The rich marine life off Tanzania's coast is coming under threat because of blast fishing, according to environmentalists.
The technique sees fishermen use explosives to maximise their catch.
Although illegal, the practice is used along the entire Tanzanian coastline from Mtwara to Tanga, and off north Zanzibar.
