The Production of Striped Catfish (Pangasius Hypophthalmus) in Intensive Cultivation Reviewed Water Quality Parameters of Red Yellow Podzolic in Different Age

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

Zeolite Absorption as Ammonia Filter in Waters and the Effects on Water Quality

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

The Abundance of Plankton in Fish Breeding Basin African Catfish (Clarias Gariepinus) with the Frequency of Inoculant Bactreria in Engineering Biofloc

This research was conducted 17 juny to 16 july 2015 held at environmental quality laboratory cultivationand fish farming technology in order to determine the frequency of bacterial inoculants on pisciculture tub African catfish (Pangasius gariepinus) in promoting the development of plankton abundance with biofloc techniques. The method used in this research is experiment by using completely randomized design (CRD) 1 factor, 5 level treatments and 3 replications. The peak of plankton abundance on all treatments occurred on day 6, 14, and 22. The classes are Chlorophyta, Cyanophyta, Bacillariophyta, Xantophyta, Protozoa dan Rotatoria. The best average abundance of plankton is found in the frequency of bacterial inoculants 6 times every 5 days as many as 12,640 ind/L. It is supported by parameter of water quality in each treatmant where water quality consist of: temperatur 27-32 0C, pH 6,6-7,2, DO 2,39-4,80 mg/L, C02 3,99-18,11 mg/L, amonia 0,0005-0,0322 mg/L, turbidity 0,12-31 NTU, nitrate 0,12-8,04 mg/L, phosphate 0,13-1,18 mg/L and organic materials 13,90-26,99 mg/L respectivel

Application Palm Oil Waste by Different Concentrate of Gill Morphology Damage and Survival Rate of Snake Skin Gourami (Trichogaster Trichopterus Blkr)

The research was conducted from Desember 2014 to January 2015 at Water quality Management laboratory Fisheris and Marine Science Faqulty of Riau University. The aim of the research was to investigate the effect Palm oil waste by different concentrate of damage gill and survival rate of snake skin gourami (Trichogaster trichopterus Blkr). Experimental method was applied in the research with five treatments and three replications. The treatment in the research was application palm oil waste with concentration of P0 : Without palm oil waste (control), P1: 1,286 ml/L, P2: 12,86 ml/L, P3: 25,72 ml/L and P4: 38,58 ml/L. The result showed the change of gill morphology structure of snake skin gourami (Trichogaster trichopterus Blkr). Changing on gill morphology showed the damage using palm oil waste 1,286 ml/L by survival rate 46,6 %. Changing on gill morphology structure indicate the damage is begun from hipertropy, poliferasi sel, hyperplasia, degenerasy and nekrosis. Meanwhile supreme gill morphology damage is occured on application palm oil waste 38,58 ml/L and the lowest survival rate of 26, 6%
