Tilapia farming systemsTilapia farming systems
Most Tilapias are still raised in pondsMost Tilapias are still raised in ponds. . There are There are a large number of farming systems, mainly a large number of farming systems, mainly aiming at the reduction of the excessive aiming at the reduction of the excessive reproduction of Tilapia:reproduction of Tilapia:
• Mixed cultureMixed culture• All male, hand sexedAll male, hand sexed• All male sex reversedAll male sex reversed• Mixed culture with a predatorMixed culture with a predator
EconomicsEconomics
Local economics and consumer Local economics and consumer preferences determine the financial preferences determine the financial success and risk of a Tilapia farming success and risk of a Tilapia farming systemsystem

The basis of TFST The basis of TFST
TFST is based on:TFST is based on:
• Population Dynamic ModellingPopulation Dynamic Modelling:: FFollows ollows birth, mortality and growth of the Tilapia birth, mortality and growth of the Tilapia you stocked in your virtual pond you stocked in your virtual pond
• Individual Based ModellingIndividual Based Modelling: F: Follows ollows each individual Tilapia in your virtual each individual Tilapia in your virtual pondpond
Inputs for TFSTInputs for TFST• Pond sizePond size• Stocking densityStocking density• Number of rearing daysNumber of rearing days• Sex distribution and size stocked fingerlings at startSex distribution and size stocked fingerlings at start• Feed typeFeed type• Mixed culture with predatorsMixed culture with predators• Predator stocking density and size of predatorPredator stocking density and size of predator• The number of rearing periods and simulation per rearing The number of rearing periods and simulation per rearing

TFST has two modulesTFST has two modules• The main simulation moduleThe main simulation module: with : with
specific inputs a simulation can be specific inputs a simulation can be carried out numerous times, providing carried out numerous times, providing detailed outputs and its variationdetailed outputs and its variation
• The optimisation moduleThe optimisation module: this module : this module allows you to search for the best allows you to search for the best farming system, once you have farming system, once you have provided your own economic dataprovided your own economic data
