Abstract

Develop fishing with regard to the code of conduct for responsible fisheries (CCRF) as suggested by the FAO. The objectives of the research were: 1) analysisstatus of fish resources utilization in Dumai, and 2) analysis fishing technology thatis good to be developed in Dumai (biology,social and techno-economic). Thisreseach was focused on fishing gears i.e. Bottom long line, Scoopnet, Portable trap.Result of research indicated that exploiting of fish resourcees demersal in territorialwater Dumai over Total Allowable Catches (TAC) 80% from MSY. Sondong isfishing gear of main priority of development with regard to CCRFKeywords: Development, by Demersal Resources, TAC

Abstract

This research was conducted from 14 – 28, May 2009 at Kelurahan Pandan Central Tapanuli of North Sumatra Province. The method used in this research is surveymethod. research results indicate that the characteristics of waves in coastal watersthere is Pandan wave breaking before reaching the coastline and affected by theshallow depth and tide, the flow velocity at the time of pairs ranged from 0,04 to0,23 m / s and at low tide ranged from 0,11 – 0,48 m / s. Type of tide in coastalwaters is a type of mixed biased doubles daily. In a day happens twice for both tideand ebb with the different of time and height. Pandan beach slope is gently slopingbeach that ranges from 0.9 - 1.9%.Keywords : Characteristic, wave, current and tide

Abstract

This research was conducted in May 2009, in the waters of Muara Aek Tolang Pandan Central Tapanuli of North Sumatra Province. The purpose of this study wasto map the distribution pattern of nitrate and nitrite content and O2 content (DO)dissolved in the mouth of the river Aek tolang horizontally. The method used in thisresearch was survey method. The primary data obtained from direct measurementsand sampling directly in the field and then tabulated and analyzed in the laboratoryare discussed further in descriptive, while secondary data related to research obtainedfrom the relevant authorities. spreading pattern of Nitrate and Nitrite concentrationdistribution was influenced by tides and currents. It can be seen by the differences inconcentration at the surface and ground waters at high tide and low tide at the samestation point. At the time of ups and downs have a much different variations on eachstation. The concentration of dissolved O2 measurements conducted at research sitesat high tide waters ranged from 111.6 ppt - 442.3 ppt. Based on measurements takenin Coastal Estuary Aek Tolang Pandan then the quality of waters in the study area nogood.Keywords: Nitrate and nitrite content, O2 content (DO)dissolved, Spreading

Abstract

This research was conducted on August 2008 with purpose has to know the characteristics of sediment at estuary of Indragiri river. The method used in thisresearch was survey method.The research found that there were 2 fractions of sediment I.E. mud and sand withthe type of sediment that were mud, sand, and muddy sand. Mean score for thesediment at the estuary of Indragiri River were between 1.72 to 7.14 Φ anddominated by medium class of silt and coarse silt. The sorting score were between0.58 to 2.10 Φ and dominated by a poorly sorted classification. Skewnes valueindicates the estuary area described that the coarse sediments particles and areas farfrom the mouth of the river showed a trend of fine sediment particles.Keyword: sediment, mud and sand

Abstract

The objective of this study is to investigate the role of fishery sector ineconomic regional of Riau Province. Data showed that the contribution of fisherysector to PDRB of Riau province is relatively small, namely 3,80 % in 2003 and thandecreasing until 3,70 % in 2007. At the same period fishery sector contribution 3,24% and than decreasing until 1,78 % for available employment in Riau Province.Fishery sector included economic base of Riau Province, during period 2003-2004fishery sector is base sector for available employment, but period 2005-2007 nonbase sector. Fishery sector have the income multiplier effect is relatively high, but thedecreasing from 32,32 in 2003 until 28,66 in 2007. Multiplier effect for availableemployment is 80,10 in 2003 – 2004. Regarding the potention of fishery is relativelybig, whereas the level of its exploitation have not been optimal, so fishery sector isimportant to be a priority in regional economic development in Riau Province.

Abstract

This study was carried out in March to April 2010 at Dumai fishing base. It aimed to learnthe correlation of fishingtrip frequencies of gillnetter on the amount of logistic needed indifferent monsoon seasons (i.e. north and west monsoon seasons). Field survey methods wereapplied and regression analysis was used for further analysis.The result showed that there were strong correlation between the fishingtrip frequenciesand the logistics needed for both seasons. Moreover, the correlation index of the fishing trips andthe logistics, in term of fuels and ice, was lower in the west monsoon season than the eastmonsoon season. In contrast, the correlation index was bigger in term of the freshwater for thetrips for both monsoon seasons. The linier regression lines for each analysis were Y = 153.34 X –23.044 for Fuels; Y = 255.9 X + 37.785 for Ice; Y = 168.05 X + 6.5913 for freshwater during thewest monsoon, while Y = 159.95 X – 29.826 for fuels; Y = 314.59 X + 61.927 for Ice; and Y=154.47 X – 14381 for freshwater during the east monsoon.Key word: fishing trip frequency, fishing logistic
