Abéné : From construction to immersion 23/07/2015

The first immersion of 100 artificial reefs built by the Management Committee and GIE des Eco-gardes of the Marine Protected Area of Abene (AMPA) took place on Saturday 6 June 2015. For the very first time, the AMPA started the rehabilitation of a marine habitat likely to serve as egg-laying and nursery sites for several fish species, notably demersal species.

From construction to immersion: (continued)

The building of artificial reefs followed the procedure below:

  • Purchase of rolls of galvanized wire netting ;
  • Creation of stone blocs to weigh down the reefs ;
  • Collection and transportation of Crepidula shells;
  • Wire netting rolls unfolded and cut into 1.2 m-pieces ;
  • Wire netting folded and weaved with a galvanised iron wire in the form of cages likely to capture shells ;
  • Small cages filled with Crepidula shell and closed with a galvanized iron wire: the artificial reefs are ready;
  • Transfer of the reefs on board two boats. The first boat transported the reefs from the beach to the second one that is bigger. The second boat had to convey the reefs to the points of immersion.

The reefs are weaved in rows of 20 with a cord and immersed perpendicularly to the coast to prevent them from running ashore due to the swell.

Through this procedure, 200 reefs have already been immersed to date and the same quantity is expected to be immersed during the course of July.

The execution of this first phase enabled the Marine Protected Area of Abene to immerse 100 reefs in a marine channel of the AMPA near the Djanah Village and 100 others between Abene and Niafrang. Phase II of this project provides for the immersion of at least 200 reefs in two different locations of the AMPA that will be determined in consultation with the fishermen of the area.

This Project is made possible thanks to small grants provided to RAMPAO members.
