Communities in Patra Manggala Village, Kemiri Subdistrict, Tangerang Regency, Banten used to think that the presence of mangroves disturbed tiger shrimp culture. Large scale mangrove tree felling had also been carried out in this area. In 2006, the harvest of tiger shrimp reached 20 kilograms per day. But after the absence of mangroves, shrimp yields gradually decreased. Even shrimp farming in this area was really dead.
