Abstract. The oysters (Ostreidae) isone of economically important bivalves for urban community in Kuala Gigieng, Aceh Besar District. Presently, the quality and quantity of oyster is decreased over the years by intensive exploitation and water pollution. Therefore, theobjective of the present study was to analyze population structure and habitat condition of oystersin estuary area of Kuala Gigieng, Aceh Besar District, Aceh Province. The sampling was conducted at three locations during August to September 2013. The sampling locations were determined based on anthropogenic activities. A total of two genus of oysters were recorded during the study i.e Crossastrea with four species (C. gigas, C. iridescens, C. angulata, C. virginica) and and Ostrea edulis with one species (O. edulis). The highest density (39 ind m-2)of oysters were found at undisturbed and less pressure environment. The distribution pattern of Ostreidae in the Kuala Gigieng water was clustered where frequency of occurrence wasin small class size of 24 mm to 37.20 mm with optimum harvested of 32.27 mm. The growth of the oysters was relatively slow as shown by the maximum length (Lmaks) that can only reach 37.91-72.81 mm within 0 to 3.42 years. Generally, oysters population structure and habitat conditions in Kuala Gigieng Water was declined over the yeras. Therefore, it is a crucially needed to plan a management strategy for oysters with regulation on fishing, shellfish farming and waste disposal regulation to ensure the oysters population remains sustain.Keywords : Environment factors; fishing, growth; Kuala Gigieng; Oyster; population structureAbstrak. Tiram daging (Ostreidae) merupakan salah satu kerang yang memiliki nilai ekonomi penting bagi masyarakat Kuala Gigieng. Namun, kualitas dan kuantitas tiram menurun akibat eksploitasi dan pencemaran perairan. Penelitian ini bertujuan untuk menganalisis struktur populasi dan kondisi habitat tiram di perairan estuaria Kuala Gigieng Kabupaten Aceh Besar, Provinsi Aceh. Sampling dilakukan pada tiga lokasi selama bulan Agustus hingga September 2013.Hasil penelitian menunjukkan bahwa terdapat dua genus tiram di perairan Kuala Gigieng yaitu Crassostrea dan Ostrea dengan total 5 spesies (C. gigas, C. iridescens, C. angulata, C. virginica and O. edulis). Kepadatan tertinggi berada pada lokasi yang tekanan penangkapan dan lingkungannya yang rendah. Pola penyebaran tiram daging di Kuala Gigieng cenderung mengelompok. Frekuensi ukuran selang kelas tiram terbanyak yang ditemukan yaitu 24-37,20 mm dengan ukuran layak tangkap yaitu 32,27 mm. Pertumbuhan tiram daging di Kuala Gigieng tergolong lambat, hal ini ditunjukkan dengan panjang maksimal (Lmaks) yang mampu dicapai kerang ini hanya 37,91-72,81 mm dalam waktu 0-3,42 tahun. secara keseluruhan, struktur populasi tiram daging dan kondisi habitat di Kuala Gigieng mulai menurun. Oleh karen itu, diperluka pengaturan pengelolaan sumberdaya tiram dengan melakukan pengaturan penangkapan, budidaya tiram, dan pembuangan limbah agar sumberdaya tiram di Kuala Gigieng tetap lestari.Kata kunci : Faktor lingkungan; Kuala Gigieng; penangkapan; pertumbuhan; struktur populasi; tiram daging,

Giant freshwater prawn is a native Indonesian freshwater prawn, which has the largest body size among other freshwater prawn. Efforts to increase the production of giant prawns can be done by genetic improvement of the parent. The main basis for conventional genetic improvement of giant freshwater prawns is availability of morphological variation information. This study is to determine the morphological variations of the giant prawn broodstock of Siratu, GIMacro, Mahakam, and Bengawan Solo populations which are cultured in Unit Kerja Budidaya Air Payau Balai Budidaya Udang Galah (UKBAP BBUG) Samas. Through this research it is expected to determine the broodstock with a profitable character that is able to produce hybrids with profitable characters as well. Baseline morphometrics were observed from the ratio of cephalothorax: abdomen length, ratio of carapace: rostrum length and ratio of carapace: abdomen length. Morphological variations were observed using 58 characters which included morphometric, meristic and morphological characters. The results showed the largest ratio of cephalothorax and abdomen average length owned by Bengawan Solo population, while the largest ratio of carapace and abdominal average length owned by Mahakam. The highest morphological variation is owned by Mahakam with 52% similarity. The lowest morphological variation is owned by GIMacro and Siratu populations with 80% similarity. The giant prawn broodstock which is expected to produce hybrid with profitable character is the broodstock from Bengawan Solo population.Keywords: Giant freshwater prawn, Morphological variation, SiratuGIMacro, Mahakam, Begawan Solo ABSTRAKUdang galah merupakan udang air tawar asli Indonesia, yang memiliki ukuran tubuh terbesar di antara udang air tawar lainnya.

Global warming is caused by increased carbon emissions into the atmosphere resulting from burning oil, gas, and other fossil fuels. Subsequently, the carbon gas enters the waters through a diffusion process facilitated by the concentration of gases in the air, which is higher than in the waters. The outcome of this process is a decrease in water acidity, leading to a lower pH, which can disrupt the life of aquatic biotas. Therefore, this study aims to analyze the effect of decreasing of pH on the growth, survival, and physiological conditions of barramundi (Lates calcarifer). To achieve this objective, seven pH levels were tested, namely pH of 7.24 (control), pH 6.74, pH 6.24, pH 5.74, pH 5.24, pH 4.74, and pH 4.24. Every treatment was performed with four replications, and the fish was reared for 30 days in the respective tested pH. The reared madia is sea water with a salinity of 22 ppt. The experiment was conducted in the laboratory of fish breeding Faculty of Marine and Fisheries, Universitas Syiah. The results showed that a decreasing in pH had a significant effect on the growth performance and hematological condition of barramundi (P0.05), but its had no significant effect on survival (P0.05). The experimental fish could survive at pH 4.24, but their growth and hematological conditions were disrupted below 6.24. Therefore, it was concluded that the lower threshold value of pH for barramundi was 6.24.Keywords:Global warmingOcean aciditypHFisheries productionPhysiological disturbance

Cellulolytic bacteria that produce cellulase enzymes play an essential role in degrading cellulose in their habitat. The presence of cellulolytic bacteria strongly supports the fertility and productivity in mangrove waters. The objectives of the study are to analyze the activity of cellulase enzyme qualitatively through the cellulolytic index and quantitatively through the activity and specific activity of the cellulase enzyme from bacteria isolated from the water of mangrove ecosystems in Aceh Province. The qualitative experiment of enzyme activity was carried out at the Microbiology laboratory SKIPM Aceh, and a quantitative experiment of enzyme activity was conducted at the Microbiology Laboratory, Biology Department, IPB. Isolation of cellulolytic bacteria isolated from mangrove water used Carboxy Methyl Cellulose (1% CMC) selective media and carried out by spread plate method. The ability of bacteria to produce cellulase was tested qualitatively using the spot technique, this test was carried out using 1% Congo Red. Furthermore, the quantitative testing of cellulase enzymes activity adopted the DNS spectrophotometric method. The specific activity of the cellulase enzyme can be determined by using the Lowry method. There were 21 isolates that had a clear zone and had the ability to produce cellulase enzymes from 49 isolates that were successfully purified. The highest cellulolytic index (CI) produced using BAM421 isolate with the value of 5.50 was included in the high category, followed by BAM326 and BAM132 isolates, with values of 1.55 and 1.05 were categorized into the medium category. The other isolates were in the low cellulolytic index category. The isolate with the highest CI value was further tested using the quantitative enzyme activity test. The highest cellulase enzyme activity of BAM421 occurred at 24hr (0.0029 U/ml). The highest specific cellulase activity of BAM421 was at 24hr with the value of 0.210 U/mg. The result concluded that the qualitative test showed CI values can be categorized into low, medium, and high. Moreover, the value of the quantitative assay described that the cellulase enzyme and the specific enzyme activities of the bacteria were low in the study area.Keywords:Cellulolytic indexQuantitative testMangrove watersCellulase enzymeMicroorganismTRANSLATE with x EnglishArabicHebrewPolishBulgarianHindiPortugueseCatalanHmong DawRomanianChinese SimplifiedHungarianRussianChinese TraditionalIndonesianSlovakCzechItalianSlovenianDanishJapaneseSpanishDutchKlingonSwedishEnglishKoreanThaiEstonianLatvianTurkishFinnishLithuanianUkrainianFrenchMalayUrduGermanMalteseVietnameseGreekNorwegianWelshHaitian CreolePersian // TRANSLATE with COPY THE URL BELOW Back EMBED THE SNIPPET BELOW IN YOUR SITE Enable collaborative features and customize widget: Bing Webmaster PortalBack//
