Many green mussel farm were located in Bang Taboon coastal area more than any other coastal area in Thailand. Therefore identifying the key factors that influence on this situation is very important in the future farm business. Then the object of this study is to investigate the correlation between nutrient distribution and mussel growth in the different distance along the coastal area of Petchaburi province in Thailand for both low and high tide during November 2017(Rainy season).The water quality had been sampled and analyzed in six different distance at 0.5,1,2,3,4 and 5 km. Six parameter have been identified as follows: calcium silicate, ammonium, phosphate, chlorophyll a, chlorophyll b and phytoplankton. The study showed that nutrients (ammonium, phosphate, calcium silicate).The correlation showed negatively related to distance(r=-0.499,-0.709,- 0.789,P<0.01) but chlorophyll a ,chlorophyll b and phytoplankton do not correlate with distance (r=0.014,0.411,0.029, 0.-029, P > 0.01).The study express that the niched located for growing mussels is at 2-3 km. from the coastal. The result showed that the growth of mussels largely influence by availability of diatom, the food source of mussels, that depended on suitable concentration of nutrients as follows calcium silicate, ammonium, phosphate and suitable light for photosynthesis obsering form phytoplankton.
