Abstract
Mangrove ecosystem is a habitat of mangrove crab (Scylla serrata). This research was conducted in mangrove ecosystem area of Karangsong Village, Karangsong Sub-district, Indramayu District. The purpose of this research is to know the abundance of mangrove crab, mangrove ecosystem condition and mangrove ecosystem relationship with mangrove crab in Karangsong mangrove ecosystem. The method used is descriptive explorative and station determination is done by stratified random sampling method. The results of the study found two types of mangroves namely Rhizopora mucronata and Avicennia marina. The mangrove conditions at the observed stations were classified as rare (broken). Mangrove density at station 1 has a value of 360 ind / ha, station 2 is 380 ind / ha, station 3 of 860 ind / ha and station 4 has a value of 480 ind / ha. Abundance of mangrove crabs at station 1 amounted to 280 ind / ha, station 2 as many as 340 ind / ha, station 3 valued 0 ind / ha and station 4 of 60 ind / ha. The relation between mangrove density with abundance Scylla serrata level of tree has value of coefficient of determination (R2) 0,10529 mean that between density of mangrove trees with abundance of mangrove no relation.
