Abstract:
This research was conducted to determine how strong the effect of mangrove density on the bivalves community in particular in abundance. This research was conducted in March 2022 to April 2022. Data collection is carried out at three stations located at upstream, middle and downstream. Each sample station collected is a bivalves sample and data mangrove observation. Bivalve samples using a 1 mx 1 m transect on the plot observation of mangroves 10 m x 10 m. The results of the study showed that the bivalves found there are 8 types of bivalves, namely; Mactra violacea, Perna viridis, Mactra chinensis, Polymesoda erosa, Geloina expansa, Isognomon ephippium, Anadara antiquata and Polymesoda bengalensis. Station 1 with bivalves abundance of 960 ind/m² with mangrove density 1300 ind/ha. Station 2 with an abundance of 680 ind/m² bivalves with a mangrove density 1800 ind/ha. Stations with an abundance of bivalves of 2,360 ind/m² with a density of mangroves 2200 ind/ha. The relationship between bivalves abundance and mangrove density using simple linear regression analysis with weak category results
