This study aims to analyze the ecological status of ponds using the silvofishery model through water quality observations. This study used a survey method. The ponds observed were shrimp ponds located on the north coast of East Java, Indonesia. Water quality analysis method used STORET. The results of measurements of physical parameters show that the temperature ranges from 29-32 oC, for chemical parameters pH is between 6-8, dissolved oxygen is between 4-7 mg/l, nitrite is between 0.02-0.06 mg/l, nitrate is between 0.4-1.0 mg/l, and ammonia is between 0.3-1.9 mg/l. Based on the STORET analysis, the total score of class II quality standard and class III quality standard in site 1, 2, 3, and 4 are -8, respectively. Based on these data, the four sites are classified as class B water quality, which indicated lightly polluted for class II and III. This means that aquaculture activities with the silvofishery model are able to reduce water pollution due to fishery activities. It is also proven that site 1, 2, 3, and 4 have the same value. Furthermore, silvofishery cultivation can be an environmentally friendly cultivation model and continue to be used.
