Zanzibar, Tanzania - Several hundred dolphins washed ashore this week on Friday in Tanzania's semi-autonomous Zanzibar archipelago died of natural causes, marine experts said on Saturday.
Narman Jidawi of the University of Dar es Salaam's Zanzibar-based Institute of Marine Sciences said at least 300 dolphins that were washed ashore on Friday had migrated from Indian Ocean waters in the southern African region.
"The results of our investigations carried out since Friday shows that the dolphins died of natural disaster known as confused eco-location. Since the dolphins move in pools, and we think they were looking for food, unfortunately they were trapped or stranded during the tides," she told AFP.
"We believe that the dead dolphins are the immigrants from Southern Africa. They are not Zanzibar dolphins so Zanzibaris and specifically the tourism department should not worry, we still have our dolphins," he added. "However, we are still continuing with investigations."
Fishermen were loading them on boats to toss them into the sea
Fishermen and residents on Kendwa, Tazare, Kigunda Nungwi - about 50km north of the Indian Ocean islands' capital - were seen disposing of the carcasses of the dead dolphins that had started to rot.
Fishermen were loading them on boats to toss them into the sea, while some residents were burying and carring home for food, despite warnings from the authorities against consuming them.
"The dead dolphins have started to stink and since Friday evening residents started burying them, unfortunately it is difficult to bury all the dead dolphins because they are many," Zanzibar resident Abubakar Mirando told AFP.
He added that some hungry residents carried large chunks of dolphin flesh to eat. - Sapa-AFP
