The saltwater people depend on fish and other marine resources for food and income. But fisheries in the lagoon are under increasing pressure. Overharvesting is threatening important commercial species such as sea cucumber, trochus and hump-head parrotfish. The use of trammel nets, so-called “magnet nets”, is impacting the rabbitfish and emperor fisheries. Deforestation is leading to the siltation of the lagoon. And the cutting of mangroves is degrading nursery grounds and exposing the coast to storms. Several communities in Lau Lagoon have taken steps to use their marine resources more wisely. The village of Fumamato’o for example has declared a locally managed marine area where only sustainable fishing methods such as spearfishing are allowed.
