to 39 hours, fecundity between 5310 to 7376 grains, egg diameter 0.5 to 0.8 mm, the degree of fertilization between 88.2 to 93.2 percent and the degree of hatching between 87, 0 to 91.6 percent.</p>
