Togok is one of the fishing gear that is operated in Kuala Tungkal, Tanjung Jabung Barat Regency, this fishing gear is in the form of a conical net body whose arms are tied to two poles and the success of catching it relies on currents, togok fishing gear is used by Kuala Tungkal fishermen to catch rebon shrimp (Acetes japonicas) but in operation, there are many other types of catch. This study aims to determine the main catch, bycatch, and discards and to determine the size as well as the number of togok catches. This research was conducted on April 5 – July 10, 2021. This research was conducted using experimental fishing methods, namely by conducting direct operations with local fishermen. The results of the study that the percentage of the catch of the main catch by 28%, bycatch 51%, and discard 21%. For the size of the catch of togok species of shrimp (crustacean), there are many sizes that have reached maturity or are suitable for catching while in the catch of fish species there are many sizes that are not yet mature. And for the number of catches in the catch togok main catch amounted to 550800 tail, the catch of the bycatch 79281 fish, and the catch of the discard 10186 fish.

Artocarpus stems (Artocarpus sp.) and Carex grass (Carex sp.) have not been applied to fishing gear materials. The fibers produced made into a rope, where this rope is used to absorption and sinking speed test in fresh water and sea water.The absorption of Artocarpus stems rope was 320.30% and 282,60% in fresh water and sea water. Meanwhile for sinking speed have a 5,78 cm/s and 5,08 cm/s for fresh water and sea water. For the Carex grass rope, the absorption in fresh water and sea water was 287,67% and 218,02%. Sinking speed value 2,97 cm/s and 2,67 cm/s for fresh water and sea water. The value of absorption and sinking speed in fresh water is higher than in sea water for both types of rope.

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).

Penelitian ini bertujuan untuk mengembangkan ekowisata memancing yang berkelanjutan di kawasan mangrove Desa Buruk Bakul, Kecamatan Bukit Batu, Kabupaten Bengkalis, Provinsi Riau, melalui pendekatan partisipatif dan edukatif. Metode yang digunakan terdiri dari tiga tahap: persiapan, pelaksanaan, dan evaluasi. Tahap persiapan melibatkan identifikasi masalah, koordinasi dengan stakeholder, studi tentang kebutuhan wisatawan, dan persiapan logistik. Tahap pelaksanaan fokus pada edukasi dan pemberdayaan masyarakat melalui pretest, penyuluhan, diskusi interaktif, dan post-test. Tahap evaluasi dilakukan dengan menganalisis peningkatan pemahaman peserta dan mengumpulkan saran untuk pengembangan lebih lanjut. Hasil kegiatan menunjukkan peningkatan signifikan dalam pemahaman peserta mengenai ekowisata memancing. Setelah penyuluhan, 76,47% peserta menyatakan mengerti materi yang disampaikan, meningkat dari pemahaman awal. Partisipasi aktif peserta tercermin dari saran konstruktif seperti pengembangan spot memancing, peningkatan fasilitas, dan penerapan alat tangkap ramah lingkungan. Meskipun keterlibatan langsung dalam kegiatan ekowisata memancing masih rendah, kesadaran akan potensi ekonomi dan pentingnya konservasi lingkungan telah meningkat. Kegiatan ini berhasil membangun fondasi untuk pengembangan ekowisata yang berkelanjutan di Desa Buruk Bakul.
