Abstract

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,

Abstract

Intensive shrimp ponds are characterized by the high stocking density of shrimp and artificial feeding and are equipped with an irrigation network system. The purpose of this study was to analyze the intensive L.vannamei pond with an irrigation system based on Vibrio spp. distribution to determine environmental quality degradation in terms of the treat of pathogenic bacteria. This study was carried out for one production cycle from March toJuly 2021 in an intensive shrimp farm in Sarjo Village, Pasangkayu Regency, West Sulawesi. The parameters analyzed in this study consisted of Total Bacterial Count (TBC), Total Vibrio Count (TVC), yellow and green colony Vibrio spp. in water using the spread plate method. Water samples for bacterial analysis were taken from 1) source water: (a) surface (0–50 cm depth) and (b) pump mouth; 2) treatment pond; 3) aquaculture pond; 4) Waste Water Treatment Ponds (WWTP); 5) outlet (before discharge into public waters). The results showed that the distribution of bacteria from seawater to WWTPs pond still increased the abundance of Vibrio spp., although the abundance of Vibrio spp. is still safe or below the maximum limit of 104 CFU/mL. Distribution of Vibrio bacteria in Intensive L.vannamei Pond Sarjo Village, West Sulawesi gave a relatively good pond performance because it was characterized by an abundance of Vibrio bacteria in the pond irrigation system from inlet to outlet which was still below the maximum limit and high pond productivity.Keywords:Intensive shrimp pondPathogenicVibrio spp.Pond performanceAquaculture

Abstract

River Continuum Concept (RCC) is an approach that describes the dynamic changes in the river system, the changes that occur are physical conditions (order of the river, canopy cover, and land use) and also the structure and function of communities. Functional feeding groups (FFG) of macroinvertebrates are related to environmental gradients in aquatic systems, including river ecosystem attributes. This study aimed to correlate the function of the macroinvertebrate communities with Cisadane’s River headwater conditions based on RCC and also to estimate the attributes of the river ecosystem. This research was conducted in the headwaters of the Cisadane River, West Java-Indonesia. One of Cisadane’s River headwaters was located in Mount Halimun-Salak National Park. Macroinvertebrates were collected from four sites inside the park (stations 1, 2, 3, and 4) and from two sites outside the park (stations 5 and 6). Collections were made twice a month, from April to June 2015 using a Surber sampler. The results showed that shredders and predators were relatively higher at stations inside the national park than at those outside the national park. While scrappers and collectors at stations located inside the national park were relatively lower than at stations outside the park. The value of the P/R ratio showed that all of the stations were heterotrophy. CPOM/FPOM ratio represents that shredder availability is high enough at stations inside the national park. While TFPOM/BFPOM ratio is slightly below the normal threshold value. HSI showed that the condition of the riverbed substrate stability is quite good. Composition changes of macroinvertebrates showed suitability with RCC. River ecosystem attributes and abiotic stream characteristics of Cisadane’s River headwater support macroinvertebrate life and are in accordance with RCC.Keywords:EcologyMacroinvertebrateNational ParkRiparianRiver

Abstract

Microalgae are cultured as natural feed for the cultivation of mollusks, crustaceans (early larval stages), and zooplankton. Diatoms are phytoplankton groups commonly used as feed, one of which is Chaetoceros muelleri. This study aims to identify the optimal nitrate concentrations and light level (irradiance) for the growth rate of C. muelleri. Culture was placed in nitrate 1,330; 5,305; and 27,030 mg/L (N1, N2, N3, respectively); and light 50, 100, and 150 µmol/m2/s, with three replications for each treatment. The response variable observed was the growth rate of C. muelleri and nitrate uptake. Each nitrate treatment resulted in a significant difference in the growth rate of C. muelleri (LSD, p  0.01). The N3 treatment produced the highest growth rate (average 0,188-0,193 cells/day), while N1 produced the lowest specific growth rate (average 0,149-0,157 /day). In light treatment, a significant difference was only seen in the light levelof 150 µmol/m2/s (LSD, p 0.05) which produced the highest growth rate (average 0.157-0.193 cells/day), especially in the nitrate N1 and N2. Meanwhile based on the significance test, the interaction between nitrate and light treatment was not significant.Keywords: Chaetoceros muelleri; Growth rate; Irradiance; Nitrate
