Abstract

This research was conducted on March 31 until 4 April 2014, which took place in the waters of thePambang’s Gulf Bantan District Bengkalis regency Riau province. The metode used in this study isexperimental and survey methods with case studies, namely by direct observation to look the variouslongline fishing activities.The pupose of this studi is to analyze of the catch rate with effectiveness of different sizes oflongline hooks, showing fish catches by different hook sizes, analyze the feasibility of longline effort. Theresults of this research can be an information for researchers, especially for the waters of Pambang’s Gulfon longline gear and longline feasibility effort.The results of this research show that hook rate measuring value of the hooks 7a: 11.1, 5a: 8.9, 7b:10.7, and 5b: 7.6. Based on statistic test One Way ANOVA (Analisysisi of Variance) obtained sig. 0.805 isgreater than the value of α = 0.05 level (p-value> α), its means that there is no difference in fish hook rateby hook. The results of the feasibility calculations for some criteria indicate that longline fishing effortworth forwarded, it can be seen from the value of BCR (Benefit Cost Ratio) of 1.013, FRR value(FinancialRate of Return) by 2.823%, PPC Value (Payback PeriodofCapital) of 35.422 years.Keywords : mini longline, analyze, effort feasibility, Pambang’s gulf

Abstract

A study on the diversity of phytoplankton in the Kandis River was conducted from January 2014. This research aims to understand the type and abundance of phytoplankton in the Kandis River . There were three stations with 3 sampling points in each station. Samples were taken 3 times, once a week and they were analyzed in the marine productivity Riau University.Result shown that the phytoplankton obtained were consist of 15 species, they were belonged to of 3 classes, namely Chlorophyceae (5 species), Bacillariophyceae (3 species), and Cyanophyceae (7 species). The average of fitoplankton abundance was around 1237-1480 cells/l. General water quality parameters are as follow: temperature: 290C, brightness: 30-32,5 cm, current speed: 0,08-0,12 m/s, pH: 5, DO: 35–3,7 mg/l, CO2: 11,88–12,9 mg/l, nitrate: 0,01–0,2 mg/l and phosphate 0,02–0,23 mg/l. Based on phytoplankton abundance, the Kandis River can be categorized as oligotriphic river.Keywords: Diversity. Phytoplankton, Kandis River

Abstract

The research was carried out on July until August 2013 in the Fish Nutrition Laboratory, Faculty of fisheries and Marine Science University of Riau, Pekanbaru. The purpose of this study was to remove HCN from rubber seed and See influence treatment of nutrients. so the rubber seeds can serve as fish feed constituents. This study used a Randomized Complete Design (RAL) with nine treatment three times in rreplication. R0 = Without treatment, R1 = Boiling rubber seeds open for 30 minutes, R2 = steaming open rubber seeds for 30 minutes, R3 = rubber seeds drying out under sunlight for 12 hours, R4 = rubber seed soaking in running water for 36 hours, R5 = combination of steaming open rubber seeds for 30 minutes and drying out for 12 hours, R6 = combination of soaking for 36 hours with steaming open for 30 minutes, R7 = combination of soaking rubber seed soaking in running water for 36 hours with an open boiling for 30 minutes, R8 = combination of Boiling rubber seeds open for 30 minutes and drying out for 12 hours with sun light. The result showed that combination of Boiling rubber seeds open for 30 minutes and drying out for 12 hours with sun light (R8) was the most effective way to decrease HCN content, and gave better quality of rubber seed meal for ruminant feed.Key words: Detoxification, HCN, Rubber Seed.Nutrients.

Abstract

This research was conducted in March 2014 in the coastal waters of the Village of Kuala Enok of Indragiri Hilir Regency in Riau Province. The purpose of this study was to determine the level of bacterial contamination of E. coli as an indicator of pollution on “tembakul” (P. schlosseri) fish in the coastal waters of Kuala Enok. Tembakul fish sampling conducted at three observation station, station I is located in the territorial waters adjacent to residential, station II is located in the creek waters, and station III is located in the open sea waters. Samples of “tembakul” fish were analyzed by using the MPN method three series tube at the Laboratory of Microbiology and Biotechnology of Fisheries and Marine Sciences Faculty of University of Riau. The yield on the analysis of the sample gills, digestive tract and fish meat tembakul showed that at the settlement waters and the creek waters the number of bacteria was 1,100 MPN/g but had differences on the meat at the open waters with an average of 747.67 MPN/g. The results showed that the innoculation of bacteria growing at the time of isolation was from the coliform group. Total coliform values ​​at each point of observation station was above the food quality and safety standards required by BSNI 7388: 2009 and BPOM (Agency for Food and Drug Administration) of the maximum contaminant limits in food is 10 MPN/g in fresh meat.

Abstract

This research has been done from March to April 2014 in the Bakuok Lake,Aursati Village, Tambang Subdistrict, Kampar District, Riau Province. This research aimsto understand the vertical profil of nitrate in this lake. The research used survey method.The nitrate samples were collected from three station namely station I at inlet of lake,station II in the middle of lake and station III in the end of lake. There were three samplingsites in each station were in the surface, 1,5 Secchi depth and bottom. Sampling was donethree times, once a week. The result shown nitrate concentration in surface : 0,01-0,03mg/L, in 1,5 Secchi depth 0,03-0,06 mg/L and in the bottom 0,05-0,12 mg/L. The nitrateconcentration in surface lower than in the 1,5 Secchi depth and in the bottom and nitrateconcentration increase with the depth. Water quality result shown pH:6, DO: 1,78-5,33mg/L, CO2: 4,66-15,31 mg/L, depth: 208-332 cm, transparency: 74,3-93,7 cm andtemperature: 29,6-30oC.
