Larval of fighting fish (Betta splendens Regan) requires precise live foods for its growth and survival. In this experiment, fish larvae were fed on either Paramecium + Artemia, Paramecium + Artemia + Tubifex, Paramecium + Moina, or Paramecium + Moina + Tubifex. The fish were fed Paramecium from day-2 till day-7 after hatching. There after, the live food was changed according to the treatments till day-28. Results showed that fish fed on Paramecium + Artemia significantly had the highest total length (12.63 mm) than other treatments (11.86 mm). On the other hand, survival rate of fish had no significant affected by the treatments. Keywords: fighting fish, Betta splendens, Paramecium, Moina, Artemia, Tubifex, larvae ABSTRAK Larva ikan betta (Betta splendens Regan) membutuhkan jenis pakan alami yang tepat bagi kelangsungan hidup dan pertumbuhannya.

This study was performed to determine the efficiency of yolk egg utilization in embryos and larvae, hatching rate, incubation time to hatch, and growth rate of maanvis (Pterophyllum scalare) larvae incubated at room remperature, 27oC, and 30oC. Results of study showed that yolk egg utilization efficiency of embryos and larvae incubated at 30oC was 73.70% and 0,18%, respectively, and no different with that of room and 27oC incubation temperatures. Hatching rate of eggs incubated at 30oC (84.75%) was also same with that of other treatments. However, incubation time to hatch (27.41 hours) was shorter than that of other treatments. The growth rate by length of larvae (2.16%) and survival rate (75.28%) incubated at 30oC was also higher compared with that of other treatments. Thus, in general, optimum temperature for egg hatching and larval rearing of maanvis was 30oC.

Hasil penelitian menunjukkan bahwa nilai efisiensi pemanfaatan kuning telur bila diinkubasi pada suhu 30oCsebesar 73,70% pada fase embrio dan 0,18% pada fase larva, dan tidak berbeda dengan suhu ruang dan 27oC. Demikian juga dengan derajat penetasan telur (84,75%) tidak berbeda dengan perlakuan lainnya. Sementara itu, lama inkubasi telur hingga menetas (27,41 jam) lebih cepat dibandingkan dengan suhu inkubasi perlakuan lainnya. Demikian juga dengan laju pertumbuhan panjang (2,16%) dan kelangsungan hidup larva (75,28%) lebih tinggi dibandingkan dengan perlakuan lainnya. Dengan demikian, secara umum suhu optimal untuk penetasan dan pemeliharaan larva ikan maanvis adalah 30°C. Kata kunci: ikan maanvis, Pterophyllum scalare, kuning telur, larva, embrio, suhu

This study was conducted to determine oxygen consumption level of white shrimp (Litopenaeus vannamei) and the model of oxygen management in intensive culture pond. Shrimp in weight of 5 gram were maintained in 20 liter of water in density 6 tails/container. Water quality was measured every 2 hours for 6 hours. Other experiments were done using shrimp in weight of 8, 10, 12 and 15 gram per tail, in density 4 tails/container. The results of study showed that oxygen consumption levels of white shrimp was higher after feeding than before feeding. Oxygen consumption levels of smaller shrimp were higher than that of bigger shrimp. Regression model of oxygen consumption levels before and after feeding were linear. Correlation between oxygen consumption and shrimp weight reached 92.5%. Keywords: white shrimp, Litopenaeus vannamei, oxygen, respiration, intensive pond ABSTRAK Penelitian ini dilakukan untuk mengetahui tingkat konsumsi oksigen udang vaname (Litopenaeus vannamei) dan model pengelolaan oksigen pada tambak intensif. Udang dengan bobot sekitar 5 gram dimasukkan ke dalam wadah tertutup berukuran 20 liter dengan kepadatan 6 ekor/wadah. Kualitas air diukur setiap 2 jam selama 6 jam. Perlakuan tersebut juga dilakukan pada udang dengan kelompok berat 8, 10, 12 dan 15 gram, dengan kepadatan 4 ekor/wadah. Hasil penelitian menunjukkan bahwa tingkat konsumsi oksigen udang vaname sesudah makan relatif lebih tinggi daripada sebelumnya. Tingkat konsumsi oksigen udang ukuran kecil relatif lebih tinggi daripada yang berukuran lebih besar. Model persamaan regresi tingkat konsumsi oksigen pada udang yang tepat sebelum dan sesudah makan adalah linear. Korelasi antara konsumsi oksigen dengan bobot udang mencapai 92,5%.

Study on white shrimp (Litopenaeus vannamei) production in biocrete pond in different density was performed at PT. Bimasena Segara, Citarate, Sukabumi, West Java. Six ponds were used and devided into 2 groups based the density levels, i.e., 72-73 shrimp/m2 and 93-105 shrimp/m2. Experiment was done for 100 days, including pond preparation. The results of study showed that mean weight of shrimp reared in biocrete pond was ranged from 9.64 to 12.34 gram, survival rate 26.97-99.58%, productivity 3,078-8,340.9 kg/ha, feed quantity 2,084.5-2,870.4 kg and FCR 1.19-2.60.

Black tiger shrimp (Penaeus monodon Fab.) culture is now frequently failed as the fault in pond construction and irrigation system, disease break, and younger fry is stocking into pond. Nursery is a rearing of PL12 to be PL25 at a controlled environmental condition to quickly adapt them on pond condition. Nursery experiment was conducted in cage culture (1x1x1 m) placed in an intensive pond at density of 250, 500, 750 and 1000 PL/m2, for 14 days rearing. The results of study indicated that no different in survival and growth of PL was obtained. Daily growth rate was ranged from 1.10% to 1.53%, while the survival rate was ranged from 86.72-95.60%. Higher production of shrimp fry (867 PL25) was obtained by rearing PL12 at density of 1000 PL/m2. Keywords: black tiger shrimp, Penaeus monodon, fry, rearing density ABSTRAK Usaha udang windu (Penaeus monodon Fab.) saat ini banyak mengalami kegagalan akibat konstruksi tambak dan sistem pengairan yang salah, serangan penyakit, dan umur benih yang terlalu muda untuk pemeliharaan ditambak. Penokolan merupakan pemeliharaan benur pada stadia PL12 menjadi PL25 dalam lingkungan yang relatif terkontrol agar dapat beradaptasi dengan cepat pada lingkungan tambak. Percobaan penokolan dilakukan menggunakan hapa (1x1x1 m) yang dipasang di dalam kolam intensif dengan padat tebar 250, 500, 750 dan 1000 ekor PL/m2, selama 14 hari pemeliharaan. Hasil penelitian menunjukkan bahwa tidak ada perbedaan nyata dalam hal kelangsungan hidup dan pertumbuhannya. Laju pertumbuhan harian udang berkisar antara 1,10% sampai 1,53%, sementara tingkat kelangsungan hidup berkisar 86,72-95,60%. Produksi benih udang (867 PL25) terbanyak diperoleh dengan memelihara PL12 pada kepadatan 1000 ekor PL/m2. Kata kunci: udang windu, Penaeus monodon, tokolan, kepadatan tebar

ABSTRACTManagement of phytoplankton is generally conducted by controlling the concentration of organic matter, fertilization and water exchange. Organic materials are from uneaten feed and excretion of shrimp. By using post facto method it was found four class of phytoplankton in biocrete pond at one cycle rearing of white shrimp (Litopenaeus vannamei). Population at early rearing period was dominated by Bacillariophyceae (50.4%; 13 species) and Cyanophyceae (42.41%; 1 species), followed by Dynophyceae (6.2%; 5 species) and Chlorophyceae (1.3%; 1 species). Increment in phytoplankton density was followed by increment in chlorophyll-a and oxygen from photosynthesis, and productivity was 2132 kg/pond.Keywords: phytoplankton, white shrimp, Litopenaeus vannamei, biocrete pond ABSTRAKPengelolaan fitoplankton umumnya dilakukan dengan mengoptimalkan bahan organik serta pemupukan dan pergantian air. Bahan organik berasal dari pakan buatan yang tidak terkonsumsi (sisa pakan) dan ekskresi dari udang. Dengan menggunakan metode post facto selama satu siklus pemeliharaan udang vaname (Litopenaeus vannamei) pada tambak biocrete diperoleh empat kelas fitoplankton. Dominasi Bacillariophyceae (50,4%; 13 jenis), Cyanophyceae (42,41%; 1 jenis) terjadi pada awal pemeliharaan yang diiukuti oleh Dynophyceae (6,2%; 5 jenis) dan Chlorophyceae (1,3%; 1 jenis). Peningkatan kelimpahan fitoplankton secara keseluruhan diikuti oleh peningkatan kandungan klorofil-a dan oksigen hasil fotosintesis total sehingga produktifitasnya mencapai 2132 kg/petakKata kunci: fitoplankton, udang vaname, Litopenaeus vannamei, tambak biocrete

Quality and quantity of freshwater were important factors in aquaculture. The farmers of neon tetra fish (Paracheriodon innesi) usually rear them in aquarium with simple methods, so that gave low productivity. Increasing density could be increased the production and its continuity and also more efficient in land and water. Rearing of neon tetra with density of 25, 50, 75 and 100 litre-1 in recirculation system were no influence for fish body length, growth of body length and coefficient of variants (p>0,05). But those densities of fish rearing affected survival rate, end density and profit (p0,05), namun berpengaruh nyata terhadap kelangsungan hidup, kepadatan akhir dan keuntungan (p
