Yes, there assuredly is. Tilapia is an internationally traded, high-quality commodity. It is by no means a 'trash fish', as is maasbanker, for example. Tilapia compares favourably with hake in the quality of its flesh and lends itself to preparation in many ways. The traditional rural market is for small, whole, wild-coloured fish of 100g to 300g. The urban end of the market is for red tilapia of 450g to 600g.
