This river is relatively polluted as there are human activities present in the riverside along the river and the pollutant produced flown to the river. Due to pullutant accumulation, water quality in the downstream of the river may be worse than that of the upstream. As water quality affects the health status of fish, the health condition of fish living in the upstream and downstream of the river might be different and it may be reflected in the histological structure of main organs of the fish. To understand the difference of histological structure of the gill, kidney and liver of O. hypopthalmus, a study has been conducted. Fish samples were captured from the upstream and downstream of the river. Gill, kidney and liver tissue was processed for histological study (formalin fixed, alcohol series processed and HE stained). Results indicate that the histological structure of the fish from both sampling areas showing abnormality symptoms. In the gill tissue of fish from both areas, most of secondary lamella are fused and abnormality symptoms such as hyperplasia, hypertrophy and necrosis are present. In the kidney and liver tissues, there are hemorrhage, mineralization and cell degeneration. The kidney and liver of fish from the downstream shown more mineralization spots than that of the upstream. These data suggested that the fish living in the upstream and downstream of the Siak River have been exposed to relatively polluted water that negatively affects their health in generalItem The Improvement of Ovulation Stimulation and Egg Quality of Pawas Fish (Osteochillus hasselti CV) for Artificial Spawning Requirements in Seed Production(2017-10-14) Sukendi, Sukendi; Thamrin, Thamrin; Putra, Ridwan MandaThis study aims to determine the increase of ovulation stimulation and egg quality of Pawas (Oseochilushasselti CV) with ovaprim’sstimulifor artificial spawning requirements in baby fish production.

Mangrove ecosystem is a buffer and has a multifunctional. Physically, mangroves have an important role in protecting the coast from waves, winds, storms, keeping the coastline stable, preventing abrasion and intrusion, accelerating land expansion and protecting river banks and beaches. Ecologically, the mangrove ecosystem acts as a life support system for a variety of aquatic organisms and terrestrial organisms including the place of fish seeds, shrimp and shellfish, habitat for various birds, and other biota, as a nursery ground, feeding ground, and selter area. Socially and economically, mangrove ecosystems are the source of livelihoods of coastal communities including ponds, wood and non-timber forest products. In addition, mangrove ecosystems contribute to controlling global climate through carbon sequestration. This study uses qualitative methods by conducting in-depth interviews or in-depth interviews. The results found that the mangrove ecosystem in Bengkalis Regency has a value of direct use, value of indirect use, value of choice, value of existence and value of potential mangrove resources to be cultivatedItem Reproductive Biology Of Belontia Hasselti From The Tambang Village, Kampar Regency, Riau(2016-04-04) Putra, Ridwan Manda; Windarti; Simanjuntak, Esa FBelontia hasselti is belonged to Belontiade family and commonly inhabit flood area and irrigation canals in palm tree plantation areas in Riau. This fish is commonly consumed by local people or reared as aquarium fish. However, information on reproductive biology of this fish is rare. To understand the reproductive biology of this fish, a research has been conducted on February-April 2012. There were 123 fishes (102 males and 21 females) captured (52 to146 mm TL and 2 to 68 grams BW). The sex ratio of male and female is 5:1. In each sampling time there were fishes with 1st, 2nd, 3rd and 4th maturity level. The Gonado Somatic Index (GSI) is around 0.01-10.46 %. Fecundity is around 142-10,041 eggs. Relationship between fecundity and TL is weak (R2=0.01), while the relationship between fecundity with BW is strong (R2=0.99). The egg diameter is 0.98-1.00 mm. Histological study shown that the maturity stages of eggs in the ovary is various. In the 1st maturity level, the ovary consists of non vitellogenic eggs (diameter 0.05-0.18 mm). In the 2nd maturity stage, the ovary consists of non vitellogenic and early vitellogenic (0.15-0.44 mm). In the 3rd maturity level, vitellogenic eggs occur (0.28-1.95 mm) and in the 4th maturity level, most of egg in the ovary are mature (0.3-0.5mm), but there are non vitellogenic and early vitellogenic eggs. This evidence indicates that B. hasselti may be a “partial spawner” and it may spawn their eggs throughout the year.Item STRATEGI PENGELOLAAN DANAU BANDAR KAYANGAN KECAMATAN RUMBAI PESISIR KOTA PEKANBARU SECARA BERKELANJUTAN(2019-11) Nurmayani, Nurmayani; Tang, Usman M; Siagian, Madju; Putra, Ridwan MandaThis research was conducted in 2019, in the waters of Lake Bandar Kayangan Samar Valley subdistrict Rumbai Pesisir city of Pekanbaru Riau Province. This study aims to analyze the extent of the tolerance of the quality of Lake Kayangan waters to fish farming (KJA) compared to the Standard Quality of PP No.82 of 2001 and analyze people activities around Bandar Kayangan Lake which led to the polluted waters as a result of daily activities. The method used is an experimental method by observing and measuring sample directly on rearing cages measure 1x1x1 m. Patin fries were stocked at the age of two weeks with the number ( 50 fries ) and 3 months time of rearing. Three units of cages were placed at each station that has been determined and Rumbai Freshwater Cultured Installation pond as control. Data were analyzed descriptively and statistically, the descriptive analysis performed on physical and chemical parameters of water based on PP No. 82 year 2001 and was associated with the growth and survival of Patin fry. Statistical analysis is using Analysis of Variance ( ANOVA ) and completely randomized design ( CRD ) with treatment of 3 times repetition. Growth and survival of Patin fry on each station were quite well where the average growth of absolute weight between 35.43-36.20 grams, the average growth rate of daily weight between 5.602-5.782%, the average of absolute growth inlength between13,61-14.10 cm, the average of daily growth in length between 2.285 - 2.321% and the survival rate between56-79%. The waters of Lake Bandar Kayangan is a waters that are so important for the life of people around Lake Bandar Kayangan especially for fish farming in Keramba Floating Net (KJA). The fish are nila fish, mas and gurami. From the results of interviews of researchers to the community around Lake Bandar Kayangan only certain types of fish are able to survive, this is due to the quality of water at Lake Bandar Kayangan can not be tolerated by other fish. But when the researchers tested the catfish seeds, the catfish still survive.Item TEKNOLOGI BUDIDAYA IKAN BELIDA SEBAGAI SALAH SATU UPAYA PELESTARIAN DARI ALAM(2019-11) Sukendi, Sukendi; Thamrin, Thamrin; Putra, Ridwan Manda; Yulindra, AdeBronze featherback (Notopterus notopterus, Pallas 1769) is one of Indonesia's endemic fish.
