Abstract

The mangrove ecosystem on the coast of Youtefa Bay is very beneficial for the survival of the Indigenous people in Enggros, Tobati and Nafri villages, as well as residents of Jayapura City and its surroundings. The purpose of this study was to calculate the diversity and population of fisheries in a polluted mangrove ecosystem. The research was conducted in the waters of mangrove ecosystem in Youtefa Bay, Jayapura City, Papua. Fish data were collected at 10 locations, using gill nets with a mesh size of 1.5 inches with a length of 150 meters and 2 inches with a length of 150 meters. Physical and chemical parameters of the waters were also measured in each location. Data analysis used the Shannon-Wiener diversity index, dominance index, fish abundance, and fish species composition. This study only found 12 species and 10 fish families, with an abundance of 188 individuals/ hectare living and associated with the waters of mangrove ecosystem. There is a reduction in the level of diversity and abundance of fish in the waters of the mangrove ecosystem in Youtefa Bay, due to damage to the ecosystem, conversion of ecosystems, and pollution that occurs in the decomposition of the mangrove ecosystem. These fishery resources will recover if the mangrove ecosystem is restored by increasing the area of the mangrove ecosystem and controlling waste.

Abstract

This research was conducted to test the mangrove crab of Sesarmidae family as bio-indicator to assess health status of mangrove ecosystem in Youtefa Bay of Jayapura. Conducted since March-August 2017. Conducted in 3 stations namely St. Enggros, St.Tobati, and St. Nafri. Using the quadratic transect method (1x 1 m) and the quadratic transect (10 x 10 m). Data were analyzed using index of diversity, dominance, evenness, abundance, density, simple linear regression and test criteria of indicator species. The result of the research found the level of mangrove diversity in Enggros Station with the value of index 1.9 then Tobati and Nafri Station of 1, 4 with abundant diversity level. The density of mangroves in the three stations is obtained by Enggors: 1455.6 trees / Ha, Naftri: 1477.8 trees / Ha, and Tobati 1033,5 trees / ha with moderate density categories and good ecosystem health conditions. The biological criteria indicator test shows that the Sesarmidae crab meets the six criteria of the indicator species, so that it can be designated as a species indicator of the health status of the ecosystem.
