Abstract

The Sail River is one of the largest tributaries of the Siak river in the city of Pekanbaru, which is located around a residential area. This study aims to determine the content of heavy metals (Cd, Fe, Cr, Cu) in water and sediments in the Sail River. The study was conducted in December 2017 - January 2018 using the survey method. The samples obtained were taken and analyzed at the Laboratory of Marine Chemistry at the Faculty of Fisheries and Marine Universitas Riau using Atomic Absorption Spectrophotometry (AAS). The heavy metal content in water for Cd is equal to the quality standard threshold; Fe, Cr, and Cu in water in the Sail river exceeds the water quality standard threshold in PP No. 82 of 2001. While the heavy metal content in the sediment for Cd, Fe, Cr, and Cu are still below the  CBSQG 2003 quality standard limits and ANZECC / ARMCANZ 2013 (revised).

Abstract

In recent years, many net cages for aquaculture activities, especially for culturing Wallago leeri and Mystus numerus are placed along the Kampar River, especially in the Buluhcina Village. The remain of fish feed, namely rotten chicken flesh have polluted the water. This study aimed to identify the cage culture profile; to analyze the feasibility of the business and the carrying capacity of the environment. This research was conducted in August 2016 – March 2017. There are three observation stations,  Station 1 (before the cage area), Station 2 (the cage area) and Station 3 (after the cage area). Sampling was conducted once. The length of the river is 1.4 Km and 594 single unit net cages are placed along 1,2 Km river. Among the cages, 570 units (96% )are used to the culture of W. leeri,  19 units (3.2%) for M. numerus and the rest, 3 units are for rearing Pangasius sp. and Oreochromis niloticus (1 unit). The carrying capacity of the waters is 496.1 tons/year. The current annual production of W. leeri is 228 tons/year, it is less than the maximum potency.  It is predicted that the culture can be increased by 258.5 ton/year or 646 cages. The recent RCR value is 1.120, indicates that this business is profitable and it could be continued.

Abstract

Ikan tambakan (Helestoma sp.) merupakan ikan air tawar yang bernilai penting. Belum adanya penelitian terkait pola pertumbuhan dan faktor kondisi ikan tambakan (Helestoma sp.) di Danau Panjang. Pengambilan sampel dilaksanakan pada bulan Oktober 2022 dengan menggunakan alat tangkap berupa jaring, pancing, dan perangkap di Danau Panjang Desa Lubuk Siam, Riau. Data dianalisis menggunakan aplikasi Ms. Excel dari hasil analisis pola pertumbuhan ikan (n=32) menunjukan nilai a = 0,0079 dan nilai b = 3,3778, R2 sebesar 0,9554. Pola pertumbuhan ikan tambakan di Danau Panjang bersifat alometrik positif. Faktor kondisi ikan tambakan relatif baik dengan nilai berkisar 0,769 hingga 1,192.
