The literature review involves in acquisition of knowledge from human expert books; document, journal, and existing system. Data collection leads to create freshwater fish knowledge base. The inference engine proposed in this study is based on forward and backward chaining to construct a decision tree. Certainty factor uses to makes some simple assumption for creating confidence measures. From the data gathered a Malaysia freshwater fish expert system prototype is developed.
