However, study on composition of mitochondrial DNA nucleotide as a part of study on genetic characterization of stripped snakehead fish in Indonesia is poorlyunderstood. Genetic characterization of stripped snakehead is important to obtain data information that can be applied for breeding and conservation program. Therefore, the objective of this study was to determine the 16S and COI mitochondrial DNA nucleotide of stripped snakehead collected from Lake Sentani, Jayapura, Papua. Method used in this research is PCR method using primer 16Sar and 16Sbr for 16S mitochondrial gene, and FishF2 and FishR2 for COI mitochondrial gene. The results showed that composition of 16S mtDNA nucleotide from 616 bp was T=21.92%, C=25.49%, A=30.19%, dan G=22.40%, whereas composition of A+T=52.11% and G+C=47.89%. In addition, composition of COI mtDNA nucleotide from 705 bp was T=29.93%, C=28.65%, A=24.26%, and G=17.16% while composition of A+T=54.48% and G+C=45.52%. Data of 16S and COI mitochondrial DNA nucleotide composition of the stripped snakehead collected from Lake Sentani gained in this study are to be expected to complete genetic information of the fish species which is useful to improve breeding program of this fish species in the future.","PeriodicalId":33003,"journal":{"name":"Jurnal Perikanan Universitas Gadjah Mada","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45665842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the main problem faced by the cultivators is the limited stock of seeds, both in terms of quality and quantity. Selection is one method that is expected to increase the rate of seaweed growth quickly, cheap, easy, bulk, and sustainable.This study aims to determine the effect of selection on the growth of seaweed so that it can be done superior seed production for cultivation purposes. Seaweed cultivation was done in Kulu Village, Wori District, North Minahasa Regency, North Sulawesi by using long line method in April-June 2015. Selection is based on the daily growth rate parameter (DGR) and the selection method refers to the selection protocol that has been developed on K. alvarezii seaweed. Results showed that DGR of selection seedlings were higher (P <0.05) compared to controls, in which DGR of selection reached 5.87%/day, while DGR of control was 1.89%/day. From three seed production cycles (G-1 - G-3), the average DGR resulted from the selection was 5.53%/day and control 2.19%/day. Carrageenan content of selection result is relatively higher (47.66%) than control (31.28%) with mean for three cycle (G-1 - G-3) that is 43.55% for selection and 33.20% for control. Water quality (temperature, salinity, nitrate, phosphate) during the study is still within the appropriate range for seaweed growth. Therefore it is concluded that with the application of the method of seaweed selection can increase the daily growth rate and carrageenan content of seaweed K. alvarezii which directly affects the increase of production both in quantity and quality.","PeriodicalId":33003,"journal":{"name":"Jurnal Perikanan Universitas Gadjah Mada","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45998249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was designed using Completely Randomized Design (RAL), with two replications. Each fish was kept in six concrete tanks with dimension 2x2x1 m³ and 60 cm water level. Water source were from wells. Commercial pellet feed was given in three times daily ad libitum. Water samples were filtered and two individual fish were collected for plankton samples from pond water and alimentary canal, respectively, every two week, simultaneously with water quality measurements. Plankton samples were preserved using 5% formaldehyde and was observed under a compound light microscope with 100x magnification. The amount of plankton in the alimentary canal was converted to volume. Data were analyzed descriptively. The result showed that the volume contents proportion of plankton in the alimentary canal was less than 1%. The volume of plankton proportion in the alimentary canal of red nile were found the most than other fish. Each fish had the same preference of plankton of Lepocinclis and Scenedesmus, but different from other species of plankton. The plankton that utilized by giant gouramy were Crucigenia, Diadesmis and Navicula, whereas walking catfish was Pediastrum, and red nile was Microcystis. The plankton that preferred by giant gouramy were Crucigenia, Oscillatoria, Splirullina, and Synedra, walking catfish was Navicula, while red nile were Chrysamoeba and Tintinnidium.","PeriodicalId":33003,"journal":{"name":"Jurnal Perikanan Universitas Gadjah Mada","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42654695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
