Tilapia farmers taught to clean up janitor fish
Turn them into fish meal and leather.
This was the science department’s instructions to tilapia farmers in Pampanga who were in a quandary as to how to combat the janitor fish that have been preying on their fish.
Aside from janitor fish, the tilapia farmers also raised during a seminar with experts from the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (PCAARRD) their problems with soft-shell turtles and migratory birds that eat their fish.
Aside from the predators, the tilapia farmers also have problems with high cost of feeds and poor water quality.
The PCAARRD experts told the farmers to manually pick up the janitor fish from the tilapia pons and make money from them by turning them into fish meal and fish leather.
They said soft-shell turtles could be shocked with an electric fishing device while other frightening device could be used to scare off migratory birds.
The farmers were also taught how to use filtration from water sources.
