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.

This research was conducted on February to April 2017 The study areas Marisa Beach, Tanayao Beach, Botogawu Beach and Fofola Indah Beach. A survey method was applied and data obtained from 189 respondents were descriptively analyzed. The aimed of this study was to review the objects and issues of marine ecotourism has been conducted from February to April 2017. The study areas Marisa Beach, Tanayao Beach, Botogawu Beach and Fofola Indah Beach. A survey method was applied and data obtained from 189 respondents were descriptively analyzed. Based on research results Tuhemberua Subdistrict is potential and suitable to be developed as marine ecotourism area. Activities that can be developed are swimming, sunbathing, beach recreation, water sports and boating. The main problems identified are as follow: less participation of stakeholders in developing the marine ecotourism, less attention from local governments in providing adequate facilities in each marine ecotourism object. Scores of Tourism Suitability Index (TSI) was 97.44-100% and scores of Carrying Capacity Area was 222-318 persons/day. The highest TSI score was obtained in the Botogawu Beach and Fofola Indah Beach (100%) and the highest Carrying Capacity score was in the Fofola Indah Beach (318 persons/day). There were three main strategies for developing the marine ecotourism activities, namely anticipating and handling the threat of coastal abrasion and degradation, cooperation with travel agency as well as coastal conservation efforts.

This study aims as follows: 1) To determine the status of ecosystem-based fisheries management or Ecosystems Approach of Fisheries Management (EAFM) in the domain of fish resources for terubuk fish in Bengkalis Regency, Riau Province. The method used in this research is survey, observation and interview methods. The results of this study indicate that the indicators for the Composition of Catched Species and ETP Species of Fish Resources are still in good status. Meanwhile, indicators that need to be prioritized for improvement in sustainable fisheries management in the future because it is already in a moderate to bad status are Raw CPUE and Fish Size Trends. The conclusion of this research shows that fisheries management for terubuk fisheries (Tenualosa macrura) is still in good condition with green flag modeling and a mean value of 2,7.

This research was conducted on April to November 2015 in the and continued until September 2016. This study aims to determine the purpose of this study is to obtain a picture of population dynamics and distribution of fish Terubuk (T. macrura) based on data and information about: population density, gender ratio, size and growth, spatial distribution / spatial distribution And ruaya / Migration Fish in the waters of Bengkalis Regency. This research uses survey method, where fish terubuk serve as the object of research while Fishing Fishing Terubuk in waters of Bengkalis Province Riau Province as a place of research. That includes three districts namely Bengkalis District, Bukit Batu and Siak Kecil. Acoustic data is processed using SONAR ver.4 software. Based on research results the potential value of fish stock (pias) and terubuk female (terebas) is 26.9 tons / year, with the stock density reaches 17.2 kg / km2. The spawning areas are in the vicinity of Lalang Strait and P.Padang Strait until encountered by Bengkalis Strait in the peak phase of the bright moon and the peak of the dark moon. Survey results indicate that migration or outrageous fish ruaya not only affect spawning factors but there are other important factors namely growth and sex transfer factors, where pale fish will always be in deep strait deepwater (Terubuk Fish Sanctuary Area / Zone 1 -6). Long-term distribution of long-term fish does not indicate a shift in the capital progression, such as long frequency data, but only fish (pias), female fish (transplant), and transitional sex fish; Where the 'Pias' group is 20 cm below; Category 'Terubuk' size 20 cm and above.

Puntius schawanefeldii is one of common fish in the Koto Panjang Dam. This fish commonly present around the floating cage culture area. Small P. schawanefeldii sometimes enter the culture cages and become trapped in the cages as they grew up. Farmers used to remove the trapped fish and put them in the cage around the cage culture area. The net caged P. schawanefeldii were not given any food, but they were able to grow. To understand the feed consumed by the caged fish and compare it with the free living fish, a study on the stomach content analysis of the caged and free living fish has been conducted on September 2022. Samplings were conducted 2 times, once/2 weeks and the stomach contents was analyzed using a volumetric method. There were 139 fishes captured. The stomach 104 fishes were full or partly full, while the stomach content of other 35 fishes were less than 25% and could not be analyzed. Results shown the stomach content of the caged and free living fish were similar, there were algae and pellets (they could not be separated), fish feed pellet remains and fish tissue remains. The Preponderance Index of each food type present in the caged fish are pellets 71.24%, mixed algae and pellets 26.76% and fish tissue remains 2.00%, while those of the free living fish are pellets 16.28%, mixed algae and pellets 70.63%, and fish tissue remains 11.44%. Data obtained in this research indicate that the caged fish receive fish feed pellets that spilled out from the culture floating nets in the surrounding area.
