Fry collection of Nile tilapia (Oreochromis niloticus) in concrete tanks – Aswan (Egypt)- Video

The video shows how tilapia fry is collected from concrete tanks which belong to a tilapia hatchery in Aswan. The method shown in the video targets to minimize the handling stress during this operation especially tilapia fry are delicate in relation to such operation. Fry collection starts with tank drainage till water level is significantly low. Water lowering is done gradually with no stops in order to force fry to follow the lowered water towards a collection sump located in the corner of the tank. Once fry are crowded in the catch sump, the fry are gently scooped out. The water sprayed from the fry end of the tank targets securing a continuous water current during the crowding process of tilapia fry.
