This video clip on sampling of Nile tilapia, Oreochromis niloticus shows clearly the morphological characteristics of a 300-400 g specimen of Nile tilapia especially the bands on the tail.
Note: the credit of these video clips goes to colleagues who participated in aquaculture training courses organized by the Egyptian International Centre for Agriculture (EICA). I am trying to identify the colleagues who donated me these clips and I will personalize the credits if I am successful in my attempt.
