Relationship between nutrient concentration and macrozoobenthos can indicate the level of fertility or pollution in the sea waters. The purpose of this research is to obtain nutrient concentrations in pore water, macrozoobenthos community structures, and the relationship between nutrient concentration and macrozoobenthos in pore water Ciletuh Bay. The research are using survey, purposive sampling and descriptive analysis method. The parameters observed in this research are nutrients including ammonia, phosphate, nitrate, nitrite, total N, and Total Organic Carbon (TOC). Analysis of population macrozoobenthos was determined by knowing abundance index and dominance index. From the results of the study, it has been found that two types of macrozoobenthos is Donax sp. and Nassarius sp which lived immersed, and its dominance influenced by sand sediment fraction. The higher concentration ammonia, nitrate, nitrite, phosphate, N-total, and TOC which is 0.028, 0.708, 1.663, 0.075, 3.066 and 1.4 mgL− 1 . The factor that most influences the presence of macrozoobenthos is the type of sediment and the closest concentration of nutrient is phosphate.
