Abstract

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.

Abstract

Climbing perch (Anabas testudineus) is the one of freshwater fishes living inRiau. Information on the biological aspect of this fish, however, is limited. Astudy aims to understand the reproductive biological aspect of this fish has beenconducted from January-March 2014. The fish was sampled once/ month for athree months period. They were 153 fishes, 68 males and 85 females, 49-145mm SL and 4-126 gram BW. Sex ratio of females and males was 1:1,25. In eachsampling, male and female fishes in 1st , 2nd , 3rd and 4th maturity stages werecaptured, and only female in 5th maturity level was captured. The gonado somaticindex (GSI) is around 0.0088%-5.8567%. Fecundity is around 4.116-13.998eggs/fish, with mature egg diameter ranged from 0.62-0.69 mm. Microscopicstudy of the ovarian structure showing that the ovary of mature femalesdominated by mature eggs and there were few amount of non vitellogenic andearly vitellogenic eggs. The atretic eggs were found in the ovary of the 5thmaturity level fish only. This structure indicates that the fish may be a totalspawner. The testes of males showing mature sperms throughout the study period,indicates this fish may be able to spawn throughout the year.Keywords: Anabas testudineus, Reproduction, sex ratio, GSI, fecundity, sexreversal

Abstract

This research was conducted in August and November 2013 in the province of Riau Strait Bengkalis. The method used in this study is a survey method . The purpose of this study was to determine the potential catches Terubuk ( Tenualosa macrura ) in Bengkalis waters. The results showed that the results of the survey of the Terubuk fish were caught fishing waters Bengkalis the month from August to November 2013. Retrieved Terubuk number and size of fish caught as many as 3554 head comprising 1082 males and 2472 Terubuk tail tail Terubuk females . Terubuk fish growth speed at the time a young age faster than when the fish is old. The rapid growth of the young - old fish occurs because the energy obtained from food are mostly used for growth. In older fish the energy obtained from food is no longer used for growth, but only used to maintain it self and replace the damaged cells.The rate of death arrest ( F ) during the study period is higher than the rate of natural mortality ( M ) , so that the total mortality rate ( Z ) during the periods of the study are determined by the rate of death arrest ( F ). Terubuk fish mortality rate during the study period due to factors at the time of capture by fishing for migratory fish spawning . Terubuk endangered fish caused by two main factors : first, the seizure at the time of entry into migratory fish Strait Bengkalis, secondly, the quality of the water into a fish alive Terubuk diminishing.Keywords : Potential , Terubuk Fish , Aquatic Bengkalis

Abstract

This study was conducted from Juni to November 2013 in The Barumun River and in the laboratory of the Fishery Biology, Fisheries and Marine Sciences Faculty, Riau University. It aims to determine the reproductive biology of the tenualosa ilisha. Sex ratio, gonad maturating level, gonado somatic index, eggs diameter, fecundity were observed visually and analyzed based on Cassei (in Effendie, 1979). While histological characteristics of the gonad was studied based on Effendie (1979).111 fishes were caught and results indicated that male and female ratio was 3,2 : 1 and it was not significantly different (X2 test). The age of maturity of males was achieved by 120 g (BW) and 160 mm (SL), while that of the female was 400 g (BW) and 270 mm (SL). The body weight may increase as the gonad maturation level increase. The range of gonado somatic index was 0,3–25,0 %. The range of eggs diameter in the 4th maturity stage was 0,2–0,9 mm in diameter. The fecundity of (number of eggs) fish with 285–495 mm (SL) and gonad weight was around 81.450–245.267 eggs. Results of histological study shown that the eggs and sperm in the gonad are on several maturity stages.Keyword : Tenualosa ilisha, Barumun river, Sex ratio, Gonadal Maturating Index, Fecundity
