Abstract

ABSTRACTThis study aimed to determine the relationship of sea surface temperatureand chlorophyll-a by catch yellowfin fishing in the Coast of Western NorthSumatera. This study conducted in the Archipelago Fishing Port Sibolga andcontinued with image interpretation in Regional Fisheries Laboratory Faculty ofFisheries and Marine Sciences University of Riau, Pekanbaru. This research usesAqua MODIS satellite imagery level 1b data with a spatial resolution 1km. Thisstudy was conducted using a survey to get the catch and fishing Yellowfinposition data from the Fishing Port Of Sibolga Archipelago. Spatial analysismethods are used to see the distribution of sea surface temperature andchlorophyll-a. In this study sea surface temperature more dominant fish catchyellowfin than chlorophyll-a. At sea surface temperature range of 27-290C andchlorophyll-a concentration range of 1,03-1,09 mg/m3 dominant in January,yellowfin caught more fish with 221,773 tons while the dominant sea surfacetemperature 30-320C and chlorophyll-a concentrations 1,25-1.41 mg/m3 inDecember yellowfin caught fish less of 2,892 tons.Key Words : Sea Surface Temperature, Chlorophyll-A, Satelite Imagery, AquaMODIS, Thunnus albacares.

ABSTRACTmuhammadzikri191@yahoo.co.idThis research was conducted on 18th to 27th September 2014 in the waters of Rhu Bay Village, North Rupat District, Bengkalis, Riau Province. The purpose oh this research was to determine the longline catches (kg), the type and amount of catches in the morning and afternoon in the Fish Aggregating Device (FADs) in the waters of Bay Village, North Rupat Rhu, Bengkalis District, Riau Province. The method that is used in this research was a survey method, which is taking the catch area Fish Aggregating Device in the morning and evening for 10 days. The catches during the research were 14.8 kg (35 fishes). The types of longline catches of the highest and the lowest in the morning and afternoon of the fish aggregating Device as a whole is composed of fish species Polynemus tectraductylus was 6.84 Kg (17 fishes) which is the highest number of catches, Chirocentrus Dorab was 4.87 Kg (7 animals), Arius sp was 1.62 Kg (4 fishes), Diodon holocanthus was 0.72 Kg (4 fishes), and the lowest longline catches Pristigasteride was 0.75 kg (3 fishes). From the Ttest showed that the entire weight of longline catches in the morning and afternoon showed Thit value = 3.41, while Ttab = 2.22814, it is means that H0 is rejected. This is means that there are differences in longline catches the morning and afternoon Fish Aggregating Device. From the calculation of Ttest showed that there is no differences composition of longline catches in the morning and afternoon at Fish Aggregating Device.Keywords : Catches compotition, in the morning-in the afternoon, longline, fishaggregating device.

Abstract

ABSTRACTThis study will be conducted in June 2014 which was held at the Laboratory of Materials Capture Device Utilization of Water Resources of the Faculty of Fisheries and Marine Sciences, University of Riau. The method uses a completely randomized design (RAL) with the untreated control with 10 replications. Strength of PA yarn without treatment has a breaking strength of 12.1 kgf, elongation 15:35 mm, while break strength and elongation threads preserved highest of yarn treatment C with a value of 16.0 kgf breaking strength; elongation of 19.5 mm, followed by treatment B with a value of 14.5 kgf breaking strength; elongation of 17.9 mm; and treatment A with a value of 13.3 kgf breaking strength elongation of 16.6 mm. The result of a completely randomized design (ANOVA) yarn soaked with bark extract greetings with different concentrations ie 0.3 kg / liter of water 0.5 kg / liter of water and 0.7 kg / liter of water was highly significant (p <0 , 00) to the threads of control.Keywords: Concentration, End Strength , elongation

Abstract

ABSTRACTThe study was conducted in Penyengat Island in June 2014, Tanjungpinang City, Riau Islands Province. The Penyengat Island coastal is known as fishing area and as cruise line and this island has seagrasses ecosystem. The research aim was to determine the structure of bivalves and its relationship with seagrass density by using the survey method. There were 3 station choser each station were 3 placed line transects, and each transects have 3 plot with the area of 1 x 1 m². The resulsts of the study showed there were 8 species of bivalves from 5 famalies and 6 genus. The species were concisting of Meritrix meritrix, Mercenaria mercenaria, Pina bicolor, A granosa, A inflate, Barbatia bistrigata, Crassostrea gasar and Placuna placenta. There were two species of seagrasses identified, i. e. Enhalus acoroides, and Halophila ovalis. Based on simple regression analysis it was concluded that the relationship between the density of seagrass density and bivalves population had a very weak correlation (r = 0,06).Keywords: Penyengat Island, Bivalves, Seagrass, Community structure

Abstract

AbstractPeat water is naturally brownish colored and it has high turbidity and thus it is not sufficient to support the life of fish, especially Cyprinus carpio. To understand the effectiveness of the continuous system processor to reduce the color and turbidity in the peat water and to understand the ability of C. carpio to live in the treated peat water, a study has been conducted in May 2014. The peat water was obtained from the Tarai River and then was processed using “a continuous processor”. The water was pumped into water tank (120L), added with lime (225 gr), Aluminum Sulphate (225 gr), aerated and filtered with layers of zeolit, charcoal and sand. Sampling was conducted 4 times, once/week. Results shown that after being treated, the color of the water become clear (from around 890 to 7.49 PtCo) and the effectiveness was 99.17%. The turbidity decrease, from 40.0 NTU into 2.61 NTU (effectiveness 93.41%). Survival rate of Cyprinus carpio that were reared in the treated water was 100%. Based on data obtained, it can be concluded that the continuous system is effective to reduce the color and turbidity of the peat water.Keywords : Peat Water, Continuous system processor, water color, turbididty, Cyprinus carpio.

Abstract

ABSTRACTThis study was conducted in May 2014 held at the village of Batu Belubang Senayang District of Lingga District Riau Islands Province. The purpose of this study is to find the right form valves or better to be used by fishermen. This study uses three treatments, namely: valves the shape pointing up, valves whose shape pointing downward, and valves that looks straight ahead. The method used in this study is the experimental method, the entire unit of experiments carried out in the field. From this results, the catch valves leads down better than the catch valves pointing up and straight forward, both in the amount of weight (kg) and in the number of individuals (tail). Basic trap catches with all three forms of the valves dominated by domersal and carnivorous fish.Key words :
