Marine lake is a unique ecosystem. It focuses at four locations in the world. One of them is in Raja Ampat. Each lake have a unique character according to the level of connection with the sea. Lake Balbullol is the deepest lake among the sea lakes in Misool, alienated, and has never been studied. This study want to know the character of Lake Balbullol. Description of the lake is done by a series of field surveys and loggers recording to determine the physical character, water quality, and presence of the biota. Lake width was 1.94 ha and the maximum depth was 38 m. Temperature and salinity showed a homogeneous vertical profile, thus forming a holomictic type. During 6 months time series, the temperature was always warmer than at the ocean, as well as salinity. Although the distance between the lake and the sea is very close (<45 m), the tide on the lake was delayed 4 hours rather than the sea. Tidal amplitude was only 25% of the ocean. From measurement of the tides showed Lake Balbullol was isolated lakes, however, there were no biota as an indicator of isolated lakes exist. There were at least 7 soft corals with attributes many and abundant exist in this lake.

Mastigias papua is a jellyfish that is trademark of marine lakes. Ongeim’l Tketau Lake in Palau, Hang Du I Lake in Vietnam, Kakaban Lake in Kalimantan, and Lenmakana Lake in Raja Ampat Papua are exotic tourist destinations because of presence of these biota in the lake. Water temperature is very influential on the life of a jellyfish because of its mutual symbiosis with brown algae zooxanthellae. Mastigias has totally disappeared in several places due to water temperature increasing, including Lenmakana Lake in the West Monsoon 2017/2018 and 2018/2019. The absence of Mastigias in this lake will be explained by recorded logger data installed in the lake and at sea. Secondary data from NOAA and BMKG will be used to explain the condition of absence of jellyfish. Water lake temperature data showed an increase to 2.5oC when the Mastigias disappeared. Temperature increasing occur due to seasonal cycle patterns of lake water temperatures and weather cycles which change in time, the dry season occurs faster and the rainy season occurs slower. Conversely, in the West Monsoon 2019/2020, Mastigias still found in the lake. The rainy season which is 20 days faster than normal condition helps reduce the heat in West Monsoon.

The implementation of the fisheries moratorium has an impact on the shrimp industry, namely the cessation of shrimp fishing operations and termination of employees of some shrimp companies in the West Papua Province. The aim of this research is develop a shrimp fisheries management strategy at West papua Province after the end of the moratorium on fisheries so that the shrimp industry can contribute to job creation and increase local revenue. SWOT analysis is used to identify internal and external factors as the basis for the shrimp fisheries policy direction. Recommended strategies for managing Shrimp fisheries; 1) Increasing awareness of coastal communities towards environmental sustainability. 2) Optimizing the productivity of small-scale capture fisheries through improving the quality of fishermen's human resources. 3) Strict law enforcement and improvement of community based fish resource utilization monitoring systems, including improving the quality of HR supervisors. 4) Development of capture fisheries infrastructure, including fuel supply logistics systems. 5) Increased cooperation in fishing business through partnership programs, to ensure the sustainability of operational costs, and the development of business investment. 6) Development of value-added capture fisheries for the welfare of fishermen's income.
