Abstract

Marine fish community is very sensitive to environmental changes. So the number of species, abundance, and biodiversity index can be used as a reference to assess the quality of the aquatic environment. The aim of this study was to describe fish biodiversity in Belitung Timur, Bangka Belitung Islands, Indonesia. Three islands were visited i.e. Pekandis Island, and Keran Island, Gosong Semut (Gosong refers to sandbar) for reef fish survey and for the economical fish study we also visited fisheries landing sites (i.e. Teluk Pering, Tanjung Batu Pulas, and Pantai Burung Mandi). The underwater visual census was used for in situ surveys of reef fish, and the fish species landed in fisheries landing site also been checked. Forty-two families of economical fish that had been landed by local fishermen were identified, and ten families of reef fish were found in reef systems of research location. A total of 10 families were recorded from three islands in Belitung Timur Regency. In addition, 42 families of commercial fish were also observed in fish landing sites from the coastline of Belitung Timur Regency, Bangka Belitung Islands.

Abstract

A first survey  on a community marine species in  river of Mahakam East Kalimantan was performed in December 2015 and May 2016. Fish samplings were carried out from two locations the lower and the middle part of Mahakam. Whilst hydrometric observation of current velocity, water depth and tide was measured not only at the locations but also along the river from 2013 to 2017, tide was only observed in the lower part of Mahakam.  However, marine fish species were recognized to reach up the middle part of Mahakam, 230 km from coastline.  To describe a community fish structure and its dissimilarity of the two surveyed locations, diversity and bray Curtis index were applied.  Almost 15 marine fish species identified in river of Mahakam was demersal fish and index of the similarity of marine fish community between the locations only 0.106.

Abstract

Increased human activity towards the water bodies will change the condition of water quality. Case study in Langsa, Aceh, It was found that an increase in Some physical parameter (TSS) that exceeds the value determined in PP 82 of 2001 (Indonesian government standard). The high value of TSS in Station 2 and Station 3 indicates that the sediment loading to the water body is high, especially in Station 3, where the TSS concentrations far exceed the standard. Activity of type C surface mining materials tends to affect the brightness, turbidity, depth and TSS. Water conditions with low pH were also found in this study. In location studied no EPT larvae were found Keyword: Langsa, Water Quality, Stream, Total Suspended Solid, Anthropogenic Activity

Abstract

Bagan tancap merupakan alat tangkap ikan kategori jaring yang banyak digunakan di Kalimantan Timur. Bagan tancap dioperasikan pada malam atau siang hari sesuai dengan kebutuhan dan situasi di daerah tersebut. Seperti di perairan Lamaru, setiap operasi jaring dilakukan ± 2-3 kali hauling atau jaring yang biasanya dilakukan sebelum tengah malam (21.00-23.59 WIB), tengah malam (00.00-02.59 WIB) dan setelah tengah malam (03.00-06.00 WIB). Penelitian ini bertujuan untuk menganalisis perbedaan waktu angkut tancap Bagan terhadap hasil tangkapan di Perairan Lamaru Kota Balikpapan. Pengumpulan data dilakukan tiga kali sehari dengan menggunakan metode purposive sampling dengan 3 periode pengambilan sampel untuk setiap pengambilan data. Hasil yang ditemukan tangkapan diambil sebelum tengah malam dengan rata-rata 5,52 kg, pada tengah malam jumlah tangkapan rata-rata 3,90 kg, sedangkan setelah tengah malam angka rata-rata yang didapat adalah 7,36 kg. Dari hasil tersebut dapat disimpulkan bahwa perbedaan waktu angkut menunjukkan perbedaan hasil yang signifikan terhadap hasil tangkapan, dan waktu angkut bagan yang paling optimal adalah setelah tengah malam.
