Tilapia Growth Chart

About 4 to 6 weeks from hatching, fingerlings should be about 1 gram, if culture temperatures are in the mid 80's (degrees F). The following table assumes that warm temperature range, moderate to aggressive feeding, in terms of percent biomass per day, and also assumes that fish stocking densities do not exceed 80kg per cubic meter (about 2/3rds pound per gallon)



This is the target average weight of the individual fish.
