Abstract

ABSTRACTPeriphyton is a sessile microscopic organism that attach on certain substrate. Research aims to determine the type and abundance of periphyton on plastic substrate has been carried out in April-May 2018 in the Sail River. There were three sampling stations, namely S1 (in the upstream), S2 (in the middle) and S3 (in the downstream). Samplings were conducted once/week for a 3 weeks period. The periphyton samples are brushed from the plastic substrates (8x6) cm2. The number of substrates in S1, S2 and S3 were 5, 4, and 3 pieces respectively. Water quality parameter measured were water current, temperature, transparency, pH, dissolved oxygen, free carbon dioxide, nitrate, and phosphate. Results shown that there were 33 types of periphyton present and they were belonged 4 classes, namely Bacillariophyceae (13 species), Cyanophyceae (10species), Chlorophyceae (9 species) andEuglenaphyceae(1species). The abundance of periphyton in the plastic substrate in the S1 was 15,658 cells/cm2, in S2 was 22,095 cells/cm2and in S3 there was 30,799 cells/cm2.The water quality parameters were as follows: water current 0.07-0.69 m/s. transparency 6.03-7.67 cm, temperature 29-300C, dissolved oxygen 4.8-5.7 mg/L, free carbon dioxide13.6-14.6 mg/L, nitrate 0.29-0.38 mg/L, phosphate 0.34-0.54 mg/L. Based on the type of peryphyton present, indicate the trophic state of the Sail River as eutrophic. Keywords: Lotic, sessileorganism, water quality, trophic state

Abstract

ABSTRACTFish Botia is a freshwater fish that have an attractive body colors. Feeding naturallypumpkin flour feed in artificial feed aimed to improve the color quality of clown fish and how long it takes to improve the color. This research was used experimental method with quantutative approach. Research used CRD (Complete Random Design) which consists of 4 treatments with different concentration includes: P0: Positive control, P1: 10%, P2: 15%, and P3: 20%, with 3 replications in each treatments. Parameter in this research are color quality improvements, length and weight accretion.Observation data were analyzed using analysis of variance (ANAVA) α <0.05. The research result showed that feeding the pumpkin flour in artificial diet affected the color improvement of clown fish but did not affect the length and weight of clown fish. The optimal color improvement of clown fish obtained on the treatment with 15% concentration.Keywords: Clown fish, Pumpkin flour, Color quality

Abstract

                                           AbsrtakThis study aims to analyze the form of distribution channel involved in marketing fresh marine fish at Bangliao Oki, Sinaboi Sub District, Rokan Hilir Regwncy. Calculating marketing margins formed from the marketing of fresh marine fish at Bangliao Oki, Calculating the value of marketing efficiency at each marketing agency involved in the marketing process of fresh marine fish at Bangliao Oki Sinaboi Sub District Rokan Hilir Regency. The population in this study were the owner of Bangliao Oki, the fisherman who landed the fish in Bangliao Oki which amounted to 10 people, Agent which amounted to 2 people, 4 people along-along Traders, and 10 retailer merchants. The method used in this research is survey method by doing observation directly to the field (observation) By interviewing fishermen, Agent, retailer and other market players in Sinaboi Rokan Hilir Regency.The results of this study indicate that the pattern of distribution of fish commodities in Bangliao Oki found 2 (two) marketing channels, The most efficient marketing channel is the Marketing I channel involving Retailers, this is due to the marketing costs incurred and the selling price by smaller retailers rather than along-along. The two marketing channels in this study are efficient marketing, this is because the efficiency value is greater than 1 (one), the most efficient marketing is the marketing of the fish cencaru at the marketing institution along-along with the highest efficiency value that is 4.46 and the marketing with value the lowest efficiency is found in Agent marketing agency that is malong fish with efficiency value 2.08. Keywords:Bangliao Oki, Distribution, Marketing Margin, Marketing Efficiency

Abstract

ABSTRACT   Nygaard Index can be used to determine the trophic state of waters. Calculation of this index is based on the number of phytoplankton species in these following groups, namely Desmidiaceae, Myxophyceae, Chlorococcales, Centric diatom and Euglenophyceae. To understand the trophic state of the Tanjung Putus lake, a research has been conducted in February - March 2018. There were three sampling stations, namely station 1 (inlet area), station 2 (the middle of the lake) and station 3 (out let area). In each station there were two sampling points, in the surface and 2 secchi depth. Sampling were conducted 3 times, once/week. Water quality parameters measured were phytoplankton (type and abundance), transparency, temperature, pH, nitrate, phosphate, Dissolved oxygen and free carbon dioxide. Results shown that there were 6 groups of phytoplankton present, namely Desmidiaceae (6 species), Myxophyceae (3 species), Chlorococcales (9 species), Centric diatom (5 species), Cryptophyceae (2 species) and Euglenophyceae (2 species). Water quality parameters were as follows: transparency 77.5-102.5 cm, temperature 30-32 0C, pH 5, nitrate 0.04-0.07 mg/L, phosphate 0.03-0.09 mg/L, Dissolved oxygen 4.1-6.5 mg/L, free carbon dioxide 6.6-11.9 mg/L, Nygaard Index value : 2 – 2.6. Based on Nygard Index, the trophic state of the Tanjung Putus Lake can be categorized as mesotrophic to eutrophic. Keywords: Nutrient, Phytoplankton, Mesotrophic, Eutrophic

Abstract

ABSTRACT                This studywas conducted from May-August 2017 at the Laboratory of Hatchery and Fish Breeding, Marine and Fisheries Faculty University of Riau, Pekanbaru. The objective of this research was to evaluate the intergeneric hybridization between Common carp (Cyprinus carpio L) and Comet goldfish (Carassius auratus). Percentage of Fertilization, hatching, growth, survival in seven days (SR-7), survival rate in thirty days (SR-30),heterosis value, and to know the morphometric and meristic characteristics of hybridized seeds. The method was an experimental method with a Completely Randomized Design (CRD), one factor three times repetition. Spawning is induced breeding using ovaprim hormone with a dose of 0.5 ml/kg. The cross was done by fertilizing the Common carp eggs with Comet goldfish sperm and otherwise the comet fishgold egg is fertilized with Common carp sperm.            The results showed thathybridization was successfully. Heterosis of hybrid results positive to SR-7 parameter while the other parameters are negative. The hybrid ?Cg × ?Cc results have an advantage to FR, HR and SR values while the ?Cc × ?Cg hybrid results excel to absolute weight and length growth parameters.In general, hybrid seeds tend towards the common carp at a ratio of body width, head width, and head length to total length, while towards comet goldfish the character of height to total length compared. Keywords: intergeneric hybridization, growth, morphometric, common carp, comet goldfish

Abstract

Abstract Palabuhanratu Fishing Port is one of the centers of fisheries activities which are currently in the stage of planning to upgrade the status of Ocean Fishing Port. Provision of good facilities and quality services is the most important thing in supporting these activities.However, the problems that exist in fishing ports have been the low level of operation and service of fishing ports caused by internal and external factors of the fishing port. This research was conducted to calculate the operational performance of the fishing port by observing operational activities and fishermen's satisfaction with port services. This research was carried out in May 2018 at the Palabuhanratu Fishing Port, Sukabumi Regency, West Java Province.The results of the analysis carried out showed that the operational performance of Palabuhanratu was included in the category of good enough with a value of 2.72.The achievement of this value is supported by the number of production and frequency of ship visits, each of which has 72.20% and 90.84% success rates, while for the provision of facilities and low service quality, with an average of 16%.This shows that further development of Palabuhanratu must pay more attention to the provision of facilities and quality of service. Keywords: Fisherman Satisfaction, Performance, Operational, Fishing Port
