A researcher analyzes the water in a fish pond at a water quality and feed analysis lab of the Central Laboratory for Aquaculture Research in Sharqia province, northeastern Egypt, on Sept. 1, 2021. At a massive Egyptian fish farm in an open field with dozens of ponds of different sizes, fishermen were spreading their nets to collect the Nile tilapia fish and sort them out for sale based on their size, returning those too little back to ponds for further growth. The research ponds belong to the Central Laboratory for Aquaculture Research (CLAR), which is based in Sharqia province and belongs to the Agricultural Research Center of the country's Ministry of Agriculture.
