I. Introduction The Janitor Fish infestation which has plagued Pinagbarilan Baliwag, Bulacan’s irrigation is now threatening to run among on the delicately balanced ecosystem. Janitor Fishes were treated as pest in fish farming. This type of fish contributes to the severe erosion of river banks, a predator to some local fishes and a competitor of food for the local fishes. The fisher folks have been suffering from low catch due to the rapid growth of population of Janitor Fish. They consider these ugly-faced fishes as their enemy and they are calling-out for total eradication of these pests. As a solution, emulsifying fish is conducted. Fish emulsion comes primarily from the processing of a fish called the menhaden, but it can theoretically come from many types of fish. These fishes are cooked and pressed to extracts their oils, and some of the solid by-products are further boiled to create fish emulsion. Fish emulsion is mixed with some chemicals including phosphoric acid to make sure it is suitable for storage and shifting, but chemicals are use in small amounts. Fish emulsion is still certified as organic in origin. Emulsified fish fertilizer is mainly a great soil conditioner and a great bacterial food to help feed the soil micro herd. Liquid fertilizer is an answer for a fast absorption for soil. Emulsified organic janitor fish fertilizer is acidic in nature, therefore, it is an excellent to salt sensitive plants without damaging them. Fish fertilizer is one of the most powerful liquid organic fertilizers that can be fed to plants. Emulsified organic fish fertilizer is acidic in nature , therefore, it is an excellent way to feed to salt sensitive plants without damaging them. a.) Background of the Study This study was conducted to help fishermen to alleviate their problem on
