The aim of this study were to know growth and gonadal development of tetraploidy common carp. The method that used in this study was experiment. Treatment that used was tetraploidyzation by heat shock 40°C during 1.5 minutes of common carp eggs to 29 minutes after fertilization. Five replicates were carried out for treatment. Parameters test were relative length growth (h), specific growth rate (SGR) and gonadal development of common carp. Data analysis that used was descriptive analysis. The result of this study indicated that tetraploidization teratment influenced on growth and gonadal development of common carp. The relative length growth of tetraploidy common carp was 5.38 ± 0.12 (30-days) and 19.12 ± 0.00 (110-days), as their specific growth rate was 19.87 ± 0.10 percent BW/day (30-days) and 8.57 ± 0.00 percent BW/day (110-days). Tetraploidy common carp have fertile characteristic and show gonadal development that same with diploid common carp relatively.

ABSTRAKIkan nila merupakan salah satu jenis ikan bernilai ekonomis tinggi dan banyak dikonsumsi masyarakat. Sehubungan dengan hal tersebut, perlu dilakukan rekayasa budidaya untuk memenuhi kebutuhan dan permintaan masyarakat. Penelitian ini bertujuan untuk mengetahui pengaruh lama waktu perendaman tiroksin dan mengetahui lama waktu perendaman tiroksin yang terbaik digunakan untuk memacu pertumbuhan dan kelulushidupan larva nila putih. Penelitian ini dilaksanakan di Balai Benih Ikan Siwarak (BBI) Ungaran, Semarang, Jawa Tengah, pada bulan Oktober-November 2018. Ikan uji yang digunakan adalah larva ikan nila putih yang telah lepas kuning telur. Pemeliharaan dilakukan selama 35 hari. Penelitian ini menggunakan 4 perlakuan dan 3 ulangan yaitu A direndam tiroksin 0,1 mg/L selama 0 menit (kontrol), B direndam tiroksin 0,1 mg/L selama 12 jam, C direndam tiroksin 0,1 mg/L selama 24 jam, D direndam tiroksin 0,1 mg/L selama 36 jam. Variabel yang diukur meliputi, pertumbuhan bobot mutlak, pertumbuhan panjang mutlak, laju pertumbuhan spesifik, kelulushidupan, dan kualitas air. Nilai terbaik pertumbuhan bobot mutlak adalah C 1,05±0,21g. Nilai terbaik laju pertumbuhan spesifik adalah C 10,20±0,54%/hari. Nilai terbaik pertumbuhan panjang mutlak adalah C 36,03±2,59cm. Nilai terbaik kelulushidupan adalah B 92,22±0,96% tetapi tidak berpengaruh nyata terhadap semua perlakuan. Dengan demikian lama waktu perendaman tiroksin berpengaruh nyata terhadap pertumbuhan bobot mutlak, laju pertumbuhan spesifik, dan pertumbuhan panjang mutlak larva nila putih namun tidak berpengaruh nyata terhadap tingkat kelulushidupan larva nila putih. Lama waktu perendaman terbaik untuk meningkatkan pertumbuhan dan kelulushidupan larva nila putih adalah 24 jam.Kata kunci : Lama Waktu Perendaman; Tiroksin; Pertumbuhan; Kelulushidupan; Nila PutihABSTRACT Tilapia fish is one kind fish of high economical value and widely consumed by society. In this regard, cultivation needs to be done to meet the demands and demands of the community. The study aims to determine the long-term influence of thyroxine and the long-time immersion of thyroxine is best used to spur the growth and livelihoods of white tilapia larvae. This research was conducted in the Siwarak Fish Seed Hall (BBI) Ungaran, Semarang, Central Java, in October-November 2018. The test fish used are white tilapia larvae that have loose egg yolks. Maintenance is done for 35 days. This study uses 4 treatments and 3 repeats ie A soaked thyroxine 0.1 mg/L for 0 hours (control), B soaked thyroxine 0.1 mg/L for 12 hours, C soaked thyroxine 0.1 mg/L for 24 h, D soaked thyroxine 0.1 mg/L for 36 hours. The variables measured include, absolute weight growth, absolute length growth, specific growth rate, sustainability, and water quality. The best value of absolute weight growth is C 1.05 ± 0, 21g. The best value of the specific growth rate is C 10,20 ± 0.54%/day. Best value of absolute length growth is C 36,03 ± 2, 59cm. The best value of a livelihood is B 92,22 ± 0.96% but has no real effect on all treatment. Thus a long time the immersion of thyroxine has a noticeable effect on absolute weight growth, specific growth rate, and the absolute long growth of white tilapia larvae but does not affect the degree of livelihood of white tilapia larva. The length of the best soaking time to improve the growth and livelihoods of white tilapia larvae is 24 hours.Key words: Immersion Time; Thyroxine; Growth; Survival; White Tilapia

Abstract The growth of betutu classified slow, so do efforts in order that growth of betutu which protected optimal by choosing the exact food combination. This research is purpose to know the growth fingerlings of betutu. This research using complete random program giving 3 repeated by the way of treating P1 (food 100% pelet), P2 (food 100% Daphnia spp.), P3 (food 100% Tubifex sp.), P4 (food 100% Anadara granosa), P5 (food combination 50% pelet and 50% Daphnia spp.), P6 (food combination 50% pelet and 50% Tubifex sp.), P7 (food combination 50% Anadara granosa and 50% Daphnia spp.), P8 (food combination 50% Anadara granosa and 50% Tubifex sp.). Main test parameter checked on this research is growth (accretion weight), growth rate, specific growth rate, and absolute body length growth, while supporting test parameter is water quality. Data of growth analysis using ANAVA (varian analysis) and if there is the influence the way of treating so continued with Test of Multiple Gap Duncan by trusty degree 95%. The result of research show the growth (accretion weight), growth rate, specific growth rate and the best absolute body length growth on the way of treating P6 which not different with the way of treating P3 and P8.

<p>The aim of this study was to know effects of honey supplementation in female brood feed on male and female percentages, growth, and survival rate of crayfish red claw seed. The method that used in this study was laboratory scale experiment. The treatments that was applied were addition of honey dosages in female brood feed of crayfish red claw, i.e. 0 (control), 50, 100, 150, 200, 250 and 300 ml/kg feed. Parameters test were male and female percentages, daily growth (G), specific growth rate (SGR) and survival rate of crayfish red claw seed. Data analysis that used was descriptive analysis. The result of this study indicated that supplement of honey in female brood feed of crayfish red claw influenced male and female percentages, growth rate, and survival rate of seed. Treatment of honey dosage 300 ml/kg feed has high result, i.e. male percentage was 58,09% (female, 41.09%), daily  growth was 0.59 mm/day, specific growth rate was 0.10% of BW/day, and survival rate was 96.77 %. Treatment of honey dosage 0 ml/kg feed (control) showed low result, i.e. male percentage was 46.72 % (female, 53.28%), day growth was 0.55 mm/day, specific growth rate was 0.01%  of BW/day, and survival rate was 94.74%.</p> <h3>Keywords: supplementation, honey, crayfish, sex, growth</h3> <p> </p> <h3>ABSTRAK</h3> <p>Tujuan penelitian ini adalah untuk mengetahui pengaruh suplementasi madu dalam pakan induk betina terhadap persentase jantan dan betina, pertumbuhan dan kelangsungan hidup benih lobster air tawar <em>red claw</em>.

The feed must have a quality that matches the needs of the fish to produce high fish growth. Feed quality can be improved by adding alternative ingredients to feed. One alternative material that can be used is papaya leaves. The purpose of this study was to determine the effect of adding papaya leaves to feed on the growth of catfish (Clarias sp). This research was conducted in Muara Enim, South Sumatra in August 2020. The treatments were P0: control (without adding papaya leaves) and P1: with the addition of papaya leaves. The data observed included absolute growth, specific growth rate, feed efficiency, and survival. Fish maintenance data that obtained in treatment P0, that absolute weight growth of 8.43 g, absolute length growth 5.13 cm, specific growth rate 6.41 %, feed efficiency 95.77 %, and survival 76 %, while in P1 treatment using leaves papaya produced absolute weight growth of 10.57 g, absolute length growth of 5.17 cm, the specific growth rate of 5.84 %, feed efficiency 100.83 %, and survival 60 %. The results obtained indicate that the provision of papaya leaves affects the growth of catfish.
