Relationship Between Mangrove Density And Mud Crab Density (Scylla Serrata) In Tungkal Satu Tungkal Ilir Village Tanjung Jabung Barat

The mangrove area of Tungkal Satu Village is characterized by diverse habitats supporting various species, particularly mud crabs. This study aimed to determine mangrove species density, mud crab density, and the relationship between mangrove density and mud crab density, while also considering environmental parameters in the waters of Tungkal Satu Village. The research method employed purposive sampling at three points, with an initial survey to determine vegetation observation sites based on previously known characteristics or properties of the vegetation. The results revealed mangrove tree density ranging from 466 to 1,400 ind/ha, indicating sparse to dense coverage. Mud crab density ranged from 533 to 900 ind/ha. The relationship between mangrove density and mud crab density showed a positive correlation, represented by the linear equation Y = 0.3728x + 342.4, with a coefficient of determination of 0.9361 or 93.61%. This suggests that mangrove density significantly influences mud crab density.
