Osteochillus hasselti was commonly inhabit the Lubuk Siam Lake. A research aims to understand the standing stock of O. hasselti in that lake was conducted in July to August 2018. The fish was sampled everyday for 10 days in July and 10 days in August, in 3 sampling points (in the inlet area, in the middle of the lake, and the outlet) using gill nets. The standing stock was analyzed using Leslie method. Results shown that the initial population (No) of the fish was 315 kg and the final population (Nt) was 301 kg and the exploitation level was 8%. The water quality parameter shown that temperature was 27-28oc, clarity 63-95 cm, pH = 6 and dissolved oxygen was 5.32–5.40 mg/L. Data obtained indicate the water quality in the Lubuk Siam Lake is good and it is able to support the life of O. hasselti

This research was conducted for five months from May to September 2022 which is located in Sungai Apit District by taking six (6) villages as sampling locations from the eight (8) existing villages. This research was conducted for five months from May to September 2022 which is located in Sungai Apit District by taking six (6) villages as sampling locations from eight (8) existing villages. The research objective was to calculate and assess the adaptive capacity of mangrove ecosystems in Siak District, Siak Regency. Measurement of the adaptive capacity of mangrove ecosystems is carried out by analyzing six parameters, namely Mangrove Dimension Index (IDMg), Dominant Mangrove Species, Mangrove Tree Density, Number of Mangrove Species, Substrate Type, Ecosystem Distance from Settlement. The value of the adaptive capacity of mangrove ecosystems is in the range of 0.0-1.0, with five capacity categories namely "very low, low, medium, high, and very high". The results showed that the number of mangrove species found growing on the coast of Sungai Apit District was 19 species belonging to 10 families and 12 genera, distributed in the "low" category with a mangrove dimension index (IDMg) value of 0.6 (0.4<IDMg <0.8).Dominant species from the Rhizophoraceae family with a density classified as "high". The adaptive capacity of the mangrove ecosystem at the study site is classified as "high" with an adaptive capacity value of 0.67 (0.6 ≤ KPMg ≤ 0.8).

Sawah Village Swamp is one of the swamp waters in Kampar Utara District, Kampar Regency, Riau Province, as a habitat for fighting fish. This study aimed to determine the existing conditions of water quality, type, and population of fighting fish. The research method used is the survey method. Determination of sampling points using a purposive sampling method. The data results measuring the existing conditions of the quality of swamp waters in Sawah Village can still support aquatic organisms, especially fighting fish. The types of fighting fish found during the study consisted of 4 types: Trichopsis vittata, Betta akarensis, Betta waseri, and Betta imbellis. The number decreases if fishing efforts continue to be increased.

Danau Panjang is a natural lake located in Lubuk Siam Village. The variety of activities in Danau Panjang can affect phytoplankton biodiversity. Phytoplankton is an important factor for the life of fish and all kinds of biota that live in water as primary producers. The presence of phytoplankton will determine the quality and condition of a body of water. Danau Panjang, as one of the oxbow lakes, currently rarely has any additional discharge from the main river, so it is feared that phytoplankton diversity will be low. This study aims to determine the type and abundance of phytoplankton and phytoplankton biodiversity and the results of the analysis of environmental factors on phytoplankton biodiversity in Danau Panjang. Phytoplankton biodiversity and water quality parameters consisting of temperature, brightness, depth, pH, CO2, DO, nitrate, and phosphate were observed in September-October 2023. Phytoplankton samples and water quality measurements were taken at three sampling points, three times with an interval of two weeks. Phytoplankton abundance ranged from 2383-7098 cells/L, and 10 phytoplankton classes were found. Phytoplankton biodiversity in Danau Panjang illustrates a relatively stable condition. The species richness index in Weeks 1, 2, and 3 ranged from 3.51-5.52 in the good category. The diversity index in Weeks 1, 2, and 3 ranged from 2.06-3.82, with a high level of diversity. The dominance index in Weeks 1, 2, and 3 ranged from 0.12-0.38, indicating that there was no dominant species. The uniformity index in Weeks 1, 2, and 3 ranged from 0.39-0.69, where uniformity was in balance. In general, the water quality in Weeks 1, 2, and 3 is not much different and is favorable for phytoplankton growth when viewed from the quality standards of class III of PP No. 22 of 2021

Penelitian tentang Struktur Komunitas Gastropoda Pada Ekosistem Lamun Perairan Pantai Binasi Kabupaten Tapanuli Tengah Provinsi Sumatera Utara dilakukan pada bulan Mei-Juni 2023. Penelitian ini bertujuan untuk mengetahui struktur komunitas gastropoda pada ekosistem lamun di perairan Pantai Binasi Kabupaten Tapanuli Tengah Provinsi Sumatera Utara yang meliputi Kerapatan lamun, kepadatan gastropoda, indeks keanekaragaman, indeks keseragaman dan indeks dominansi gastopoda. Metode yang digunakan dalam penelitian yaitu metode survei. Pengambilan sampel gastropoda dan lamun menggunakan metode purposive sampling. Dari hasil penelitian diperoleh 8 jenis gastropoda dengan nilai kepadatan 8,33-13,12 ind/m2. Berdasarkan hasil analisis diperoleh nilai indeks Keanekaragaman (H’) berkisar 2,459-2,729 dikategorikan sedang, indeks keseragaman (E) berkisar 0,876-0,909 dikategorikan tinggi dan indeks dominansi berkisar 0,176-0,216 yang berarti tidak ada jenis gastropoda yang mendominansi di Perairan Pantai Binasi Kabupaten Tapanuli Tengah. Dari hasil regresi sederhana ternyata didapatkan kekuatan hubungan kerapatan lamun dengan kepadatan gastropoda dikategorikan kuat.
