Tidal analyzedhave been conducted at PulauJemur waters. Fortnightlytidal range was measured by peil-schall. Harmonic Admiralty analyzed wasapplied to find out the Formzahlnumber.Average tidal range was 2,7 meters, meanlow water level (MLWL) 0,44 meters and mean high water level (MHWL) was4,97 meter. The hihgest tidal waters was 5,3 meters and the lowest was 0,0 meter.Based on Formzahlnumber F = 0,17 the type of tidal is semidiurnal. Flood andebb tide occur twice a day where one tidal range is similar in height from theother.

Fish terubuk (Tenualosa macrura) isone of thefive species terubukspecies in the world. This fish is a fish Bengkalis community pride,but thepopulation has fallensignificantly comparedto previousyears. Thisstudy aimed to examine the various aspects in view of abundance and exploitationrates of fish terubuk at this time.From the research results obtained in the waters of fish terubukBengkalis contained in two age groups of "pale" and "terubuk" with the rangeof 15-20 cm length and pias for the range of 21-43 cm length for terubuk.Looking at the various parameter of the population, on fish stocksterubuk currentlyexperiencing overfishing. Thisisevidentfrom thevaluesof population parameters suchas growthrate (K)of 0.62 andamaximum standard length (L ∞) = 46.62 cm; arrest mortality rate(F) of 1.853 isgreater than the rate of natural mortality (M ) of 1.22.Alleged amount of fishstocks terubuk today in the form of biomassper recruit an average of (B / R)of 0.80 kg per recruit in the catch perrecruit (Y / R) of 0.45. With the levelof exploitation that has exceededthe maximum sustainable (MSY), which isreflected in the value of Exploitation Rate (E) in excess of 0.5 is 0.603.

The experiment has been conducted from February to April 2011 in FishNutrition Laboratory and the experiment fish pond of the Fisheries and MarineSciences Fakulty of Riau University. The aim of this experiment were to know theeffect of linoleat fatty acid and linolenic fatty acid on growth and food efficiencyof catfish fingerlings, Ompok hypopthalmus. The experiment used completlyrandomized design, five treatments and three replications. The treatments werelevel of linoleat fatty acid and linolenic fatty acid in catfish diets: A (2%:0%), B(1,5%:0,5%), C (1%:1%), D (0,5%:1,5%) and E (0%:2%) respectively. Thefingerlings were kept in floating cages (1 x 1 x 1.2 m) for 56 days with density of20 fingerlings per cage. The result indicate that level of linoleat fatty acid andlinolenic fatty acid in catfish diets has influenced daily growth, feed efficiency,protein retention and fat retention of fish. The best result was the D (0,5%:1,5%)that the daily growth rate was 2,2%, feed efficiency 28,10%, protein retention17,81% and fat retention 194,2%. Water quality for this experiment weretemperature: 26-30oC, pH 5-6, DO 5,1-6,5 ppm and ammonia 0,006-0,57 ppm.

Coral reef ecosystems is one of the major coastal and marine ecosystems that haveecological value, economic and aesthetic. Unfortunately, the ecosystem continuesto come under pressure from a variety of activities such as fishing, tourism,pollution and other activities. This study aims to determine the condition of coralreef ecosystems in the Regional Marine Protected Area (RMPA) East Bintan.Observations of coral reefs is done using a modification of the square transectmethod and condition of coral reefs can be estimated by the percentage of livecoral cover approach. While the analysis of water quality refers to the APHA. Tosee the linkages between the biophysical environment-chemical characteristics ofwater with each of the locations used multivariable statistical analysis approach toPCA (Principal Component Analysis). The results show that coral reefs in theMarine Protected Area Region East Bintan including the condition of 'being' to'good'. This condition is caused by the pressure of population activities in the pastsuch as sea sand mining, leaching of bauxite tailings disposal, tailings sandmining land, and the impact of destructive fishing continues until the timeresearch was conducted. Meanwhile, the measured water quality is below the seawater quality standard for marine life. Further analysis of the factors in marineenvironment conditions with live coral cover showed that the live coral cover wasnegatively correlated with most variable environmental parameters such as flowvelocity, salinity, TSS, DO, BOD5, nitrate, sediment and algae. except fortemperature, brightness, and depth and phosphate positively correlated.

Characteristic of population biology of the “sepetang” clam has been studied inDumai mangrove ecosystem from November 2010 to October 2011. This researchwas to study the patterns of the population growth, mortality and recruitment ofthe clam P. acutidens. Sampling was monthlyfrom plot 1 m x 1 m quadratictransects. The result showed that growth pattern of P. acutidens was negativeallometric with asymptotic length (L∞) 92.71 mm.The annual growth coefficient(K) and total mortalitywere 0.59 and 1.87 per year, respectively. The naturalmortality was probably related to environmental condition. The recruitmentoccurred every month, the peaks occurred on April (15.93%) and August(13.16%).

Main problems facing by fish farmers in utilizing of swampy soil as otheralternatives for fish culture area are water and soil quality such as low soil andwater pH, uncertainty water supply, land topography and lack of nutrient content.In order to increase nutrient content in swampy soil, it should give manure. FlyAsh consist of P : 10.0-12.3 g/kg, K : 16.0-65.8 g/kg, Ca : 26.6-32.1 g/kg, Mg : 24.4-30.8 g/kg, Cu : 0.16-1.26 g/kg, dan B : 0.20-0.27 g/kg. Fly Ash an alternative thatcould be used in nutrient recycling or to return nutrient content on land.Application of fly ash could improve swampy soil and adding nutrient content forplant. The aim of this research was to investigate the effect of palm fly ashaddition on phytoplankton growth. Complete Random Design with one factor,four treatments and three replications was applied. Results showed that there waspositive relationship between concentration of fly ash and phytoplanktonabundance. Fly ash concentrations applied were: P0 (without fly ash), P1 (246.1g/m2), P2 (492.2 g/m2) and P3 (738.3 g/m2). Results shown that the bestphytoplankton abundance was obtained from P3 (738.3 g/m2) with phytoplanktonabundance was 2,945 cell/ml, while the worst was P0 (without fly ash) withphytoplankton abundance 1442 cel/ml. 17 species of phytoplankton were inventedin the research consist of 5 species of Chlorophyceae, 4species ofCyanophyceae, and 8 species of Bacillariophyceae respectively. The organicmaterial of soil content from 60.40-89.75 %, nitrate concentration 0.129-0.841ppm, temperature 26-35oC, water pH 5-9, turbidity 1-17 NTU, DO 2.1-4.5 ppm,CO2 11.99-46.57 ppm, orthoposphate concentration 0.079-0.524 ppm, hardness17.00-29.67 ppm.
