This structure shown in the photo which was introduced in 1985 is known as a Fish Aggregating Device. Fish aggregating devices (FADs) are floating objects that are specifically designed and located to attract tunas, and therefore allow fishers to find them more easily.\u00a0<\/span><\/div>\n
<\/div>\n
The aim is to relocate the artisanal fishermen from the heavily exploited lagoon areas to the open sea, with a view to increasing their catch and concurrently reducing fishing pressure in the lagoon.<\/span><\/div>\n
<\/div>\n
\n
The Fish Aggregating Devices (FADs) designed in Mauritius is composed of reinforced plastic floats mounted on two strings of polyamide rope and moored to the sea bed with polypropy-lene rope. 27 FADs have been set around the island at distances of 3 to 10 nm from the shore\u00a0and at depth ranging from 400 to 3 000 m.<\/span><\/div>\n
<\/div>\n
Deep-water FADs attract or aggregate Skipjack (Katsuwonus pelamis<\/em>), Yellowfin (Thunnus albacares<\/em>), and Bigeye tunas (Thunnus obesus<\/em>) and also sharks, Dolphin-fish, Rainbow-runner and other smaller fish.<\/span><\/div>\n
<\/div>\n
No one understands exactly why tunas are attracted to FADs, but the ropes, floats and the other materials used presumably mimic the build-up of driftwood and seaweed found naturally in the sea.<\/span><\/div>\n<\/div>\n
