About Us
Preworth Fish Farm was established 2014, and is located east of Pretoria.
Preworth specializes in the production, distribution and sale of tilapia (whole fish), wholesale and retail.
We are developing fast growing strains of the Nile tilapia, Mozambique tilapia and Red breast .The fish are bred and cultivated in an intensive RAS (recirculating aquaculture system)
Tilapia is in high demand and the natural resources are deplenishing and we want to promote sustainable development of tilapia aquaculture, to attract, promote and increase the development of aquaculture industries and supply the demand for protein rich food, high in vitamins and minerals.
Tilapia is a pretty impressive source of protein.
In 500 grams of Tilapia it packs 480 calories. It is a mild white fish that is low fat and calories.
Even more impressive is the amount of vitamins and minerals in this fish. Tilapia is rich in niacin, vitamin B12, phosphorus, selenium and potassium.

Duckweed
Duckweed belongs to four genea: Lemna, Spirodela, Wolfia and Wolfiella (40 species worldwide).
The technical literature shows that duckweed has a strong potential as primary feedstocks for production of livestock and fish.
These plants grow rapidly and are high in protein and dietary minerals and low in fibre. Feeding trails show that they are suitable. Hey do not produce toxic alkaloids.
It is clear that the spices of this group are capable of a level of productivity closer to that obtained with micro-organisms than with other higher plants.
Description: Lemna minor, Wolfia and Spirodela.
Uses: Feed for humans and animals, Fuel, Fertilizer, Filtration, Water evaporation, Suppression of algae and mosquito larvae, vermiculture, medical uses and much more.
