Abstract

The survey was conducted in July 2015, in the village Bukitbatu, Api-api andTenggayun, Bukitbatu district in Riau Province.The purpose of this study was to find thebest location suitable for fish landing building. The method used is the method review /revise the field. Can be seen from the survey data in the technical aspects, fisheries, socioeconomicand infrastructural purpose of the examination of the three villages.The location in the village Tenggayun have advantages, including the opportunity forfishing based on factors such as the number of fishing gear, fishing, the fishing fleet and thenumber of population, which is more than Bukitbatu villages and Api-api. Waters in thevillage Tenggayun fishery potential confounding factors and population factors get thehighest score compared to two other villages, with 55 points and 30 points. The final score ofthe third evaluation village consists of 187 points for Bukitbatu village, 173 points for thevillage burning and 195 points for Tenggayun village. The results of the research using thescoring method showed that the location in the village Tenggayun is the best place to build afish landing sitesKeywords: Selection of location, Fish Landing Place

Abstract

The research about Fishing Ground Gill Net Surface in the waters of theBogak Besar Noni Teluk Serdang Bedagai North Sumatra Province held on 23August 2014. The aimed of this to determine the state of the marine environmentoperation of gill nets surface such as depth, brightness, flow velocity, temperature,salinity, pH, and the type of fish caught in the waters of the Great Bogak. Themethod used in this study is a survey method that is by measuring the directobservation of environmental parameters and operation of a surface gill netfishing gear research location. The data collected in this study are: demography,topography, depth, brightness, temperature, salinity, current velocity, and pH. Thecatch and the measurement of these parameters are collected and then tabulatedinto a table and analyzed descriptively.The observation of environmental parameters during the study was thetemperature ranges from 28 0C - 30 0C, Flow ranges from 0.15 m / s - 0.25 m / s,the brightness ranging from 0.80 m - 1.13 m, Kedalama ranged between 10 m - 16m, salinity ranged between 23.4‰- 26.2‰and pH (acidity) ranged from 7-9.Keywords: Gill net, gill net operating area

Abstract

This purpose of this study to look at the spatial and temporal variations in the concentration of chlorophyll-a with aqua MODIS satellite image and look the relationship between the concentration of chlorophyll-a and catch of tuna (Thunnus sp) in West Sumatra by using correlation analysis. The location of fishing ground tuna (Thunnus sp) in West Sumatra at 00 0’ 0’’ S - 50 05’ 0’’ S dan 900 3’ 00’’E - 1020 37’ 00’’ E. The based coordinate of fishing ground and analyzed distribution of chlorophyll-a used satellite imagery of aqua MODIS in 2013, the catched of tuna held in distribution chlorophyll-a ranging 0,152 mg/m3 – 0,255 mg/m3. The catch is highest January (West season), April (Season West-East), July (East season) and October (Season East-West). The high catches of the highest of the season because effort high. Based on the value CPUE, in August categorized as good month with the arrest of most value CPUE 16.4142 kg /setting with catches of 22 670 kg (10%) of the total catch of 235 217 kg. The analysis showed height correlation between concentration of chlorophyll-a and tuna catches with coefficient correlation (r) and coefficient determination (R2) respectively 0,97 and 96,33%.Keyword : chlorophyll-a, Cacthed Tuna (Thunnus sp), aqua MODIS, correlation of coefficient (r) and coefficient of determination (R2).

Abstract

The purpose of this study is to determine the area tishi tor long line with a heat map setting in western Sumatra in 2015. The method used in this study is a survey method. The results of this study indicate the location of long line fishing ground is in the zone of archipelagic waters, depths, territorial sea, contiguous zone, ZEE and the high seas. seen from the results of catching the most is the transitional season II in the amount of 47. 232 kg while the catch at least the first transitional season that is equal to 17. 783 kg. significant correlation level with the coordinates of the catch and the more extensive range area of the arrest, the greater the results obtained fishermen. Poot arrest hos point fewest arrests West season with one point while most is the transition season 2 is two points hotspots with a radius of 0.2.Keywords: heatmap setting, Long Line, hotspots, point coordinates, fishing ground

Abstract

Has conducted a study to determine the pattern of fishing season bilis (Stolephorus Spp.) in the waters of the Strait Asam Meranti Islands regency of Riau Province with method survey /direct observation, with use some formulas including average, variance, standard deviation, maximum value, minimum value and range. Based on the analysis, patterns bilis season in waters of the strait starts from the beginning of December to March and July to September and entered the peak months in January and August, the first transitional season in April-June and October-November switchover II. the catch is affected by the monsoon, season affected the West Wind and East Wind ongoing season, when the North and South Season (transitional season) bilis difficult to obtain due to the influence of big waves and temperature begin to warm water.Key words: pattern wind season, the average catch, the fishing season bilis

Abstract

Sea Surface Temperature (SST) and chlorophyll-a factor were often used in determining fishing ground area. This research aimed to know variability spatial and temporal SST and chlorophyll-a at west sumatera aquatic. This research use the data of SST and chlorophyll recorded by satelite of aqua modis with spatial resolution 4 km and temporal resolution monthly data. The high mean value of SST was found on first switchover season with value 30,330C and the low mean value of SST was found on west season and second switchover season with value 29,630C. The high mean value of chlorophyll-a was found on second switchover season with value 0,16 mg/m3 and the low mean value of chlorophyll-a was found on east season with value 0,13 mg/m3.Keyword : Variablity, SST, Chlorophyll-a, Spatial, Temporal, Aqua MODIS, West Sumatera
