This video clip was taken in a fish farm located in Kafr El Sheikh, Egypt. The sampling practice highlights the followings:
The feed has been used to attract tilapia to the chosen place for sampling.
The operation was done very fast
When large biomass was caught in the seine, the release of a portion of caught fish was allowed to minimize the sampling stress
It is obvious; the sampling in this video was a sort of demonstration in a training program. Thus, not much effort was taken to reduce the jumping of specimens over the sampling seine to ensure a representative sample.
