<p>This experiment was conducted to study the stocking density effect on growth and survival rate of giant gouramy seed in the aquarium. Fish were stocked at the density of 2.5; 5.0; 7.5 and 10 individual/l with average initial weight and length were 0.013 g and 5.56 mm, respectively. Fish were fed with silkworm (<em>Tubifex</em> sp.) <em>ad libitum</em> in the morning and evening for 22 days of experiment. Aquarium was siphoned and water was changed everyday for maintaining good water quality. Result showed that survival rate remain high in all treatment (93.5 - 95.5%). Increasing stocking density from 2.5 to 10 individual/I did not affect survival rate. On the other hand growth rate and feed efficiency decreased, while fish yield increased. Stocking density of 2,5 individual/l gave  the highest daily growth rate, individual growth rate, growth in length and feed efficiency of 12.94%, 0.0081 g/day, 16.84 mm and 12.51%; respectively. The highest value for fish yield (0,0360 g/l/day) was obtained from stocking density of 10 individual/l</p> <p>Key words: stocking density, seed, survival rate, growth rate, giant gouramy <em>Osphrenemus goramy</em></p> <p> </p> <p>ABSTRAK</p> <p>Keterbatasan pengadaan benih ikan gurame (<em>Osphronemus gourame </em>Lac.) disebabkan oleh tidak seimbangnya jumlah benih yang tersedia dengan kebutuhan usaha pembesaran. Teknik pembenihan yang digunakan sampai saat ini relatif sederhana dengan cara tradisional. Pemeliharaan gurame secara terkontrol di akuarium dapat menjawab tantangan dalam teknologi pembenihan gurame sekaligus sebagai sarana pola budidaya secara bertahap yang sedang berkembang saat ini. Produksi yang tinggi akan dicapai dengan pemeliharaan pada kepadatan yang tinggi. Pada keadaan lingkungan yang baik dan pakan yang mencukupi, peningkatan kepadatan akan disertai dengan peningkatan hasil. Jumlah ikan yang ditebar pada penelitian ini disesuaikan berdasarkan perlakuan yaitu 2,5; 5,0; 7,5 dan 10 ekor/l. Pengamatan terhadap ikan dilakukan sampai hari ke-22. Hasil pengamatan menunjukkan bahwa peningkatan kepadatan 2,5 - 10 ekor/l pada pemeliharaan benih gurame di akuarium mempengaruhi pertumbuhan, hasil dan efisiensi pakan, namun tidak berpengaruh terhadap kelangsungan hidup. Dengan meningkatnya padat penebaran, laju pertumbuhan dan efisiensi pakan semakin menurun, sedangkan hasil (<em>yield</em>) semakin meningkat. Padat penebaran 2,5 ekor/l menghasilkan laju pertumbuhan harian, laju pertumbuhan individu, pertumbuhan panjang mutlak dan efisiensi pakan tertinggi, masing-masing mencapai 12,94 %, 0,0081 g/hari, 16,84 mm dan 12,51 %. Sedangkan nilai tertinggi untuk hasil (<em>yield</em>) sebesar 0,0360 g/l/hari diperoleh pada padat penebaran 10,0 ekor/l.</p> <p>Kata kunci : padat tebar, pembenihan, gurame dan <em>Osphronemus gouramy</em></p>

This research aimed to determine the optimal dosage of potassium diformate addition to commercial feed in order to increase the growth and survival rate of common carp seeds. The method used in this research was experimental in a completely randomized design (CRD) consisting of five treatments and four replications. The treatments used were A (control), B with addition of potassium diformate (0.2%), C (0.3%), D (0.4%), and E (0.5%). For test fish, there were 200 of Common carp seeds with a size of 2-3 cm. The media used was 20 aquariums with a size of 40x30x40 cm3 and a stocking density of 10 individuals/aquarium. The rearing period was 35 days and the amount of feed given was 3% of the fish body weight. The parameters observed included water quality (temperature, pH, and dissolved oxygen) which were observed every 7 days for 35 days. Other parameters  monitored were daily growth rate, survival rate, feed efficiency, and the acidity level of the intestine. The results showed that 0.3% addition of potassium diformate gave the best results with a daily growth rate value of 3.21%, highest survival of 98%, efficiency of feed utilization of 64.83%, and a decrease in intestinal pH which helped the process of protein absorption in the fish body. In conclution, the addition of potassium diformate has good effect on growth and survival rates of common carp.

This study examined the effect of stocking density on growth and survival of tilapia cultured in biofloc technology system. Three different stocking densities cultured in biofloc technology were 6 fish/m3, 8 fish/m3 and 10 fish/m3 for 86 days in triplicate for each treatment. The stocking density of the control lot was 3 fish/m3 cultured without biofloc technology. Initial stocking weight ranged from 2–3 g/fish. The water quality parameters were monitored and regulated in the suitable ranges for biofloc technology and for the growth and development of tilapia. The results showed that specific growth rate of fish cultured at a density of 6 fish/m3 was higher than that in the treatments of 8 fish/m3 and 10 fish/m3 with the average values of 5.72%; 5.62% and 5.43%, respectively, and the specific growth rate of fish in the control treatment was 5.71%. Daily growth rate of fish cultured at a density of 6 fish/m3 was higher than that cultured at densities of 8 fish/m3 and 10 fish/m3 with average values of 3.19 g/day, 2.98 g/day, and 2.55 g/day, respectively; and the daily growth rate of the control treatment was 3.27 g/day. Survival rate of tilapia cultured at densities of 6 fish/m3 and 8 fish/m3 was 100%, whereas survival rate of tilapia cultured at a density of 10 fish/m3 was 95.75%, and it was 88.9% for the control lot. The research results provide a scientific basis to propose tilapia culture technique in biofloc technology in brackish water, with the density of 6–8 fish/m3.

Abstract Red tilapia is kind of freshwater culture fish is quite popular because it has several advantages compared with other types of freshwater fish. To fullfil the demand of red tilapia can be overcome by cultivation. Effort to increase the production of red tilapia is to improve the quality of feed. The purpose of this study was to try the effect of the use of sword bean seed meal on the growth rate, survival rate and feed efficiency of red tilapia. The research method is experimental with completely randomized design (CRD) with five treatments and four replications. The treatments used were: (A) sword beans seed meal at 0% and soybean meal by 50%, (B) 10% sword beans seed meal and 40% soybean meal, (C) 20% sword beans seed meal and 30% soybean meal, (D) 30% sword beans seed meal and 20% soybean meal and (E) 40% sword beans seed meal and 10% soybean meal. The main parameters that measured were growth, survival rate and feed efficiency. Secondary parameters measured were water quality. Analysis of the data using analysis of variance (ANOVA) and to know the difference between treatments using Duncan's Multiple Range Test. Results showed the administration of sword bean seed meal on feed rations provide a significantly different effect (p<0.05) on the growth and feed efficiency but not significantly on survival rate of red tilapia (p>0.05 ). Highest daily growth rate obtained on treatment B on feed containing 10% of sword bean meal (1.20 %) was significantly different than treatment A (1.02 %), C (0.88 %) , D (0.85 %) and E (0.75 %) . Lowest daily growth rate was treatment E that significantly different with treatment A and B but not significantly different with treatments C and D. Highest feed efficiency obtained on treatment B (30.29 %) was not significantly different than treatment A (27.56 %), C (25.95 %) and D (27.78 %). Lowest feed efficiency was treatment E (17.84 %) significantly different than treatment B. Subtitution of sword bean seed meal in feed rations gave result that was not significantly different effect on the level of survival of red tilapia. Water quality of red tilapia rearing media was temperature range between 25-28° C, pH 7-8, dissolved oxygen 2-5 mg/L and ammonia 1.5 to 3.0 mg/L.
