Huge fish fences which are commonly used in tropical seas are causing extensive social, ecological and economic damage and are threatening marine biodiversity and human livelihoods, according to a new study.
Huge fish fences which are commonly used in tropical seas are causing extensive social, ecological and economic damage and are threatening marine biodiversity and human livelihoods, according to a new study.
Fish fences are a common type of traditional fishing gear regularly constructed from mangrove poles and nets spanning hundreds of metres which are placed semi-permanently in shallow habitats.
Using ecological, social and remote sensing methods, the research team examined the landings from fish fences over a 15-year period and assessed the health of condition of local seagrass, mangroves and reef habitats.
