This video was filmed during July 2014 in a private tilapia hatchery in Kafr El Sheikh, Egypt. The fingerlings shown in this video are for all-male Nile tilapia, Oreochromis niloticus. What could be drawn from the video is the observed healthy condition of fingerlings. Also, the size of fingerlings is relatively larger than those disseminated from the hatchery early in the growing season (e.g. May). Usually the demand on all-male tilapia is at highest during late April and the whole of May whereas this timing allows for a long growing season and heavier harvested fish assuming this is economically justified.
The temporarily holding would help in the conditioning of fingerlings for packing, shipping as well for allowing fish to empty their guts. However, excessive holding is not recommended as it turns stressing to fish due to their swimming against water current along with the energy requirement for that.
