This research was done in December 2013 in the waters of Sumber Jaya village Kampung Melayu subdistrict Bengkulu Bengkulu province. The method used was a survey method. Data taken consisted of 1) the location of the operation of gill net fishing gear, 2) the location of the catch in gill net fishing gear pengoperaisan, 3) water temperature, 4) salinity, 5) flow velocity, 6) brightness and 7) depth. The highest fish production in the 10 operating locations gill net fishing gear different, for gill net boats GT ≤ 5 highest and lowest 110 kg 45 kg. While gill net vessel GT ≥ 5 highest and lowest reaches 750 kg 350 kg. Physical parameters obtained for salinity in the range of 24-26 ‰, flow velocity in the range of 0.200 to 0.250 m / sec, the depth was 58-62 m range, water transparency in the range of 6.0-8.0 m, water temperature in the range of 27 -30 0C. Multiple linear regression analysis showed Total catches (Dependent Variable) with physical parameters (Predictors) obtained the effect of x on y by 54.0%, while the remaining 46% are caused by other factors. The need for further research by grouping objects larger research and predictive variables that have continuous time series in order to obtain a clearer influence between variables and objects.Keywords: water village Sumber Jaya, gill net, physical parameters, multiple linear regression

ABSTRACTThis research was conducted on September-October 2014 at the waters of the Rupat Utara Bengkalis district Riau Province, using survey method. Data taken consisted of waters environment parameters area of the physical and chemical include the water temperature, salinity, current speed, brightness, depth, and the degree of acidity (PH). Measurements were performed for ten days along with decision gill net. During the 10 days of observation obtained catches up to 94.5 kg, catches the highest number of 16 kg and the lowest catch is 7 kg, with the physical and chemical conditions. 270-300 C temperature, salinity 25-29 ‰, current speed from 0.10 to 0.33 m / sec, the brightness of 0.57 m - 1.22 m, depth of 18-30 m, and the degree of acidity (pH) 6- 8. Multiple linear regression analysis showed a very strong correlation between the catch with the environmental parameters with regression coefficient 0.948 and turns physical and chemical parameters waters have contributed to the variation 89.9% on the results of fishing.Keywords: waters Rupat Utara, gill net, environment parameters, multiple linear regression

This study was conducted in December 2014 which was held at the Laboratory of Materials Capture Device and experimental ponds Faculty of Fisheries and Marine Sciences, University of Riau. This study aims to determine the variation in diameter gravel caught as well as to determine the degree of selectivity of the catch using dredge net with mouth and slit (separator) different. The method used in this study is an experimental method of fishing is catching shellfish test, using four types of scrapers with the same two mouths, two different gap. The results of this study indicate that a more selective dredge net is the type of fingers (scratch) with a gap width of 2.5 cm and rake-type lip mussels (plate) with a slit width of 2.5 cm compared with clam rake type of fingers and lip-type (plate) with a slit width of 3.5 cm, because the type of clam rake fingers with a slit width of 2.5 cm and a clam rake lip type (plate) with a slit width of 2.5 cm has the smallest range value and the value of the variance smallest.Keywords : Dredge net, selectivity, separator, plate

Skipjack tuna (Katsuwonus pelamis) and others tuna (Thunnus), in western Sumatra is one of fisheries resources that has important economic value. Skipjack and others tuna heversted by trolling line. This study used experimental method with design of 3x3 factorial pattern. The catch During the study consisting of 2 trips with 10 days catching time, with the operation time of fishing gear for 1998 minutes, got the catch as many as 575 fish, with the average catch of fish is 0.29 tail / minute. Based on the result of data analysis, there is no interaction between the bait and the color bait to the catch trolling line in Tanjung Mutiara district Agam Regency West Sumatera Province.Keywords: Trolling line, Catch, Bait, Tanjung Mutiara district

Survey and measurement of aquatic environmental condition of SelatAsamwater was conducted in order to know the physical, chemical and biologicalparameter of SelatAsam water. Measurement was conducted at ten stations a longthe SelatAsam, and the data was collected has been analysis by using descriptiveanalysis. Nitrate and phosphate was analyzed in the laboratory of Ecology in theFisheries and Marine Science Faculty University of Riau.The result of this observation for a environment parameter were as followingtemperatures 30,10C - 31,80C, current speed 0,34 m/s - 0,77 m/s, brightness 0,40 m -1,65 m, depth 2,0 m - 23,5 m, salinity 21‰- 31‰, dissolved oxygen 7,29 mg/l -10,83 mg/l, pH 7 – 8, nitratconsentration 0,02 ppm - 0,24 ppm andphosphatconsentration 0,02 ppm - 0,51 ppm.Type of fish cought by these fishinggears were (Acetessp), (Metapenaeussp), (Parapaenopsissp), (Alphasessp),(Trissasp), (Steloporussp), (Setipinnasp), (Harpodonsp), (Trichiurus sp), (Loligo sp),(Cybium sp), (Maraenesox sp) and (Polynemus sp).According to the result analysis, can be concluded that the aquatic environmentin the coastal area of SelatAsam was still suffientas habitat for living organisms andmay be used for fishing activities

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.

Remote sensing method was used to analyze the state of the aquatic environment which aims to see the characteristics of the spatial and temporal distribution of concentrations of net primary productivity (NPP) in the western Indian Ocean Sumatra with spatial and temporal analysis. Image data NPP obtained fromsatellite image processing Aqua MODIS Level 4 in 2013. This study uses QGIS 2.18. Net primary productivity (NPP) representatives phytoplankton biomass as the basis for the food chain of aquatic organisms in the ocean. The results of this study showed that the concentration of NPP in the western Indian Ocean Sumatra in 2013 are statistically the highest in February is 739,4 gCm2/day, while the lowest in January is 554,0 gCm2/day. Spatially the concentration of NPP highest tends to be found in the coastal waters because it is influenced by the nutrients, ocean mass, chlorophyll-a and the concentration of NPP the lowest visualization tends to be at off the coast. Need to do further research on concentration NPP insitu.Keywords: Aqua MODIS Level 4, net primary productivity (NPP), the western Indian Ocean Sumatra, spatial and temporal.
