The research is aimed to know the supplementation effect of different concentration of Spirulina platensis fluor on artificial feed against the growth and feed efficiency of goldfish. The experimental research was carried out on September 2018 until April 2019 at The Fisheries Laboratory, Djuanda University, Bogor. The experimental research used completely randomized design with 4 treatments and each 3 replications. The treatments are K (Control, without supplementation of Spirulina platensis fluor), A (30 g of Spirulina platensis fluor + 1 kg  of artificial feed), B (60 g of Spirulina platensis fluor + 1 kg  of artificial feed), and C (90 g of Spirulina platensis fluor + 1 kg  of artificial feed). The total length growth, the weight growth, feed efficiency, and water quality (temperature, pH, dissolved oxygen, and NH3) had been evaluated.  The results of research showed there was  a significantly different between treatments for the growth and feed efficiency (P<0.05).  The best results were obtained in treatment B with an average total length growth of 2.19 cm, average weight growth of 1.51 g, and average feed efficiency of 30.26%. Water quality during the research are temperaure of 25.6-27.5oC, pH of 7.2-8.3,  DO of 6.2-7.1 mg/L, and NH3 of 0.01-0.30 mg/L.Key words : Goldfish, Spirulina platensis, growth, feed efficiency

Riyadhi et al, 2019. The Using of Water Jasmine (Echinodorus palaefolius) as Biological Filter on Angelfish (Pterophyllum scalare)  Rearing. JLSO 8(1):67-76. Water quality was one factors that become a contraint in ornamentalfish culture. This study aimed to compare the result of  jasmine water as a biological filter in maintaining water quality and reducing organic matter in the rearing of angelfish with a recirculation system. This research was conducted for 28 days at the Basic Laboratory of  Aquaculture, Departement of aquaculture, Universitas Sriwijaya. The research Used a completely randomized design with 5 treatments and 3 replications. The results showed that water quality  of  the temperature, pH, dissolved oxygen, ammonia, nitrat and  phosphate values was (27.2-29.2ºC), (5.7-6.9), (4.68-5.74 mgL-1), (0.005-0.037 mgL-1), (0,06-0,12 mgL-1) and ( 0.013-0.107 mgL-1). In treatment P0 the lowest fish survival was 44.45%, absolute length growth was 1.56 ± 0.26 cm, absolute weight growth was 1.47 ± 0.34 g, feed efficiency was 40,54 ± 2,54. While in treatment P4 the highest survival was 72.22%, absolute length growth was 1.24 ± 0.17, absolute weight growth was 1.25 ± 0.24 g feed efficiency 51.32 ± 13. The survival rate of angelfish in the treatment  without using water jasmine showed the lowest percentage of survival compared to other treatment.

This research is aimed to determine the influence of denisity of catfish (Clarias gariepinus) on the recirculation system. Fish test used is catfish fry the age of 2 weeks with average weight 0.58 g and an average length of 2.7 cm as much as 10,000 fish. The experimental research used completely randomized design with 4 treatments and 3 replications. The treatments were A (20 fish/liter of water), B (30 fish/liter of water), C (40 fish/liter of water) and D (50 fish/liter of water). The survival rate, the feed efficiency, and water quality has been observed. The results of research showed that the survival rate and the feed efficiency were significantly different (P<0.05). The highest survival rate in this research was in the treatment A (20 fish/liter of water) that was 70.5%. The stocking density of catfish fry of 20 fish/liter of water can be used as basis for  the maintenance of catfish fry for reach the optimal survival rate. Key words: Catfish, survival rate, feed efficiency, recirculation

The need to seek for alternative feed materials with nutritional and medicinal values to support livestock growth necessitated this study. Forty-five unsexed rabbits crosses (Chinchilla × Newzealand white) 5- 6 weeks old with average weight of 720g were used in a 10- week feeding trial to evaluate the performance of growing rabbits fed on varying levels of dried okra leaves. The rabbits were assigned into five treatment groups containing dried okra leaves (DOL) at 0%, 2.5%, 5%, 7.5% and 10% inclusion levels for dietary treatments (T1, T2, T3, T4 and T5) respectively. Each treatment consisted of 9 rabbits and replicated thrice with each replicate consisting of 3 rabbits in a completely randomized design. Data collected were subjected to one-way analysis of variance (ANOVA). Results indicated that daily feed intake was significantly (P<0.05) largest in rabbits fed 5.00% inclusion level of dried okra leaves (84.57g) and least in rabbits fed 0.00% level of inclusion of dried okra leaves (72.12g). Feed efficiency (FE) was poorest (P<0.05) in rabbits fed 10.00% DOL (0.15%) and best (0.20%) in rabbits fed 2.50% dried okra leaves. It was concluded that okra leaves can be included in diets for growing rabbits and 2.50% level of dried okra leaves inclusion is recommended for adoption by farmers to maximize profit.

Giant Prawns (Macrobrachium rosenbergii) or freshwater prawn is also one of the crustaceans, which has the largest size compared to other freshwater prawns, in addition to giant prawns have a high economic value. The obstacle to the giant prawn's cultivation is determining the combination of natural and artificial feeding for giant prawns to improve molting quickly and increasing the growth of giant prawns. The method used was the experimental method, Completely Randomized Design (RAL) with five treatments: P1 (100 % Pellet), P2 (25 % Tubifex + 75 % Pellet), P3 (75 % Tubifex + 25 % Pellet), P5 (100 % Tubifex) and 3 replications. The data were analyzed using diversity analysis (ANOVA), and if there were differences it could be continued with the BNT test. The results showed that The Influence of Tubifex sp and Natural Feeding Percentage And Artificial Feeding On Moulting Acceleration And Growing Giant Prawns/Crawfish (Macrobrachium Rosenbergii) Stadia V greatly influenced the molting of giant prawns. The water quality during the study ranged from 23˚C-29˚C, dissolved oxygen 3,6-8,7 mg/l, and pH ranged from 7.3 to 8.9. The conclusions from the 30-days of study obtained the highest results for molting on the second treatment (P2) was 0.43, while the fourth treatment (P4) was the best combination in weight growth with a value 6390,42 mg, and long growth showed that the fourth treatment (P4) also gave the highest result which is 406.75 mg.

This research was conducted in April s / d June 2017 located in Fisheries Laboratory of University Prof. Dr. Hazairin, SH Bengkulu. The design of this study used a Completely Randomized Design with 4 Treatments and 6 repeats. The treatments were (1) = CornCob 157 gram, (2) = Corncob 167 gram, (3) = CornCob 177 gram, (4) = Corncob 187 gram. To know the effect or not done an analysis of variance and continued with a test of the Duncan Multiple Range Test (DMRT) 5% and 1%. The parameters observed were absolute weight, absolute length, feed conversion, feed efficiency, and fish survival. The results showed that giving different feed composition of corn cob feed was a significant effect on absolute weight growth, absolute length, feed conversion, feed efficiency but no significant effect on survival of Tawes (Puntius javanicus). Absolute weight growth, absolute length, feed conversion, and feed efficiency are best found in Treatment P1 = Corncob 157 grams and survival of Tawes (Puntius javanicus) 100%.
