Abstract

Abstract Ompok hypophthalmus Bleeker is one of fish that live in the Tarai River, a polluted river in Riau. The quality of water in the river may affects the fish health status in general, including its gill structure. A study aims to understand the histological structure of the gill of fish living in the Tarai River has been conducted in April 2018. The gill were histologically processed through alcohol series, 6mm sliced and HE stained. Types of abnormality in the gill was noted and the Histopathological Alteration Index (HAI) was calculated. Results shown that abnormality present in the gill were hyperplasia, broken epithelium, hemorrhage and curling secondary lamella. The average of HAI value was 9.7 indicates that the gill of O. hypophthalmus from the Tarai River was slightly damage.Keyword: Sheatfish, Histopathological Alteration Index, gill abnormality, polluted  river

Abstract

ABSTRACT The purpose of this research was to determine the level of consumer acceptance towards Hoeven’s carp  (Leptobarbus hoevenii) fishcake with addition of sago flour in different amounts and obtained  the nutritional content ofHoeven’s carp fishcake. The methodused was a non-factorial Completely Randomized Design (CRD) with addition of sago flour in different amountsfor fish cake  processing which consisting of 4 levels: P0 (100 grams of tapioca flour), P1 (400 grams of sago flour), P2 (450 grams of sago flour), and P3 (500 grams of sago flour) with triplicates and 12 units of experimental units. The research parameters were organoleptic test (appearance, aroma, taste, and texture) and proximate analysis (moisture, protein, fat, and ash content). The result showed that  P1treatment was most favorable by consumer acceptance, with characteristics of appearance was rather greyish colour, the specific aroma of hoven’s carp and sago flour seasoning, the specific taste of seasoning and Hoven’s carp meat),  the chewy and compact texture. Meanwhile for proximate analysis that P1 treatment contained moisture, protein, fat, and ash was 53.22%, 7.87%, 4.25%, and 4.81%, respectively. Keywords: formulation, Hoven’s Carp Fish cake, Sago Flour

Abstract

ABSTRACT    This research was conducted on November 18, 2018 until December06, 2018 in Koto Mesjid Village, Subdistrict XIIIKoto Kampar, Kampar Regency, Riau Province. The purpose of this study is to identify economic activities that are growing as a result of the presence of Patin fish culture(Pangasius sutchi) and to find out the multiplier effect of the existence of Patin fish culture (Pangasius sutchi). The research method used is the Survey Method conducted directly by observing the research object. The technique of determining respondents used is based on Purposive Sampling with the number of respondents as many as 38 owners of Patin fish culture businesses, 2 Patin fish hatchery businesses, 2 processed fish business actors, 4 feed making businesses and 4 workers from each unit.The results of the study show that economic activities that have grown as a result of the existence of three Patin (Pangasius sutchi) cultivation business, namely: the business of fish stocking, feed making business, and processed fish business. l The large economic impact of Patin fish culture is the estimation of the velocity of money with the number of 835 ponds for one business production reaching IDR.50.007.000.000 and the turnover of money for one year reaching IDR.100.014.000.000. While the multiplier effect of the existence of Patin fish culture (Pangasius sutchi) has provided an economic impact seen from the direct impact, indirect impacts and further impacts. The value of the Type II Ratio Income Multiplier is 1.0. This shows that the Patin fish culture business has had an economic impact on the community.Keywords: Multiplier Effect, Cultivation Business, Patin Fish

Abstract

ABSTRACTPeriphyton is one of microorganisms that serve as primary producer in the aquatic environment. Research aims to determine the chlorophyll-ɑ concentration of periphyton attached in plastic substrate has been carried out in April-May 2018 in the Sail River. There were three sampling stations, namely S1 (in the upstream), S2 (in the middle) and S3 (in the downstream). Samplings were conducted once/week for a 3 weeks period. The periphyton samples were brushed from the plastic substrates (8 x 6) cm2. Water quality parameters measured were water current, temperature, transparency, pH, dissolved oxygen, free carbon dioxide, nitrate, and phosphate. Results shown that chlorophyll-ɑ concentration of peripyhton in the plastic substrate in the S1 was 11.29 μg/cm², in S2 was 14.52 μg/cm²and in S3 there was 26.21 μg/cm². The water quality parameters were as follows: water current 0.07-0.69 m/s, transparency 6.03-7.67 cm, temperature 29-30 0C, dissolved oxygen 4.8-5.7 mg/L, free carbon dioxide 13.6-14.6 mg/L, nitrate 0.29-0.38 mg/L, phosphate 0.34-0.54 mg/L. The chlorophyll-ɑ concentration indicate that the trophic status of the Sail River was eutrophic. The water quality is good and it may be able to support the life of aquatic organisms. Keywords: Lotic, sessile organism, trophic state, water quality

Abstract

ABSTRACT                             Artificial feed is one of the alternative diet to replace natural foodfor fish larvae.  The addition of probiotics to paste feed could  improve the digestibility of larvae. Probiotics are cultured products or live microbial feed suplements, which beneficially affect the host by improving the intestinal microbial balance. The aim of the research was to evaluate the addition of probiotic dosages to artificial feed on growth and survival rate of green catfish larvae. This research was conducted from July until September 2018 at the Fish Hatchery and Breeding Laboratory, Fisheries and Marine Faculty Riau University. The treatments in this research wereP0 (0 ml/kg feed), P1 (2 ml/kg feed), P2 (4 ml/kg feed), P3 (6ml/kg feed). The 8 days old larvae were rearing in 15 litreaquarium at stocking density 2 larvae/l for 40 days. Feeding was given 3 times/day at the rate 30% of biomass. Result showed  that the larvae fed 4 ml probiotic / kg  feed was the highest growth (1,7 g, 5,18 cm and 12,8 %/day), the best feed efficiency was 40,2% and the highest survival rate was 70%.Keywords :Green Catfish Larvae; Paste Feed; Probiotic; Growth;Survival Rate

Abstract

Abstract            The activities of petroleum drilling, ferry ports and leakages of underwater pipeline caused oil pollution in the coastal area of the Mengkapan Village. The presence of oil pollution may trigger gene mutation in specific bacteria and it may produce biosurfactants for degrading the oil. A study aims to investigate the biosurfactantproducing bacteria in the coastal of Mengkapan village was conducted from March to May 2018. There were 2 stations, in the petroleum drilling area (St1) and in the TanjungButon port (St2). Results shown that the highest bacterial density was inthe St2. Morphological and biochemical characeristics shown that there were 2 bacteria species, namely Bacillus sp and Pseudomonas sp present. Emulsification Index of the Bacillus sp was43% and that of the Pseudomonasspwas 54%, indicating that those bacteria were potencial for producing biosurfactant.  Keywords : Microorganisms, Biodegradationt, Oil, Emulsification

Abstract

AbstractThere are many types of makrophytaand fish in the swamp area in the Sawah Village, but there is no information on the association of makrophyta and fish in the swamp. To understand that association, a research has been conducted in August – September 2018. Sampling were conducted once /week for a month period. Puntius johorensis, Rasbora einthoveniiand Puntius lineatus were found around the community of Barclaya sp. Around the Hydrilla verticillatacommunity, there wereNandus nebulosus, R. einthovenii,Trichogaster trichopterus and Puntius johorensis. Around the Pistia stratiotes  community, there were T. trichopterus and  R. Einthovenii. While T. Trichopteruswas found around the Paspalum sp community. Even though the plants were different but the type of fish present was similar. Based on data obtained, it can be concluded that there wereno specific association between makrophyta and fish species in the swamp area in the Sawah Village. Keywords :  Makrophyta, Fish association, Blackwater swamp, Aquatic plant.
