    This study aims to determine the striped catfish production intensive cultivation reviewed from parameters of water quality pond with a red-yellow podzolic in different ages. The method used in this study is the experimental method using a completely randomized design (CRD) using 1 factor, 4 levels of treatment and 3 replications, , with the treatment are: P1 (intensive pond of catfish aquaculture aged 0-5 years), P2 (intensive pond of catfish aquaculture aged 6-10 years), P3 (intensive pond of catfish aquaculture aged 11-15 years) and P4 (intensive pond of catfish aquaculture aged 16-20 years). The results showed that the striped catfish production in P4 (pond aged 16-20 years) is the best treatment which has a high production of 6.4 kg/m2, with the survival rate of 66,7% and low feed conversion ratio of 1.9%, and supported by water quality parameters were classified as good, namely: temperature between 27,600C, the brightness of 24.03 cm, 6.4 to 7.3 of pH, 3.74 mg/L of oxygen demand, ammonia of 0.21 mg/L, orthophosphate 1.05 mg/L, nitrate 1.03 mg/L, alkalinity total 100.5 mg/L, free carbon dioxide of 9.49 mg/L, and total organic material of 7.23 mg/L. Parameter water quality is relatively good for striped catfish farming

    This research was conducted from March to April 2014, for 30 days in Aquaculture circle Quality Laboratory Unit of Fisheries Faculty and Marine Sciences, University of Riau Pekanbaru. The aims of research was to investigate zeolite absorption toward ammonia and it effects water quality by recirculation system to rear of river catfish (Mystus nemurus). The methods used was experiment with 4 treatment and 3 replications. The treatments were P0= control, P1= Dosis 45,48 g/12 litres atau 3,79 g/litres, P2= Dosis 90,96 g/12 litres atau 7,58 g/litres, dan P= Dosis 136,44 g/12 litres atau 11,37 g/litres. The best treatment is P3, the result show that the more zeolit dose so many ammonia absorption. Water parameters recorded as follows pH (5-6 mg/L ), temp (28,7 – 30,2), DO (3,37- 4,88), Ammonia (P3 0,02-0,54 mg/L), CO2 (0,45 – 10,48)

    Type and Abundance of Phytoplanktons and Absorptions of Ammonia on African Catfish (Clarias Gariepenus) Cultivation, Differences of Stoking Density with Bioflok

    This research was conducted from march until April 2014 in fish Farming technologilaboratory of faculty of fisheries and marine science university of Riau. This research purposes toknow type and abundance of phytoplanktons and absorption of ammonia on arican catfish(clarian gariepenus) cultivation, differences of stoking density with bioflok technique.Experimental metods using completely random design (RAL) with one factor and faour leveltritment, each treatment done in theree times deuteronomy. Stocking density on each treatmentbegins from 20 fishes in one place for P0 40 fishes for P1 60 fishes for P2 and 80 fishes for P3by administering molasses and for each place P1-P3 as probiotics 20cc. Best result of this reserchis solid stocking 80s with total abundance 16303 indl/L, it is supported by parameter of waterquality in each treatmant where water quality consist of : temperatur 27-320C, pH 7-7.9, DO1.55-3.03 (mg/L), CO2 7.13-15.31 mg/L, phosphat 0.6173-1.2978 (mg/L), nitrate 0.5854-10.4236 (mg/l) and total organic material of water is 12.331-15.441 (mg/l)

    The Production of Siamese Catfish (Pangasius Sucthii) Intensive Cultivation in Terms of the Nature Physic Pool of Red-Yellow Podzolic, at Different Ages

    This research was conducted from April until July 2015 which is located on the village of Patin Koto Mesjid, Kampar, Riau and the Enviromental Quality Laboratory Cultivation, Faculty of Fisheries and Marine Sciences University of Riau. This research was used experimental method, by using a Completely Randomized Design (CRD) (Sudjana, 1991). Then, it is used 4 levels of the treatment (P1, P2, P3,and P4). The research procedure in this study are : 1) The choice of location which is suitable with the desired of pool age; 2) Making the sample of test; 3) measuring several parameters of the quality of soil physical. The result showed that the age of a different pool influence on some parameters of physical properties of soil and water quality parameters during the research. Besides that, during the research it is found the best treatment for pH parameters contained in P2 treatment ranges from 6.56-6.71, Parameter BV best soil treatment is at the treament P2 it is ranged 1.69-1.49g/cm3 for the treatment of texture parameters P1,P2,P4 soil fraction is Clay Loam Sandy and Clay soil fraction for P3, for the parameters soil color of the treatment P1, P2 Dull yellow orange P3, P4 Grayish yellow brown

    Abundance Moina SP. Given the Mixed Fish Meal, Soybean Meal and Bran with Different Concentration

    This research was conducted on June to July 2016 in BPBAT Jambi. The purpose of this studi to determine the abundance of Moina sp. in artificial media with different concentrations of organic matter. The method used by the experimental method completely randomized (RAL) with four treatments and three replications. Treatment with giving fish meal, soy meal and bran as media results show the highest abundance population Moina sp. and the best gift weir Giving fish meal (0.15 g) + soy meal (0.15g) + bran (0.3g) with an average abundance of 403 ind/L. Water quality during the study showed a good range for growth Moina sp. namely pH 7.01 - 8.29, Dissolved Oxygen 4.21 - 6.80 mg/L, the water temperature from 26.9 - 28.9 °C and NH3 of 0.023 - 0.21 mg/L

    The objective of the research was to determine the effect of feeding with different protein contents on the quality of water in fish culture catfish media (M. nemurus CV) in a recirculating aquaponics system. The method used in this study is the experimental method using a completely randomized design (CRD) using 1 factor, 4 levels of treatment and 3 replication, the treatment is: P0 (control), P1 (Giving pellets artificial protein content 30%), P2 (Pellets with protein content 35%) and P3 (pellet-made with a protein content of 40%. The results of this study are growth weight (g) cathfish best there is in treatment P2 (feeding with protein content of 35%) The final results of the absolute weight of 3.92 g, with the best water quality parameters, namely: 27,8-28,6oC temperature, pH 6.74 to 6.79, dissolved oxygen 5.21 to 5.26 mg / L, nitrate 4.33 mg / L, orthopospate 0.83 mg / L and ammonia 0.0055 mg / L.
