A modified Secchi disk to measure water transparency in fishponds and determine the amount of plankton is helping smallholders in Sierra Leone to farm fish as part of profit-oriented agribusinesses.
Over the past three decades, the global aquaculture industry has risen from obscurity to become a critical source of food for millions of people, mostly through export. This boom has led scholars to question whether aquaculture contributes to the food security of poorer people in producing countries.
Aquaculture in Zambia is a significant industry, contributing around 30,000 metric tonnes, or 27 percent, of the country’s total fisheries production. Despite this, more efforts to farm fish are needed, as the lack of production is a major cause of Zambia’s low fish consumption, says Dr. Mary Lundeba, a WorldFish scientist and field researcher.
