Illegal fishing takes place when vessels or harvesters operate in violation of the laws of a fishery. This can apply to fisheries that are under the jurisdiction of a coastal state or to high seas fisheries regulated by regional fisheries management organisations (RFMO). According to FAO Fisheries and Aquaculture Department, illegal fishing has caused losses estimated at US$23 billion per year with about 30 percent of illegal fishing in the world occurring in Indonesia alone.
