Abstract:
The manual is based on the practical field experience of Gertjan de
Graaf and Johannes Janssen on the artificial reproduction and
rearing of the African catfish within FAO field projects in the
Central African Republic, The Republic of Congo, Kenya and
Nigeria. The manual is divided into five major sections dealing with
: 1) general biology, including feeding habits and reproduction; 2)
artificial reproduction, including induced propagation without and
through hormone injection; 3) fry nursing in earthen ponds,
including pond preparation, fertilization, feeding and management;
4) monoculture, including feeding methods; and 5) poly culture with
Tilapia. In addition, information is provided concerning the
economics of different fingerling and grow-out farming practices in
Africa, and concerning diseases and hybridisation.
