The relationship of redox potential to crustacea abundance at Bama beach of Baluran National Park, Situbondo, Indonesia

Crustaceans are invertebrates that generally live at the bottom of the water. Organic matter on the substrate that is crustacean food undergoes the process of reduction and oxidation to become a simpler form. The purpose of this study is to find out the potential relationship of redox (reduction and oxidation reactions) to crustacean abundance. The research method used in this study is an observation method. Soil abundance and oxidation are measured based on transects at three stations. The results showed that there are 10 types of Crustaceans with a total of 1320 individuals, while in Mangrove there are 4 types with a total of 92. The highest redox potential (reduction and oxidation reaction) value is at Station 1 transek 1 (ST1. T1) which is 62.5 mV, with mud soil texture. while the lowest potential redox value is at Station 2 Transek 3 (ST2. T3) 40.6 mV, with mud soil texture. the conclusion of this study is that redox potential affects crustacean abundance by 99.5 %.
