Status of mangrove ecosystem on Liong River, Bengkalis Island, Riau Province, is currently in a condition that tends to get a stressed doe to 60% of indigenous people living around mangroves are loggers. Series Landsat is used as recording data to map the mangrove and to see the changes in the region. This study aims to map changes in mangrove ecosystems from 1990 - 2017 using the OBIA method. The field observation was done using Unmanned Aerial Vehicle (UAV). The results showed that mangrove area has decreased every year. It was caused by anthropogenic and natural factors. Approximately 4.2% of mangrove decrease from 1990 to 2017 and mangrove highest exploitation occurred in 2007 with a decline of 31.5%.

Tapanuli Tengah and Sibolga are one of the producers of small pelagic fish in the waters of West Sumatera. Spatial information on estimating the potential of small pelagic fish in the waters of Central Tapanuli and Sibolga is needed to determine the sustainability of the fish and make it easier for fishermen to catch fish. This research was conducted in February-April 2020 by utilizing secondary data from the North Sumatra Province Fisheries and Maritime Service in 2010 - 2015 in the preparation of the Coastal and Small Islands Zoning Plan (RZWP3) in 2016. The result showed the potential of small pelagic fish that exist in Tapanuli Tengah and Sibolga waters there are 18 species with a total volume and value of production, namely: Sibolga is 23,699.2 Tons (Rp.382.45 Billion) and Tapanuli Tengah is 16,921.8 Tons (Rp. 254.37 Billion). Estimation of fish abundance in Tapanuli Tengah and Sibolga waters are classified in Medium and High. The types of fish in Tapanuli Tengah waters are: Restrelinger spp, Selaroides leptolepis, stolephorus commersoni and Mugil Sp. Whereas in Sibolga waters the types of fish that are classified as having high abundance are Stolephorus commersoni, Decafterus ruselli and Dussumeiria spp, while Restrelinger spp and Selaroides leptolepis classified is medium

The fishing equipment used in Central Tapanuli Regency is dominated by gill net fishing equipment. This research was conducted in July at the Fish Landing Site Kuala Sorkam Central Tapanuli Regency, North Sumatra. The research object used in this research is gillnet fishermen located in TPI Kuala Sorkam as resource persons, the fishermen are distinguished into fishermen, skippers and crew. The equipment used in this research is data collection devices, communication devices and laptops. The operation process of Gill Net fishing equipment has four stages, namely determining the location of fishing gound, net installation, net withdrawal, and the final process of moving the catch into the hold. Perception of Gill Net fishermen in TPI Kualla Sorkam generally fall into the "medium" category more than 50% of fishermen in that category try to comply with existing regulations but fishermen's knowledge of the size of fish worth catching is still lacking.
