AQUACULTURE MAKHATHINI
RESEARCH STATION
INTRODUCTION
• AQUACULTURE CAN
BE DEFINED AS THE
ARTIFICIAL
PROPAGATION OF
AQUATIC SPECIES
e.g. fish
objectives
• To provide fingerlings to the small-scale
farmers
• Promotion and demonstration of fish
farming
• Evaluation and implementation of
aquaculture systems
Fish species
• Tilapia rendalli
Fish species
• Oreochromis
Mossambicus tilapia
Fish species
• Claria Gariepinus
• ( Catfish )
Aquaculture production Systems
• Earthen pond system
integrated with poultry
Aquaculture production systems
• Intensive tank
systems
Aquaculture production systems
• Cage system
Research projects
The effect of aquaculture on water
quality used for irrigation
Project objectives
• Determine the impact of water quality
changes on fitness – of- use for other
uses.
• To establish the interaction between
aquaculture and irrigation activities.
• To assess the resultant water quality.

Research project
The use of frozen ram testis for sex
reversal on Oreochromis
mossambicus
Objectives
Production of monsex fish – Why ?
- Male grow faster than females
- Prevent breeding which result in stunted
growth.
Ornamental fish
Conclusion
• As the world’s
population and
diseases increases,
there is a huge
demand for protein.
