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 Cisadanes 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 Cisadanes 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 Cisadanes River headwater support macroinvertebrate life and are in accordance with RCC.Keywords:EcologyMacroinvertebrateNational ParkRiparianRiver

Ikan manyung (Arius thalassinus) merupakan salah satu komoditas perikanan demersal bernilai ekonomis penting yang banyak didaratkan di Pelabuhan Perikanan Pantai (PPP) Sungai Rengas, Kalimantan Barat. Produksi ikan manyung menunjukkan fluktuasi setiap tahunnya sehingga diperlukan kajian stok untuk mendukung pengelolaan berkelanjutan. Penelitian ini bertujuan untuk menganalisis kondisi stok ikan manyung melalui perhitungan hasil tangkapan per satuan upaya (Catch Per Unit Effort/CPUE), potensi maksimum lestari (Maximum Sustainable Yield/MSY), tingkat pemanfaatan (TPc), serta jumlah tangkapan yang diperbolehkan (Total Allowable Catch/TAC). Data yang digunakan berupa data sekunder produksi tangkapan dan upaya penangkapan dengan jaring insang selama periode 2015–2024. Analisis dilakukan menggunakan model surplus produksi Schaefer. Hasil penelitian menunjukkan nilai MSY sebesar 15.338 kg/tahun dengan upaya optimum sebesar 88 unit/tahun. Tingkat pemanfaatan ikan manyung rata-rata sebesar 89,18% yang tergolong padat tangkap, sedangkan TAC ditetapkan sebesar 12.270 kg/tahun (80% dari MSY). Beberapa tahun menunjukkan kondisi pemanfaatan melebihi TAC, yaitu tahun 2017, 2020, 2022, dan 2024, sehingga berpotensi mengalami overfishing. Hasil penelitian ini menegaskan perlunya pengendalian upaya dan penerapan kuota tangkapan berbasis TAC guna menjaga keberlanjutan stok ikan manyung di PPP Sungai Rengas.

Samih River, located in Kumpang Tengah Village, Sebangki District, Landak Regency, is widely utilized by the local community for various activities, including excessive fishing. This activity has caused a decline in the population of economically valuable fish species, namely the kelabau fish (Osteochilus melanopleura). This study was conducted to analyze the feeding habits and diet of kelabau fish in Kumpang Tengah Village, Sebangki District, Landak Regency, from January to March 2025, consisting of three research stations based on environmental conditions. Kelabau fish were collected using gill nets and fishing lines, and data analysis was carried out using the Index of Preponderance (IP), the Index of Stomach Content (ISC), and relative gut length. The results showed that the main food of kelabau fish was phytoplankton with an IP value of 98.25%, followed by supplementary foods such as aquatic plants and zooplankton with IP values of 1.74% and 0.014%, respectively. Kelabau fish are herbivorous, as indicated by the relative gut length (ISC) values found: 1.232% at station three, 1.081% at station two, and 0.980% at station one.

Ikan Toman (Channa micropeltes) merupakan salah satu jenis ikan air tawar yang banyak dikonsumsi oleh masyarakat kerena memiliki nilai gizi dan ekonomis yang tinggi. Ektoparasit merupakan parasit yang menyerang ikan di bagian luar pada tubuh ikan. Pada dasarnya infeksi ektoparasit pada ikan dapat menimbulkan kerugian. Meskipun kerugian tersebut tidak sebesar kerugian akibat infeksi organisme patogen lain seperti virus dan bakteri, infeksi ektoparasit dapat menjadi salah satu faktor predisposisi bagi infeksi organisme patogen yang lebih berbahaya. Penelitian ini bertujuan untuk mengetahui jenis ektoparasit yang menyerang ikan toman baik dari tangkapan alam maupun budidaya di Desa Salwa Kabupaten Sambas. Metode yang digunakan dalam penelitian yaitu metode Purposive Sampling dan Random Sampling yang dilakukan di setiap stasiun. Hasil pengamatan selama penelitian yaitu jenis ektoparasit yang ditemukan ada dua jenis ektoparasit yang menyerang ikan toma yaitu Dactylogyrus sp pada organ insang dan Argulus pada kulit ikan. Prevalensi ikan toman stasiun I yaitu 15% termasuk kategori sering dan infeksi sering, stasiun II yaitu 10% termasuk kategori sering dan infeksi sering dan stasiun dan IV yaitu 5% termasuk kategori terkadang dan infeksi terkadang sedangkan pada kolam budidaya stasiun I yaitu 80% termasuk kategori biasa dan infeksi biasa, stasiun II dan III yaitu 50-60% termasuk kategori sering kali dan infeksi sangat sering, dan stasiun IV 30% termasuk kategori umumnya atau infeksi biasa. Intensitas stasiun I, II, III dan IV pada tangkapan alam dan budidaya berkisar antara 1-2 ekor/ind, dan termasuk dalam kategori infeksi rendah.Kata Kunci: Desa salwa, Ektoparasit, Ikan Toman

Fish are one of the important components in the aquatic ecosystem, therefore we need important information, one of which is through a bioecological approach, one of which is the bioecology of black tilan. Black spiny eel fish (Mastacembelus unicolor) living in the Sangah River, Banying Village, Landak Regency has never been researched on bioecology. The purpose of this study is to analyze longitudinal distribution, feeding habits, population structure and its relationship with aquatic habitat. The research was conducted March to May 2024 at 3 sampling station, namely Station I, Station II, and Station III. Sampling was carried out using trawlers, arrows and fishing rods. Water quality measurements are carried out in-situ at the time of fish sampling. The number of black spiny eel obtained was 32. The results of the study show that the distribution is spread across the three stations with different abundances. food habits are classified as carnivores with the RGL of station I of 0,286, station II of 0,284, station III of 0,302. The main food consisted of the food group of platyhelmintes with a percentage of 77.59%, the food group of crustaceans and nematodes as complementary foods with a percentage of 9.80% and 8.33%, then the food group of insects, annelids, phytoplankton and plants was supplementary food with a percentage of 4%. The relationship between the length weight of black spiny eel with the regression equation y = 3,36x "“ 3,1945 shows that the growth pattern of black tilan is allometric positive and the condition factor value is 0.000206 which indicates that the black spiy eel population is in poor condition. The average water quality value of each station in Sungai Sangah is DO in the range of 5,6-6,4 mg/l, temperature 27,9-28,4 OC, pH 6,4-6,6, current velocity 21,8-32,6 m/s, brightness 66,7-67,1 cm and depth range 99-120 cm.
