ABSTRACTFeed is an element which requires largest cost in fish culture. Inefficient in feeding can reduce profit. In additon, intensive fish culture system requires efficiently the use of area. Generally, not all space in fish cage filled by fish, because of the nature of fish that lives in some particular space on water such as the surface, middle space or bottom. Cyprinus carpio andMacrones sp. was reared with gillnet inside gillnet (cage-cum-cage) and fed commercial diet in dose of 3%, 6%, 9% and 12%. Result show that feeding dose of 6% was an efficien mean by relative growth rate. Growth rate of Cyprinus carpio was about 150.47% and Macrones was 208.87%. Feed efficiency was about 81.89%. Survival rate of Cyprinus carpio was about 91.67% and Macrones was 86.67%. Thus, feeding dose of 6% is recommended for Cyprinus carpio andMacrones in cage-cum-cage culture system.Keywords: growth, Cyprinus carpio,Macrones sp., feeding dose, cage-cum-cage ABSTRAKPakan merupakan komponen yang membutuhkan biaya terbesar dalam usaha budidaya. Penggunaan pakan yang tidak efisiensi dapat mengurangi keuntungan usaha. Selain itu budidaya yang intensif juga menuntut penggunaan ruang gerak ikan yang efisien. Umumnya tidak semua kolom air dalam karamba terisi dengan ikan yang dibudidayakan, karena sifat ikan mendiami bagian tertentu dalam air seperti di permukaan, di pertengahan atau di dasar perairan. Ikan mas dan ikan baung dipelihara dengan jaring di dalam jaring (cage-cum-cage) dan diberi pakan dengan dosis 3%; 6%; 9% dan 12%.

Vitamin C has a function for increasing normal growth, preventing bone annomaly for seed health or reducing stress, accelerating wound recovery and improving immune system against bacterial infection. Enhancement of immune response using immunostimulant had been proven in aquaculture. One of the immunostimulant that had been examined in several fish species was vitamin C. However, the immunostimulatory effect of vitamin C on betok remains to be proven. This study was performed to know the effect of feeding fish by diets containing vitamin C in form of ascorbic acid on growth and immune response of betok in term of stress adaptation. Concentrations of vitamin C tested were 0 (control), 125 mg, 250 mg and 375 mg/kg diet. The results show that supplementation of vitamin C in diet can increase daily growth rate and feed efficiency of betok. Daily growth rate of treated fishes (1.37-1.49%) were higher than that of control (1.14%). Feeding efficiency was also higher in treated fishes (39.73-48.07%) compared to that of control (33.73%). There was no significantly difference in survival rate of treated fish (93.33-96.67%) and control (93.33%). Survival rate of fish reared at 15oC as a stress test was also examined. Results showed that survival rate of fish increases by increasing the level of vitamin C in diet. Number of fish died in stress test was 10 in control, 7 fish in 125 mg/kg, 5 fish in 250 mg/kg and 3 fish in 375 mg/kg. Thus, inclusion of vitamin C in diet improved ability of fish to adapt to an extreme environment condition. Keywords: Vitamin C, ascorbic acid, growth, immune response, Anabas testudineus ABSTRAK Vitamin C berfungsi untuk meningkatkan pertumbuhan normal, mencegah kelainan bentuk tulang untuk kesehatan benih atau mengurangi stress, mempercepat penyembuhan luka dan meningkatkan pertahanan atau kekebalan tubuh melawan infeksi bakteri. Peningkatan respon imun dengan pemberian imunostimulan telah dibuktikan dalam akuakultur. Salah satu immunostimulan yang telah diuji pada beberapa spesies ikan adalah vitamin C. Namun demikian, pengaruh imunostimulatori vitamin C pada ikan betok belum diteliti. Penelitian ini dilakukan untuk mengetahui efek pemberian pakan yang mengandung vitamin C dalam bentuk ascorbic acid terhadap pertumbuhan dan respons imun dalam arti daya tahan terhadap stres pada ikan betok. Dosis vitamin C adalah 0 (kontrol), 125 mg, 250 mg dan 375 mg/kg pakan. Hasil penelitian menunjukkan bahwa penambahan vitamin C dalam pakan dapat meningkatkan laju pertumbuhan harian dan efisiensi pakan pada ikan betok. Laju pertumbuhan harian pada ikan perlakuan (39.73-48.07%) lebih tinggi daripada ikan (33.73%). Kelangsungan hidup ikan tidak berbeda antara perlakuan (93.33-96.67%) dan kontrol (93.33%). Kelangsungan hidup ikan yang dipelihara pada suhu 15oC sebagai uji stress as a stress juga diamati. Hasil penelitian menunjukkan bahwa kelangsungan hidup ikan meningkat dengan meningkatnya kadar C dalam pakan. Jumlah ikan yang mati dalam uji stres adalah 10 pada kontrol, 7 pada perlakuan 125 mg/kg, 5 ekor pada perlakuan 250 mg/kg dan 3 ekor pada perlakuan 375 mg/kg. Dengan demikian, penambahan vitamin C dalam pakan meningkatkan kemampuan ikan beradaptasi terhadap kondisi lingkungan esktrim.

Fish requires essential fatty acid for growth. Freshwater fish needs linoleat fatty acid (n-6) or combination of linoleat and a-linolenat acids (n-3). Fish oil contains higher level of n-3, corn oil is rich of n-6, while coconut oil is rich of saturated fatty acids. This study was conducted to determine the effect of fatty acid sources in diet on growth performance of botia Botia macracanthus. Sources of fatty acid examined were coconut oil (control), corn oil, fish oil, and corn oil + fish oil + coconut oil. The results of study show that daily growth rate of fish fed on diet containing mix of corn-coconut-fish oils (8.39%) and only corn oil (8.15%) was higher (p
