93

Professor Francis K. E. Nunoo, a Senior Lecturer at the Department Of Marine And Fisheries at the University of Ghana (UG), has outlined possible factors that led to the current fish mortality in Ghana.

He mentioned temperature, lack of oxygen, excessive sounds as a result of oil drilling, the introduction of poisonous drugs into the sea, the outbreak of diseases in the sea as possible factors that led to the death of a number of dolphins and other fish species.

The Ministry of Fisheries and Aquaculture Development dispatched a team from the Fish Health Unit and the Fisheries Scientific Survey Division of the Commission to investigate the fish mortality at the Osu Castle beach in Accra and the Axim beach in the Western Region.

A statement signed by the Executive Director for the Fisheries Commission, Michael Arthur Dadzie (Esq), confirmed that when the team arrived at the Osu Castle beach, there were dead small pelagic and demersal fishes at the beach.

According to him, initial observation of the fishes, however, showed no wound or lesions on the body of the fishes.

He revealed that samples of the fish as well as sea water have been collected on ice to be examined critically at the laboratory.

In an interview with Kaakyire Ofori Ayim Professor Francis K. E. Nunoo, a Senior Lecturer at the Department Of Marine And Fisheries at the University of Ghana (UG), explained that the health of persons who have eaten fish are at risk, especially when the cause of the mortality is yet to be ascertained.

According to him, the Department Of Marine And Fisheries at the University of Ghana (UG) is conducting its own test on some of the species and that the report will be ready by tomorrow April 9th 2021.

He called on persons using the fish for “salted” fish to desist from the act.
