Aims: Indawgyi Lake, in northern Myanmar, is the country’s largest lake and among the largest in Southeast Asia. Although the lake’s fishery provides an important source of food and livelihoods, relatively little is known about the status of its fishery and how human actions are affecting it. Further, some basic information on fish populations has not been documented, such as the extent to which fish migrate, either downstream toward the Ayeyarwady River or into the lake’s tributaries. Similar to other lakes in the region (e.g., Inle Lake in central Myanmar), the fishing practices of Indawgyi Lake appear to be intensifying. Thus, improved understanding of the lake’s fishery and fish-migration patterns can inform future management.

Study Design:  To gather preliminary information, we surveyed 6 villages around Indawgyi Lake collecting Traditional Ecological Knowledge (TEK) about the migratory behavior of fish and current state of the fishery.

Place and Duration of Study: Hepa, Hepu, Lone Ton, Lonsant, Mamon Kaing, and Nyaung Bin along Indawgyi Lake in Myanmar

Methodology: We interviewed in large groups at 6 villages (approximately 60 fishermen overall), aggregating results into the six village groups due to the consensus style of interviews. We performed subsequent analyses using Google Earth Engine.

Results: Fishermen reported that nearly all the fish they commonly catch are migratory, with most using upstream tributaries for spawning during the wet season. Fishermen also reported that, although most tributaries remained in good condition, several have been severely impacted by land-use changes, including gold mining. Fishermen consistently reported that harvest levels have declined dramatically in the past two decades even as they deploy more nets. Across the villages interviewed, the top recommendation to combat declines was to increase/strengthen enforcement of regulations.

Conclusion: This research demonstrates the utility of TEK to provide preliminary information on poorly studied systems that can inform conservation and management.

Purse seine is one of the fishing gear that has been used by PPN Muara Angke fisher to catch pelagis fish. The selectivity of purse seine was still being researched until now . This research was conducted  determine the selectivity of purse seine fishing gear with parameter the length of Euthynnus affinis, weight and numbers catch on purse seine fishing gear landed in PPN Muara Angke. The research used a survey method with quantitative descriptive analysis. The sampling method used in this was purposive sampling and random sampling. The data collected during the research were primary data and secondary data. Primary data included the number and weight of catches, fork length of Euthynnus affinis from five purse seine fishing vessel in PPN Muara Angke. Secondary data included production data of purse seine catches from 2015-2019 and vessel data obtained from Central Port Management Unit Jakarta and PPN Muara Angke. Purposive sampling used for the number of catch, weight of catch, production of purse seine catch from 2015-2019 and purse seine fishing vessels data. Random sampling used for fork length Euthynnus affinis fish, 250 samples were taken randomly on one purse seine fishing vessel. The research results pusre seine fishing gear which was landed at PPN Muara Angke was not selective due to the percentage length of the Euthynnus affinis was worth, proportion of amount and weight less than 60%.

This research was conducted to determine the water quality of Situ Ciburuy based on the plankton community as water quality bio-indicator. This research used the survey method and the observation result data were analyzed descriptively. The abundance of phytoplankton is about 340 – 8913 ind/L indicates that the abundance of phytoplankton is moderate and the abundance of zooplankton is about 7 – 30 ind/L indicates that the abundance of zooplankton is low. The Simpson diversity index for the phytoplankton group ranged from 0.29 – 0.33 and the Simpson Diversity Index for the zooplankton group ranged from 0.42 – 0.56 while the Simpson Dominance Index for the phytoplankton group ranged from 0.67 – 0.71 and the Simpson Dominance Index for zooplankton ranged from between 0.44 – 0.58 which indicates Situ Ciburuy is in an unstable condition. Based on the value of the Saprobic Index ranged between (-0.2) to (0). Situ Ciburuy belongs to α / β – mesosaprobic phase and categorized in the moderately polluted category.
