ABSTRAKThis research wes conducted on agustus , 2014 in Desa Bantan TengahKecamatan Bantan Kabupaten Bengkalis. This study aimed to anderstand thephysical and chemical parameters on longline fishing ground. There were 3sampling points, water quality parameter were measured everyday for 10 daysperiod. analytical description was used to evaluate the relationship betweenlongline catches and the environmental factors such as dissolved temperatur,salinity, current speed, depth of water, brigthness and pH, on this research bydescriptive analysis.Everage weigth of catch is 1.3 kg, consist of Silver Conger (muarenesoxcinareus), kuro (Eleutheronema sp), Red Snapper (Lutjanus sp), Deep Leatherskin(Scomberoides tala), Barracuda (Sphyraena sp), Gerot-Gerot (Pamadaysmaculates).

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

Abstract

The purpose of this study was to determine the variability of Catch Per Unit Effort (CPUE) and chlorophyll-a and see the connection between the catch squid and chlorophyll-a concentrations found in the waters north of the island of Java in 2016. The data used is satellite image data Aqua MODIS Level 3 and using Quantum GIS applications 2.18. The analysis uses spatial analysis to see the variability of chlorophyll-a and CPUE while the analysis of the relationship between CPUE and chlorophyll-a simple linear regression. The results of the spatial analysis of data Aqua MODIS Level 3 has the highest maximum value is 63.443 mg / m³ in May with a minimum value is 0.070 mg / m³ and the average value is 1.160 mg / m³. From the results of linear regression analysis has a value of r is 0,4483 so that the effect of the concentration of chlorophyll-a to fluctuations in CPUE amounted to 20,1%.Keywords: Spatial Analysis, Aqua MODIS, Chlorophyll-a, and correlation of coefficient (r).

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
