The existenece of nutrient is highly affected by human activities and causing the amount of chlorophyll-a which is the indicator of water fertility.

Rasio N/P muara Serang mempunyai nilai lebih tinggi dibanding Wiso. Kondisi ini menyebabkan konsentrasi klorofil-a muara Serang dua kali lebih tinggi dibanding Wiso.
