Zimbabwe's depleting fish stocks threaten jobs and food

22 August 2014 Last updated at 16:17 BST

There has been a steep decline in the stocks of a key fish in Lake Kariba, which lies on the border between Zimbabwe and Zambia.

Millions of people in the region eat the fish in question - kapenta - in their daily diet, and thousands of fishermen earn their living by catching it.

But now, over-fishing - together with an increase in freshwater crayfish, which eat kapenta eggs and hatchlings - is something that could cost future jobs and food security.

Brian Hungwe reports for Africa Business Report, from the Zimbabwean border town of Kariba.
