Thousands of aquatic organisms, which a lot of fish Senghor (Toubacouta) Valley, and a unit of aquaculture in floating cages of the project Go Wamer probably died from lack of oxygen, revealed Wednesday of technicians of the Ministry of fishing and the maritime economy.
The head of the production Division to the national agency of aquaculture (ANA), Amadou Tidiane Camara, and the Coordinator of the project “Go Wamer”, Mamadou Thiam engineer went on the ground to ascertain the extent of the problem. On the site, the two men found a desolate scene with several dead fish floating on the surface of the waters of the San Valley.
In the presence of people in the village of Santhie Bera grouped in economic interest group (EIG) for the operation of the unit of aquaculture in floating cages in the Valley, two technicians have made withdrawals in waters in view further laboratory analyses.
“Today, we came to a preliminary examination to see the cause of this mortality. One measured the oxygen levels, the physicochemical parameters of water waiting to make accurate and in-depth analyses at the level of Dakar to see the exact causes of this problem,”said the head of the ANA, Tidiane Ahmadou production division Camara.
He said that the results of the preliminary review points to the level of oxygen in the water. “So, we suspect a low oxygen levels that would be the cause of mortality of 8000 fish just at the level of the floating cages Go Wamer project but also the waters of the Valley”, he said
He explained that the lack of oxygen would be due to a renewal of the waters of the valley station. “Given this situation, we will take the time to diagnose all causes of mortality before you continue the project with a new stocking”, added Mr. Camara
“It’s very painful to see these losses in fish, because we have in front of people very engaged in the operation of this unit of fish in floating cages,” says the Coordinator of the project Go Wamer, Mamadou Thiam.
Since the start of the project in 2013, he said, he has never known this problem of mortality found in the waters of the San Valley this year.
Unity of aquaculture in floating cages of the Senghor Valley “is a successful experience”, he stressed, explaining that “this is why the model is replicated in other localities of the Fatick Department as to Simal”.
“It ends in December 2017 and the ANA, as a technical arm, will take over to assist the populations of Santhie Bera ‘, he added.
The project Go Wamer activates in governance, management of marine resources and the reduction of poverty in Cape Verde, Gambia, Mauritania, Guinea, Guinea-Bissau and Senegal.
