Tracing the caption of this video, I was able to find out that this video was taken in a shrimp farm in Suez (Egypt) and shared with me unlabeled. The credit of the video should go to a friend who I do not remember
This video shows the harvesting of shrimp in a shrimp farm in Egypt. In this farm which is located in Suez, the post larvae used in this farm are collected from the wild. Green tiger shrimp, Penaeus semisulcatus and Penaeus japonicus are the main shrimp species in the farm. The harvesting as shown in the video is carried out during dark nights (moonless nights). In such harvesting method, a source of light is placed in a proper position to attract shrimp which are dragged by water current towards the light and enter a netting structure where they are scooped and processed.
