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.

<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.

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 %.

This reasearch has been conducted at The Fisheries Laboratory, Agricultural Faculty, Djuanda University, Bogor, on December 2016 – May 2017. The research is aimed to knowthe best concentration of  Keong Masshell mealto increase the growth rate and survival rate of freshwater lobster. The experimental research used completely randomized design with 4 treatments and 3 replications. The treatments were  K (the commercial shrimp artificial feed), A (the artificial feed with 5% the shell meal of Keong Mas), B the artificial feed with 7% the shell meal of Keong Mas), and C (the artificial feed with 9% the shell meal of Keong Mas). The test shrimp were the freshwater Lobster sized 3.5 – 4.5 cm and was fed at satiation twice a day. The daily growth rate, the feed efficiency, survival rate, and water quality has been observed. The results of research showed there were not a  significantly different between the treatments (P>0.05) against the daily growth rate, the feed efficiency, and survival rate of the freshwater Lobster.The shell meal of Keong Mas could be as a Calcium source. The Keong Mas meal can subtitute 100% fish meal of artificial feed thus could be the alternate standard material of the fish meal of the freshwater Lobster feed.Water quality in aquaculture media still on the range of feasible for the freshwater Lobster culture. Keywords: Freshwater Lobster, Keong Mas, Feed, Growth

The Difference

This study was purposed to determine the optimal dose addition of potassium diformate to commercial feed to increase the growth of giant freshwater shrimp. The method employed in this study was an experimental method, embracing application of a Randomized Block Design (RBD) method. It consists of four treatments and four replications. The treatments was based on the difference of potassium diformate amount in which given to giant freshwater shrimp. The difference of potassium diformate amount was 0% (control), 1%, 3%, and 5%. The sample of study used giant freshwater shrimp with a length of 4 - 6 cm. The samples were obtained from the Giant freshwater Shrimp Breeding Center, Pamarican, West Java Province. The shrimp were kept in 16 nets in a density of 20 shrimps and the size of the net cage is about 1 m3. The parameters observed in this research were daily growth rate, feed efficiency, the relation between length and weight, survival rate (analyzed using ANOVA with p < 0,05), and water quality. The sampling was made every 10 days. The results showed that the addition of potassium diformate by 1% gave the best result of daily growth rate of 1.86% ± 0.60, feed efficiency value of 19% ± 1.91, survival rate of 92% with net profit Rp. 67.160.- and for the length and weight relationship has a value of b> 3 which means that it has positive allometry along with water quality parameters regarded to SNI (Indonesian national standard).

There are obstacles in the aquaculture business that is still often facedbyfarmers, one of the challengesisthe high price of commercial feed. Feed as an energy source for growth is a reasonably high-cost component in production that reaches 40-89 %. In the control of food for efficiency, it could be done by the fasting method. This research was aimedtoanalyze the effect of periodic fastedofgiant prawn (Macrobrachium rosenbergii de Man, 1879) against growth and feed efficiency. This research was conducted at IBAP Installation, Probolinggo District - East Java Province. The experimental method used completely randomized design with five treatments and three replications, such as; P0: feeding without fasting (as control), P1: a-day fasted, a-day feeding, P2: a-day fasted, two-days feeding, P3: a-day fasted, three-day feeding, P4: a-day fasted, four-days feeding, P5: a-day fasted, five-day feeding. The results showed that periodic fasted of M. rosenbergii no significant effect on the daily growth rate, absolute weight growth, and feed efficiency. However, by looking at the rate of growth, thisfasting methodcouldbe used as an alternative to saving feed. The P5 showed the most effective in increasing daily growth rate, absolute weight growth, and effectiveness of giant prawn feeding. The strategy of periodic fasted to increase the production of giant prawns should consider the other supporting factors such as ideal water quality (pH, temperature, and DO), proper stocking density, and feeding periods on schedule.
